The Alcohol and Tobacco Tax and Trade Bureau (TTB) is expanding the approximately 1,320-square mile "Monticello" viticultural area in Albemarle, Greene, Nelson, and Orange Counties, in Virginia, by approximately 166 square miles, into Fluvanna County, Virginia. The established viticultural area and the expansion area are 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.
