Licorice bitters are a herbal cocktail bitters flavored mainly with licorice root, used in dashes.
Licorice at dash strength. The note itself is easy to add elsewhere; the concentration is the part nothing else repeats.
Angostura plus a drop of anise liqueur
The bitters hold the bitterness and the anise gives the licorice direction; the liqueur brings its own sugar, so the drink’s syrup comes down.
It gives the same licorice-anise side at dash concentration and with no sugar; it is stronger and wormwood-bitter, so a single drop usually does.
Anethole and glycyrrhizin are both robust, so a licorice bitters is among the longest-lived bottles on the shelf. Cold may cloud it — anise coming out of solution, reversible on warming — and sunlight will do more damage than time.
