This tool helps you accurately estimate the alcohol by volume (ABV) of your homebrewed beer.
ABV Calculator
This Alcohol by Volume (ABV) calculator estimates the alcohol content of your homebrew based on the original gravity (OG) and final gravity (FG) measurements. Additionally, the fermentation temperature is factored into the calculation for accuracy.
How to Use
- Enter your Original Gravity (OG) reading, which you should have taken before fermentation began.
- Enter your Final Gravity (FG) reading, taken after fermentation has completed.
- Enter the fermentation temperature in degrees Celsius.
- Click “Calculate” to see the estimated ABV percentage.
How It Calculates
The ABV is calculated using the formula: (OG – FG) * 131.25. The result is presented as a percentage. This calculation assumes that the measurement units for OG and FG are in the standard gravity format used in brewing. If temperature difference during measurements is substantial, results might need further correction.
Limitations
This calculator provides only an estimation based on given values. Variations in measurements, temperature, and yeast efficiency can affect the accuracy. Always use a hydrometer or a refractometer properly calibrated for the most reliable readings.
