The Shafer Vineyards Napa Valley Relentless is a blend of 86% Syrah and 14% Petite Sirah. In the glass, the 2017 Relentless has a deep garnet purple color and fragrant notes of black pepper, licorice and violet over a core of prune, mulberry plus some earthy notes. On the palate, the Rlentless is medium to full bodied and excels in purity and freshness with ripe, round tannins and plenty of pepper and spice layers, finishing refreshingly savory.
