The blend consists of 20% from each of the five Côte des Blanc crus of Cramant, Avize, Le Mesnil, Oger, and Vertus. The first four are grand crus, and Vertus is premier cru. According to cellar master Cyril Brun, each cru is chosen for its capacity to bring something unique to the blend. Cramant brings complexity and finesse, Oger a degree of opulence, Avize exotic fruit and minerality, Le Mesnil balance, and also mineral notes. Finally, Vertus, the only premier cru after the four grand crus, is selected for its freshness and texture.
