Created by Maurice Hennessy in 1870 for his circle of friends, X.O was first produced at a turning point in history and introduced a new style of cognac: bold, rich and complex. The 100 eaux-de-vie assembled to create X.O were aged for a long time – from 10 to 30 years – to give unparalleled robustness. Maurice Hennessy gave the name X.O to this extraordinary “Extra Old” cognac.
