Jarvis Winery

Return to Hwy 29 and cross it onto Trancas, which after 1½ miles becomes Hwy 121 (signposted for Lake Berryessa). Follow this road for 4 miles as it climbs into the wooded hills. Watch for a gate on the left marking the Jarvis Winery entrance (2970 Monticello Road, Napa, CA 94559). The gates automatically open after you give your name and tour information (book well in advance—tour groups are limited to a very small number). The tour is fun and the structure of the Jarvis Winery is different from that of any other you will see on this itinerary. It also produces excellent wines (Cabernet Franc, Cabernet Sauvignon, Chardonnay, and Merlot). All you see as you approach are two massive doors built into the hillside—it looks like an entrance into a bunker. But inside, another world opens up as you find yourself in a giant cave. You follow a path that forms a loop around the cavern, passing by an underground stream and a waterfall, and visit the Crystal Chamber, a grand reception hall. At the conclusion of the tour you sample fine wines at a small table surrounded by gilded chairs with blue velvet upholstery. Tours are offered at 10 am and 1:30 pm. Based on demand, extra tours are sometimes added. 707-255-5280 or 800-255-5280, www.jarviswines.com.
