Sparkling wine can only be called Champagne if it comes from the region of Champagne, France. Strictly speaking, champagne means "French Champagne" coming from the Reims and Epernay districts east of Paris. California produces two types of sparkling wine. The bulk process type is basically glorified soda pop. The other, usually labeled methode champenoise or methode traditionelle, means the second fermentation process must take place in the same bottle it is served from. It is well worth the price to buy a sparkling wine using this method.
