Distillery calculation guide
ABV vs Proof
A working reference for distinguishing alcohol by volume from US proof.
Working method
This guide uses the same verified calculation engine as the corresponding Stillbench bench tool. Keep units consistent, use measured values, and treat the result as a production-planning estimate.
Verify before production
Temperature, instrument calibration, alcohol-volume contraction, local reporting rules, and operating conditions can affect production measurements. Verify the result using the procedures appropriate to your operation.
