From the Producer's Website: What makes Blanco Supremo so special? It is the only rum that we filter three times. Of course, it goes through our time-honored distillation process, and it is cask aged in white American oak casks for 2-5 years, the same as Brugal Añejo. But it is the triple filtering that sets it apart by enhancing its smoothness and removing its color – if you like your rums clear, then Blanco Supremo is for you. It has the all the smoothness of great vodka, but all the character of great rum.
