Cellar Master Émilien Érard curated the blend by selecting historic vintages—including the legendary 1945, 1955, and 1985 harvests—and integrating them with contemporary wines. By treating time as a primary ingredient, the House aims to capture the evolving depth of its cellar reserves. The visual presentation mirrors this focus on heritage: the bottle features a reinterpretation of the 1866 Champagne Cosmopolite label, originally designed to celebrate the founder’s early international expansion.

Production is strictly limited to 175 Jeroboam-sized units. Each 3-liter bottle will be available through select merchants this autumn at a retail price of $2,000. For the House, this release represents the culmination of its long-standing practice of extended aging within its two-thousand-year-old chalk cellars, solidifying a legacy that began in 1851.
