More About 2020 Silver Oak Napa Valley Cabernet Sauvignon Silver Oak began in 1972 as a patriotic dream between two friends who wanted to vinify California Cabernet Sauvignon aged in American oak. More than a half-century later, their achievements remain a reference point for this recipe, producing age-worthy wines that are also delicious upon release. The winery maintains popularity by establishing itself as one of the US's most reliable and high-quality domestic Cabernet Sauvignon producers. However, now that they own their cooperage and make their barrels, their 2020 vintage takes quality to an even higher level. The Napa Valley Cabernet Sauvignon undergoes slight modifications based on each season's conditions before undergoing Silver Oak's distinctive aging process of two years in American oak. The winery allows the wines to mature for an extra two years in the bottle before making them available, and the Napa Valley 2020 vintage produced a wine characterized by concentrated intensity, impeccable balance, and refined flavors.
