With 480,000 vineyard acres and 1200+ wineries producing 560 million gallons of wine annually, California is only exceeded by the national outputs of Italy, France, and Spain. California, used as an appellation, can only be a guarantee of broadest-origin (and nothing more), and wines carrying the California appellation are likely to be blends of fruit originating from a number of more specific (and distinct) appellations within the state.
