Bollinger produces Champagne from the Aÿ Grand Cru in the heart of Champagne's premier terroir. The house works primarily with Pinot Noir, the region's signature dark fruit grape, alongside Chardonnay to craft wines of structure and depth. La Côte Aux Enfants, sourced from the storied Aÿ vineyard, stands as the flagship expression—a Pinot Noir-driven Grand Cru that has earned top marks from Wine Spectator, Decanter, Wine Enthusiast, Falstaff, and Wine Advocate. The R.D Extra Brut (Récemment Dégorgé), a blend of Pinot Noir and Chardonnay aged on its lees before late disgorging, represents the house's commitment to complexity and maturation. Both wines demonstrate the mineral precision and aging potential that define serious Champagne.
