TTB, acronym for the Alcohol and Tobacco Tax and Trade Bureau, the US regulatory body responsible for AVA approvals, federal taxation, and label approvals and winemaking protocols (although states are permitted to enact more stringent rules than those applied nationally). TTB is an offshoot of the Bureau of Alcohol, Tobacco, and Firearms, which previously was the overseer of alcohol beverage regulation.
