Its vineyards are located in the Vallée de la Marne subregion of Champagne, and are classified as Premier Cru (99%) in the Champagne vineyard classification. Together with Tauxières-Mutry it is the highest rated of the Premier Cru villages, and has therefore just missed out on Grand Cru (100%) status.
