Charles Heidsieck's prestige cuvée is a blend of pure Chardonnay from just five different Crus: Avize for verve and minerality; Cramant for complexity and ageability; Le Mesnil-sur-Oger for balance; Oger for creaminess and weight; and Vertus for floral freshness. An absolute masterpiece from the Côte des Blancs, this cuvée spends more than fifteen years maturing in the heart of Charles Heidsieck's two-thousand-year-old chalk cellars.
