Hennessy XO was created in 1870 by Hennessy for the personal use of Mr. Maurice Hennessy, his family and freinds. The 100 eaux-de-vie assembled to create X.O were aged for a long time – some for 30 years – to give an unparalleled robustness. Maurice Hennessy gave the name X.O to this extraordinary “extra old” cognac.
