The highest quality Cognac on the market today, Louis XIII has been carefully tended by three generations of Rmy Martin cellar masters. The result is a magical combination of savoir-faire, art and patience. Rmy Martin Louis XIII uses only grapes from the Grande Champagne region which guarantees its unique, exclusive quality. It is blended from eaux de vie, some more than a century in age, then it is aged in ''tiercons'', barrels that are several hundred years old.
