The Brewhouse Efficiency Calculator calculates your mash extraction efficiency in percentage terms and points per pound per gallon (ppg). The Efficiency Calculator is useful for all grain beer brewers to calculate their actual efficiency at extracting sugars from the grain during the mash. Enter the pre-boil gravity, amount of grains, total extracted wort and the grain bill.
