MEZAN JAMAICAN RUM XO. The Jamaica Rum is a blend of rums from several distilleries. This blend allows the two styles of distillation to come into play. The floral aromas from the column still marry with the higher richness and ester content of the pot still rums. Each unique batch of Mezan Jamaica XO is re-casked for a certain amount of time before being bottled. This encourages the flavours to melt and to improve the rum’s structure and subtlety. Mezan Jamaican is pungent and generous with aromas of fresh banana and sweet spices typical of great Jamaican rums.
