In 1870, Maurice Hennessy created Hennessy X.O for his circle of friends and introduced a new style of cognac. Hennessy X.O is the Original, the emblematic icon of the Hennessy Maison. Deep and powerful, the eaux-de-vie of this Hennessy X.O cognac are aged in young barrels and marked out by their power and energy, but also by their capacity to achieve a great roundness through time.
