The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 74,900-acre "Elkton Oregon" viticultural area in Douglas County, Oregon. The viticultural area lies totally within the Umpqua Valley viticultural area and the multi-county Southern Oregon 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.
