70cl bottle of Havana Seleccion de Maestos golden rum 45% ABV. Selección de Maestros has benefited from an eye-catching packaging upgrade and is bottled at 45% for extra oomph. The Gold Medal-winning liquid inside Havana Club Selección de Maestros remains the same as for the old Cuban Barrel Proof - as the name suggests, the casks have been hand-picked by the maestros roneros from the company's finest aged stocks.
