Starting in the east, near the northern boundary of the Santa Ynez Valley AVA, we find perhaps the area’s most acclaimed sub-region: Alisos Canyon. Running east of Highway 101 along Alisos Canyon Road, this area is paradise for Rhone varieties, though Cabernet Franc and Gamay also have potential. The canyon is home to the famed Thompson Vineyard, which has produced legendary Syrahs for 20 years.
…at Thompson, is Tierra Sandy Loam, an alluvial soil providing more textural breadth in the wines. The Third Twin (formerly Los Tres Burros), Sine Qua Non’s site above Thompson, shifts into San Andreas-Tierra Complex, a much sandier, sandstone-derived soil.Los Alamos Valley: An In-Depth Look At Santa Barbara County’s Unsung Treasure
