H. Lanvin & Fils produces this Brut Grand Cru Blanc de Blancs exclusively from Chardonnay sourced in the Côte des Blancs Grand Cru villages. The house highlights a chalky intensity and pronounced mineral character, typical of the region’s limestone soils. The cuvée is marketed as non‑vintage (NV) and is aged on the lees for an extended period (about 2,000 days).
