Middleburg Virginia is an American Viticultural Area (AVA) in the northern Piedmont region of Virginia within Fauquier and Loudoun Counties about 50 miles (80 km) west of Washington, D.C. It is named for the town of Middleburg, Virginia and is bounded by the Potomac River to the north and by more mountainous areas, specifically, Catoctin and Bull Run Mountains to the east, Watery, Swains, Little Cobbler, and Hardscrabble Mountains to the south, and the Blue Ridge Mountains to the west. The area was established on September 12, 2012 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Rachel E. Martin, executive vice president of Boxwood Winery in Middleburg, Virginia, on behalf of herself and local vintners, proposing the viticultural area to be known as "Middleburg Virginia." The hardiness zone in the AVA is 7a.
