Gosset Champagne in Ay calls itself the oldest Champagne domaine in France. It was founded by Pierre Gosset in 1584. The estate remained in the family for nearly 400 years but in 1994 was purchased by Cointreau. The estate makes a range of vintage and non-vintage Champagnes. Robert M. Parker Jr. has written that Cointreau “has continued the tradition of outstanding quality” at Gosset and that the Grand Reserve bottling offers the chance “to experience the complexity and technical polish that make Gosset a name with which to reckon.”
