Wine Advocate 92 points - The 2011 Syrah Relentless is certainly one of the lighter versions of this wine, but still merits an outstanding 92-point rating. A blend of 91% Syrah and 9% Petite Sirah, this wine shows more of a French style than other vintages because there is a hint of austerity and structural tannin that can be noticed through the roasted herbs, meaty blackberry and blackcurrant flavors and hints of blueberry and lavender. This is spicy, earthy, medium to full-bodied and probably will be the easiest and quickest to mature fully of any vintage of Relentless to date. Consume it over the next decade. (Oct 2014)
Wine Spectator 94 points - This big red brims with dark, rich, chunky blackberry and wild berry fruit, with notes of black licorice that edge toward prune. Maintaining a fine balance for its size, this is extracted, with firm, chewy, peppery tannins. Syrah and Petite Sirah. Best from 2015 through 2028. From California.J.L. (Sep 17 2014)
With this Syrah, Shafer honors Winemaker Elias Fernandez, whose relentless pursuit of quality has marked his nearly two decades at Shafer Vineyards. Multi-layered and expansive, Relentless combines the concentrated black cherry and blackberry flavors of Petite Sirah with black pepper spice and an earthiness derived from Syrah, both of which are planted in Shafer's hillside vineyard adjacent to the southern border of the Stags Leap District. A deep, dark and delicious wine, Relentless is aged for 25 months in French oak barrels.
