The Alexander Valley Silver Oak is 100% Cabernet Sauvignon which is a blend from several vineyards. It was blended and barreled down in 50% new and 50% once-used American oak. We blend prior to barrel aging to achieve balance of the natural elements such as fruit and tannin before they are influenced by oak. We age the wine for approximately 25 months to develop a harmony of the components. The wine received a further 15 months of bottle age before release.
