Clear tulip-shaped glass, marked "El Dorado Rum" on the front. El Dorado's flavor and taste is much due to the tropical climate of the lush country of Guyana - which translates from its Amerindian name “Land of many waters” - and the three centuries of rum production along the banks of the Demerara river. Quality Demerara rum is used as a crucial component in many Tiki cocktails and El Dorado has a good reputation for quality Demerara rum.
