This calculator determines the ABV of your beer based on the gravity change before and after fermentation. If you took an original gravity reading (or had estimated OG), and also took a final gravity (FG) reading prior to adding priming sugar at bottling you can find out your batch's alcohol by volume ABV.
Calculate the alcohol content of your homebrew beer or any liquor based on its specific gravity. Learn about alcohol formula, facts, myths, history and more.
Estimate the alcohol content and units of your homemade brew using original and final gravity readings. Choose from different formulas and units of measurement, and compare ABV and proof for US and UK.
This is a calculator to accurately predict Alcohol By Volume for homebrewed beer. The Original Gravity (OG) and Final Gravity (FG) readings input into the calculator are usually taken with a Hydrometer.
Estimate the alcohol by volume (abv) of beer based on original and final specific gravity values. Learn the formulas, methods, and factors that affect the accuracy of abv estimation.
Enter your original gravity and final gravity to calculate the alcohol by volume of your home brew. You can also revert to generic beer settings or adjust the gravity units.
Calculate alcohol by volume (ABV) based on gravity change using standard or alternate equations. Choose Plato or Standard Gravity units and enter original and final gravity values.
