Beauté du Siècle Hennessy Cognac is a limited edition blend which comes in a Baccarat crystal bottle, housed in a special chest. It was blended by cellar master Yann Fillioux from Hennessy reserves which are up to 100 years old, the youngest being 47 years. The bottle's chest was made by 10 different artists using mirrored glass and melted aluminium. It opens with a bronze key and a concealed switch triggers the gentle rise of a tray holding the bottle, set in a gilded lattice designed by Guerlain. The Cognac was created in homage to a very special man, Killian Hennessy,' said Thibault le Mailloux, Hennessy communications director. Killian Hennessy, who is 100 years old this year, is the sixth generation descendant of the founder of Hennessy. He oversaw the merger between Hennessy and Moët & Chandon in 1971, and the creation of the LVMH group in 1987, of which he was the first honorary president.
