Dear Dr. Vinny,
Isn't it true that in the United States wine producers are always required to list the alcohol content of their wines on the label? I had always assumed so, but I recently drank a Margerum Sauvignon Blanc Sybarite 2007 and did not see the alcohol content listed anywhere on the label, front or back.

The Alcohol and Tobacco Tax and Trade Bureau (or TTB) requires the percentage of alcohol by volume listed on the label for wines containing 14 percent or more alcohol. Below 14 percent, it's up to the producer if they want to list it; if not, the label needs to read "white table wine" or "red table wine." Since the same organization defines wine as having at least 7 percent alcohol, when you don't see an alcohol percentage listed, you can assume that it falls between 7 and 14 percent.
