Easiest Way To Calculate The Alcohol Content Of Your Wine

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!

Did you know that you can easily calculate the alcohol content of your beer or wine if you know your specific gravity (S.G.) readings at the beginning and end of the beer/wine making process?

To calculate the approximate value of the alcohol content in your beer/wine use the following formula:

Approximate Alcohol Content (%) =

Starting S.G.- Ending S.G.

0.0074

For example:

Starting SG = 1.090
Ending SG = 0.995

% Alcohol = 1.090 – 0.995 = 12.84

0.0074

> You can therefore say that the approximate alcohol content of this batch of wine is 12.84%

Note: This method assumes that difference in specific gravity is solely due to the conversion of sugar into alcohol
