Anise-flavored aperitifs are alcoholic beverages that are typically served before a meal to stimulate the appetite. Two popular examples of anise-flavored aperitifs are OUZO and Pernod. OUZO is a Greek anise-flavored aperitif that is usually served with water and ice, while Pernod is a French anise-flavored aperitif that is often served with a splash of water. Both drinks have a strong licorice flavor and are usually served chilled.
