Bacardi, the largest privately-held spirits company in the world, has expanded its portfolio of super-premium rums with the acquisition of Banks Rum.

Terms of the transaction were not disclosed.

The Banks portfolio includes the brand’s 5-Island Rum, 7 Golden Age Blend and various limited editions.

Banks rum is currently available in some of the most influential on-premise establishments, according to the company, including in the United States, Germany, United Kingdom, France, Japan, Portugal, Russia, Switzerland, Denmark and Singapore.

Created by Founder and Master Blender Arnaud de Trabuc, and inspired by the travels and discoveries of legendary 18th-century British explorer and botanist Sir Joseph Banks, Banks is blended according to a secret formula developed by blending rums from up to seven different origins, the company says, including Trinidad, Jamaica, Guyana, Barbados, Panama, Guatemala and Java.

The final blends are aged in previously used bourbon barrels.
