Nestled amidst the vineyards and rolling hills along the Livermore Valley, Concannon has been widely recognized for crafting full-flavored, complex and award-winning wines. Ocean air pours through the Golden Gate each afternoon cooling the influence of the sun, and enabling our grapes to develop both the ripe sugars and firm acids that fine wine demands.       We’re also perfectly positioned geologically, atop a 600-foot-deep bed of gravelly soil. All that rocks requires our vines to drive their roots deep into mineral-rich deposits, and it also keeps their grape and cluster size in moderation.       More than 140 of our 200 Livermore estate acres are Petite Sirah plantings grafted onto improved rootstocks. You'll see the Petite Sirah plantings right at the edge of the drive as you head into our classic tasting room.       Over the decades, we have carefully tuned our planting and trellising to take full advantage of this unique terroir. The result: intensely flavored, memorable wines vintage after vintage.
