Alcohol content must be stated on any wines containing more than 14% alcohol by volume. These wines, even if the level of alcohol is reached naturally, are considered “fortified” and taxed a a rate four times higher than wines under 14%. For wines under 14%, either the alcohol content may be stated or the designations “Table Wine” or “Light Wine” may be used, both phrases implying alcohol content within a range of 7% to 14%.
A latitude of 1% over or under the stated level is permitted on wines above 14%. A greater latitude of 1.5% is allowed on wines under 14% (although in no case is it allowed to exceed 14%). Many wines are labeled “alcohol 12.5% by volume” to take full advantage of this tolerance.
