What's the difference between sparkling wine and Champagne?
How to Find Good Champagne/Sparkling Wine on a Budget
Champagne is sparkling wine or, in EU countries, legally only that sparkling wine which comes from the Champagne region of France. Where EU law applies, this alcoholic drink is produced from grapes grown in the Champagne region of France following rules that demand, among other things, secondary fermentation of the wine in the bottle to create carbonation, specific vineyard practices, sourcing of grapes exclusively from specific parcels in the Champagne appellation and specific pressing regimes unique to the region. Many people use the term Champagne as a generic term for sparkling wine but in some countries, it is illegal to label any product Champagne unless it both comes from the Champagne region and is produced under the rules of the appellation.
