Barceló Imperial Onyx is a blend of rums, aged for 10 years in ex-bourbon barrels with a "heavy char" grade (other premium rums are aged in barrels containing a "medium-light char" grade). Filtered though onyx stones, which give Barceló Imperial Onyx the mysticism that characterizes this rum of unprecedented intensity. It is uniquely different from other Dominican rums because it is made from the fermented juice of sugar cane and not from molasses. The result is a smoother, more well-rounded taste that showcases the true characteristics of the sugar cane.

The sugar cane that is the source for Barceló Imperial Onyx is estate grown in the Dominican Republic (versus other rum producers who source sugar cane or molasses on the open market). This commitment to quality ensures that only the best and most brilliant sugar cane goes into Barceló Imperial Onyx.
