Title: Polypin
Post by: sub82 on June 28, 2013, 09:30:18 AM
Anyone any experience of these?

Thinking of doing an ale for a party at the end of the summer and a 20L polypin seems, logistically, the best option?

Bag in the box type? marceldesailly  has experience with those ones.

Yeah that's it - looks simple enough?

Just rack into it and prime depending on the quantity of beer.

Yeah, that's it. I believe they work very well.

They do-where are you getting the empties from?!

Not sure yet - do you know of anywhere that sells them?
Think you can buy empty reusable ones for around £10.

No haven't been able to find any local places so was looking at some of the UK online shops.

Ye its all pretty straight forward as you as you might imagine. You do need to bear in mind a couple of things, like how long to condition it ( out of and in the polypin), finings or not and volume of CO2.

And two other points. They do swell up rather alarmingly but you just need to hold your nerve ( or just degas it a little a few days before you intend on dispensing if it gettign very worrying!). I've found priming above the recommended dose works well ( maybe 30-50% more), it'll still be cask like so don't worry about that.
Unless you put it inside a box or something the amount of yeast that drops might put some people, so if that will be an issue fining it a few days prior to putting it in the polypin is usually a good idea.  And obviously if you have a lot of yeast moving it to where you want to serve it needs to be done with enough time for everything to settle and clear.

It's quite satisfying pouring pints from it as it settles in the glass just like  a hand pulled pint! And it'll easily last 10days+. But ideally get it finished ASAP.

I've only ever gotten them from my GFs dad in the UK but I was looking into them before and came across a couple of sies that might be of interest to people.

I got 10 5l itre bags and boxes delivered to dublin for £35

It was about 17 for the boxes but 19 for the postage!

Still they worked out at about €4 each as opposed to a tenner.

The only problem is that the taps and bags are meant to used 1 off! They can be refilled but its a bit of a pain.

Vinotainers that have a tap that just unscres are a lot more easy but are a lot more expensive!

Looks good - will check out the Jims thread.

You can get them here, they are called vinotainers and all the homebrew shops have them. I use a few of them at home and have done a stout in one before and it came out excellent.

Did you carbonate it much? I'd be worried about the vinotainers bursting if they are designed for wine.

They are the same container and are very tough inside. I used a ten litre one for the brew and from what I can see the bag inside is a polypin, no difference, it is heavy tough plastic and not the light stuff.

I carbonated....not sure how much but it worked for a stout, perfectly, it's a while back now and I only used the polypin due to the amount I had left over after kegging or something, not sure now.

Cool thanks for the info. I'll maybe order up one of those and give it a go!

Shane - was on the phone to Hilden earlier, they can supply 20L polypins.

In fact now that I think of it, my cousin gave me one of the polypins it was from Hilden, they got it for a party and it was a vinotainer the same as the ones I already had at home.
Title: Re: Polypin
Post by: sub82 on July 02, 2013, 07:29:19 AM
Sounds good then. Hilden can only do 20L but think that might be a bit much especially considering transportation. Do you think a 10L one would be handy enough to transport via train?

10l is not so large. I'd say you could transport it by train, but it'll need time to settle and you'll need to be prepared to vent it now and again.

Sounds good then - will definitely try it. How much would you need to vent it? Would it stay carbonated?

I did ten litres of stout the time I used mine, I normally use them for cider, I found it conditioned nicely, held condition and did not need to be vented all that often but I primed it on the low side and it was bulk primed, the rest was in pressure barrels. I was surprised at how well it kept the beer in condition and how easy it was to do. The box is also helpful because it gives some extra strength if you don't vent enough.
There is an extensive thread on JBK on using polypins, too much to reproduce here, a lot of them are using them with beer engines.

They're not the same heavy material though, I'd personally be wary of putting beer in those.

That's more like the weight of plastic you should be looking at and is the same bag that is in a vinotainer.

Received it today and brewing the beer tomorrow for it so will keep an update going!

Thanks for all the advice.

Just an update on this!

The polypin sterilising.

2 weeks after priming (40g sugar in 10L). After 48 hours I had to open the tap to reduce the pressure as it was rock solid.

We used a pale ale recipe for this but i think next time we'd use brown ale due to the lack of carbonation.

I've used one of those for wine.  It doesn't collapse properly, I reckon the tap is upside down, but the box is cut the wrong way. Tip it forward when you pour if it starts to suck air back in.

This are good for carbing cider. Good enough for cider good enough for beer.
