The House of Jean Dumangin exploits 8.80 hectares of vineyards, 6 of which are listed as Premier Cru in the heart of the Montagne de Reims (Chigny-les-Roses area).
As it comprises a third of each grape-variety (chardonnay, pinot noir and meunier), the production of a whole range of different qualities is possible.
Since 1991, a 2.80 hectare plot grows on a hillside in the Couvrot vineyard area (near Vitry-le-François). As it is entirely planted with chardonnay, this chalky soil gives birth to the Brut Reserve Blanc de Blancs.
