The TTB has issued their final ruling on proposed grape variety names for use on domestic wine labels. The TTB's statement on the ruling is below, as is the link to the final rulemaking.
This document adopts, as a final rule, a proposal to amend the Alcohol and Tobacco Tax and Trade Bureau regulations by adding a number of new names to the list of grape variety names approved for use in designating American wines, and to include in the list several separate entries for synonyms of existing entries so that readers can more readily find them. These amendments will allow bottlers of wine to use more grape variety names on wine labels and in wine advertisements.
Effective Date: This final rule is effective November 28, 2011.
