Red Mountain in southeastern Washington, near the Tri-Cities, lies between Rattlesnake Mountain and Candy Mountain in a landscape shaped by the Columbia, Snake, and Yakima rivers. Named for the reddish spring bloom of drooping brome on its slopes, it is also one of Washington’s notable wine landscapes. In 2001, it was recognized as an American Viticultural Area within the larger Yakima Valley viticultural area. Its south-facing slopes, sandy loam soils high in calcium, alkaline conditions, good air drainage, light soils, low rainfall, and long growing season support vineyards that produce prominent wine grapes, and many leading Washington wine estates source fruit from its slopes.
