Recipe Tips and Tricks

  • Choose Your Spirit: Rum is traditional; vodka yields a lighter, cleaner profile.

  • Use Real Vanilla: Pure vanilla extract delivers the best flavor—vanilla bean can be used for extra depth.
  • Cool Completely: Ensure both the simple syrup and coffee are at room temperature before adding alcohol to preserve flavor and alcohol content.
