The cellars are 50 metres underground, quarried deep in the heart of the famed Tonnerre stone, an enchanted, magical setting in which to watch over Bailly Lapierre Crémants as they age.

Located near the village of Saint-Bris-le-Vineux, not far from Auxerre in the Yonne valley, the ancestral wellspring of Bailly Lapierre since its very beginnings (in 1972) has been the ancient underground quarries, with subterranean galleries extending over more than 4 hectares (10 acres). They provide unique natural conditions that are ideal for the production of Crémants whose subtle effervescence makes them worthy of their name:
• a naturally cool temperature at a constant 12°C, ideal for maturing and ageing
• a naturally high level of moisture (about 80% humidity at the heart of the cellars)
• soft diffused light that helps preserve the flavour and colour of fine wines.
