The Terrain of Guenoc Valley Wine Region
The Effect of Guenoc Valley Soil and Terrain on its Wine
The soils in Guenoc were created by pyroclastic lava flows long ago. They are loamy, quite deep, and drain well. There is also a lot of volcanic gravel and serpentine in the ground. The elevation of the AVA ranges from 700 to 1,400 feet above sea level.
Langtry Estate is the only winery in the region and owns the entire AVA plus over 17,000 additional acres. Despite this property’s large size, it contains only 300 acres of vineyards planted in the choicest locations. Many of the vines are grown on steep, terraced hillsides.
Langtry’s Tephra Ridge Vineyard is particularly prized for Cabernet Sauvignon. Tephra Ridge is planted at 1,400 feet on volcanic ridges that surround the Guenoc Valley. Guenoc’s Petite Sirah and Sauvignon Blanc are grown on the valley floor at about 1,000 feet above sea level.
