Diplomatico Reserva Exclusiva is a blend of 20 per cent light column distilled rums with 80 per cent pot still rums aged up to 12 years, a proportion of which are rums from exceptional barrels which are used in Master Blender Tito Cordero's secret preparation. Although he won't reveal the ages of the rums used, Tito has disclosed that he mixes these exceptional rums with a little cane sugar prior to blending with the main body of rums to amplify their flavour so they impart a slight touch of sweetness & a distinctive flavour to the finished rum.
