An authentic, singular Champagne made exclusively from Chardonnay, a white grape with white juice. Although less widely known to the public than blended Champagnes, blancs de blancs (100% Chardonnay) are particularly sought-after by connoisseurs, who appreciate their delicate aromas as well as their vibrant freshness. "Brut Réserve" is a blend of two or three different years and contains at least 25% reserve wine.
