Mineral additions for stout

(1/2) > >>

tygo:
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?

ndcube:
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...

a10t2:
I'd probably use CaCl instead of or in addition to the gypsum, unless you're going for a hoppy stout.

altered_states:
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.
