A geographical area that's part of a country or state yet less specific than a district. In France, for example, Bordeaux is considered a wine region and Graves, which is within Bordeaux, is referred to as a district. Each region typically specializes in grape varietals that grow well there due to the unique climate and soil. FYI, wines whose labels list only a region, such as Burgundy, rather than a specific district or appellation within that region, such as Nuits-St-Georges, tend to cost less since they are less exclusive. It's like asking for ice cream instead of Häagen-Dazs.
