I'm about to brew a batch of BVIP and rather than randomly throwing a tsp. of CaCO3 in the mash like I've always done, I'm sitting here with Palmer's spreadsheet trying to calculate my additions. My water..
The beer color comes out to 45 SRM and according to the spreadsheet 450 is the median RA to shoot for. 6.5 gal. of mash water. If I add 5 gr. of CaCO3, 3 gr. of CaCl2 (to balance the sulfates), and 4 gr. of baking soda, it only gets me up to 160 and those amounts are enough to start me worrying. What to do? Do I call it close enough or go crazy and add more?
