El Dorado 15 ans is a traditional rum from the Guyanese distillery Demerara Distillers, which draws its aromatic power from its distillation method. It is a blend of several rums distilled in coffey stills and the Port Mourant wooden still.
The casks used for ageing are those that have previously contained bourbon.
This 1 liter version at 40° (instead of 43° for the 70cl version) is quite rare to find on the European market.
