This might also be useful. It is a statement of the mission of the U.S. Treasury Department's Alcohol and Tobacco Tax and Trade Bureau (TTB).

TTB’s Advertising, Labeling, and Formulation Division (ALFD) implements and enforces a broad range of statutory and compliance provisions of the Internal Revenue Code (IRC) and the Federal Alcohol Administration Act (the Act). The Act requires importers and bottlers of beverage alcohol to obtain certificates of label approval or certificates of exemption from label approval (COLAs) for most alcohol beverages prior to their introduction into interstate commerce. ALFD acts on these COLAs to ensure that products are labeled in accordance with Federal laws and regulations.

ALFD also examines formulas for wine and distilled spirits, statements of process, and pre-import applications filed by importers and proprietors of domestic distilled spirits plants, wineries, and breweries for proper tax classification and to ensure that the products are manufactured in accordance with Federal laws and regulations.


Also, has anyone read the Peter Krass biography of Jack Daniel, Blood & Whiskey? I wonder if he addresses any of this.
