The Alcohol and Tobacco Tax and Trade Bureau is revising its list of materials authorized for the treatment of wine and juice, and its list of processes authorized for the treatment of wine, juice, and distilling material. Specifically, we are adding new material and process listings, and amending the limitations for some existing listings pertaining to wine and juice. We are seeking comments from all interested parties on our view that the materials and processes covered by these changes are consistent with good commercial practice in the production, cellar treatment, or finishing of juice or standard wine.
