Alcohol Fact Labeling Methods

Methods Used to Validate Calorie, Fat, Carbohydrate, and Protein Content Statements on Alcohol Beverage Labels and Advertisements

TTB periodically reviews labeling and advertising claims by taking samples of alcohol beverage products for validation purposes. To validate these claims, we use the TTB methods referenced below, which are applicable to all alcohol beverages and based on AOAC methods. These methods of analysis meet the definitions referenced in Section III of TTB Procedure 2020-1. We consider your advertising and labeling claims acceptable if, when we evaluate your product using these methods, we find that they fall within the tolerance levels specified in Section V of this procedure.
