The Mailly Grand Cru estate extends across 80 hectares, entirely located in the Grand Cru village of Mailly Champagne, at the heart of the Montagne de Reims nature park. The vineyard is divided into 35 "Lieux-Dits", planted to the two noble Champagne varietals, the Pinot Noir (75%) and the Chardonnay (25%). Blessed with a unique terroir, the vineyard is distinguished by a location that faces all four points of the compass. Most of the plots are north-facing, favouring subtle, well-balanced wines. This is where Mailly Grand Cru Champagne is made, exclusively from Mailly Champagne grapes. The vines today are lovingly tended by some 25 families, all descended from that handful of men who together established this estate and resolved to prove the magnificent potential of the Mailly terroir.

Champagne MAILLY Grand Cru has always placed people and the preservation of of its natural haritage in the heart of its economic development. The company is B CORP Certified since 2025.
