Like a lot of grand adventures, the Cornerstone story starts with a conversation between friends over a glass of wine. The result was Cornerstone Cellars, and three decades later, the winery is making wines with constancy and classic varietal attributes that manage to be distinctively approachable and delicious. Their DNA combines old-school Napa Valley ease with a welcoming Southern approach to entertaining, and the result is classic Napa wines that make any table and any dinner a little more welcoming and celebratory.

When you visit, you’ll walk into a tasting room that doubles as a gallery space, with thoughtful art on the walls and a carefully curated soundtrack playing in the background. The whole setup encourages lingering—you’re not rushed through your tastes, and the staff actually wants to talk about the wines rather than move you along to the next group. The energy feels genuinely relaxed for a Yountville tasting room, which can sometimes feel a bit formal.

Dogs are absolutely welcome here, and the setup actually works well for them. You’ll be seated on the patio, which means your dog gets to be part of the experience without being stuck inside an air-conditioned room. They provide water bowls without you having to ask, and the patio has enough shade that it’s comfortable even during warmer months. The space isn’t cramped, so there’s room for your dog to settle in while you’re working through the flight.

The wines themselves lean toward what works best in Napa—Cabernet Sauvignon, Merlot, Chardonnay—and they’re made to actually drink rather than collect. Prices are fair for the area, and the overall vibe is unpretentious. If you’re coming through Yountville and want a tasting experience that feels genuinely welcoming rather than intimidating, Cornerstone delivers. Bring your dog and plan to spend a couple hours here rather than rushing through.
