The cave's ambiance is really neat... it's fun to explore the vineyard above the cave before or after your tasting and see where some of the grapes are grown and if you're an adventurous type, it's fun to take pictures by the giant Grape crusher statue on top of the vineyard. This is truly Napa's hidden gem! It's located at the Meritage Resort at the south end of Napa, and the tasting room is in a cave UNDER THE GRAPES. It's such a unique place to visit in Napa. The wines are excellent. The Mysterium is one of my favorite reds, and I love the Sauvingnon Blanc. The chardonnay is also very nice. The service in the wine cave is impeccable, and the employees are really knowledgable about the wine. They will also stay and have a friendly conversation with you if it's not too busy.
