Domain: Gosset Gosset, whose ancestors have lived in Aÿ since 1484, is one of the oldest houses in Champagne (created in 1584 by Jean Gosset). Béatrice Cointreau passed the domain over to her brother Jean-Pierre in 2007. Gosset's speciality has become vinous, intense and powerful champagnes which age majestically. This is particularly true for their brilliant vintage cuvées and the cuvée Célébris. The house launched a new cuvée in 2007, a blanc de blancs with remarkable tension.
