"The Bacardi Island" is Freeport, Bahamas.
The Bacardi family, Cubans, fled Cuba with their Spanish passports to the U.S. when Fidel took power. Some of the boys returned to dynamite the factories they left behind. Their new headquarters in Puerto Rico allow them to skip U.S. Liqour Tax on every bottle. All they have there, unless it's changed in the last few years, is a pilot bottling plant which gives tours to the cruise ship passengers.
Freeport has their distilleries, and the molasses comes in by tankers from Guiana.
You want real rum, try Dominican . . . or Nicaraguan . . .
