Cornerstone Cellars

Boutique California Wines
Since 1991

Discover Napa Valley’s Best Wines

Texture. Elegance. Expressiveness. Cornerstone Cellars’ portfolio conveys the type of wines we enjoy and the wines we like to share. Our story started – and continues – with Howell Mountain but along the journey we’ve developed and treasured long standing friendships with growers in Oakville, Rutherford and Calistoga, just to name a few. Our wines are bottled in small lots, sometimes no more than 100 cases. Be a part of our journey and discover the fruits of our passion.

About Cornerstone cellars

It all started with a group of friends sharing a bottle of Cabernet Sauvignon around a picnic table on the hillsides of Howell Mountain. From what could have been a passing moment of inspiration has resulted in 30 years of small-production wine making focused on some of the most celebrated regions and vineyards in Napa Valley, Sonoma County and the Sta. Rita Hills. Led by Winemaker Kari Auringer for the past decade and half, Cornerstone Cellars is driven to share wines that are elegant, full of life and are representative of the growing sites she has selected.

Explore Our Wine Clubs

Every wine has its own role and its own unique character. At Cornerstone Cellars, we think that should be true of wine clubs, too. That’s why Cornerstone Cellars offers a trio of wine clubs, each one suited to a different approach to enjoying our wines. What all three have in common is delicious wines hand selected by our winemakers, perfect to enjoy right now. Joining one of our clubs is a great way to always have some of our best wines on hand for some spontaneous entertaining.
