Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. The carbon dioxide may result from natural fermentation, either in a bottle, as with the ''traditional method'', in a large tank designed to withstand the pressures involved (as in the Charmat process), or as a result of carbon dioxide injection. Sparkling wine is usually white or rosé but there are many examples of red sparkling wines such as Italian Brachetto, Australian sparkling Shiraz and Azerbaijani "Pearl of Azerbaijan" made from Madrasa grape. The sweetness of sparkling wine can range from very dry "brut" styles to sweeter "doux" varieties.〔J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pg 656–660 Oxford University Press 2006 ISBN 0-19-860990-6〕 The classic example of a sparkling wine is Champagne, but this wine is exclusively produced in the Champagne region of France and many sparkling wines are produced in other countries and regions, such as Blanquette de Limoux in Southern France, Espumante in Portugal, Cava in Spain, Franciacorta, Trento DOC, Oltrepò Pavese Metodo Classico and Asti in Italy (the generic Italian term for sparkling wine being ''spumante'') and Cap Classique in South Africa. 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, Austrian, Czech and Slovak 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. ==History== Effervescence has been observed in wine throughout history and has been noted by Ancient Greek and Roman writers but the cause of this mysterious appearance of bubbles was not understood. Over time it has been attributed to phases of the moon as well as both good and evil spirits. The tendency of still wine from the Champagne region to lightly sparkle was noted in the Middle Ages but this was considered a wine fault and was disdained in early Champagne winemaking although it made the pride of other historic sparkling wine production areas like Limoux.〔T. Stevenson, ed. ''The Sotheby's Wine Encyclopedia (4th Edition)'' pg 169–178 Dorling Kindersley 2005 ISBN 0-7513-3740-4〕 Dom Pérignon was originally charged by his superiors at the Abbey of Hautvillers to get rid of the bubbles since the pressure in the bottles caused many of them to burst in the cellar.〔D. & P. Kladstrup ''Champagne'' pg 25 Harper Collins Publisher ISBN 0-06-073792-1〕 Later, when deliberate sparkling wine production increased in the early 18th century, cellar workers would still have to wear a heavy iron mask that resembled a baseball catcher's mask to prevent injury from spontaneously bursting bottles. The disturbance caused by one bottle's disintegration could cause a chain reaction, with it being routine for cellars to lose 20–90% of their bottles to instability. The mysterious circumstance surrounding the then unknown process of fermentation and carbonic gas caused some critics to call the sparkling creations "The Devil's Wine".〔name="Kladstrup pp 46–47">D. & P. Kladstrup ''Champagne'' pp 46–47 Harper Collins Publisher ISBN 0-06-073792-1〕 The British were the first to see the tendency of wines from Champagne to sparkle as a desirable trait and tried to understand why it produced bubbles. Wine was often transported to England in wooden wine barrels where merchant houses would then bottle the wine for sale. During the 17th century, English glass production used coal-fueled ovens and produced stronger, more durable glass bottles than the wood-fired French glass. The English also rediscovered the use of cork stoppers, once used by the Romans but forgotten for centuries after the fall of the Western Roman Empire. During the cold winters of the Champagne region, temperatures would drop so low that the fermentation process was prematurely halted—leaving some residual sugar and dormant yeast. When the wine was shipped to and bottled in England, the fermentation process would restart when the weather warmed and the cork-stoppered wine would begin to build pressure from carbon dioxide gas. When the wine was opened, it would be bubbly. In 1662, the English scientist Christopher Merret presented a paper detailing how the presence of sugar in a wine led to it eventually sparkling and that by adding sugar to a wine before bottling it, nearly any wine could be made to sparkle. This is one of the first known accounts of understanding the process of sparkling wine and even suggests that British merchants were producing "sparkling Champagne" before the French Champenois were deliberately making it.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sparkling wine」の詳細全文を読む スポンサード リンク
