Alcohol Content Comparison
Overview
This calculator estimates the Alcohol By Volume (ABV) of your homebrew using the standard formula. It requires the Original Gravity (OG) taken before fermentation and the Final Gravity (FG) taken after fermentation.
💡
Pro Tips
Ensure your gravity readings are temperature corrected.
Most beers finish with an FG between 1.005 and 1.020.
Sanitize your hydrometer properly before every reading.

Fun Facts
"The formula used is (OG - FG) × 131.25, widely accepted for standard strength beers."
"Hydrometers are calibrated for water at a specific temperature (usually 60°F/15°C)."
