Formerly known as
méthode champenoise or
méthode classique, champagne is produced by a traditional method. After primary
fermentation and bottling, a second alcoholic fermentation occurs in the bottle. This second fermentation is induced by adding several grams of yeast
Saccharomyces cerevisiae and rock sugar to the bottle – although each brand has its own secret recipe. According to the '
a minimum of fifteen months is required to completely develop all the flavour. For years where the harvest is exceptional, a ' is declared and some champagne will be made from and labelled as the products of a single vintage (
vintage champagne) rather than a blend of multiple years' harvests. This means that the champagne will be very good and has to mature for at least three years. During this time the champagne bottle is sealed with a
crown cap similar to that used on beer bottles. in the bottle forces out the ice containing the lees. Some wine from previous vintages and additional sugar ('''') is added to maintain the level within the bottle and adjust the sweetness of the finished wine. The bottle is then quickly corked to maintain the
carbon dioxide in solution. However, after the initial rush, these naturally occurring imperfections are typically too small to consistently act as nucleation points as the surface tension of the liquid smooths out these minute irregularities. The nucleation sites that act as a source for the ongoing effervescence are not natural imperfections in the glass, but actually occur where the glass has been etched by the manufacturer or the customer. This etching is typically done with acid, a laser, or a glass etching tool from a craft shop to provide nucleation sites for continuous bubble formation (note that not all glasses are etched in this way). In 1662 this method was developed in England, as records from the
Royal Society show.
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. As sparkling wine production increased in the early 18th century, cellar workers had to wear a heavy iron mask to prevent injury from spontaneously bursting bottles. The disturbance caused by one bottle exploding could cause a chain reaction, with it being routine for cellars to lose 20–90% of their bottles this way. 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".
Champagne producers There are more than one hundred champagne houses and 19,000 smaller '''' (vine-growing producers) in Champagne. These companies manage some 32,000 hectares of vineyards in the region. The type of champagne producer can be identified from the abbreviations followed by the official number on the bottle: •
NM: ''''. These companies (including the majority of the larger brands) buy grapes and make the wine •
CM: ''''. Cooperatives that make wines from the growers who are members, with all the grapes pooled together •
RM: ''''. (Also known as
Grower Champagne) A grower that also makes wine from its own grapes (a maximum of 5% of purchased grapes is permitted). Note that co-operative members who take their bottles to be disgorged at the co-op can now label themselves as RM instead of RC •
SR: ''''. An association of growers making a shared Champagne but who are not a co-operative •
RC: ''''. A co-operative member selling champagne produced by the co-operative under its own name and label •
MA: '
or '. A brand name unrelated to the producer or grower; the name is owned by someone else, for example a supermarket •
ND: ''''. A wine merchant selling under his own name
Marketing In the 19th century, champagne was produced and promoted to mark contemporary political events, such as the
Franco-Russian Alliance of 1893, and the
Tennis Court Oath to mark the centennial of
French Revolution, linking champagne to French nationalist ideology.
Négociants also managed to market champagne by identifying it with leisure activities and sporting events. They also successfully appealed to a broader range of consumers by highlighting the different qualities of sparkling wine versus ordinary wine, associating champagne brands with royalty and nobility, and selling off-brands under the names of importers from France at a lower cost. However, selling off-brands at a lower price proved to be unsuccessful, since "there was an assumption that cheap sparkling wine was not authentic." This strategy worked, and, by the turn of the 20th century, the majority of champagne drinkers were
middle class. In the 19th century, champagne producers made a concentrated effort to market their wine to women. This is done by having the sweeter champagne associates with female, whereas the dry champagne with male and foreign markets. In some advertisements, the champagne houses catered to political interest such as the labels that appeared on different brands on bottles commemorating the centennial anniversary of the
French Revolution of 1789. On some labels there were flattering images of
Marie Antoinette that appealed to the conservative factions of French citizens that viewed the former queen as a martyr. On other labels there were stirring images of Revolutionary scenes that appealed to the liberal left sentiments of French citizens. As World War I loomed, champagne houses put images of soldiers and countries' flags on their bottles, customizing the image for each country to which the wine was imported. During the
Dreyfus affair, one champagne house released a
champagne antijuif with antisemitic advertisements to take advantage of the wave of
Antisemitism that hit parts of France. Champagne is typically drunk during celebrations. For example, British Prime Minister
Tony Blair held a champagne reception to celebrate London winning the right to host the
2012 Summer Olympics. It is also used to
launch ships when a bottle is smashed over the hull during the ship's launch. If the bottle fails to break this is often thought to be bad luck. ==Wine districts, grape varieties and styles==
