Winemaker notes: The Somerston Estate is our 1628-acre property with 12.5 acres planted to Petite Sirah vines. Located high in the eastern hills of Napa Valley, Somerston sits at elevations ranging from 820 to 2400 feet. We selected this Petite Sirah from five different hillside blocks. The harvest for Petite Sirah started in the early morning hours beginning on September 22nd and the last block was harvested on October 18th.
