Yorkville Highlands was approved as an AVA in 1998 because of its distinctive soils and temperatures relative to neighboring Anderson Valley. Yorkville Highlands’ rocky soils, with high-gravel content, differ from the loamy, clay soils common to neighboring 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.
