Premiere Napa Valley (Corison Winery, Dyer Vineyard, Gallica, Snowden Vineyards)

Premiere Napa Valley is the annual barrel auction held by Napa Valley Vintners each spring, where participating wineries collaborate to produce one-of-a-kind lots sold exclusively at the live event — no commercial release follows. The In Concert Cabernet Sauvignon, produced by Corison Winery, Dyer Vineyard, Gallica, and Snowden Vineyards, exemplifies this model: four distinct Napa voices unified in a single blend. Corison contributes structured St. Helena Cabernet, Dyer adds Diamond Mountain concentration, Gallica brings Howell Mountain intensity, and Snowden draws from the Rutherford Bench. The 2017 vintage is the top performer in the database, a warm but balanced season delivering concentrated, structured Napa Cabernet. Secondary market prices range from $1 to $1,342, reflecting both lot format variation — some are full-barrel acquisitions, others individual bottles — and vintage premiums. The $206 average is consistent with collector-grade Napa Cabernet from non-household-name producers, and the $1,342 ceiling demonstrates that trophy-vintage In Concert lots attract serious bidder competition. The auction-only provenance creates inherent scarcity: no retail channel, no futures market, no winery allocation — only the original auction or secondary resale. This structural scarcity is the primary driver of auction premiums above retail equivalents from the same four estates.
