Perhaps the most helpful, most friendly of all sparkling tasting rooms we visited in the area. Rather than tether you to a bar, you're able to get service at a table. Just look at the menu selection, and someone will be with you shortly. Mumm Napa is the best place to stop by at the end of the day. The reason being is that they have outdoor seating overlooking their vineyards. It's a special winery because they have a variety of sparkling wines. Don't fret, if it's hot (just like it was yesterday at 94 degrees) they turn on their mist sprays and instantly you are cooled down. They have 3 pour flights plus the full glass. It's located on the Silvarado Trail so this gives you a chance to take a peek on what this trail has to offer.
