The Caldwell Tasting Experience…
We host a small number of private tasting experiences inside our 20,000-square-foot cave. Tastings last approximately 1.5 hours and usually include a half-dozen of our current release wines (alongside some tall tales and sometimes a few four-letter words). 

What’s It Cost?
Our tasting experiences start at $75 per person and are available by appointment, booked well in advance. Please contact our concierge at 707-255-1294 or for availability.


Ninety feet under the ground we built a working cave. We started digging in September 2002, and we moved in for harvest in 2005. It took a year and a half to dig, and the same amount of time to get it permitted with the county. Surrounded by volcanic ash, the cave has natural insulation that keeps us at about 59 degrees even on the hottest days. We have enough storage for 1,200 barrels (25,000 cases of wine), though we only make a few thousand cases every year.
