Responsible for the vast majority of American wine production, if California were a country, it would be the world’s fourth largest wine-producing nation. The state’s diverse terrain and microclimates allow for an incredible range of red wine styles, and unlike tradition-bound Europe, experimentation is more than welcome here. California wineries range from tiny, family-owned boutiques to massive corporations, and price and production are equally varied. Plenty of inexpensive bulk wine is made in the Central Valley area, while Napa Valley is responsible for some of the world’s most prestigious and expensive “cult” wines.
