Davidoff – XO is a finely crafted Cognac that has aged for at least 10 years in casks made from Limousin oak. It is produced for Davidoff, the well-known Swiss cigar company. The Cognac was previously produced by Hennessy, a famous, centuries-old Cognac house, but the rights of production were sold to Hine. Similarly famous, Hine was established in 1763 and is the only cognac producer in the world to have a UK Royal Warrant.
