In the Afterburner, Sambuca adds a sweet, anise-flavored base, while Absinthe brings a herbal complexity with a slightly higher alcohol content, and the Aniseed liqueur reinforces the anise flavor, making it the dominant taste profile of the cocktail. The combination creates a shot that is both potent and flavored with a deep licorice-like taste, appealing to those who enjoy anise-flavored spirits.
