Proof and Alcohol By Weight
In the United States, a few states regulate and tax alcoholic beverages according to alcohol by weight (abw), expressed as a percentage of total mass. Some brewers print the abw (rather than the abv) on beer containers, particularly on low-point versions of popular domestic beer brands.
At relatively low abv, the alcohol percentage by weight is about 4/5 of the abv (e.g., 3.2% abw is equivalent to 4.0% abv). However, because of the miscibility of alcohol and water, the conversion factor is not constant but rather depends upon the concentration of alcohol. 100% abw, of course, is equivalent to 100% abv.

Famous quotes containing the words proof, alcohol and/or weight:
“a meek humble Man of modest sense,
Who preaching peace does practice continence;
Whose pious life’s a proof he does believe,
Mysterious truths, which no Man can conceive.”
—John Wilmot, 2d Earl Of Rochester (1647–1680)
“No power on earth or above the bottomless pit has such influence to terrorize and make cowards of men as the liquor power. Satan could not have fallen on a more potent instrument with which to thrall the world. Alcohol is king!”
—Eliza “Mother” Stewart (1816–c. 1908)
“as his weight wilts
and he is on a porch
that won’t hold my arms,
or the legs of the race run
forwards, or the film
played backwards on his grandson’s eyes.”
