A Distinct Terroir

Split Rock Ranch Vineyard is the farthest west vineyard located in the coveted West Paso Robles AVA on California’s Central Coast. The vineyard’s planting of Rhone and Bordeaux varietals in sandstone soils delivers low yields of quality fruit. Our winemaker’s highly selective approach results in limited production, authentic and structured wines that are dark, delicious, and silky.

Nurturing Each and Every Wine

As a family owned and tended vineyard, we are thankful for the joy this land brings us and in return we nurture the fruit it bestows, and each and every wine created at Split Rock Ranch. The vineyard is carefully farmed to produce a very low per-acre grape yield, ensuring the highest quality fruit on every vine. Harvested and crafted with a balance of traditional and modern winemaking techniques, we produce about 500 cases per year.

William Robert Estate wines represent our rich terroir, highly selective crop management, and infinite patience in the barrel aging. Yes, mother nature did most of the work, but this wine has our fingerprints all over it. And come crush season, you’ll probably notice a few of our toe-prints as well.
