About Us / Cornerstone Cellars History: For twenty vintages Cornerstone Cellars has been crafting classic, collectable Napa Valley Cabernet Sauvignon. We produce two distinctive Cabernets, our signature single vineyard Howell Mountain and our Napa Valley, which is created by intertwining the personalities of four outstanding vineyards. More than two thirds of our cabernet sauvignon vineyards are certified organic. Both of our Cabernets reflect the character of our vineyards and will age beautifully. Our Cornerstone Cabernet is complimented by our Cornerstone Cellars Sauvignon Blanc, from dry-farmed old vines in St. Helena.
