passage: Silver Oak Cellars
Silver Oak Cabernet Sauvignon is aged for about 25 months exclusively in American oak barrels. Silver Oak's Alexander Valley wines are aged in both new and once-used American oak barrels and spend an additional 14 months in bottle before release. Silver Oak's Napa Valley Cabernet Sauvignon is aged in only new American oak barrels and spends about 20 months in bottle after barrel. In answer to the question of why Silver Oak insists upon aging their wines in American oak barrels, Meyer once said, "I'm happy with a cellar of about 65 degrees. Aging is speeded up by heat and slowed down by cold, but the only thing I do to modify my cellar is drink it faster... To my palate, American oak imparts less wood tannin than French oak. I like tannic wine about as much as I like tough steak." The company formed a partnership with Missouri-based barrel producer A&K Cooperage in 2000 to have a steady supply of American oak barrels made to Silver Oak's specifications. In 2015, Silver Oak acquired A&K, becoming the first winery in the United States to own an American cooperage. Silver Oak now has full control of its barrel production, and have officially called it "The Oak Cooperage".
