Liqueurs are sweetened alcoholic beverages flavoured with fruits, herbs, spices, or other ingredients. Their taste can range from sweet and fruity to herbal and spicy, often with a syrupy texture.

Liqueurs have historical origins in herbal medicines, with recipes found in ancient Egypt and Greece. Monks in the 13th century further popularised them, and the recipes for some, like Chartreuse, remain closely guarded secrets.
