Jump to navigationJump to search

Alcohol by Weight (ABW) is a measure of how much alcohol is in a beverage, expressed as a percentage of the total beverage weight. The US often quotes alcohol values by weight (not volume) and the Bureau of Alcohol, Tobacco and Firearms (BATF) uses the weight measurement. To calculate the alcohol by weight, first calculate the Alcohol By Volume (ABV) and then use the following formula:

ABW = ABV * 0.79336
