Gravity Calculator

The following calculator estimates the boil and original gravity of an all-grain batch. If you include the brewhouse efficiency it will adjust the gravity calculations. If you include the actual original gravity, it will calculate your efficiency.

Batch Variables
Boil Volume (gallons) Brewhouse Efficiency
(Optional to show adjusted gravities)
Final Volume (gallons) Actual Original Gravity
(Optional to calculate efficiency)
