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:
“War is a beastly business, it is true, but one proof we are human is our ability to learn, even from it, how better to exist.”
—M.F.K. Fisher (1908–1992)
“The sacrifice to Legba was completed; the Master of the Crossroads had taken the loas’ mysterious routes back to his native Guinea.
Meanwhile, the feast continued. The peasants were forgetting their misery: dance and alcohol numbed them, carrying away their shipwrecked conscience in the unreal and shady regions where the savage madness of the African gods lay waiting.”
—Jacques Roumain (1907–1945)
“The only thing of weight that can be said against modern honour is that it is directly opposite to religion. The one bids you bear injuries with patience, the other tells you if you don’t resent them, you are not fit to live.”
—Bernard Mandeville (1670–1733)
