(SBV) Standard measurement of alcohol in beer.
The measure of the amount of space the alcohol in a beer takes up as a percentage of total volume. This is the worldwide standard for measuring the alcohol content in beer. The United States traditionally used alcohol by weight (ABW) to measure alcohol content, but more and more American brewers are now adopting ABV.
As required by law, wineries must state the alcohol level of a wine on its label. This is usually expressed as a numerical percentage of the volume. For table wines the law allows a 1.5 percent variation above or below the stated percentage as long as the alcohol does not exceed 14 percent. Thus, wineries may legally avoid revealing the actual alcohol content of their wines by labeling them as "table wine."
