The Leopold Gourmel Hors d'Age Quintessence 30 Carats Cognacis a very old Cognac, strong and aromatic. The cognac is first matured for over 25 years in oak barrels, then a further 10 years in different casks. The taste and blend of this cognac hasn't changed since the 19th century. Distiller Gourmel says in his inimitable fashion that this cognac is truly, "a rare and selfish pleasure".
