Percentage Alcohol By Volume.

In commercial brewing, controlling and determining the gravity
(density) and alcohol content are of paramount importance.  Some
drinkers care about %ABV, too ;-)

This tool won't be of much to home brewers, I'm afraid--you need some
pretty expensive kit just to get the values to do the calculations
(refractometer, densitometer, full distillation kit and 5-6
d.p. balance to calculate the correction factors).
