The first X.O since 1870. Woody, spicy, vanilla, matured fruits, structured, cinnamon. Hennessy X.O is a blend of around one hundred "eaux-de-vie" from Cognac's finest growing regions, carefully matured in our cellars.Hennessy X.O can be served neat, but is also often enjoyed "on the rocks": a great tasting experience. "When I add ice to my X.O, this immediately releases the subtle flavors and aromas of this magnificient cognac", says Mr. Gilles Hennessy, 7th generation of the legendary Cognac family.
