Pope Valley is not an official AVA, though if the vintners who grow grapes and make wine there have their way, it will someday gain AVA status. The area is 25 miles east of the Silverado Trail above Rutherford and St. Helena, near Lake Berryessa, and proposals by local vintners would include about 108 square miles of land. Elevation here ranges from 500 to 1,400 feet and temperatures are more extreme that Napa Valley appellations closer to water.
