Shafer Vineyards is a family-owned winery located in the Stags Leap District of Napa Valley. They are well-known for producing critically acclaimed wines, with a focus on Cabernet Sauvignon. Relentless is one of Shafer`s flagship wines, and it`s a blend of Syrah and Petite Syrah. The name Relentless pays tribute to the winery`s long-time winemaker, Elias Fernandez, who is known for his relentless pursuit of excellence in winemaking. The 2018 vintage was a very good year in Napa Valley, with a long, moderate growing season that allowed the grapes to ripen slowly and evenly, resulting in wines with excellent concentration and balance.
