Hello All,
Based on my latest home brewing experience, I decided to move forward with RO water and get into water chemistry.
Now. All the time I had been said that 1 - 2 tbs of Calcium Chloride Dehydrate will be suitable to adjust the pH of the mash and I have been doing this blindly for a couple of years.
Based on my calculations, 1g of CaCl2 Dehydrate delivers 14.4 ppm of Ca2+ and 25.5 ppm of Cl-.
Since CaCl2 density is 2.15 g/ml and 1 tbs = 15 mL, 1 tbs would deliver 32.3 g of CaCl2. Assuming that I add 2 tbs of CaCl2 to the mash and don't add any to the sparging water, AND I add the same amount of sparging water relative to the mash volume, then the actual amount added would be 1 tbs and not 2 tbs because of dilution.
Yet, 32.3 grams of CaCl2 would deliver 14.4 ppm X 32.3 g = 465.1 ppm of Calcium and 823.7 ppm of Chloride!!!
Please let me know if I am missing something.
Thanks, Nil
