Champagne (; ) is a sparkling wine originated and produced in the Champagne wine region of France under the AOC rules of the appellation, which demand specific vineyard practices, sourcing of grapes exclusively from designated places within it, specific grape-pressing methods and secondary fermentation of the wine in the bottle to cause carbonation.

The grapes Pinot noir, Pinot meunier, and Chardonnay are used to produce almost all champagne, but small amounts of Pinot blanc, Pinot gris (called Fromenteau in Champagne), Arbane, Chardonnay rosé, and Petit Meslier are vinified as well.

Champagne became associated with royalty and luxury in the 17th, 18th, and 19th centuries. The leading manufacturers made efforts to associate their champagnes with nobility and royalty through advertising and packaging, which led to its popularity among the emerging middle class.

Origins

Still wines from the Champagne region were known before medieval times. The Romans were the first to plant vineyards in this area of northeast France, with the region being tentatively cultivated by the 5th century. Cultivation was initially slow due to the unpopular edict by Emperor Domitian that all colonial vines must be uprooted. When Emperor Probus, the son of a gardener, rescinded the edict, a temple to Bacchus was erected, and the region started to produce a light, fruity, red wine that contrasted with heavier Italian brews often fortified with resin and herbs.Coates, Clive. An Encyclopedia of the Wines and Domaines of France. University of California Press, 2000. pp. 539–40. Later, the Catholic church owned vineyards, and monks produced wine for use in the sacrament of the Eucharist. French kings were traditionally anointed in Reims, and champagne was served as part of coronation festivities. The Champenois were envious of the reputation of the wines made by their Burgundian neighbours to the south and sought to produce wines of equal acclaim. However, the northern climate of the region gave the Champenois a unique set of challenges in making red wine. At the far extremes of sustainable viticulture, the grapes would struggle to ripen fully and often would have bracing levels of acidity and low sugar levels. The wines would be lighter bodied and thinner than the Burgundy wines they sought to outdo.

Contrary to legend and popular assumption, Dom Pérignon did not invent sparkling wine, though he did make important contributions to the production and quality of both still and sparkling champagne wines.Christopher Merret Biographical Information. Royal Society website The oldest recorded sparkling wine is Blanquette de Limoux, which was invented by Benedictine monks in the Abbey of Saint-Hilaire, near Carcassonne, in 1531. They achieved this by bottling the wine before the initial fermentation had ended. Over a century later, the English scientist and physician Christopher Merret documented the addition of sugar to a finished wine to create a second fermentation six years before Dom Pérignon set foot in the Abbey of Hautvillers. Merret presented a paper at the Royal Society, in which he detailed what is now called , in 1662. Merret's discoveries coincided also with English glass-makers' technical developments that allowed bottles to be produced that could withstand the required internal pressures during secondary fermentation. French glass-makers at this time could not produce bottles of the required quality or strength. As early as 1663, the poet Samuel Butler referred to "brisk champagne".

In France, the first sparkling champagne was created accidentally; the pressure in the bottle led it to be called "the devil's wine" (), as bottles exploded or corks popped. At the time, bubbles were considered a fault. In 1844, Adolphe Jaquesson invented the muselet to prevent the corks from blowing out. Initial versions were difficult to apply and inconvenient to remove. Even when it was deliberately produced as a sparkling wine, champagne was for a very long time made by the , where 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 a dramatic 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 a record of 338.7 million bottles.

In the 19th century, champagne was noticeably sweeter than today's champagnes. The trend towards drier champagne began when Perrier-Jouët decided not to sweeten his 1846 vintage before exporting it to London. The designation Brut Champagne was created by Pommery for the British in 1876 (vintage 1874).

The only wines that are legally allowed to be named "Champagne" must be bottled within 100 miles of the Champagne region in France. The name is legally protected by European law and an 1891 treaty that requires true champagne to be produced in the Champagne region and made from the Pinot Meunier, Pinot Noir, or Chardonnay grapes grown in this region.

Rights to the name

The Champagne winemaking community, under the auspices of the (CIVC), has developed a comprehensive set of rules and regulations for all wine produced in the region to protect its economic interests. They include codification of the most suitable growing places, the most suitable grape types (most Champagne is a blend of up to three grape varieties, though other varieties are allowed), and a lengthy set of requirements specifying most aspects of viticulture. This includes pruning, vineyard yield, the degree of pressing, and the time that wine must remain on its lees before bottling. It can also limit the release of Champagne to market to maintain prices. Only when a wine meets these requirements may it be labelled Champagne. The rules agreed upon by the CIVC are submitted for the final approval of the (formerly the , INAO).

In 2007, the INAO, the government organization that controls wine appellations in France, was preparing to make the largest revision of the region's legal boundaries since 1927 in response to economic pressures. With soaring demand and limited production of grapes, Champagne houses say the rising price could produce a consumer backlash that would harm the industry for years into the future. That and political pressure from villages that wanted to be included in the expanded boundaries led to the move. Changes are subject to significant scientific review and are said not to impact Champagne-produced grapes until 2020. A final decision is not expected until 2023 or 2024.

Use of the word Champagne

Sparkling wines are produced worldwide, but many legal structures reserve the word Champagne exclusively for sparkling wines from the Champagne region, made in accordance with regulations. In the European Union and many other countries, the name Champagne is legally protected by the Madrid system under an 1891 treaty, which reserved it for the sparkling wine produced in the toponymous region and adhering to the standards defined for it as an ; the protection was reaffirmed in the Treaty of Versailles after World War I. Over 70 countries have adopted similar legal protection. Most recently Australia, Chile, Brazil, Canada and China passed laws or signed agreements with Europe that limit the use of the term "Champagne" to only those products produced in the Champagne region. The United States bans the use on all new U.S.-produced wine brands. However, those that had approval to use the term on labels before 2006 may continue to use it, provided the term is accompanied by the wine's actual origin (e.g., "California"). The majority of US-produced sparkling wines do not use the term Champagne on their labels, and some states, such as Oregon,Oregon State Law 471, including 471.030, 471.730 (1) & (5) ban producers in their states from using the term.

Several key U.S. wine regions, such as those in California (Napa, Sonoma Valley, Paso Robles), Oregon, and Walla Walla, Washington, came to consider the remaining semi-generic labels as harmful to their reputations (cf. Napa Declaration on Place).

Even the terms and Champagne method were forbidden by an EU court decision in 1994. the description most often used for sparkling wines using the second fermentation in the bottle process, but not from the Champagne region, is . Sparkling wines are produced worldwide, and many producers use special terms to define them: Spain uses Cava, Italy designates it , and South Africa uses . An Italian sparkling wine made from the Muscat grape uses the DOCG Asti and from the Glera grape the DOC Prosecco. In Germany, Sekt is a common sparkling wine. Other French wine regions cannot use the name Champagne: e.g., Burgundy and Alsace produce . In 2008, more than 3,000 bottles of sparkling wine produced in California labelled with the term "Champagne" were destroyed by Belgian government authorities.

Regardless of the legal requirements for labeling, extensive efforts by the Champagne region, and the use of alternative names by non-Champagne sparkling wine producers, some consumers, and wine sellers, including "Korbels California Champagne", use Champagne as a generic term for white sparkling wines, regardless of origin.

The village of Champagne, Switzerland, has traditionally made a still wine labelled as "Champagne": the earliest records of viticulture dated to 1657. In 1999, in an accord with the EU, the Swiss government conceded that, by 2004, the village would phase out the use of the name. Sales dropped from 110,000 bottles a year to 32,000 after the change. In April 2008, the villagers resolved to fight against the restriction following a Swiss open-air vote.

In the Soviet Union, all sparkling wines were called (, Russian for "that, which is of Champagne"). The name is still used today for some brands of sparkling wines produced in former Soviet republics, such as and . In 2021, Russia banned the use of the designation for imported sparkling wine, including sparkling wine produced in the Champagne wine region, reserving the designation for domestically produced sparkling wine only.

Production

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.

After aging, the bottle is manipulated, either manually or mechanically, in a process called (or "riddling" in English), so that the lees settle in the neck of the bottle. After chilling the bottles, the neck is frozen, and the cap removed. This process is called disgorgement. The pressure 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.
