I came across this equation on the website linked directly below it.
pH = 5.8 + [0.028 x {(Total alkalinity(as CaCO3) x 0.056)-(Ca (ppm) x 0.04)-(Mg (ppm) x 0.033)}]
(Where 5.8 = the malts presumed DI mash pH)
http://www.winning-homebrew.com/mash-pH.html
The formula should more generically and properly be stated as:
pH = (DI mash pH) + [0.028 x {(Total alkalinity(as CaCO3) x 0.056)-(Ca (ppm) x 0.04)-(Mg (ppm) x 0.033)}]
Is this merely someones empirical (ballpark) pH shift calculating equation, or does it have a basis derived from brewing science? Either way, does it closely model reality with respect to mineral induced mash pH shift?
