MASH EFFICIENCY







More Info [+]
Calculates the percentage of total available sugars that were extracted from the grains during the mash and sparge process.

REFRACTOMETER










More Info [+]
Converts refractometer readings taken of wort (Brix WRI) to their actual value in Brix / Plato and Specific Gravity. Supports alcohol correction of refractometer readings when calculating FG (which requires OG).

ALCOHOL BY VOLUME








More Info [+]
In general the ABV of the beer will be similar to the kilogram/pounds of grain. However the ABV will depend on how you mash and ferment so it is best to use this calculator to get an accurate figure.
