The prestige cuvée Blanc des Millénaires Vintage is made from Chardonnays from the Grand Crus and Premier Crus of the Côte des Blancs. The wines are vinified in oak barrels and aged for almost 15 years in the thousand-year-old chalk pits of the Maison Charles Heidsieck, from which the wine takes its name. This lively, mineral Champagne offers incomparable aromatic complexity and exceptional ageing potential (up to 30 years).
