Brewing water tools
Single-purpose calculators from the brewwtr chemistry engine — the same validated math as the full app, one question at a time. For the whole picture (mash pH, mineral additions, sparge acidification together), open the calculator.
Alkalinity → bicarbonate converter Turn a water report’s total alkalinity (as CaCO₃) into the bicarbonate and carbonate concentrations brewing calculators use.Lactic acid calculator How many milliliters of lactic acid to bring a volume of brewing water to a target pH, from exact carbonate equilibrium.Water hardness converter Convert hardness and alkalinity between ppm as CaCO₃, German °dH, English (Clark) degrees, grains per gallon, and meq/L.Beer color (SRM) calculator Estimate beer color from your grain bill and batch volume with the Morey equation — SRM, EBC, and a color swatch.Dilution calculator Blend tap water with distilled or RO and see every ion — and your alkalinity — drop proportionally.
