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 temperatures prematurely halted fermentation in the cellars, leaving dormant yeast cells that would awaken in the warmth of spring and start fermenting again. One of the byproducts of fermentation is the release of carbon dioxide gas, which, if the wine is bottled, is trapped inside the wine, causing intense pressure. The pressure inside the weak, early French wine bottles often caused the bottles to explode, creating havoc in the cellars. If the bottle survived, the wine was found to contain bubbles, something that the early Champenois were horrified to see, considering it a fault. As late as the 17th century,
