Grand Marnier is a French liqueur that blends cognac with essence of bitter orange, creating a rich, complex flavor profile with notes of vanilla, toffee, and citrus. With 40% ABV (80 proof), it's stronger than many orange liqueurs and can be enjoyed neat, on the rocks, in cocktails like the Sidecar or Margarita, or used in desserts like Crêpes Suzette. Its cognac base gives it a deeper, warmer character than neutral-spirit-based triple secs.
