The Alcohol By Volume (ABV) Calculator is a tool to help wine makers determine the alcohol content of their wine. It uses the specific gravity (SG) readings taken before and after fermentation to calculate the ABV percentage.
Tip: Make sure to adjust for temperature if your hydrometer is not calibrated for the temperature of your wine.
The ABV is calculated using the following formula:
ABV (%) = (OG - FG) × 131.25
This formula assumes standard fermentation conditions and may vary slightly depending on your yeast strain and process.
