Legend has it, the pirates of old stored their high proof rum in charred oak casks in order to give it a smooth mellow taste.Today this tradition lives on in Captain Morgan ® Black Cask™ 100 Proof Spiced Rum, a secret blend of Caribbean rums and select spices which brings out the intensity of rum in all its original full-flavored glory.A firm favourite with the Captain, it's specially crafted to taste great with cola or as a shot.
