In February we posted about The Alcohol and Tobacco Tax and Trade Bureau’s proposed rule to add new names to the approved list of grape variety names that can be used to designate United States wines. The original post is available here. The TTB has completed its rulemaking process and the revised rule will go into effect November 28, 2011, the Monday after Thanksgiving. More than 50 new names were added to the list, including some popular well known varietals like Grenache Blanc and Grüner Veltliner. To aid in locating information within the new and lengthy list, the TTB also included synonyms for a number of entries. Full details on the revised rule are available here.
