Niebaum-Coppola was the second winery we visited. It offers a tour (costing about $25), but we opted not to take it. Nevertheless, you can enjoy most of the fantastic facilities, minus a tour of the cellars and through the vineyards, on your own at no charge.
The winery is a beautiful castle-like structure that was purchased by Francis Ford Coppola, along, of course, with the vineyards. Unique to NC is the movie memorabilia, including props from The Godfather, Dracula, and Tucker, and artifacts from early movie-making. Coppola's Oscars are also on display, as well as items relating to the history of the winery before it belonged to Coppola. There is an opportunity to sample (for a charge) the products of Coppola's vineyards and plenty of outdoor seating.
