Perrier-Jouët, owned by Pernod Ricard, has announced the launch of the world's most expensive champagne product. The company used the first day of spring, in keeping with the flower-themed Belle Epoque Perrier Jouët label, to publicise details of a limited edition 100-piece set with each case containing 12 bottles. Retailing at £40,000 a case, purchase of a tailor made champagne set will include a trip to the Maison Belle Epoque & an opportunity to meet the current cellar master Herves Deschamps. A bespoke liquer created by Deschamps will also be added to the champagne vintage. Olivier Cavil, Perrier-Jouët communications director, said: "Perrier-Jouet has always placed innovation, integrity & quality at the heart of its undertaking." Since the beginning, the House has worked with small volumes in limited production with a dedication to the art of champagne creation. The custom champagne personifies this philosophy."
