The Vineyard

Split Rock Vineyards are carefully farmed to produce a very low per-acre grape yield, ensuring the highest quality fruit on every vine. We harvest and craft our wines with a balance of traditional and modern techniques, and produce about 500 cases per year.

The Terrior

Paso Robles Wine Country is centrally located between San Francisco and Los Angeles along California’s Central Coast. Even though the Franciscan Friars brought winemaking to the region back in the late 1700s, the area was largely known for cattle ranching until the 1970s. Since then, the cattle have given way to grapes—over 200 wineries producing across the 600,000 acre Paso Robles AVA. With a greater day-to-night temperature swing than any other appellation in California, distinct microclimates, diverse soils and a long growing season, Paso Robles is a unique wine region blessed with optimal growing conditions for producing wines made from Rhône varietals. More than 40 wine grape varieties are grown in Paso Robles, ranging from Cabernet Sauvignon and Merlot to Syrah, Viognier and Roussanne, as well as Zinfandel, the area’s heritage wine varietal.

The Wine

Our Estate Cuveé, inspired by the region’s known “Super Paso” wines, is a bold combination of Bordeaux and Rhône varietals. A play on the “Super Tuscan,” Super Paso wines have been gaining popularity and impressive awards and scores. Featuring Cabernet Sauvignon and Syrah at their base and a small blend of Petit Verdot—the Cab brings in the structure and the tannins, while the Syrah gives the wine fruit forward personality. The Petit Verdot is a late maturing Bordeaux grape that adds a “classic style to the fleshy nuances of Cab and Syrah.” Think of a great Napa Cab meets a classic Southern Rhône “Chвteauneuf-du-Pape.” We love the flavor of blackcurrants and cedar in the Cab and the big fruit and smokey edge of the Syrah. All this sounds pretty fancy, but the bottom line for us is we just love the power and purity that our Estate Cuveé and other Super Paso wines embody.

We also have a small block of Petite Sirah, our wild-hair varietal, that, as of now, stands alone proudly. We are increasingly seeing Petite Sirah finding its way into other blends in the Paso area, though, so stay tuned! Petite Sirah, also known as Derive, is a variety of red wine grape primarily grown in France, Israel, California, and Australia. It produces tannic wines with a spicy, plummy flavor, and it is more and more being produced as a stand-alone wine. It usually has a very dark, inky color. We have a feeling it could end up being a real sleeper for William Robert Wines!
