Champagne the wine was bottled before the initial fermentation had finished. Champagne did not use the "" until the 19th century, about 200 years after Merret documented the process. The 19th century saw an exponential growth in Champagne production, going from a regional production of 300,000 bottles a year in 1800 to 20 million bottles in 1850. In 2007, Champagne sales hit an all-time record of 338.7 million bottles. In the 19th century Champagne was noticeably sweeter than the Champagnes of today. The trend towards drier Champagne began when Perrier-Jouët decided not to sweeten his 1846 vintage before exporting it to
History of Champagne sparkled because it was sealed in a bottle before fermentation was complete. He further noted that it was the sugar in the wine that facilitated this fermentation process resulting in bubbles. Along with the bubbles came intense pressure from the carbon dioxide gas that could result in the bottles exploding. 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 British method of coal fired glassmaking contributed to stronger wine bottles being available that could withstand the pressure of the carbon dioxide gas
