Editorial profile

Concannon Vineyard has farmed the Livermore Valley since 1883, when Irish immigrant James Concannon chose the region over Napa for its resemblance to Bordeaux's gravelly terroir. The winery survived Prohibition under James's son Joe, and in 1961 fourth-generation winemaker Jim Concannon released the first wine in the U.S. varietally labeled as Petite Sirah, a grape the estate had previously used only for blending.

James Concannon's original Cabernet Sauvignon cuttings, imported from Château Margaux, were later selected by UC Davis into the "Concannon Clones" 7, 8 and 11, which the winery says now underlie an estimated 80% of California's planted Cabernet Sauvignon. The Conservancy tier draws exclusively from Livermore vineyards protected under a local land-conservation trust. Both concannonvineyard.com and concannon.wine answer automated requests with a bot-detection challenge rather than serving the page, so this profile and the wines below are drawn from Internet Archive captures of the producer's site and online shop.
