A remarkable wine, the 2010 Shafer Cabernet Sauvignon Hillside Select has gone from strength to strength since it was in cask. It is stunningly rich, with classic, fragrant notes of blackcurrants, blackberries, vanilla, graphite and spring flowers. It exhibits an opaque purple color, with a full-bodied, massive mouthfeel, but no heaviness, and again, a flawless integration of acidity, tannin, alcohol and wood. It’s classic California Cabernet, but beautifully put together, showing impeccable craftsmanship and fabulous potential. This is obviously a very young, infantile style of Cabernet that won’t hit its prime for at least another decade and last close to half a century, based on how older vintages that were less well-endowed have matured from Shafer.Robert Parker | 100 RPThe Shafer family has made compelling reds for decades and this one is a knock-out. Fabulous character of currants, mint, spice and wet earth. Juicy and fruity, with an intense chewy finish. Needs time to age.James Suckling | 98 JSBright, dark ruby to the rim. Very pure if subdued aromas of blackcurrant, black cherry, dark chocolate and minerals; conveys a strong Stags Leap terroir character. Enters the mouth voluptuous, broad and seamless but still youthful, showing a faintly inky reserve to its powerful dark fruit, licorice and mineral flavors. This Napa Valley masterpiece is developing at a snail’s pace. The finish goes on and on, with substantial fine-grained, toothcoating tannins in perfect balance with the wine’s fruit. Wonderfully sweet and voluminous but not excessively so, as there’s so much else going on here. This wine was only a tad more developed than a spectacular sample I tasted as part of a vertical tasting I did at the estate in 2016. A great vintage for Shafer.Vinous Media | 97 VMThe producer’s annual, highly anticipated 100% Cabernet Sauvignon, this comes from the wilds of the appellation’s rocky hillsides. This is a burly, distinctive and sizable wine, ripe yet refined, having been given three years in barrel and another in bottle before release. Chocolaty tobacco combines with pencil shavings and dense blackberry before finishing in an explosion of black pepper. Gorgeous, it will get even more interesting over time, through 2025.Wine Enthusiast | 95 WEPure, rich and intense, massive and well-built, with wall-to-wall ripe berry, currant, cedar and spice notes, framed by gutsy, chewy tannins and aided by the long, intense, layered finish. Drink now through 2027. 2,400 cases made.Wine Spectator | 95 WS
