Abbreviation for Alcohol and Tobacco Tax and Trade Bureau. This US office has been in existence since the beginning of 2003 and emerged from the BATF (Bureau of Alcohol, Tobacco, Firearms and Explosives). As a result of the "Homeland Security Act" that came into force in 2002, the tasks were divided. The corresponding responsibilities and functions relating to alcohol and tobacco were separated from the BATF and assigned to the TTB. These include the approval of the design, conditions and designation of wine labels and packaging and, in part, wine advertising and trade; the approval or rejection of official permits for new wineries; the monitoring of records and the tracking of production techniques, quantities, logistics and the collection of alcohol taxes; and the approval or rejection of applications for new wine-growing regions in the USA. The authority is thus responsible for the US AVA (American Viticultural Area) appellation system. TTB is assigned to the Ministry of Finance, BATF remains assigned to the Ministry of Justice.
