The US Alcohol and Tobacco Trade Tax Bureau maintains a list of approved wine grape names for use on labels by US vintners.
Based on current regulations, a wine producer must follow these rules regarding the use of grape names on a bottle of wine:
- They may only use grape variety names approved by TTB.
- If they use a grape varietal name, an appellation of origin must also appear on the label. The name of a single grape can appear on the label if the wine is made of at least 75% of that grape, although there are exceptions.
- The wine must be made from a minimum percentage of the grape varietal.
- They may use two or more grape varietal names on the label as long as those two grapes are the only grapes used to make the wine.
