Homebrew ABV Calculator
This calculator helps homebrewers determine the Alcohol by Volume (ABV) of their brews. Enter the original and final gravity values to see your brew's ABV.

Data Source and Methodology
The calculations are based on standard brewing formulas and sourced from Brewer's Friend ABV Calculator.
All calculations are strictly based on the formulas and data provided by this source.
The Formula Explained
ABV Formula: ABV = (OG - FG) × 131.25
Glossary of Terms
- Original Gravity (OG): The specific gravity of the wort before fermentation.
- Final Gravity (FG): The specific gravity of the beer after fermentation.
- ABV: Alcohol By Volume, the percentage of alcohol in the beverage.
How It Works: A Step-by-Step Example
For example, if your Original Gravity (OG) is 1.050 and your Final Gravity (FG) is 1.010, the ABV is calculated as follows:
ABV = (1.050 - 1.010) × 131.25 = 5.25%
Frequently Asked Questions (FAQ)
What is ABV?
ABV stands for Alcohol by Volume, a standard measure used worldwide to quantify the amount of alcohol (ethanol) contained in an alcoholic beverage.
How is ABV calculated?
ABV is calculated by taking the difference between the original gravity (OG) and the final gravity (FG) of the brew, and then using a specific formula.
Why is my ABV calculation important?
Knowing the ABV of your brew is important for understanding its strength and for labeling purposes if you plan to share or sell your brew.
Can I use this calculator for any type of brew?
Yes, this calculator can be used for beer, mead, cider, and other types of homebrews.
What if my gravity readings are outside the typical range?
Ensure your hydrometer is calibrated and readings are taken at the correct temperature.
