At a time when most West Coast wineries have released their sauvignon blanc wines from 2012 and even in some cases 2013, it’s brave of Craig Camp, general manager of Napa Valley’s Cornerstone Cellars, to send not only review samples of the 2011, the winery’s current release, but the 2010 and ’09 as well. The implication is clear: These are meant as serious sauvignon blancs, 100 percent varietal, seasoned six months in mature French oak barrels and capable of aging as their counterparts in Bordeaux do, complex wines intended for, say, the richness of lobster, rather than the incisive brininess of oysters. The grapes derive from the Talcott Vineyard in St. Helena, a fact that perhaps accounts for the remarkable consistency in the character and quality of the three wines. Winemaker for Cornerstone is Jeff Keene.
The Cornerstone Cellars Sauvignon Blanc 2011, Napa Valley, is a pale gold color and offers beguiling aromas of lemongrass, honeysuckle and cucumber, woven with white peach, ginger and quince, with notes of fig and spicy oak. The wine is very dry, packed with elements of limestone and flint, and it exudes an intriguing earthy, almost briery quality; a few moments in the glass bring out hints of mango, lychee and roasted lemon. Most impressive are the wine’s tremendous polish and presence, its vibrancy and energy, all wrapped in a texture that’s both irreproachably crisp and enticingly soft and palatable. 14.1 percent alcohol. Drink now through 2017 to ’19. Production was 361 cases. Exceptional. About $30.
The Cornerstone Cellars Sauvignon Blanc 2010, Napa Valley, resembles its cousin from 2011 in its grapefruit-cucumber-lemongrass character, to which it adds notes of white pepper, sunny–dusty–leafy fig, lilac and licorice; a snap of black currant and vivid acidity animates the core. One feels the oak influence just a shade more in this 2010 than in the 2011, evinced in svelte suppleness and a dash more exotic woody spice. Again, though, the wine’s primary personality lies in its combination of substance and transparency, its heft and crystalline ethereal qualities. 13.9 percent alcohol; case production not available but certainly limited. Drink now through 2017 or ’18. Excellent. Sold at the winery for $50.
As with the 2011 and ’10, the Cornerstone cellars Sauvignon Blanc 2009, Napa Valley, offers a set of elements revolving around cucumber, lemongrass and grapefruit, lime peel, ginger and quince buoyed by powerful limestone and chalk elements. Perhaps the ’09 is a whisper less ripe and juicy, a hair more robust and structured than its stablemates, but at an age when many sauvignon blanc wines are lapsing into flatness and flaccidity, this one is wonderfully fresh and aromatic, vibrant and appealing. 13.9 percent alcohol; case production not available but certainly limited. Drink now through 2016 or ’17. Excellent. Sold at the winery for $70.
