Washington, D.C. ? The Alcohol and Tobacco Tax and Trade Bureau (TTB) will publish a notice of proposed rulemaking in the Federal Register on Wednesday, June 22, 2016, proposing to amend its labeling and recordkeeping regulations in 27 CFR part 24 to provide that any standard grape wine containing 7 percent or more alcohol by volume that is covered by a certificate of exemption from label approval may not be labeled with a varietal (grape type) designation, a type designation of varietal significance, a vintage date, or an appellation of origin unless the wine is labeled in compliance with the standards set forth in the appropriate sections of 27 CFR part 4 for that label information. TTB is also proposing to amend its part 4 wine labeling regulations to include a reference to the new part 24 requirement.
TTB is taking this action in response to concerns raised by wine industry members and members of Congress regarding the accuracy of label information on certain wines covered by certificates of exemption from label approval, particularly regarding the labeling of certain wines that may not meet the part 4 regulatory requirements for using American viticultural area (AVA) names.
