The small Napa Valley Museum (55 Presidents Circle, Yountville, 707/944-0500, www.napavalleymuseum.org, Wed.–Mon. 10 a.m.–5 p.m., $4.50) sits tucked away behind Domaine Chandon on the other side of Highway 29 in Yountville. Here you’ll find perhaps the most complete description of the winemaking process available in all of Wine Country.

The main feature of the downstairs gallery is a big, high-tech, multimedia display that categorizes each step and month in the life of a wine (and a winemaker). If you’re interested in learning the details of the grape, plan on spending at least half an hour reading the left-hand wall. Next, you can test what you’ve learned with a variety of interactive “quizzes” on winemaking, and finally you can examine information about how different types of wine taste and how to eat and drink them.

A tiny exhibit tells the history of Napa Valley, from the earliest pioneers through the current wine boom. The upstairs gallery provides space for rotating exhibitions; you’re likely to find the work of local artists or art depicting food and wine.
