A number of regions worldwide are noted for their wine production. The unique environmental and social factors involved in a region's wine production are called Terroir by wine enthusiasts.
Because of this concept many wines associated with a region, especially wines that share a name with a region, are considered to only be true examples of that sort of wine if they originate there. For example, if one made "Champagne" on the moon, it would not be considered Champagne by many, and in many countries Champagne can only legally be called "Champagne" if it originated in the Champagne region of France.
