375ml sizeNext time you’re pouring rum cocktails for your cohorts, serve up this nugget of rum trivia: Bacardi 151 gets its name for its proof level of 151. At 75.5% alcohol by volume, that’s nearly double the level of typical rum. Wowza. All that alcohol means it’s highly flammable, so be responsible friends. Balance Bacardi 151’s punch by using it sparingly in sweet, fruity drinks, such as Hurricanes or Rum Punches.
