Our family patriarch

Named for our family patriarch, Stefano Riboli, the Stefano Vineyard is located in the prestigious El Pomar District AVA of Paso Robles. This unique region exhibits warm daytime temperatures, but is highly influenced by cool afternoon breezes from the Templeton Gap. The region’s Arbuckle-Positas soils are filled with multicolored rocks of all shapes and sizes, creating steep hillsides. All of these factors contribute to the deeply colored, concentrated wines which come from Stefano Vineyard.
