One shot of 84-proof sambuca contains 100 calories. Almost all the calories come from the alcohol itself, as the drink has only a negligible amount of carbohydrates, proteins and no fat.
Sambuca is an Italian alcohol that is flavored with anise. This flavor is commonly called licorice. Sambuca is usually clear, but deep blue and red colors are also available. Regardless of color, one shot or 1 fluid ounce contains approximately 100 calories. When combined with water, the drink forms a milky solution. Sambuca shares this property and several others with a range of anise-flavored alcohols, including arak and absinthe.
