A liqueur is an alcoholic drink composed of spirits and additional flavorings such as sugar, fruits, herbs, and spices. Often served with or after dessert, they are typically heavily sweetened and un-aged beyond a resting period during production, when necessary, for their flavors to mingle.

Liqueurs are historical descendants of herbal medicines. They were made in Italy as early as the 13th century, often prepared by monks (for example, Chartreuse). Today they are produced all over the world, commonly served neat, over ice, with coffee, in cocktails, and used in cooking.
