Fierve Verte Eau de Parfum 50mlKilian Hennessy's Inspiration: Inspired by the city of Paris, KILIAN PARIS presents Fivre Verte by KILIAN, a hymn to a legendary Parisian liquor: absinthe. The perfume expresses the traditional French Happy Hour, that early evening window of time when absinthe was served upon sugar into a glass and swirled with a spoon in a slow paced ritual in which the liquid turns pastel green.
