Cornerstone Cellars

 In 1991 Michael Dragutsky embarked on a quest to deliver on the potential he saw in a select few of   Napa Valley’s finest mountain and benchland Cabernet Sauvignon vineyards.   Since that time, our signature winemaking style of firm structure and nuanced   texture have attracted an ever-growing number of Cornerstone Cellars admirers   while remaining true to Napa’s robust, delicious wine profile on the world  wine stage.

Twenty-six years in, the next generation of Cornerstone Cellars sales and winemaking teams bring to market a diverse portfolio of Cabernet Sauvignon wines –of which each one delivers a focused flavor profile - with realistic pricing to match. Now more than ever, we are resolved to implement a long-term brand development strategy and to constantly renew our commitment to that original winemaking ideology and style.
