Mineral additions for stout
« on: December 23, 2009, 06:45:49 PM »
Going to brew a 5 gallon batch of stout using these grains:

8.00 lb       Marris Otter Pale Malt (UK) (4.6 SRM)     Grain        72.72 %       
2.00 lb       Barley, Flaked (1.7 SRM)                  Grain        18.18 %       
1.00 lb       Roasted Barley (300.0 SRM)                Grain        9.10 %       

My water profile is:

Na 22
Ca 46
Mg 11
SO4 21
Cl  23
HCO3 121

I was thinking of adding 2.5g of chalk and 1g of gypsum to bring the water up to:

Ca 111
SO4 51
HCO3 200

Am I going overboard on the mineral additions?

I don't think it's overboard.  You can try it and find out.

If your pH is too low you can add more chalk to the mash.

not at all - if that's overboard, some folks are at the bottom of the sea...

I'd probably use CaCl instead of or in addition to the gypsum, unless you're going for a hoppy stout.
Beer is like porn. You can buy it, but it's more fun to make your own.

Looks good.  I brew with well water - 289 ppm bicarbonate - makes a good stout straight from the tap.  Like a10t2 wrote, I would add some CaCl.

I always try to raise my Ca levels with CaCl instead of gypsum for stouts/porters.

Let me know how it turns out as I'd be interested in making a peanut butter beer myself.  I've always liked the peanut butter Blue Moon at the GABF, but I'm also the kind of person who eats peanut butter straight from the jar because everything else just gets in the way.
Why can't it be all brewing, all the time?
