Shannon Ridge is situated in a very distinct winegrape growing region, high above the northeast shores of Clear Lake in Lake County, California. Through a combination of geography, soils, climate, elevation, and wind, this area differs significantly from surrounding viticultural areas. Similar to other ultra-premium great wine growing regions around the world, High Valley has become an American Viticultural Area, in order to distinguish this extraordinary growing region. High Valley is defined by steep mountain ridges, which rise directly from the valley floor at an elevation of 1,700 feet above sea level to heights in excess of 3,000 feet. Approximately ninemiles long and three-miles wide, High Valley is in a rare east-west transverse in the Californian Coastal Range.
