SONOMA: The Yorkville Highlands AVA, approved in 1998, is located in the southwestern corner of Mendocino County, between Sonoma County's Alexander Valley to the South and Mendocino County!s Anderson Valley to the North. The region is 25 miles long, roughly in the shape of rectangle and bisected by Highway 128 which runs the length of the AVA. The region!s terrain is hilly and forested, with elevations ranging from 1,078 to 2,442 feet above sea level.
The distinguishing features of the Yorkville Highlands AVA are rocky soils with a high gravel content and the climate, which is cooler than Alexander Valley but warmer than Anderson Valley, and significantly cooler at night than the surrounding areas.
