Each equivalent of Ca(OH)2 would raise the alkalinity by 1 equivalent. The calcium would reduce it by 1/3.5 equivalent. The net gain is thus 2.5/3.5 = 0.71 Eq. I'd rather have him undershoot than overshoot.

Hey folks,

So going to brew again next chance I get and use a better volume of water. That being said, for my RIS, I have made this water profile:

Calcium: 73
Magnesium: 31
Sodium: 60
Sulfates: 77
Chloride: 67
Bicarbonates: 300

For a really roast, big RIS with mild hop notes I think this would work from what research I have done. I am getting, according to the Kaiser sheet, a mash between 5.4 and 5.5 pH. Seems reasonable?
