34,000 hectares, 319 municipalities, 5 departments: the wine-growing region of Champagne boasts a geography of astonishing precision, shaped by centuries of demarcation.

The production area of the Champagne appellation d'origine contrôlée (AOC), defined by law in 1927, covers some 34,000 hectares. This region, located in France some 150 kilometers east of Paris, comprises 319 crus (or communes) spread across five départements: Marne (67%), Aube (23%), Aisne (9%), Haute-Marne and Seine-et-Marne.
The Champagne vineyards are divided into four main regions: Montagne de Reims, Vallée de la Marne, Côte des Blancs and Côte des Bar. It comprises some 281,000 parcels, each with an average surface area of 12 ares. Historically, 17 villages have received the "grand cru" designation and 44 villages have received the "premier cru" designation. The three key elements of the Champagne terroir - climate, soil and subsoil, and relief - form a unique combination, a mosaic of micro-terroirs with unique characteristics. The expertise of Champagne's 15,000 winegrowers makes the most of these characteristics.
Champagne vineyards are planted between 90 and 300 meters above sea level. It is a hillside vineyard, mostly facing south, southeast and east, with an average slope of 12%, and some slopes reaching almost 60%. The Champagne terroir is sufficiently steep and undulating to allow good insolation of the vines, and its slope facilitates drainage of excess water.
