Dom Pérignon's Secret
28 kilometers of caves, a vanished recipe
📱 1 to 10 phones · 1 team per phone · Independent codes
Beneath the Avenue de Champagne in Épernay, 28 kilometers of caves carved into chalk hold millions of bottles. Dom Pérignon's original recipe — the monk who perfected champagne — is said to be hidden somewhere in this underground labyrinth.
Beneath the richest avenue in the world, a monk hid his formula
The Avenue de Champagne is often considered the richest street in the world — not for its buildings, but for what lies beneath. Tens of millions of bottles age in 28 km of galleries carved into Champagne chalk. Dom Pérignon, a Benedictine monk at the Abbey of Hautvillers, perfected the art of blending in the 17th century. His notes, recorded in an abbey register, vanished during the Revolution. Legend has it they are somewhere in the caves.
« "Come quickly, brothers, I am drinking stars!" »— — Attributed to Dom Pérignon, 17th century
Dom Pérignon — the monk who drank stars
Dom Pierre Pérignon (1638-1715) was cellarer of the Abbey of Hautvillers for 47 years. Contrary to legend, he did not invent champagne — the bubbles already existed. But he perfected the art of blending grape varieties, improved pressing techniques, and developed the use of cork stoppers to maintain effervescence.
His winemaking registers, meticulously kept for nearly half a century, constituted a unique treasure of expertise. After his death, the monks continued to use them. During the Revolution, when the abbey was closed and its property dispersed, the registers disappeared. Some were found in local archives. The most important — containing the secret blending formulas — remains missing.
The Avenue de Champagne in Épernay, built in the 19th century, unites the greatest houses: Moët & Chandon, Perrier-Jouët, Pol Roger. Beneath their bourgeois facades, the caves extend for kilometers. In 2015, the "Champagne Hillsides, Houses and Cellars" were listed as UNESCO World Heritage.
