Rum El Dorado 15 Year Old. A delicious blend of Caribbean rum, El Dorado 15 Year Old marries spirits from the Enmore and Diamond Coffey stills, the Port Mourant double wooden pot still and the Versailles single wooden pot still. All the tasty spirits are blended and then aged in bourbon oak casks before bottling. This was rated the best rum in the world at the International Wine and Spirit Competition four years running, and for good reason.
