TTB is seeking comments on the grape names proposed to insure accuracy. They would like to hear from wineries that may want to use the names on their wine labels. The majority of the grape names proposed are hybrid grapes.
The grape names have been proposed by growers and winemakers in each case. Some of the names are already allowed pending formal approval by the TTB. The list of approved grape names has not been updated since 2002.
Here is the link for the Notice of Proposed Rulemaking. TTB is seeking comments until March 21, 2011.
