I think if you really care about the water chemistry its better to just test you water with the little aquarium kits.  There can be considerable variation and the values they are reporting are only averages which may not be very up to date.  I tend to use my own results for alkalinity and carbonate and take the average values for sulphate, chloride etc.

Amazing, been struggling on this for a while!

Thanks,

Sounds interesting. What sort would you buy?

This a great resource.  Were you able to get specific values for
Calcium
Carbonate
Magnesium

are these listed under a different name or combined into other readings?

Ciaran, I spoke with them a while back and posted their reply and some test results for BT6.

Cheers Andy, yea I decided to just email them directly for the extra detail.  I've updated that thread for BT8 so hopefully that helps someone else.

BT36 is moderatley hard. i got a full report a few weeks ago.  bit of faffing about but they sent it across.

I emailed them asking specifically about elements of concern for brewing - they got back to me the same day. Brilliant service. What does strike me though is that these are annual results - as such I guess they are ball park figures to be used as a starting point, and must change - especially after the downpours of late! I would be interested to know if anyone tests their water more regularly, and what kits are used?
Title: Re: Water Analysis

Yeah I test my water before each brew using the Salifert aquarium kits, one for calcium and one for alkalinity. These are the most important values, you can then make sure the mash pH will be in the right area and adjust the Ca level to where you want it by adding CaCl2 or CaSO4. Both these salifert kits are available on eBay.

Hello all,

Just wanted to find out if anybody could recommend any of the bottled waters from supermarkets around Belfast etc, for various beer stales? Eg IPAs and American PAs, When using all grain. Which ones hav the closest target water profile etc?

Cheers

I've used both Tesco's Ashbeck and Asda's Eden Falls water but I do water adjustments using BeerSmith.

Asda Eden Falls:







Calcium11ppm
Magnesium3ppm
Sodium9ppm
Sulfate9ppm
Chloride12ppm
Bicarbonate30ppm

Tesco Ashbeck:







Calcium10ppm
Magnesium2.5ppm
Sodium9ppm
Sulfate10ppm
Chloride12ppm
Bicarbonate9.5ppm

Pretty good that you can get that level of detail on the labels (or did you need to email each of them for info?)
Title: Re: Water Analysis
Post by: Onthebrew on September 12, 2016, 04:33:17 PM
cheers, maybe give one of those a try then. 

typically for an IPA , and a black IPA, what sort adjustments might i need? can i wait untill measuring themash PH?

Asda have those details on their website but there a little bit of working out for the Tesco one.

Ok here quoted profiles for lidl's carrick glen and my offices water cooler water just EAU.

Calcium seems much higher for these compared to tesco/asda and bicarbonate of the scale with the carrick glen, but would that be good for dark ales?

Also got report of tap water.


Just EAU:
Calcium   92ppm
Magnesium   1ppm
Sodium   7ppm
Sulfate              
Chloride   14ppm
Bicarbonate   
Ph.                   7.5

carrick glen:
Calcium   80
Magnesium   23
Sodium   18
Sulfate    31
Chloride   20
Bicarbonate   293

Tap water. Classed mod soft
Calcium   33
Magnesium   5
Sodium   13
Sulfate    45
Chloride   18
Bicarbonate   81

So can I clarify as I'm not great on the water treatment options

Calcium - flakes from homebrew store
Magnesium - also from homebrew store
Sodium - standard salt
Sulfate - are these the Epsom salts
Chloride - homebrew store
Bicarbonate - standard bicarb soda in any shop

I basically want to get all the possible additions for water treatment. I'm sure I got the above horrendously wrong
Title: Re: Water Analysis
Post by: robotmonkey on September 13, 2016, 10:53:08 AM
It's a little bit more complicated than that. The ions are formed in compounds so it's about get the balance right. You can't get chloride on its own but you can get table salt (sodium chloride NaCl) or calcium chloride (CaCl) but obviously they contribute sodium and calcium respectively.

Try using this calculcator http://www.brewersfriend.com/brewing-water-target-profiles/

I've also attached an example of the calculator from BeerSmith which I've found to be pretty useful for this.
Title: Re: Water Analysis
Post by: Onthebrew on September 13, 2016, 02:10:54 PM
that Beersmith tool looks great  so i guess you check the supermarket options etc for one that is a close match to your target water then enter them both and  make the additions needed.

Does anyone no a source for target profiles for specific beer types- as opposed to areas?

also in the meantime as a quick fix, if i check the mash ph pre boil and its too low, or too high - whats best way to raise it or lower it? can you change it post boil? for my first few brews will probably keep it simple if pos.

cheers.

A few notes (https://gcbrewers.wordpress.com/adding-water-profiles-to-beersmith/) with some different profiles (https://gcbrewers.wordpress.com/beersmith-water-profiles/), e.g. Light & hoppy, light & malty, balanced (from brewersfriend calculator)

Remember to add your local / bottled water details.

I have r.o water at home. So if I want to replicate a profile I just add each addition as all minerals will be at zero?

Essentially yes. If you are using RO water then all you need is gypsum (calcium sulphate), calcium chloride, and sodium bicarbonate. You don't need to worry about magnesium, the mash adds more than enough.

Post by: DEMPSEY on September 13, 2016, 05:21:46 PM
If you use RO then you set up your water as RO and then all you do is add one of the water profiles to your recipe and beersmith will add the necessary salts to your recipe.  ;)
