So I have been using Bru'n water to calculate my acid additions with great success. However I purchased Beer smith 3 so I could cut down time and just use the one program to do all of the calculations. But the calculations the program are giving me are just ridiculous ! the calculation BS gives me is- for a 25.5L mash with alkalinity of 84.4 - I will require 9.2 ml of 96% phosphoric acid to drop the mash Ph from 5.67 to 5.2. Where as in Bru'n water if I was to add 9.2ml of 98% phosphoric acid to the 25.5L mash it gives me a calculated mash ph of 4.21. I am just wondering if who ever has come up with these calculations has even tested the theory practically? I know Bru'n water's calculations are correct because i have tested them with a Ph meter and found them to be very accurate.
Has anyone else found this to be the case ?
