Ron Montero Gran Reserva from Spain has a very nondescript bottle design, bland label and very weak amber color. Strong alcohol to the nose and palate. Artificial spices to wrap it up. Not a pleasurable experience by any measure.
And the taste doesn´t make it better.. The closest thing i have tasted to this is Club Havanna white rum. So if you have a bottle of this and want to finish it. I would say that you shall bring on the ice and the ginger beer.
