An appellation is a geographical area recognized for a distinctive combination of soil, climate, and identifiable regional wine character. The word appellation comes from the French Appellation d'Origine Controlee laws, which are laws meant to ensure quality within specific regions of France. These same principles have been used to create American Viticultural Areas (AVA) in the United States.
