A liqueur is an alcoholic drink composed of distilled spirits and additional flavorings such as sugar, fruits, herbs, and spices. 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. Today they are produced the world over, commonly served straight, over ice or most likely used in your favorite cocktails.
