Throughout the world there are many bubbly wines made after the style of Champagne, but only those made in that region in the north of France, according to the painstaking Méthode Champenoise, can rightfully be called Champagne. All others should be labeled as Sparkling Wine, and if they follow the same method it is called the Classic Method or a vernacular equivalent (i.e. Méthode Traditionnelle). Very inexpensive bubblies are mass-produced in departures from this technique.
