Cornerstone Cellars

About

Cornerstone Cellars is a boutique California winery founded in 1991, with roots on Howell Mountain and wines sourced from Napa Valley, Sonoma County, and the Sta. Rita Hills. Led by winemaker Kari Auringer, the portfolio includes small-lot bottlings, sometimes no more than 100 cases. Tastings are offered at The Yount Room in downtown Yountville, with seasonal flights and optional culinary accompaniments.
