The occupation began almost immediately after France fell in June 1940. German Weinführer Otto Klaebisch arrived in Épernay with specific orders: control champagne production, requisition the best bottles for the Reich, and prevent any wine from reaching Allied hands. What he didn't anticipate was how the region's thousand-year-old chalk tunnels would become the backbone of French resistance. When Count Robert-Jean de Vogüé of Moët & Chandon refused to hand over his cellar keys, he was arrested and sent to a concentration camp. But the keys had already been passed to cellar masters who knew every tunnel by heart.

Radio operators broadcast from Veuve Clicquot's deepest cellars while coded messages were hidden in shipping manifests for neutral countries.
The chalk tunnels, dug by Romans and expanded for centuries, created a perfect underground city. German patrols couldn't monitor every entrance, and the constant 50°F temperature meant radio equipment functioned reliably.
Houses like Krug and Bollinger buried their best vintages deeper in the chalk, replacing visible stocks with lesser bottles. Meanwhile, champagne became underground currency — traded for safe passage, information, and supplies from sympathetic locals.
A bottle of Dom Pérignon could buy forged papers or a week's worth of food. The Germans knew champagne's value but couldn't distinguish between a 1928 vintage and a rushed wartime blend in the dim cellar light.
Master blenders like Jacques Bollinger secretly documented their techniques and grape sources, hiding records in sealed bottles buried in remote corners of the cellars. Some caves held not just wine but entire libraries of viticultural knowledge.
When the war ended, Champagne could resume production immediately because the techniques, blend formulas, and supplier relationships had been preserved underground. Other wine regions took years to recover their pre-war quality.
Picture being forty feet underground in absolute darkness, feeling your way along chalk walls worn smooth by centuries of hands, while above you German boots echo on cobblestones. The only light comes from candles that must be extinguished the moment footsteps approach. Your breath fogs in the constant chill, and the silence is broken only by the distant sound of bottles being carefully moved, one by one, deeper into the maze.
When you taste older champagne today — particularly bottles from houses like Pol Roger or Bollinger — you're drinking wine that survived one of history's darkest periods. Some bottles in current releases contain reserve wines that spent the war years hidden in those chalk tunnels. The minerality you taste isn't just from the terroir; it carries the weight of survival, resistance, and the determination of people who risked everything to preserve their craft.
