Guignolet is a French wild cherry liqueur which is widely available in France, but is not widely available internationally. The leading producer is the company Giffard in Angers, France, the same town where Cointreau is produced. The Cointreau brothers have been instrumental in its reinvention, the original recipe having been lost.
Guignolet takes its name from guigne, one of a few species of cherry used in its production. (Black cherries and sour cherries are also used.) It has an alcohol content between 16 and 18º proof (12%) and has an aroma vaguely reminiscent of whiskey and a very sweet taste.
