Caves Pommery, Ruinart, Veuve-Cliquot, Charles Heidsieck

The Champagne cellars are an underground network of galleries and chambers running beneath Saint-Nicaise Hill. The spaces feature vaulted ceilings and were carved from chalk to create perfect storage conditions for aging wine.

The move of Champagne houses underground began in the mid-18th century, with Ruinart first using the caves. The industry grew quickly as more houses discovered that the cool, stable conditions were ideal for production.

These cellars represent the heart of Champagne production and show how major houses built their operations here. The architecture and craftsmanship tell the story of an industry that has shaped daily life in Reims for centuries.

Temperatures underground remain consistent year-round, creating ideal storage conditions for wine. Visitors should know it stays cool below and sturdy footwear is recommended to navigate the narrow tunnels and stairs.

The underground maze is pierced by ventilation shafts drilled like inverted funnels into the chalk quarries. These shafts are often overlooked, but they are crucial for controlling the climate deep in the chambers.
