Bottlerock is a music festival that focuses primarily on indie rock and folk--two genres that are among the most popular in California. Comedy is also well-represented. Another big attraction of the event is, of course, the famed Napa wine--the festival is held in the Wine Country, after all. Besides that, Bottlerock works to cement Napa's image as a destination for foodies. The festival boasts a variety of food trucks as well as proximity to the downtown restaurants.
