The “coteaux, maisons et caves de Champagne”, consist of three areas:
- The historic vineyards of Hautvillers, Aÿ and Mareuil-sur-Aÿ
- Avenue de Champagne and Fort Chabrol in Epernay
- The hillside of Saint-Nicaise in Reims
An area made up of 320 communes.
These are the areas where the method for creating sparkling wines was developed, from its beginnings in the 17th century to its early stages of production in the 19th century.
