More About 2019 Silver Oak Alexander Valley Cabernet Sauvignon Silver Oak's founders envisioned creating world-class Cabernet Sauvignon, aged exclusively in American oak, that could be cellared and enjoyed for decades. Founded in a dairy barn in 1972, Silver Oak has maintained a seductive house style from oak from their cooperage in Missouri and is now one of California's leaders in sustainability. The driving philosophy behind Silver Oak wines is that they have yet to make their best wine, and the vineyard team uses precise viticulture techniques to evaluate each vineyard block and make informed farming decisions on a block-by-block basis. The Alexander Valley Estate sits upon the benchland of the Mayacamas mountains, rich in mineral soils with excellent drainage key for Cabernet Sauvignon, which develops savory-like characteristics. Until 2011 and a 40-year tradition, Silver Oak Alexander Valley was 100% Cabernet Sauvignon, but blending experiments have since proven to enhance the wine, with the 2019 vintage seeing 95.2% Cabernet Sauvignon with Cabernet Franc, Merlot, and Petit Verdot, aged in an even 50-50 split of new and used oak barrels for complete integration.
