Delphine Jelk, Guerlain Perfume Creation Director & Perfumer, and Renaud Fillioux de Gironde, HennessyÕs 8th generation Master Blender, have combined their know-how by celebrating the Houses' pioneering spirit with an unprecedented blending method never before seen at Guerlain, beautifully enhanced in Hennessy oak barrels. This new variation develops its characteristic notes in prolonged contact with wood. A meticulous blending process then follows to find the ideal balance between the fragrances from the two barrels, creating a singular composition.
