Yorkville Highlands AVA is located in Mendocino County in California. It was was approved as an AVA in 1998 because of its distinctive soils and temperatures relative to neighbouring Anderson Valley (see Anderson Valley AVA). Yorkville Highlands’ rocky soils, with high-gravel content, differ from the loamy, clay soils common to neighbouring appellations. These highly-porous soils allow for superior water drainage, forcing the roots of vines to dig deep for water. The result is low-vigor vines that yield concentrated fruit. The moderate temperatures of the AVA are suitable for Sauvignon Blanc, but also show great promise for Bordeaux reds like Cabernet Sauvignon and Merlot.
