Relentless is a blend of Syrah and Petite Sirah that originates in a rugged, sloping vineyard planted in the chaparral foothills of the Vaca Mountains, along Napa Valley's drier, cooler southeast corridor. The soul of the wine, though, comes from its namesake, our longtime winemaker, Elias Fernandez, who the Shafer family honors with this proprietary blend for his relentless pursuit of quality.
