Rum Bumbu XO. Bumbu XO is truly a thing of beauty. A smooth, rich and complex rum created from scratch by our master distiller, our XO is aged in bourbon barrels and selectively finished in white oak sherry casks to achieve a beautifully balanced, endlessly sippable rum. This special release is distilled and aged in Panama, where we created a truly unique and unquestionably superior rum. Aromas of toffee, toasted oak, and vanilla give way to orange zest, peppery spice and even a hint of coffee on the palate. A wonderfully engaging rum that encourages repeat visits, Bumbu XO is perfect for traditional rum cocktails and perhaps even better on its own, neat or with a single ice cube.
