Champagne AOC

The Comité Champagne dates domestic vines in Champagne to as early as the 1st century, and ties the region's royal image to Clovis' baptism at Notre-Dame Cathedral in Reims in 496, after which almost all the Kings of France were crowned there. Its history timeline marks 1668 for Dom Pierre Pérignon, a Benedictine monk at Hautvillers Abbey who was one of the first to see that different wines and different crus could complement each other, and who began to blend wines in a much more carefully considered manner. In the latter half of the 17th century Champagne developed a gentler pressing technique that separated the juice into fractions, allowing white wines to be made from black grapes. The Comité Champagne places the moment when making sparkling wine became a deliberate choice in the region between 1670 and 1720, with specific reference to "Champagne Wines" from the 1690s; cork stoppers arrived in 1685 and a thicker, more resistant Champagne bottle in 1770. The Comité Champagne explains that producers introduced the double fermentation known as the Méthode Champenoise, a primary fermentation in tanks followed by a secondary fermentation in bottle, to control the prise de mousse, and traces Champagne as it is known today to the period from the turn of the 18th to the end of the 19th centuries. Riddling racks (pupitres) were invented at the turn of the 19th century, in 1837 the Châlons-based pharmacist Jean-Baptiste François developed a reliable method for measuring the sugar to add for effervescence, and in 1884 Armand Walfard invented the cold disgorging method. Up to the end of the 19th century the Champagne wine-growing area extended over more than 60,000 hectares; grape phylloxera reached Europe in 1863, and in 1898 growers and houses founded the Champagne Viticultural Association (AVC) to replant on American rootstock. The legal scaffolding followed: an 1887 Angers Court of Appeal ruling reserved the term Champagne for wine produced in and sourced from the region, the production area was defined by a law passed in 1927, and the Champagne AOC was recognised on 29 June 1936. Decanter's Tim Hall notes that a 1908 boundary excluded the Côte des Bar, that a 1911 ruling restored the Aube only as a second-zone sub-region, and that it took the 1927 law to make the Côte des Bar properly Champagne. The Châlons Commission of 1935 brought houses and growers together to define production rules, and the Comité Interprofessionnel du Vin de Champagne (CIVC), established by the Law of 12 April 1941, followed on from it with more powers to defend and protect the region's wines.

The Comité Champagne places Reims at a latitude of 49°5 north and Épernay at 49°, and describes the vineyards as planted at the limits of their cold tolerance, under a dual climate with both oceanic and continental influences. The average annual temperature is 11°C, according to the Comité Champagne, while continental influences can bring winter temperatures below -10°C in places. Vines are planted at altitudes between 90 and 300 metres on mostly south-, south-east- and east-facing slopes, with an average gradient of 12 percent and some slopes as steep as 59 percent. The Comité Champagne describes the outcrops of sedimentary rock as 75 percent limestone, composed of chalk, marl and limestone proper, and notes that porous chalk acts as a reservoir storing 300 to 400 litres of water per cubic metre. By département, the Marne holds 66 percent of the area under vine, the Aube 23 percent and the Aisne 10 percent, with smaller areas in the Haute-Marne and Seine-et-Marne. The Montagne de Reims surrounds Reims like a half-moon, extending nearly 20 miles east to west and 3 to 6 miles wide, and Pinot Noir is its most common grape. In the Marne Valley, the area furthest east near Épernay is mainly planted with Pinot Noir, and Meunier becomes dominant moving westwards. The Côte des Blancs, named for Chardonnay, is 6 to 9 miles long, and its chalk cliffs are particularly well suited to Chardonnay, and the Comité Champagne notes that Chardonnay is mainly grown in the Côte des Blancs as well as the Côte de Sézanne. The Côte des Bar lies south-east of Troyes, where Pinot Noir makes up 83 percent of the vines; Decanter's Tim Hall (2022) describes it as some 130 km south of central Champagne on mostly Kimmeridgian clay-chalk marl like that of Chablis and Sancerre, with some 7,900 ha of vines and 64 of Champagne's 319 villages. Decanter's Giles Fallowfield places the 17 grand cru villages in three districts: nine in the Montagne de Reims, six in the Côte des Blancs, and Aÿ and Tours-sur-Marne in the Vallée de la Marne.

• Dual oceanic and continental climate; average annual temperature 11°C; Reims at 49°5 north and Épernay at 49° (Comité Champagne)
• Subsoil outcrops 75 percent limestone (chalk, marl, limestone proper); chalk stores 300 to 400 litres of water per cubic metre; vines between 90 and 300 metres altitude, average gradient 12 percent (Comité Champagne)
• Grand cru villages by district (Decanter): nine in the Montagne de Reims, six in the Côte des Blancs, two (Aÿ and Tours-sur-Marne) in the Vallée de la Marne; JancisRobinson.com names Aÿ, Bouzy and Sillery for black grapes and Avize, Cramant and Le Mesnil for Chardonnay
• Côte des Bar in the Aube: Pinot Noir 83 percent of vines (Comité Champagne); mostly Kimmeridgian clay-chalk marl, some 7,900 ha and 64 of 319 villages (Decanter, 2022); Decanter reports the Aube has never been allocated any grand cru or premier cru villages

Under the Méthode Champenoise, a primary fermentation in tanks turns the must into wine, and a second fermentation in bottle, the prise de mousse, makes the wine sparkling, as yeasts transform sugar into alcohol and carbon dioxide (Comité Champagne). JancisRobinson.com notes that lees contact has a perceptible effect on the wine after about 18 months and an even greater one after about five years. The law of 22 July 1927 determines which grape varieties may be used. Pinot Noir, at 38 percent of the area under vine, endows the wines with body, punch and structure and aromas of red fruits and flowers; Chardonnay, at 31 percent, brings freshness and floral, citrus and sometimes mineral notes and is an ideal grape for wines that age well; Meunier, at 31 percent, is less susceptible to frost because its bud burst happens later, and adds roundness and yellow-fruit aromas (Comité Champagne). Arbane, Petit Meslier, Chardonnay Rose, Pinot Blanc and Pinot Gris are also authorised and account for 0.3 percent of the area under vine; Chardonnay Rose was listed among the authorised varieties in 2025. Champagne AOC wines may only be produced from the fruit of third-leaf vines, and planting density averages roughly 8,000 plants per hectare. The Executive Board of the Comité Champagne sets the maximum yield each year within the European Union limit of 15,500 kg/ha. Non-vintage Champagne Brut is the most common Champagne and can blend several years, while a vintage Champagne is made solely from wines of one harvest and contains no reserve wines (Comité Champagne); JancisRobinson.com puts non-vintage at more than 80 percent of the region's output. A Blanc de Blancs is made exclusively from white grapes such as Chardonnay, a Blanc de Noirs exclusively from dark-skinned grapes such as Pinot Noir and/or Meunier, and a rosé either by maceration of black grapes, which may involve saignée, or by blending red Champagne wine into the white base wines, at around 5 to 20 percent. Under the regulations, non-vintage wines must age in the cellar for at least 15 months and vintage wines for at least 3 years from bottling, and in practice most producers extend this by a few years (Comité Champagne).

• Méthode Champenoise: primary fermentation in tanks, then a second fermentation in bottle, the prise de mousse, that makes the wine sparkling (Comité Champagne)
• Pinot Noir 38 percent (body, structure, red fruits), Chardonnay 31 percent (freshness, floral and citrus notes), Meunier 31 percent (roundness, later bud burst); five other authorised varieties account for 0.3 percent (Comité Champagne)
• Blanc de Blancs from white grapes only; Blanc de Noirs from dark-skinned grapes only; rosé by maceration or by blending in around 5 to 20 percent red Champagne wine (Comité Champagne)
• Minimum ageing from bottling: 15 months non-vintage, 3 years vintage (Comité Champagne); legal minimum on the lees 12 months non-vintage and three years vintage (JancisRobinson.com)

Champagne carries its own classification ladder on top of the appellation, built on the cru. A cru corresponds to a winegrowing municipality, and the Champagne vineyard area encompasses 319 crus across the five départements. The Comité Champagne records that a scale of crus, the Échelle des Crus, was officially established for the first time in 1911 following discussions between growers and houses, and over time gave each cru a percentage from 80 to 100 percent, which set the share of the basic grape price that cru received. The Decree of 1 July 1952 officially introduced the terms grand cru, exclusively for wines from municipalities with a 100 percent rating, and premier cru, exclusively for wines from municipalities with a 90 to 100 percent rating. In 2010 the INAO scrapped the Champagne cru scale, but agreed that municipalities having previously received a grand cru or premier cru designation could retain it. The two terms therefore survive on labels today as markers of cru identity. A second ladder sorts finished Champagne by sweetness, fixed at dosage, the final addition before corking of cane sugar dissolved in wine and known as the liqueur de dosage. A Champagne doux contains more than 50 grams of sugar per litre, a demi-sec between 32 and 50 grams per litre, a sec between 17 and 32 grams per litre, an extra dry between 12 and 17 grams per litre, and a brut less than 12 grams per litre. Where there is less than 3 grams of sugar per litre and no extra sugar is added, the wine is labelled brut nature.

• A cru is a winegrowing municipality; the Champagne vineyard area encompasses 319 crus across the five départements (Comité Champagne)
• Scale of crus first officially established in 1911, rating each cru from 80 to 100 percent of the basic grape price (Comité Champagne)
• Decree of 1 July 1952: grand cru for municipalities rated 100 percent, premier cru for those rated 90 to 100 percent; in 2010 the INAO scrapped the cru scale but let previously designated municipalities keep the terms (Comité Champagne)
• Dosage tiers by sugar per litre: brut nature under 3 g with no added sugar, brut under 12 g, extra dry 12 to 17 g, sec 17 to 32 g, demi-sec 32 to 50 g, doux over 50 g (Comité Champagne)

The Comité Champagne's key figures for 2025 count 16,460 growers, 120 cooperatives and 410 houses. A Négociant Manipulant (NM) buys grapes, musts or wines, in addition to any grapes from its own vines, to make Champagne on its own premises; a Récoltant Manipulant (RM) makes own-label Champagne from grapes exclusively sourced from its own vineyards; a Récoltant-Coopérateur (RC) delivers grapes to a cooperative and retrieves the musts or wines; and cooperatives that buy their members' grapes to produce wine under the cooperative's brand are known as Coopératives de manipulation (CM). Nearly 90 percent of the Champagne area under vine is owned and tended by growers, while the houses are responsible for more than two-thirds of sales and 90 percent of exports. The houses founded the Syndicat du commerce des vins de Champagne in 1882, now the Union des Maisons de Champagne (UMC), and the growers' Syndicat Général des Vignerons (SGV) was established in 1904; the two are the families represented within the Comité Champagne. Champagne houses first emerged in the 18th century, when names including Ruinart, Moët, Delamotte, Veuve Clicquot, Heidsieck and Jacquesson appeared. In 2025, the Comité Champagne reports 266.1 million bottles shipped, 191.9 million by Champagne houses and 74.2 million by cooperatives and growers, and 5.7 billion euros in revenues; by volume the top external markets were the United States (26.5 million bottles), the United Kingdom (22.7 million), Japan (13.3 million) and Germany (9.6 million). The UNESCO listing rests on three ensembles, the historic hillside vineyards in Mareuil-sur-Aÿ, Saint-Nicaise Hill in Reims and Avenue de Champagne in Épernay, and on the chalk cellars: former underground chalk quarries called crayères, of which the Comité Champagne counts 370 in Champagne, covering 25 km beneath the Saint-Nicaise hill in Reims, plus 110 km of cellars under Avenue de Champagne, kept at 10 to 12°C with 90 to 100 percent humidity (Comité Champagne). The region also makes still wines, most of them under the Coteaux Champenois appellation, and Rosé des Riceys is a local still pink speciality (JancisRobinson.com).
