Champagne was the first region in the world to start producing sparkling wine on a commercial level and where most New World producers look to for inspiration. Producing a fizzy wine often occurred by accident, and was, for a long time seen as a detriment with producers going to great lengths to prevent a second fermentation. Due to the marginal climate the temperature in the fall would often dip, sedating the yeasts before all the sugars were converted into alcohol. When the region warmed up the following spring the unfermented sugars occasionally spurred on a second fermentation trapping the carbon dioxide (a by-product) in the bottle . It wasn’t until the turn of the 19th century that sparkling wine became popular and desirable. The region is split into four regions. Three are adjoining: The Montagne de Rheims to the north, the Cotes de Blanc to the south, and the Marne Valley in between. The fourth and separate region is the Cote des Bar in the Aube valley, some 70 miles south of Epernay.
Sparkling wine is a wine with high levels of carbon dioxide in it making it bubble. The carbon dioxide is a result of natural fermentation, either in a bottle or a specially designed tank, or as a result of carbon dioxide injection.Sparkling wine is usually white or rosé but there are many examples of red sparkling wines. The sweetness of sparkling wine can range from very dry "brut" styles to sweeter "doux" varieties.When one thinks of sparkling wine they usually think of Champagne, but this wine is exclusively produced in the Champagne region of France and many sparkling wines are produced in other countries and regions. Most countries reserve the word Champagne for a specific type from the Champagne region of France. The French terms "Mousseux" or "Crémant" are used to refer to sparkling wine not made in the Champagne region. German and Austrian sparkling wines are called Sekt. The United States is a significant producer of sparkling wine with producers in numerous states. Recently the United Kingdom, which produced some of the earliest examples of sparkling wine, has started producing sparkling wines again.
