Champagne
While the term Champagne is often casually used to describe any form of sparkling wine, it correctly can only be used in reference to the sparkling wine that comes from the Champagne region of France.

The method for producing this sparkling wine was first invented a monk, Dom Perignon. When this same process is used outside of the Champagne region for producing sparkling wine, the bottles will usually be labeled "Methode Champenoise", to indicate that they utilize the same methods and processes as the traditional French Champagne.
