Yes, I am talking about regular licorice root. Unless the powdered licorice root has a sweetener added (and some commercial versions do), licorice does not taste very sweet on its own. If you chew licorice root, initially it is very bitter. After a while, the characteristic licorice flavor appears, and a sweetness can be perceived, and then a numbing. The source of the sweetness is the compound glycyrrhizin, which is nominally fifty times sweeter than sugar, but the perception of the sweetness is more of an aftertaste that is not immediately there, but lingers long after exposure. Unfortunately, glycyrrhizic acid is also toxic, and is the reason why licorice consumption is limited, as well as the quantity that can be put into spirits. You can get high concentrations of oils from anise and fennel to make a fairly sweet spirit, but you should not impart high concentrations of licorice or you may exceed limits for glycyrrhizic acid. Peoples perception of the sweetness of licorice root vary, mostly likely a genetic predisposition.
We do use licorice root in our gin to provide a bittersweet aftertaste. It is more likely to be perceived after finishing a sip, rather than while drinking, we find.
