The correct agency that regulates American Viticultural Areas (AVAs) is the Alcohol and Tobacco Tax and Trade Bureau (TTB). This federal agency is responsible for overseeing the production and labeling of alcoholic beverages, including wine, which encompasses the establishment of AVAs.

AVAs are designated grape-growing regions within the United States, and the TTB enforces regulations concerning the geographical boundaries, naming, and labeling of these areas to ensure accuracy and protect consumer information. While both the Tax and Trade Bureau and the Alcohol and Tobacco Tax and Trade Bureau refer to the same agency, the name likely has variations in common usage.

The other agencies mentioned, like the Food and Drug Administration, primarily focus on food safety and drug approval, and the Department of Agriculture covers a wider range of agricultural issues but does not have specific regulatory authority over AVAs. Therefore, the TTB is the appropriate choice for the regulation of American Viticultural Areas.
