Rum Heffron was created in 2020 on the occasion of the centenary of the return of Czechoslovak legionaries to their homeland, Czechoslovakia. The legionaries fought in Russia in 1914-1918 against the Russian Bolsheviks. Heffron is the name of one of the ships on which the legionnaires sailed from Vladivostok via Panama back to Europe. Therefore, the rum is of Panamanian origin and its design is inspired by letters sent by legionaries from their travels around the world home. Rum Heffron became one of the flagships of the manufacturer the Green Tree Distillery.
