## Abstract

The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 7,296-acre "Winters Highlands" viticultural area in portions of Solano and Yolo Counties in California. The Winters Highlands viticultural area is not located within any other established viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.
