ABV Calculator: Calculate Alcohol By Volume for Your Homebrew

Calculate Your Brew's Alcohol by Volume

The specific gravity before fermentation.
The specific gravity after fermentation.

Discover the exact Alcohol by Volume (ABV) of your homemade beer, wine, or cider. Our precise ABV calculator helps homebrewers quickly determine their beverage's strength using original gravity (OG) and final gravity (FG) readings. Understand your brew better and perfect your recipes.

Formula:

The Alcohol by Volume (ABV) percentage is calculated using the following formula:
ABV % = (Original Gravity (OG) - Final Gravity (FG)) × 131.25

Where:

  • Original Gravity (OG): The specific gravity of your wort or must before fermentation begins.
  • Final Gravity (FG): The specific gravity of your fermented beverage after fermentation is complete.
