Turley's Old Vines blend draws from a carefully curated selection of California vineyard parcels—some too modest for individual designation, others newly acquired and being integrated into Turley's exacting farming philosophy. Sourced across seven regions including Napa, Sonoma, Mendocino, Lodi, Contra Costa, Amador, and Paso Robles, these 18 vineyard sites feature vines averaging 80 years in age, lending depth and complexity to this distinctive expression of California's winemaking heritage.
