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?
