Updated October 2026.
In brief. Champagne grapes may be grown in 319 communes across five French départements, inside a plot-by-plot boundary drawn from 1908 onwards and fixed in law in 1927. A review launched in 2003 would have added around forty communes. On 21 October 2026 the growers' union that manages the appellation asked for that review to be stopped. The boundary in force does not change.
Whether a plot lies inside the delimited area is the first question in any Champagne vineyard purchase. It alone separates the value of farmland from the value of a vineyard. This page sets out how the boundary was built, what the review was meant to do, and what the October 2026 decision leaves in place.
How was the Champagne area first drawn?
Delimitation came almost thirty years before the protected appellation. A French law of 5 August 1908 allowed wine areas to be drawn according to local usage, and a decree of 17 December 1908 defined a first “Champagne viticole”, covering the Marne and part of the Aisne. The Aube was left out, which led to serious unrest in the vineyards in 1911.
The lasting settlement is the law of 22 July 1927. It defines the Champagne area in three parts: the territory of the 1908 decree; communes of the former province of Champagne and county of Bar-sur-Seine that had declared a harvest between 1919 and 1924; and three named communes in the Aube. It also set a rule of precedence, under which only land under vine, or used for vines before phylloxera, could qualify, and required the eligible land to be listed commune by commune, by cadastral reference. That is the origin of the plot-level boundary.
The appellation d'origine contrôlée itself was recognised by a decree of 29 June 1936, which created no new area: it referred back to the 1927 law. The current product specification, approved by decree no. 2010-1441 of 22 November 2010, still does the same.
What does the area cover today?
Grapes for Champagne can be grown in 319 communes: 212 in the Marne, 63 in the Aube, 39 in the Aisne, 3 in the Seine-et-Marne and 2 in the Haute-Marne. Wine can be made in a wider area of 635 communes. The Comité Champagne counts 34,200 hectares of vineyard (2023 data). No official source consulted publishes the total area classified for the appellation, as distinct from the area actually planted.
What was the 2003 review?
In July 2003 the Syndicat général des vignerons de la Champagne, the body that manages the appellation, asked the French appellations authority, INAO, to review the area. INAO approved a draft in March 2008 that would have taken the production area from 319 to 357 communes, removing two. After objections were heard, the communal area approved in 2011 stood at 362 communes, and plot-by-plot surveys began in 2013. By mid-2016, 126 communes had been surveyed. The product specification was never amended: the enlarged area remained a project.
Why was the review paused, then stopped?
In February 2025 the growers' union asked INAO to suspend the work. Under EU planting rules in force since 2016, Champagne had to accept 10 ares a year of new vines for wines without a geographical indication inside its appellation area, and the union was unwilling to redraw the boundary without control over new planting. Regulation (EU) 2026/471 of 24 February 2026, the EU “wine package”, now lets member states limit or refuse new planting authorisations in defined areas, including for wines without a geographical indication. No French measure applying it to Champagne had been published at the date of this update.
On 21 October 2026, meeting in Épernay, the union's board voted in favour of stopping the review altogether. Its press release gives two reasons. The climate has changed: between 1996–2005 and 2016–2025, average temperature rose by about one degree, in the air and in the soil, and the criteria used to classify plots describe conditions that no longer hold. And the market has changed: exports rose from 41% of shipments in 2003 to 58% in 2025. The union says the decision does not question the 2003 choice or INAO's work. Formally it is a request; INAO, which runs the procedure, has to act on it.
What does it mean for vineyard land?
- The boundary in force is unchanged. A classified plot stays classified; an unclassified one gains nothing.
- Communes named in the 2008 draft acquired no rights. Land there remains farmland in law.
- Deals priced on a future classification lose their basis. Land bought in expectation of entry into the area, and price adjustment clauses tied to it, need to be reread.
- Scarcity is confirmed. Without an extension, the supply of appellation vineyard stays where it is. Price bands are set out in Champagne vineyard prices.

Frequently asked questions
How many communes are in the Champagne appellation?
319 communes for growing the grapes, across the Marne, Aube, Aisne, Seine-et-Marne and Haute-Marne, and 635 communes for making the wine, according to INAO.
Is the Champagne appellation area being enlarged?
No. A review launched in 2003 would have added around forty communes, but on 21 October 2026 the growers' union that manages the appellation asked for it to be stopped. The boundary in force is unchanged.
Which law defines the Champagne area?
The law of 22 July 1927, which rewrote article 17 of the law of 6 May 1919. The product specification approved in 2010 refers to it, and the plot-level boundary results from INAO decisions.
Can new vineyards be planted in Champagne?
Only on classified land, with a planting authorisation under the EU scheme in force since 2016. Since February 2026, EU rules allow France to limit or refuse new authorisations in defined areas.
