Ron Centenario 20-Year rum is produced from Costa Rican sugar cane which is turned into molasses before aging in American white oak barrels up to 20 years using the solera aging system.
The company producing Ron Centenario 20-Year rum used to be named Seagram de Costa Rica, but in 2002 changed its name to Centenario Internacional. The rum wasn't sold outside of Costa Rica until 2007.
