About Cornerstone Cellars
Cornerstone Cellars is named for the cornerstone — the first stone laid in a masonry foundation, from which all other blocks are aligned and referenced. In architecture, it establishes the building's orientation and integrity; in winemaking, Cornerstone's naming declares the same foundational ambition: to produce Napa Valley Cabernet Sauvignon that is structurally sound, correctly aligned, and worthy of being built upon.
The Yountville tasting room is also home to Cornerstone Gardens — an installation of landscape architectural art pieces on the Washington Street property that makes it one of the most visually interesting wine destinations in Napa Valley, separate from the wines entirely.
The wine program produces Howell Mountain and Napa Valley Cabernet Sauvignon alongside Chardonnay and Rosé at accessible daily walk-in pricing that makes Cornerstone one of Yountville's most approachable wine stops on a day of culinary exploration.
