Title: Grainfather
Post by: fishjam45 (Colin) on March 18, 2015, 03:04:12 PM
Anybody any opinions or comments about the "grainfather"?
I spotted it on Get'er Brewed earlier and it has more than caught my attention.  It's expensive but if it's as good as it says it is I would defo look into buying one.

I have to say, I'm quite interested too. It's a mash tun, combined with a kettle with a built in heat exchanger. Or am I missing something?

It seems a tad underpowered. I've seen a few videos and it takes quite a bit to get up to mash temp and boiling.

It looks to basically have everything in the one box.
Will look into it more tonight on the laptop, there's lots of videos and reviews on YouTube.

If the pump &/ element fail do you then have to buy a proprietary replacement from grainfather? Can you replace said components yourself?
That's something I will ask them.

What about the hops after boiling. Do you use a hop bag with this. :-\
Title: Re: Grainfather
Post by: beanstalk on March 18, 2015, 07:14:09 PM
In a video I saw you get a strainer discdisc with to sit the hops onon and stop them falling to bottom while boiling?

The fact you need another vessel to heat sparge water puts me off a little but looks great! I guess you can't have everything for that price!
Title: Re: Grainfather
Post by: dcalnan on March 18, 2015, 07:17:38 PM
It only has a 2000w kettle element, I say you'd be waiting ages to reach temperatures. I love the look of the brewbot, shame its so expensive.
Title: Re: Grainfather
Post by: fishjam45 (Colin) on March 18, 2015, 08:36:06 PM
Cheers for the replys so far Lads.

I emailed grainfather directly earlier re: repairs and they said its covered under a 12 month guarantee. Of course I mailed them straight back asking what happens outside of the 12 month guarantee period - Is there an Irish Repair Service? Can parts be bought directly from them?
I expect a quick reply as they got back to me quick enough after the first mail.

So, I need to think about the 2kw element and the amount of power it'll supply.
And hops post boil too.  Now for some more research. . . .

Videos posted 5 months ago, so he got his recently enough.  Thats a cork accent if I'm not mistaken?

Grainfather have promptly replied to my email again. They will be supplying get'erbrewed with spares and they will have a list of them available shortly.
They also assured me they have "a team ready to answer any questions / give technical advice when needed" - very reassuring and I'm delighted with their prompt replies to my questions. So far so good.

I have a 20ltr Burco at my disposal so that answers my sparge water issue.
Hops after boil issue? The pump filter prevents hops entering the counter flow chiller.

I see they have a cleaner http://www.grainfather.co.uk/#!online-store/c8k/!/Grainfather-High-Performance-Cleaner-500g/p/47629811/category=12389142 (http://www.grainfather.co.uk/#!online-store/c8k/!/Grainfather-High-Performance-Cleaner-500g/p/47629811/category=12389142) too.  I presume normal w5 or VWP wouldnt be suitable as its a SS vessel? Anybody any ideas for a cheaper, more easily accesible cleaner?
Title: Re: Grainfather
Post by: molc on March 19, 2015, 08:41:42 AM
The thing is, could someone build something like that for a good deal cheaper. It's a burco with an insert and an attached pump with an arm back to the top. The braumeister is very well engineered whereas this just looks - hacky
Title: Re: Grainfather
Post by: fishjam45 (Colin) on March 19, 2015, 11:14:53 AM
How much is the braumeister gonna set you back?
To me this is pretty much an all in one setup, apart from my small burco for sparge water.
Space is an issue with me too, this suits my needs. The idea of buying a readymade unit appeals also, the thoughts of building boilers etc again defo does not.
I think I'm pretty much convinced about it, they were hitting some great numbers if you read the review on the the Aussie Homebrew page that I linked earlier
Title: Re: Grainfather
Post by: Simon_ on March 19, 2015, 11:40:24 AM
I think it looks like quite well engineered considering it's price range. If you were to go out and buy all the constituent parts that it includes (food grade pump, cf chiller, 30 litre pot, element, stc200, crab cooker...) you're looking at about €500 and you'd have spend hours sourcing them all, more hours fitting it. Then you're left with this frankenstein collection of objects that takes up lots of space. With this you're getting something where all the parts have been engineered to fit and work together.

Saying that it looks underpowered and could do with some program-ability.

I would feel I was somehow cheating though. How long long before grain and hops come in Nespresso type capsules?

These videos where he's having to wrap it in a quilt to reach temperatures and draining the first runnings to a fermenter make me less enthused. You're as well off with your cheap gear if it's not up to what it's designed for.

I agree with you wholeheartedly - what free time I have I want spend brewing, not building something that may or may not work properly.
There seems to be an option for changing the controller in the pipeline. It suits me as is now anyway.

Title: Re: Grainfather
Post by: armedcor on March 19, 2015, 05:38:44 PM
35 minutes in the video to get 20 litres of water to 45 degrees? He wasn't even close to mash temp.  That is a bit of a deal breaker for me
Title: Re: Grainfather
Post by: molc on March 19, 2015, 05:39:01 PM
Yeah I totally agree about wanting an all in one unit that's low hassle and just works out of the box. I think this one is just too clunky and low powered/featured for me to justify the spend. At the very least, if it's going to be underpowered, it needs to be programmable so you can set it to mash while you're away, including a mashout to lock in the grain. That said, at least it can take 10kg of grain, unlike a braumeister
Title: Re: Grainfather
Post by: DEMPSEY on March 19, 2015, 06:04:13 PM
What  I do not like about the designs is the narrow layout. A modern mash tun is wider so as to allow you to have a larger floor area to drain from and despite hop bags and filters the best way to deal with hops is to whirlpool and allow the spent hops form up a cone in the middle and finally allow you to drain from the side. :(

The Braumeister doesnt seem to handle as much grain as the Grainfather does. 9kg v 6kg
BM also has the same 2kw heating element.

This choice is getting easier.  :)
Title: Re: Grainfather
Post by: johnrm on March 21, 2015, 12:07:25 AM
You can get a bigger grain bill into the braumeister than you think.
Once the starch is rinsed from the initial grist, you can pause the program, then add more.
Title: Re: Grainfather
Post by: Will_D on March 21, 2015, 08:22:39 AM
The Braumeister has an optional lagging jacket. Sugest the GF also would benefit.

It looks an interesting system with some design improvements over the BM. Also its a fairly modular system so you could probably swap out the STC controller for a more flexible Brewduino type controller if you wanted to. Also the pipe from the pump needs a quick disconnect as mentioned.
Also a rotary sparge arm.

There also seems to be some confusion about the boil/mash switch on the controller and when the STC is used for control and on one video I thought I saw another switch on the boiler itself (like on a burco - which I assume this is) being used to switch elements.


Hmm Am I getting interested in this?

Err Yes!!

Facebook group (https://www.facebook.com/groups/1557967401104380/) with existing users. Private group so you need to request to be added. Really interesting to see manufacturer improvements reaching users and user mods

One guy is running a modded STC1000 but apparently there is a different pid (https://github.com/matsstaff/stc1000pid) implementation from the same developer (Matts). I think the difference from the usual STC1000+implementation being that it beeps at you for the strike water / hop addition steps :)

The STC1000 slots in easily in place of the STC200

Here's the modded stc1000 firmware especially for single vessel brewing

So with this you can wake up just in time to mash in and then forget about it until you get prompted for the hop additions.
Title: Re: Grainfather
Post by: molc on April 13, 2015, 12:08:06 PM
Pretty cool. I would be interested in trying it into a brewpi spark as well, for a shiny touchscreen interface. The big thing is what is the control loop like on the grainfather? Is it just a simple breaker circuit for the element that's wired into the stc? Also how is the pump controlled?
Title: Re: Grainfather
Post by: armedcor on April 13, 2015, 12:23:38 PM
Pump just controlled by an on/off switch I think
Title: Re: Grainfather
Post by: Simon_ on April 13, 2015, 12:30:38 PM
The link above says

QuoteThe unpopulated terminal on the STC can be used as pump control. The firmware will put this output in high impedance to turn pump on and pull it low to turn pump off.

Alternatively I think it makes little difference if it's just a manual step. You turn on the pump when you mash in and turn it off when you mash out. You need be present for those steps anyhow so there isn't much benefit to automating it

The capacity is labelled as 30L although it might be a bit more. I've seen the manufacturers recommending to sparging up to 28L pre boil with ~3L/ hour evaporation the most you could probably stretch it to is 25L. With trub loss and dead space it's probably closer to 23L.

I suppose you could dilute it during the boil to end up with more if you really wanted to.

Tip for both BM and GF users for higher ABV Beers...

If you can only physically fit so much malt into your malt pipe.
Start your mash - run it until such time as the Flour is rinsed from your Malt and is now in solution.
Pump off - add more milled malt - pump on.
Title: Re: Grainfather
Post by: fishjam45 (Colin) on April 17, 2015, 02:34:43 PM
Nice one, cheers!
So it basically allows you to add a little extra malt?
Title: Re: Grainfather
Post by: johnrm on April 17, 2015, 05:25:50 PM
Pretty much.
I spotted this over on Braumeisters.net there's lots of other stuff there that would be applicable to GF too.

Sorry John, theres a few things I don't understand here.

Quote:

Start your mash - run it until such time as the Flour (what is Flour?) is rinsed from your Malt and is now in solution.

Pump off - add more milled malt (Err where? the pipe is full of spent malt! New malt needs another mashing) - pump on.

Title: Re: Grainfather
Post by: HomeBrewWest on April 17, 2015, 09:51:40 PM
With the Speidel, its probably easier but will still extend the brew day. Essentially you mash as per normal, remove the grain, refill the malt pipe and repeat but starting with wort instead of water. You can get very high ABV beers this way. Because its all programmed, its rather easy. You just have to be there when it tells you to do stuff.

So, lets say a normal beer takes 5 hours to get into a fermenter. A high ABV beer will take about an extra hour.

Its done as follows:
- program the Speidel to do a mash,
- when it asks you to remove the malt pipe then remove it, refill it and reset the program,
- carry on as per normal.

I've made many Speidel beers, but haven't done this yet. Mostly because we are developing recipes for micros, and high ABV beers are a problem with excise etc. so there is little demand for them. The extra time required is only the time for the mash schedule. With Speidels, this can tend to be more complex than basic infusion mashing (its a feature). But you could just set a simple 60 min mash schedule, and then you only lose an hour. At most, even with complex step mashing, its only another 20 minutes.

The Grainfather should be able to work this way too.

As a hombrewer, I am tempted to add 20% hours to brewday to get close to double abv. But only if the end product is still a great beer.
Title: Re: Grainfather
Post by: HomeBrewWest on April 17, 2015, 10:25:12 PM
Yes, simples. Use less water! These systems usually do close to full volume at up to 7.5% ABV without extra grain additions anyway.

Still, the attraction of big beer AND big volume is that, if you can double output, then its one brewday instead of two. Or its one brewday plus a "free" brewday to try out something new.

An analogy is winemaking, I've never made a 6 bottle kit because it takes almost the same time and effort as making a 30 bottle kit. Actually, wine making is easier because you can concurrently make a selection of several 6 bottle kits in one brew day! In theory.

A quick Q,

I'm putting together the money for a Grainfather and was just wondering...those of you with a Grainfather, or have one on preorder, do you have a fermentation chamber?

At the minute I don't, and the thought occurred, am I putting the horse before the cart so to speak? Should I have a ferm chamber before I fork out €830 on the Grainfather? ( It's not really going to stop me as I have my heart set on one :) ) but I just wanted to know what others think?

I was thinking of ordering a grainfather but wouldn't worry overly much about a fermentation chamber personally unless I'm lagering. All my AG ales and stouts I've been really happy with in just an fv and a heater.

A quick Q,

I'm putting together the money for a Grainfather and was just wondering...those of you with a Grainfather, or have one on preorder, do you have a fermentation chamber?

At the minute I don't, and the thought occurred, am I putting the horse before the cart so to speak? Should I have a ferm chamber before I fork out €830 on the Grainfather? ( It's not really going to stop me as I have my heart set on one :) ) but I just wanted to know what others think?

Cheers
Great beers can be made with any equipment, if you focus on proper yeast pitching rates and temperature control .I'd go as far as to say forget spending on anything else until you can maintain a consistent fermentation temperature. Remember, as many greater minds than me have said, you don't make beer, yeast does.

I haven't brewed since I ordered this so alot of pent up brewing to do. I have to do my batch for the NCB barrel and I really want to do an RIS. There's a kit included with crushed grains. Think it's a Saison Kit I requested so might as well do that first.

Nice one, mine should arrive today (fingers crossed)  :)

My pot isn't big enough for heating a large amount of sparge water as I only did 1 gallon batches, so I went ahead and purchased a 20 ltr Catering Urn online for €85 delivered.

This should hopefully free up even more time and avoid me standing at the hob with a thermometer in hand. It also has a keep warm feature, so once you hit temp it will hold it, so you're ready to sparge once your mash is done.

It's not essential, but should make brew day a little quicker/easier!

Ok, couldn't resist a quick unpack and play!

First observations:

Very well packed
Very good clear instructions
Very well made - good quality stuff used.


First point of assembley to note is fitting the perforated plate to the botom of the Malt pipe:

Page 5
Step #4:
The silicon ring seal wants to unroll itself from the perf plate(18) as you push it down. Wet it with water, hold it at 90 degrees to the bore and genfly slide down to just off the bottom then gently rotate it to sit on the bottom. Gently help it to bed down.

Step #5:
To fit the overflow bottom pipe (23) stand the malt pipe on a work surface, slide it towards you so tou can pop in the tube and do up the nut. Be gentle because as in step 4 above the silicon tube wants to unroll.

Probably the same may happen at page 9 step #7 but by then th pipe will be well wet and there will be grain about so probably will be well lubricated
Thats all for now
Title: Re: Grainfather
Post by: Simon_ on May 13, 2015, 12:26:01 PM
What do you make of the 'mini bar drink lid' that's meant to sit on top of the overflow pipe during mashing. I read about it previously and thought it was something that resembled a mini bar drink lid. But it really is exactly that.

It's the only blight I can see on what looks like a really well engineered machine
Title: Re: Grainfather
Post by: Will_D on May 13, 2015, 04:44:17 PM
Next point:

Filled with 17 L of water and set the STC to 75C (a mash-in temp)

On switching on the pump it didn't pump! A bit of sucking and blowing sorted it out! Its now pumping fine. This is probably coz its new and not even had the (recommended) first cleaning cycle. But when you first run the pump make sure its not running dry.
Title: Re: Grainfather
Post by: beanstalk on May 14, 2015, 08:03:54 AM
I love the tap fittings! But I did think, upon assembly, that the silicone connection for inserting the pump pipe and sealed with a hose clip was strange. I wasn't sure how far to push the pipe down, and when I pushed on it to tighten the screw the connection now sits kinda weird.

Other than that, a beautiful machine. So shiny and looks pretty durable too! :)

It needs to go all the way down so that the two pieces that the screw(26) fixes together are in fact together. Now when I first assembled the pipe the valve handle was facing away from me - the valve was slack on the pipe and just needed a half tun or so to be nearer the control box (I call this facing me).

On a more worrying note there is no mention of how to clean the pump if its ever needed!

Will - hopefully we won't have too.

I had a play with it last night, ran the cleaner then Starsan through it.
Very happy with it so far and looking forward to getting my first brew on. 
Found it a fiddly when cleaning - the removing and reattaching of the chiller then the arm to run the cleaner then Starsan through was the only small issue I found,it's more my laziness than anything else though  :)

Title: First run
Post by: Simon_ on May 15, 2015, 10:20:07 AM
So I turned it on for the first time last night and did a cleaning run with it.

I was being quite careful not to let the pump run dry so as soon as it started sucking air I turned it off. Problems with this is that quite alot of wort is going to be left in the counter chiller. Also the Grainfather has quite alot of deadspace. Is shutting off the pump the second it appear to be sucking air the right thing to do? Do I just have to live with the amount of wort lost to the deadspace and CF chiller?

Also when I disconnect the recirculation arm or CFC a fair bit of liquid dribbles out. That's going to be messy when it's sticky wort. Is this the same for everyone?
Title: Re: Grainfather
Post by: fishjam45 (Colin) on May 15, 2015, 10:40:07 AM
Did you take a measurement of what's left in dead space?

Watch the videos, he shows how the wort will syphon back into the boiler.
Title: Re: Grainfather
Post by: Simon_ on May 15, 2015, 11:13:13 AM
Ah true. Had seen that but forgotten about it. It's explained here  (https://youtu.be/sc_RigwCPLA?t=1647)
Title: Re: Grainfather
Post by: Will_D on May 15, 2015, 11:18:53 AM
Make sure that the plastic pipe is in free air, then when you switch off the pump the liquid should syphon back.

As the pump rotor is wet from the wort and is probably sucking a little liquid as well as a lot of air its not really running dry. Also tilting the GF will allow more liquid to be pumped out.

This aspect of the hop filter (relatively small area but quite high off the bottom) is not the best part of the design. On the forum there are a number of reports of the filter clogging from hop leaves. A T shaped 1/2 bazooka type ss woven tube coiled round the bottom would be a lot better. Most people on the web use Hop socks or SS hop balls. (Have already ordered 2 from GBrewed)

When it comes to cleaning the chiller they have got it wrong. They say to just let the cleaner syphon out of the tube. Well imho they have the coil upside down! Yes its correct for chiller but not for back syphoning the liquid from the coils. All those gurgles means there's a lot of CF left in the coils. Not a good idea.

So my solution is:

1. Coil upside down so the inlet connected to the pump is at the bottom - this allows natural drainage - not sucking.
2. Recirc. as suggested.
3. At end of cycle have 5 litres of clean water ready.

4. Now the juggling act:
Switch off the pump, and as soon as the liquid in the outflow pipe starts to sysphon back, allow a 6" air bubble in the pipe then into the clean water, syphon say one liter, allow bubble to form and repeat until all clean water has run through the chiller. The reason for the biblle is to try to clean the walls of the tube. Its what I do when I clean my lines. Also when you see the first bubble at the other end you know that all of fluid A is replaced by fluid B. Useful when they are the same colour

You should now have a flushed empty chiller.

Ok you have diluted you CF but so what.

Also they say to clean coil first for x mins, drain it, and then recirc for y mins?

Why not just recirc through coil for x+y?

Anyways hope this helps

Once you turn off the pump, the wort within the CFC should be pulled back down in to the GF. I read online that they account for the dead space loss when you use their calculator (http://www.grainfather.co.nz/#!brewing-calculators/c1vp9) (or was it the Beersmith profile, I can't remember exactly).

I checked my STC-200 reading and it is spot on at 76C!

Note the -200 only goes up t0 90C so boiling water is not an option. Plus calibrating at zero in ice/water is probably not worth doingt!

Calibrate against a known reference thermometer at say 40C and 75C

I've had no dribbles! Is it coming out when you disconnect, or is it leaking while running? Suppose having some kitchen towel around it when disconnecting might do the job, it's not ideal but will save any spills.

I also read that you should retighten the screws on the CFC as a couple of people have had the pipes pop off when cooling

Put mine together this morning. Just some added addendums to the step-by-step instructions:

Assembling Discharge Pipe: Attach the hose clamp/jubilee clip before inserting the pipe into the silicone tube.

Assembling The Boiler #4: The best way to insert the bottom perforated plate is to slide it in vertically and rotate it at the bottom of the inner basket. Watch the silicone seal does not come off the plate.

First brew on the Grainfather today, the Apollo IPA from HBC.

Ended up with a 7 hour brew day ??? due to a couple of mishaps, mainly a blown extension lead and the wort chiller.

Really not happy with the wort chiller, I'm not sure how many grams of hops were added but the pump just couldn't cope. It took well over an hour and a half to cool everything down. Maybe I'm doing something wrong.

Other than that everything else was great, the urn was incredible too, worth every penny it took 25 mins or so to get to temp and maintained it for the whole half hour I sparged.

I had a pre boil efficiency of 98%, astounded. expected OG was 1.061 ended up with 1.064.

Tried to get a photo of the wort going in to the fermenter as it was crystal clear, this is the best I could do

(https://dl.dropboxusercontent.com/u/24502376/20150516_175714.jpg)

had a taste and I think this is going to be very nice!

I feel a system like this you have to bag the hops. There's no way it should take that long to chill. Vermelho and i cooled a 21L batch to pitch temp with an immersion chiller in like 10 mins the last brew day. A counterflow should be as capable.

I'll be using hop bags during the boil tomorrow, hopefully that'll make a difference.

I used the GF calculator on the site to work it out, mash volume was 19.16L and the sparge was 13.48L, this was for 5.8KG of grain.

I think the wort might of been a little cooler than I wanted, I stupidly pitched so now I'm praying that theres some sort of activity tomorrow  :-[

I did my first gf brew yesterday. I used hop bags and the chiller worked like a dream.

One word of caution, when assembling, I over-tightened the jubalee clip at the outlet of the pump and managed to tear through the rubber connection. I noticed a leak while doing a first clean, I managed to fix it using a small cable tie. Anyway, don't over tighten it.
Title: Re: Grainfather

Lets start a list of recommended spare parts to have available at short notice (After all NZ is a loooong way away)

I think the pump connections may be the weakest part of the design.

Please add to this list:

1. The silicon rubber pump connectors and cable ties

I plugged out the therm and plugged it in again and it hit the 'HH' ok then, sometimes it would back down to 99 and then start beeping when it hi 'hh'. thats a wee bit annoying but not a big deal cus it was boiling the whole time!

Right! what a day! great machine!

Brewed a pale ale (4kg of grain, .25 carapils and .25 crystal 80 with magnum for bittering and citra and amarillo for the the rest.)

First off, I used the calculations given on the instructions and they are not right. It told me that given 4.5kg of grain, i needed 16.35 for mash and 12.5 for sparge. This gave me 24 litres pre-boil so i'm missing 4l somewhere....

here's the way i sorted the tap fitting...

(http://i.imgur.com/Fofhyv6.jpg?2)

It took 25 minutes to get to mash (67 celcius)

(http://i.imgur.com/CFO8LB5.jpg?1)

The pump chugged a lot here. I thought i had a stuck sparge pretty much straight away but it came round in the end. Just a little slow i guess with strange temp fluctuations but thats my fault for panicking and ramping up the temp every time it dropped. It did look lovely in the end though and stayed +1/-1 on 67 when i got it right.

(http://i.imgur.com/gn6K3E7.jpg?1)

The sparge process takes a while but i started ramping up the temp and just as I finished sparging it was ready to boil which was cool, though it took half an hour.

(http://i.imgur.com/rJx0IPX.jpg?1) (had a 'wee' spill too :) )

The grain cake had a really fine level of grain on top which shows how effective the recirculation is.

(http://i.imgur.com/9qndNft.jpg?1)

Boiling was vigorous, but steady. I ended up losing three litres over an hour. I forgot to add the whirlfloc, but i'm not too bothered cus the recirculation seemed to be really effective, and there barley any trub after the boil, which was great!

(http://i.imgur.com/fMtNMYy.jpg?1)

Overall i'm delighted. I got a 86.92% efficiency but thats with pre-crushed so I know it can do better. I think i read somewhere they correction their calcualtion online which i must get a look at.

Still though, 19l aint bad! :)

cleaning is easy too!

Lets start a list of recommended spare parts to have available at short notice (After all NZ is a loooong way away)

I think the pump connections may be the weakest part of the design.

Please add to this list:

1. The silicon rubber pump connectors and cable ties
2. Rubber Seals that go around the grain basket plates.
3. Glass Lid - I know Im going to drop mine.

Thats something worth adding to the list alright, the neef to make a more suitable part that will stay on better.  It can fall off easily enough and looks very cheap against such a well built system.

Did my first brew on it today using the mash kit supplied by Get'erbrewed FOC - thanks lads!!!  (Hoppy American Pale Ale)
Overall I am delighted with my purchase, its a very well built product and easy to use.

Would I change anything on it?
Yes - I'd attach some form of handle to the glass lid as i feel Im going to drop it sooner than later.

When chilling, a way of monitoring the temperature of the wort out hose would be valuable.  I made the mistake of watching the temperature on the STC-200 instead of feeling the wort out hose to see how cold it was.  I dont want to feel how cold it is going into the FV, I want to know the exact temperature.

I would like to have my water sparging directly (from above the grainbasket) from vessel to vessel rather than filling a jug and pouring into the grainbasket.  I'll look into making some kind of stand.

When cleaning, the Chiller needs to be attached and taken off twice.  The blue and red hose can get in the way here as they are not needed for this part of the process.  Just an idea but I might look into adding quick disconnects here to remoce those two hoses when not needed.

I used nylon hop boiling bags and had no issues with a blocked hop filter.

Heres a few pictures.

It's not a brass cap, it's a twist top for a small bottle (I would guess minibar spirit bottle size). Alpac probably do a bag of 100 of them for a euro.

Well the first brew on the GF went well.

It was a big grain bill 6.5 kg plus 0.5 kg of oat hulls.
So that was like 22.5 litres for the mash in.

Also it was mashed at 70C!

A few notes:

The gf really needs an insulating jacket as on the 500 watt mash setting it was only just keeping at 70C

I used a hop sock and there was no problem with the pumped cooling and the puming out.

A note about calibration.

After the brew I checked the STC-200 against a certified digital thermometer and it was with 0.2 C from 30 all the way to 95C

Also checked the embossed water scales and they were spot on at 20 litres.

I will probably make a false botton out of perforated SS as I dont like the little hop strainer!

Also for Irish outdoor use it needs a lid that stands proud of the boiler (so allowin a good boil off) but keeps the rain out!

All in all I am very impressed. Next is to insulate it and do some step mashes.

Been doing some insulation:

So far its 3 layers of B&Q "behind the radiator" insulation. This is 2 mm thick flexible polystyrene with a thick layer of Aluminium foil (well thick by kitchen standards).

There are 3 layers. Outside layer is nice and shinny but I might be able to improve on it!

It has to affect cooloing naturally!

If you think of the time to get to strike temp, mash, raise to boil and finally boi  you are looking at 3 to 4 hours of heat loss.

Rate of heat loss is proportinal to temperature so the higher the temp the greater the heat loss
So at the boil we have a hugh heat loss per minute.

However as we cool the rate of heat loss also drops (this can be thought of as "cooling loss")

If we use a counter flow chiller then its just that the bulk of the wort stays just that little bit hotter!

Cooling typically takes 30 to 40 minutes and if there is a slight increase in time then I don't think it matters much.

I'm not getting anything like the efficiency others are getting. I'm getting something like 65-75% mash efficiency. I did this brew (https://goo.gl/nxBQur) yesterday. Getting 27.5 Litres of 1.050 pre-boil from 4Kg Pale Ale, 2Kg Vienna, 1Kg Rye, 200g Dark Crystal, 50g Special K. The Rye was pre-crushed. I crushed the rest.

I think it might be a combination of a few things
1) my grain mill is PITA and some of the grain might not be getting crushed but there isn't that much and it can't be the entire problem
2) my mash ph might be too high (need a decent ph meter)
3) might try sparging up to 30 Litre mark to drag that bit more out

Anything else that could be causing poor efficiency?

STC200 connection to  STC1000+ connection
1 -> 5
2 -> 6
4 -> 3
5 -> 4
6 -> 1
7 -> 2

There's a couple of pieces that you need to swap in and out at various times in the brew like the grain tube handle or the 2 caps for the centre pipe. Find places for those where you'll always find them and put them back there as soon as you are finished with them.

Give everything a quick trial run where you're placing the GF like a run of the CF chiller to make sure all the hoses fit and you're comfortable with the set up.

Yep. The standard BS profile leads to oversparging. I only do the water volumes from the manual

I got the Graincoat for Christmas. Put it on today. It was very tight. Velcro didn't make it all the way through. However it seems to stay and felt pretty good on it. Would love to know how much of a diff it'll make.  Going to see how it performs for a brew in the next few days

Would love to know what you thought of it as was thinking about it myself, is it designed to be put on once and left on or could you take it off easily enough say when you want to use the wort chiller to help cool down faster?

You can take it off BUT you're not supposed to recirc the wort back in. Its supposed to go directly to the FV

Just got a Grainfather and made the first brew - pleased so far. But a question for the experienced brewers: the Grainfather instructions go for a stepped mashing sequence ( no times given ). Is this necessary peculiarly for the Grainfather system or are they being pedantic?
Title: Re: Grainfather
Post by: molc on January 11, 2016, 05:37:19 PM
Up to yourself. Depending on the style you may want to do it, but there's no need for a lot of styles. I don't think there's anything particular to a grainfather to influence the decision.

Personally I do a mash out, simply as it costs no additional time and makes the sparging a little easier.
Title: Re: Grainfather
Post by: Leann ull on January 11, 2016, 06:53:19 PM
The idea of stepped mashes comes into its own where grains were historically not fully modified, and benefits say for example if you were brewing a lager with floor malted bohemian pilsner malt.
For somebody starting out all you need to worry about at this stage for ales is your temp at 67 for an hour and mashing out at 75 for additional 10 mins, and more hot water at same temp to sparge with not boiling! 
Get a few of those under your belt and you will be flying and will be doing 35 54 64 67 75!
Title: Re: Grainfather
Post by: Pheeel on January 11, 2016, 06:57:25 PM
They're def not saying you need to do it. Its primarly a guide to show you what the button is to be set at (normal or mash). I do a mash out as its dead simple with the GF then a sparge. Works great!!

Title: Re: Grainfather
Post by: Pheeel on March 07, 2016, 03:48:42 PM
Might be pushing it. Could you scale it down to a 19L batch? Be a bugger to stir so you might want to try underletting by dropping the grain basket slowly into the water. Not tried it myself but apparently it avoids dough balls

No problem at all. I did six brews with the old hop filter and it was fine. Did a couple a month back with the new filter and it did seem to be more efficient at capturing the hops.

I did a 9.2KG batch last week and it was just at the brim! the recirculation arm was having trouble as it was right in the thick of it, hard to stir and sparging took the guts of an hour (needed an extra hand to lift it!) - I would recommend scaling it down if ya can!!!

I did it recently with an 11.75kg grain bill.
5.875kg mashed as normal, no mashout, sparge back upto preboil.
Add in 2nd 5.875kg to existing wort, mash again then mashout this time.
Sparge back up to preboil vol.
Boil.

I have exact steps and gravity reading written down if anyone wants them.

Yea the ease of set up etc is really why I'm interested. I can't have my gear set up permanently and dragging everything outside,  setting up extension leads, etc takes a good hour every brew day. It'll be a while before I make a purchase but I think I might bite the bullet!

Grainfather is an excellent bit of kit. I used to brew on gas. It was a huge pain, too expensive, kept overshooting my mash temp and too many things to clean. With the GF i can put it on after dinner to get to mash temp, watch a film with the kids, start the mash half way through the film, put the kids to be and be done with loads of time to enjoy my previous brew. Clean up is a joy (as much as clean up can be).

Post by: BrewDorg on March 25, 2016, 01:43:11 PM
Not sure if this is what ye're asking, but I know if I want to change my mash & sparge amounts in my mash profiles, I need to increase/decrease the grain/water ratio value. Double click your mash step in BS and you'll see it. Let me know if that's what you mean!
Title: Re: Grainfather
Post by: DEMPSEY on March 25, 2016, 04:46:03 PM
tried that but the issue with Grainfather is you have a grain to liter ratio all right but then you add a fixed amount extra of 3.5 Liters :(

Title: Re: Grainfather
Post by: Hefeman on March 25, 2016, 09:24:15 PM
I have only done a few brews on mine and had a couple of disasters, stuck sparge (milled too fine), blocked pump resulted in aborting my first two attempts. On third attempt I milled on wider setting and used hop bag for all hop additions and the brew went very well though low efficiency. What's the verdict on using boil bags for hops? Do people hang them off the side? I can't understand how GF are claiming this is not necessary. Also their hop spider seems to be too coarse for pellets at 800 microns.
Title: Re: Grainfather

I had brewed a dipa with a mix of leaf and pellets with about 250g of hops. Nothing came out of the counterflow chiller until i moved some of the leaf off the filter so that the pump could do its work. 2 second fix and it was grand after that.
I bought a hop spider in the recent group buy as i find lifting the GF and emptying it with a load of wet hops can be a ton weight. I personally haven't bothered with hop bags a year+
Title: Re: Grainfather
Post by: fishjam45 (Colin) on March 25, 2016, 10:36:00 PM
Pellets for me in a hop bag everytime, never any issues with pump filter.

I once had a very slow sparge but that was due to grain crush too fine.

Title: Re: Grainfather

Does anyone find that the odd bit of grain is ending up in the boil? Did a brew today and noticed some grain made its way in, worried about tannins now!

It didn't escape down the side when I was mashing in as I use a funnel, nothing went down the overflow pipe during mashing either.

I think the plate at the bottom is letting grain through, not because of the rubber seal but because of the size of the holes and possibly my crush.

I noticed some Bruameister owners had the same trouble with grain in the boil, they now come with an extra mesh filter to cover the plate. Might give this a shot for the next brew.

Jasus.... Glad I came across this thread. I've had the Grainfather for about 10 months now and felt like a loner. I find beersmith complex at the best of times so I was glad to see that there was an app for this wee beauty. Funny thing is the Grainfather App puts me about 2 litres short of sparge water in comparison to the Grainfather manuals calculation. It's a great piece if kit that after about 6 brews I'm getting the hang of. Whirlpool was never mentioned before and when I did it on met latest batch I was able to extract more into the fermenter as the clogging became less of an issue. I do believe my brews are getting more consistent and the final results are worth the outlay. I have the old filter.

Has anyone set this on a plant stand with wheels? I heard that is the dogs for ease of movement.

Guys, do you know if the new pump filter is included in the MK2 version or is this optional? I received mine last week, had the first Grainfather brew day today and I have to say I'm everything but impressed. I took me 10 hours until I could  pitch the yeast mainly because of the massive problems with the pump filter ( the old one ) which was completely blocked by the pellets, also I had to clean the valve, remove and clean spring inside like four times. The wort was only dripping very slowly so the coolig wasnt effective at all... For now I hate that thing :)

I used about 90g of pellets in total, graifather support says this shouldn't be an issue. Next time I should use the hop bags I guess

The dealer told me this is the newest version but has the old pump filter?

P.S The efficiency was still 7 points higher than expected and the clarity wasn't bad either.

I did a handful of brews with mine and the first couple were disasters (initially milling too fine, even had terrible trouble with the HBC kit that came free with it which I ended up dumping at 2am!), next one I ended up chilling with my old immersion chiller after blocked pump, again at 2am.
On my last two brews I was ultra careful, first I used hop bags hanging from the side clips and removed them prior to
chilling. This worked well and got good flow out to the FV. This was an SNPA clone so not exactly a stress test.

On my last one after considering that others say they don't use hop bags I used about 140g of pellet hops with a 6.5kg grain bill. All went fine until chill time, I turned on the pump but got no flow. Then I turned off the pump,  removed the  recirculation arm and with my mouth blew into the outlet pipe resulting in bubbles passing up through the wort (a trick I read on this forum). When I turned on the pump I then had an acceptable flow (though slower than I would like).

Note that I tried a whirlpool before chilling as recommended by GF but this seemed to do nothing as I had a flat layer of trub at the bottom and a concentration of caked hops around the pump filter.

Hope this helps, stick with it I feel your pain!

BTW Can you confirm your filter is inline with the pump outlet, not perpendicular? I bought mine before Christmas and got the new filter and grain stopper.

Did the Liffey Brew day and all went well except for the cooling stage. 60 grams of hops total but the flow return going back to the grainfather slowed to a trickle. I stopped it and whirlpooled the wort and started again but after awhile it slowed again. It eventually got to around 34 C but the slow rate had the trickle at 15 C so I transferred to the fermenter. Too slow for that part of the time. Only other issue I had was getting to full boil but that was because we were out in the cold back yard,will need a jacket for outdoor :)

Just looked at the grainfather youtube clip and he only waits to cool the wort temp to 20 C or so and transfer straight to the fermenter. Do any of you return the wort to the grainfather and so chill all the wort in place before you transfer. :-\
Title: Re: Grainfather
Post by: Simon_ on April 03, 2016, 11:03:15 PM
I only do that if want to drop a little for a hop stand. Otherwise I just go straight into the fermenter. Chilling is most efficient when the temp difference is greatest. Nothing is gained by recirculating.

This is an email I received last week on the blocked filter

Hi Ruairi,

Sorry to hear of the issues that you are having the problem with hops in the Grainfather. Are you stirring the wort into a whirlpool prior to starting the pump? This helps create a filter layer over the pump filter. There is a good explanation of this technique in the Weekly Mash section of our website.

We are hoping to have the hop spider back in stock by the end of April

Best Regards,
David

@ hefeman - yes, the filter is inline with the pump outlet.

@ all. thanks for all the answers. So, I guess I have to buy a hop spider a a new pump filter :)  Now, I have to say I am seriously disappointed with the GF. I did everything as in the GF video and encountered massive issues with the pump, filter and valves, my brew day was a 10h brewing disaster .

I mean I paid 850 euros for that thing that was supposed to make my brewing faster, less work, and more pleasant. Instead it ruined my Sunday and the chances of wort infection are quite high after all what I had to do in order to get the pump and valves to work again. Now I have to buy a hop spider and a new pump filter and pray to God every time I brew that the pump doesn't get blocked.

I also got the GF Insulation coat, and guess what? Its 2 cm to short, one end of the velcro fastener doesn't reach the other so impossible to wrap the coat around the vessel properly.

The only thing that really works as supposed is the sparge water heater :(   I should have saved more money and go for the Braumeister.

I bought a hop spider in the recent group buy...a worthy investment! Did a brew last Monday, 125grams in total used, chilled and in to the fermenter in roughly 20mins! Recipe called for a hop stand, I just recirculated the wort through the spider when sanitising the chiller to get the most out of the hops. I have the old hop filter so no need to buy a new one once you have the spider.

Don't worry, I remember my first brew day with the Grainfather was a nightmare...I now have my brew day down to between 4 and a half to 5 hours. I'm exceeding numbers and making stress free beer...honestly you just need more brew time on it, it really is a great piece of kit once you know the ins and outs and get your flow down!

That isn't necessary but I think it is recommended to recirculate for a few mins just to sterilise the recirculation arm.

Aah haa that's were I went wrong on my first outing so. My old system has a counterflow and a chugger pump and I would pump the fook out of the wort and back to the boil kettle thus cooling all before going on to the fermenter. Need retraining I doe's  ;D

I've always been a fan of recirculating back to the BK, as you cool the whole body of wort at the same time, which retains more of the hop aromas from what I understand. I do it with a plate chiller and get from 100-17 in 15 minutes.

So,
1 finish the boil,
2 switch off the pump,
3 stir good and hard for a minute,
4 let the wort stop spinning and let it settle,
5 switch on the pump to run hot wort through the counterflow and back to the grainfather for 2 minutes,
6 connect the cold water to the counterflow and begin cooling wort.
7 confirm cool wort temp as it return's to the grainfather and when it is 20 C redirect it to the fermenter.
Title: Re: Grainfather
Post by: Simon_ on April 04, 2016, 10:16:38 AM
Here's how I do it

1 10-15 minutes before end of boil, connect the wort chiller and turn on the pump, recirculating into GF to sterilise the chiller
2 connect the cold water to the counterflow
3 finish the boil
4 stir good and hard for a minute,
5 turn on cold water, move the wort-out tube to the fermenter (turn off the pump briefly if you can't do this without spilling)
6 confirm cool wort temp as you take a gravity reading. It should be around 20c depending on your water temp. If it's too high increase the water flow
7 when it's finished transferring I put it in the ferm chamber and connect a temp probe. When it's at my pitching temperature I pitch

I find that if I connect the chiller before the end of the boil it kills the boil and it takes a couple of minutes to get it back, so I've just been connecting it as soon as the boil is over and recirculating it for 5 minutes before chilling, this has been working well for me.
Title: Re: Grainfather
Post by: Simon_ on April 04, 2016, 10:32:46 AM
If I'm making a lager and I want it much colder than you'd get from the tap water I connect in a pre-chiller. This is copper chiller in a bucket with ice water connected between the tap water and the CF chiller.

Recirculating back into the GF is fine for sterilising the chiller but it's pointless for getting down to pitching temp any quicker. The easy part is getting it to drop from the hottest temp. The harder part is to get it to drop the last few degrees. The best way to get it down the last couple of degrees is to increase the water flow.

Thanks guys.

I was trying to cool the wort down by recirculating back into the GF which obviously was a bad idea and contributed massively to the total brewing session time.  I'm going to order the new pump filter, take your advice as for the brewing steps and see how it goes then.

Two things that I'm impressed with - the clarity is amazing and the OG was much higher than expected.

304 Stainless Steel

Stainless steel provides an attractive, clean finish with low maintenance cost
304 stainless steel has a high resistance to rust. It withstands corrosion from most oxidizing acids and is often used for kitchen and food applications. However, it is susceptible to corrosion from chloride solutions (notably saline environments with high amounts of sodium chloride). Chloride ions can create localized areas of corrosion, called "pitting," which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.

Isn't OXI a sodium chloride solution?

Quick update - after the new pump filter arrived my next brew day was close to perfect. I used leaf hops, around 150g in total, no hop spider or bags were used. GF performed great, no further issues with the filter, valves etc. I've recilculated the  wort for 2-3 minutes into GF and transfred then straight into the fermentor. Wort temperature was 20C during transfer. The counterflow chiller is fantastic.  Again, OG much higher than expected, great clarity. I will buy the hop spider though - just for peace of mind :)

Post by: Archsnapper on April 13, 2016, 05:10:47 PM
I bought the hop spider for the peace of mind, as well. It's grand with a "normal" amount of hops, but I made an amber brew the other day which required quite a lot, and it was rather full. I ended up twisting a piece of clothes hanger to allow me to let the spider deeper into the boil and stirring it's contents for some time.
Such is life - nothing's perfect!

So I just used some Velcro backing to fasten it together. I seem to take about 30 mins in average to reach boil but it really depends on the size of the grain bill as well as what's in it, wheat, Barley, malt etc.

Heres a small video review of the new GF Control Box:


GRAINFATHER CONNECT BLUETOOTH CONTROLLER REVIEW PART ONE

https://youtu.be/6dY2QiqwpE4

I'm liking the fact that you can use your old control box for something else now too.  I expect to see full "here's what I did with my old one" posts  ;D

This does look like a pretty sweet update in fairness though and he doesnt even get into using the app yet either.

I watched the video for the Bluetooth controller. If I actually used my brew shed for brewing in then it would be useful to set a strike time. I don't do step mashes that often and honestly it's really very little hassle to set an alarm and change it. I'm just not sure it's worth it for me...

I had a look at the controller video as well. Yer man is clearly very taken with it. I liked the look of the PID temp control. Although mind you the temp control isn't too bad as is. Hard to know if it's worth the 120 yoyos though.

Put on a brew yesterday using hop bags for all additions (pellets) and the whole process was much smoother and much easier to clean in the end. Cut my brew time down to just over four hours.
Title: Re: Grainfather
Post by: mick02 on November 22, 2016, 01:55:33 PM
Had a disaster brewday the other day.

Did a double brew on Sunday, the first batch was going grand until I was pumping into the fermenter and forgot to close the tap. Lost about 4 litres to the floor. That wasn't even the worst part of the day.

I've got a Grainfather and I invested in the new and improved pump filter (the T shaped one)

When I was doing my hop stand I decided to stir the wort to create a whirlpool. When I was stirring I heard the filter come off (I heard scratching from the bottom of the vessel). I tested the pump and sure enough it got blocked. I had used a mixture of whole leaf and pellet and the whole thing was fully blocked. I decided to pour the wort into a sanitised bucket and try to clear the blockage. While pouring the wort into the bucket, the support for the GF slipped and 25 litres of wort went pouring onto the patio. Broke my heart.

This is not the first time the filter has come off while stirring although the last time it happened I did managed to knock it with my mash paddle.

To top it all off I dropped and smashed my thermometer when putting all my equipment away.

Just some advice for anyone using the new filter, be careful as it can come dislodged during stirring.

I got mine from the Homebrew Company. Works grand, although with a decent quantity of hops I have rigged up a wire hook to allow the spider to sink more into the boiling wort - and I stir it now and again throughout the boil.

I bought a Grainbrother the other week from THBC. They sent me the new controller. I used it to brew a pilsner with a step mash. Lovely!

One thing I noticed is that the pump on my original GF was a LOAD slower than the pump on my GB. I checked and it's the same model. I think I need to clean out the pump on the GF as it's probably got some gunk in there. Has anyone attempted this? Any guidance? I don't want to balls it up!

I haven't opened up my pump to clean it so can't comment. I did have a pretty serious blockage a few brews back and used a pump for an air matress to blow are through the recirculation arm back into the kettle. It cleared the blockage and I did notice a performance improvement. Your mileage may vary though!

I use pbw after most cleans.
The GF cleaner gets used now and again for a proper clean when I leave the water pumping through for over a half hour. The pbw works at a lower temp so it makes cleanup quicker.

One of the designers (guy who's in all the GF youtube videos) from iMake said PBW was fine on a Reddit AMA (https://www.reddit.com/r/IAmA/comments/2x0sxs/i_am_imker_swanepoel_industrial_designer_for_the/covw8mq/)

Post by: mick02 on December 05, 2016, 02:26:24 PM
I've also found a bug on the new GF app if you're brewing using an imported recipe from BeerSmith.

I found that if the boil is more than 60 minutes (90 in my case yesterday) the app disregards any information before the 60 minute mark (i.e. the 90 minute hop addition) and starts to countdown from 60 minutes.

If you pause the timer to try and let the boil catch up with the app you lose all info of the session off the app. Kinda a nuisance as I was left scrambling to calculate times/additions on the fly.

I've flagged it with GF though, hopefully they will be able to squash the bug.
Title: Re: Grainfather
Post by: Níall on December 19, 2016, 05:15:08 PM
Hi all,

I did my first Grainfather brew at the weekend and it all went very smoothly until it came to chilling time. After attaching the chiller and recirculating for a few moments the pump stopped flowing and after several attempts to get it moving I had to abandon the brew and proceeded to jug out the wort to empty the boiler, the grain particles were very visible in the sample:

(https://farm1.staticflickr.com/720/30936871833_1cacb22a9f_m.jpg)

I did notice when the boil started that there seemed to be a lot of grain particles - certainly a lot more than I normally get. When I was emptying the boiler contents with a plastic jug I put a sieve in the sink and poured the wort through it to see how much was in the boil:

(https://farm1.staticflickr.com/763/30936871783_9d2c00bf91_m.jpg)

I took the pump filter off and there was hardly any grain inside so I'm guessing the grain passed through the filter. I also removed the ball lock and spring and there were no blockages there. After the boiler was emptied I blew down the chiller's wort output pipe and this did force out a little grain and a single hop flower so it seems as though the blockage was indeed in the chiller and not the pump. In fact I ran the pump without the recirculating arm or chiller attached and the liquid flow coming out was fine.

I'm not sure if this is related to grain crush, I used a mashkit that I got from HBC for this brew, maybe the grain crush was too fine for the GF. I do have a Crankandstein 2 roller mill that I can use to crush whole grains so would be interested to know what setting to use. There was only about 50g of hops in the brew, both in hop bags so I would be surprised if they caused an issue.

Despite having to abandon the brew I'm encouraged by the ease of use of the GF, up to the chilling stage it was a very relaxed session compared to my normal brewday with 3 vessels, pump etc.

I'm curious to know if you've experienced similar issues and if you know what might cause them!

I don't think it was the mash kit from HBC. I've brewed lots of these kits from HBC and have never had the problem you were having. There must have been some issues with the pump filter if a full hop flower was stuck inside. The perforations on the filter are so small that there is no way a hop cone could pass through it.

I'd concentrate my efforts at the filter.
Title: Re: Grainfather
Post by: Níall on December 19, 2016, 05:30:16 PM
Cheers Mick. Yeah, I was a bit puzzled how the hop flower made it that far as the pump filter seemed well secured and intact.

In terms of the grain particles getting into the boil is this something you've experienced? I did notice when the mash started that a lot of foam was produced and perhaps some grain went down the overflow, it was hard to see it clearly due to the foaming.
Title: Re: Grainfather
Post by: fishjam45 (Colin) on December 19, 2016, 05:32:07 PM
I've ordered a small mesh sink strainer to sit over the overflow pipe inlet, that should stop any grain getting through
Title: Re: Grainfather
Post by: Dunkel on December 20, 2016, 12:14:10 PM
I had similar problems, and found the blockage was occurring at the spring-loaded ball bearing just below the flow valve on the wort pipe after the pump. I took the ball bearing and spring out, and had no further problems.
Title: Re: Grainfather
Post by: Níall on December 20, 2016, 12:23:42 PM
That did cross my mind at the time, as it happens the spring and ball valve on mine were clear.

I'm wondering if something else may have caused this - I attached the chiller with a few minutes left and dropped the wort output hose into the boiling wort. With the lid on and the chiller sitting above it the boil rose very quickly and reached the lid before I killed the heat. I wonder if the lone hop leaf I found in the chiller could have got pushed up this hose from the vigorous boil as I can't see how it would have got through the pump filter. In any case I think I'll wait until the boil has finished next time before I attach the chiller.
Title: Re: Grainfather
Post by: DEMPSEY on December 20, 2016, 12:46:37 PM
When I used a different system I had a counterflow chiller with a 10mm pipe. I piece of hop pellet had not dissolved and so got sucked into the pipe and even my mighty chugger pump could not shift it so a bit of hop can cause a major blockage.
Title: Re: Grainfather
Post by: Pheeel on December 20, 2016, 12:46:57 PM
I don't attach the chiller until the boil is finished and record for 2 mins to sterilize. Not sure why you have so much crap getting through. It shouldn't be!!

I'd put this down to a freak occurrence. As I said, I've done about 60 sessions on my Grainfather and the only issues I've had were knocking off the filter when stirring the wort. Other than that I've never had any real problems.

If it happens again I reckon you're doing something wrong or something isn't hooked up right but I'd chalk this one down to experience.

I brewed again over Christmas and this time I had no issues with the pump. I did however include almost 20% porridge oats in the grist and went with a single infusion mash which made for a stuck sparge, much lifting of the top plate, stirring of the mash and a little swearing. I did wonder whether a Beta Glucan rest might be worthwhile with such a high percentage of oats and I got my answer, so that's a lesson learned. Ultimately the wort got into the fermenter so we'll see how this turns out.

Cold sparging does taking longer to get to a boil on an individual beer but I have a Grainbrother too so I'm trying to ramp up to boil doesn't matter too much as I need to wait for the mash for the other one anyway. Also I'm probably kegging beer at the same time too so need to clean FVs and kegs and keg beers so any spare time helps!!

Do you first do a Mash out temp. Gotta stop them enzymes in their tracks. ???

Are you mashing out?, The reason you mash out at 74-76 is as Mr Dempsey says is to kill enzyme activity and preserve your fermentable sugar profile, you will also loose a couple of percentage points from sugars still on the husk that you haven't rinsed off at higher temp but tbh that's probably marginal.

I have had a look at this now and I see you have found the secret method to brewing a NEIPA. The cold water sparge will bring more break material over making the final beer more cloudy,it may also help with head retention so lots of suds :).
Title: Re: Grainfather
Post by: Pheeel on January 06, 2017, 02:33:04 PM
Sometimes mash out, sometimes don't. I often jack the GF up to boil when sparging so that should kill any activity 😀

Post by: brian_c on January 06, 2017, 02:47:49 PM
Just to be certain, by mashing out you mean when you jack the temp up to 75 after your 60min mash. Then leave it for 15mins approx before raising the basket.

I'm working on a grainfather ep of  ICB show and don't want any stupid mistakes.

Post by: BrewDorg on January 06, 2017, 03:33:44 PM
Yep that's exactly it. The higher temperature stops the enzymes converting the sugar any further and 'locks in' the sugar content achieved at that point.

Title: Re: Grainfather
Post by: DEMPSEY on January 06, 2017, 11:24:43 PM
So as not so confused matters but once you add water to grainfather you begin the wonderful magic of washing out the starch sugars and the enzymes and they are now in the water so by leaving the wort at a temp below 78C will level the enzymes still active. When the mash is complete you can raise the mash temp to mash out then you have sealed the fate of the enzymes. You can then take your time cold sparking if you want  but it will take longer to get to boil.

Dempsey. When you say cold sparging, could you just use water direct from the tap to sparge?

To work a brew around family etc. I usually mash at night and boil in the morning so getting to the boil isn't an issue.

If you are on a well you don't need to worry about chlorine and if the ph of your tap water is below 6 you don't have to treat your sparge water ( read this somewhere so open to correction on this )
Title: Re: Grainfather
Post by: DEMPSEY on January 08, 2017, 12:21:19 PM
PH is not much of an issue as the main reason you want a PH around 5.2/ 5.4 is in the mashing period to help the enzymes work without hurting them. your last sparge running's should be in around 6.0 PH or you might be washing out some harsh stuff.

Those tubes are probably under stress as in if you chopped down one side it would ping out.
thinking about it, it may be better on a flat surface so you could see where or if it was out?
You may be able to get it tapped out at a Panel beaters or eng works?
Whatever you decide do it slowly and roll or insert mesh after each alteration.

Started a brew today (Habenero IPA), had grain crushed , mash water heated and suddenly realised my overflow pipe was missing. Hopefully it turns up. Luckily I'd a bit of copper pipe in my shed so some hacksawing and filing a had a sort of replacement. Didn't grip like the real one so had to cut it exactly to the length of my grain bill. In the end went too short and had to pull about 700 grams from a 6kg grain bill. Almost met my gravity though .

Thinking of buying one of these and I have a question.

I currently BIAB in a 33 litre pot - not so far off Grainfather capacity when you knock some capacity off for the lid etc.

The standard mash water formula for the GF is Grain Weight x 2.7 + 3.5 so, for a 4.5kg batch this would be 15.65 litres of strike water. I would normally use 26 litres with a batch that size then dunk sparge with about 5 litres.

So - why wouldn't I continue doing this in the Grainfather, obviously adjusting for capacity?
Title: Re: Grainfather
Post by: Leann ull on January 21, 2017, 06:52:42 PM
Grain to water ratio in recircs is anywhere between 3-5l per kilo, 7 for biab, I've done 3 and 6 and there is marginal difference in total efficiency (more efficient high side) or on taste.
Title: Re: Grainfather
Post by: DEMPSEY on January 21, 2017, 08:19:49 PM
The grainfather numbers are correct and when you add your sparge you will end up with 28 liters before boil.

Post by: darren996 on January 25, 2017, 11:47:03 AM
Grainfather users, do you get any flour back into the kettle after mash in ? i.e. any flour seep through the bottom filter plate and into the wort.

Thanks

Post by: fishjam45 (Colin) on January 25, 2017, 12:02:47 PM
I've found it sitting on top of grain bed after sparging alright.


I have been wondering if the flour has been clogging my group buy hop spider, anybody else find this?
When cleaning up after brewing the small holes appear to be blocked by flour - not good if your using a lot of hops!! When you lift the spider the liquid is only trickling out of it.

Anyone else have this issue?

Don't have a grainfather, but I find my hop spider drains very slowly after a boil - most of the holes get fairly blocked with protein break and goop. Doesn't seem t effect the hoppiness of my beers though, so doesn't bother me.

Would like to give it a caustic wash or something every few batches to get all the crud off though - it's changing a funny colour over time.

If you export a Beersmith recipe to beerxml and import it to the grain father it will bring across the mash profile but it ignores the beersmith mash water and sparge water calculations and substitutes it's own based on their calculations.

Got it from the Homebrew Company so its coming with a mash kit (American Wit) or do I go ahead with my planned Triple Karmeliet clone which has stepped mashing. My efficiency is around 70-72% at present as I don't crush my own grains, will there be a big jump in efficiency with the Grainfather?

What about the hop filter on the pump is this ok on its own or would you need a spider or hop bags? Especially doing a really hoppy beer, is clogging a problem. I have a spider but for some reason prefer throwing them in loose.

Ha, so it's that good? I do have a spider so might just have to use it and maybe recirculate through it to get everything out of the hops. I've just done a Pliny the elder clone so don't reckon it would handle all those hops.

Ha, so it's that good? I do have a spider so might just have to use it and maybe recirculate through it to get everything out of the hops. I've just done a Pliny the elder clone so don't reckon it would handle all those hops.
The filter is actually good but the design is terrible. In the last 3 brews I've knocked the filter off twice just by stirring the wort and in the last brew the rubber cap at the end disappeared rendering the filter effectively useless! I'm going back to the old filter. I've done a Pliny clone on the Grainfather before... You're right, it won't handle all those hops.

Thanks Mick, I'll check that out so. I really like using Beersmith so would like to keep using it. I'll do comparisons with water volumes and probably air on the side of caution if they're way out.

What about the hop filter on the pump is this ok on its own or would you need a spider or hop bags? Especially doing a really hoppy beer, is clogging a problem. I have a spider but for some reason prefer throwing them in loose.

As a counterpoint, I've done some 300g hop monsters in it with the included filter and had no bother. Runoff is slow, but it's always slow I find anyway.

Do you use pellet or leaf Molc? I've personally found that the filter copes better with leaf than pellet

Yeah leaf is good for filtering. It's about the only way it's preferable. It's like using rice hulls to prevent a stuck mash. But you can do a little bit of leaf and alot of pellets and it'll filter just fine.
When only using pellets I find if I have to scrape the filter once towards the end of transfer and it'll finish fine.

Got my Grainfather. It's an impressive piece of kit. Cleaned it out last night and am doing a test boil, or trying to at least. Feckin thing won't go above 98 degrees. Really not happy with this at all. It's bubbling away nicely but confirmed temperatures with my Thermapen. Am I doing something wrong here? I boil outside on my balcony but it isn't even cold today. I brewed last Friday in the snow and my Buffalo boiler got a boil no problem. Hope I don't have to bite the bullet and get in insulation jacket, would this help me reach a boil? Hoping to do a brew next weekend but not confident now at all if I can't reach a boil. If I've to transfer over to my Buffalo it defeats the purpose of an all in one system.

Are you on high ground, well above sea level?

The boil temperature can be changed in the app, have a play with the settings.

In Dublin, around 75 meters above sea level and live in a first floor apartment so nothing major. I lost a good 4 litres while on for around 90 minutes so it seems to be boiling but won't go above the 98 degrees. It's pretty frustrating. If I can find that setting should I drop my boil temperature to 98?

Temp is  being measured at the bottom. The top section is boiling but if your doing outside any wind will take lots of heat away. Try it inside as an experiment. If you are going to keep it outside you do need that coat

I brought it inside just to check and it got to 99 degrees and verified with my Thermapen. I have to boil outside so might just have to bite the bullet and get the coat.

Is it super important that it hits 100? I mean you say its bubbling away and you lost 4 liters in 90 mins. Surely that's all you need.

That's what I'm not sure about, I was always under the impression that 100 degrees was boiling point. It was definitely bubbling away nicely and lost a good few litres of water. Is 98 or 99 degrees an acceptable temperature to hit?

The cable connector from my element melted into the bottom of the old controller box. I've bought the new controller but I'll need to replace the connector. Does anyone know are these generally available in hardware stores? Grange Electrical, B&Q, Woodies.
Maplins was suggested to me but I'm hoping to pick one up more local (Dublin 5). 
Also is there a name for the part I'm looking for so that someone in Maplin or a hardware would know what I want?

What you want is a c15/c16 iec connector. The problem with old one is that it was probably a c13/c14 connector which isn't rated for heat use. The c15/c16 connectors have a notch on them to differentiate between them.

Finished my third brew with the Grainfather yesterday and really like it but one major thing is bothering me and it's the water volumes. The volumes yesterday were pretty bad. I use Beersmith for design but use the Grainfather app for water volume. Long story, I was aiming for 25 liters into the fermenter. According to the app my pre boil volume should be 27 litres and I got 29 and there was easily another litre in the bucket I put the grain basket into when I finished sparging. I didn't throw this into the boil as I thought I had loads. Going by Beersmith my pre boil gravity should be 1.054 but was actually 1.061, no problem there. Have efficiency set to 75 so just need to boost that. Anyway I was left with only 24 litres at the end of the boil.

So I'm starting the boil with too much volume and finishing with too little. Really can't understand this. I can boost my initial volumes to yield more at the end of the boil but gravity will suffer or decrease my initial volumes but will be left with even less. Each solution is cancelling out the other. Has anyone come across this?

Used my grain mill on this for the first time too and think it was too fine of a crush as the sparge took well over an hour and the mash was constantly over flowing so I had to monitor it constantly and turn the.pump off every now and then. I set the mill to a credit card thickness but I double crushed them, grain was fairly well milled after this. What's the ideal mill gap setting for the Grainfather, definitely going wider and won't be double crushing them. Efficiency was great but sparge length was rediculous and I think having to turn the pump off every now and then defeats the.purpose.

Post by: Simon_ on April 16, 2018, 04:45:57 PM
You can adjust your Beersmith boil off, grain absorption, and efficiency values to what you are getting.
Sparging should never take that long. When I start sparging the wort is ramping to a boil and I'm normally finished sparging by the time it gets to 90°. Most of the time it flies through but if it's slow because you've a load of wheat or whatever you can scrape the bottom of the grain basket a bit with your paddle to get it running. You've no problem with efficiency so may as well get it done quickly. Sounds like there's no need to double crush your grain. Credit card width is fine.
Title: Re: Grainfather
Post by: aaronm13 on April 16, 2018, 05:35:17 PM
Thanks Simon. The first 2 batches I did the sparge took no more than 20 minutes, these were pre crushed grains. It was my first time using the mill and a lot of the grains didn't look crushed at al which is why I ran them through again. Won't make that mistake again.

Adjusting the boil off and grain absorption is fine but surely this will only increase my original volumes, as it is I'm getting too much back. Really has me baffled.

When you reach the boil do you scale back power or leave it at 100%? I scaled mine back to 90% yesterday.   
Title: Re: Grainfather
Post by: Simon_ on April 16, 2018, 05:57:39 PM
So I think your grain absorption is lower than you've set because your preboil volume is higher than expected. Your boil off is greater than you have set because you've ended with less post boil. Or your dead space value is wrong or a combination? Does that make sense?

All the  grain or nearly all should be cracked after 1 run through the mill. You might just have to play with it to get how you like

Post by: aaronm13 on April 16, 2018, 06:15:32 PM
Think there's a bit of trial and error with it alright. A good excuse to brew more. The grain was like flour in fairness going into the mash, so definitely too fine.
