Brewing tool
Efficiency Calculator
Check how much of the grain potential made it into the wort you collected.
Guide
Before you start
Use the volume and gravity you actually collected. The default potential of 36 PPG is a practical all-grain starting point.

Method
How this is estimated
The tool compares the gravity points collected in the wort with the potential points available from the grain bill.
efficiency ≈ actual gravity points ÷ potential points × 100
Safety and limits
A few notes
Efficiency depends on accurate volume, gravity, and grain potential. Mixed grain bills are only as accurate as the potential value you enter.
Use accurate measurements for the best estimate.
