How much of a water's measured alkalinity the mash actually has to overcome.
Alkalinity is titrated to the ~pH 4.3 carbonic end point, but a mash only
pulls the water down to ~5.4, at which pH about a tenth of the carbonate is
still bicarbonate and has not consumed any acid. Ignoring that overstates the
water's effect by roughly 10 %.
Type Declaration
"titrated-to-mash-ph"
Titrate the carbonate system from the water's pH to the mash pH. The default.
"full-alkalinity"
Treat the whole measured alkalinity as active. What most calculators do.
