The Department of Treasury is considering adding nearly 28,000 acres to a viticultural area in Northern California.

In a notice of proposed rulemaking, Treasury’s Alcohol and Tobacco Tax and Trade Bureau (TTB) says it will invite comments on expanding the Clarksburg viticultural area from its current 64,640-acre expanse. The area, which is located in Sacramento, Solano, and Yoho Counties, would be further expanded into Sacramento and Solano Counties.

According to TTB, viticultural areas are used “to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.” The areas are grape-growing regions with “distinguishing features” and allow vinters and consumers “to attribute a given quality, reputation, or other characteristic of a wine made from grapes grown in an area to the wine’s geographic origin,” TTB noted in a Federal Register Notice.

TTB will accept comments for 60 days on the proposed change.
