Centenario 30 rum is a blend of molasses rums aged using the Solera method (barrels placed in a pyramid shape, where the oldest rums educate the youngest). The final blended rums range in age from 8 to 30 years. These Costa Rican rums are aged in American oak barrels before being bottled in a superb decanter, worthy of this rum's high-end status. The decanter also features some of the medals won by this Centenario 30 at various international competitions.
