Green liqueur is an alcoholic beverage made from herbs, spices, and other natural ingredients. The most popular green liqueurs are ABSINTHE (8 letters), Pernod (6 letters), and Crème de Menthe (13 letters). ABSINTHE is a strong, anise-flavored spirit that originated in Switzerland in the late 18th century. Pernod is a French anise-flavored liqueur that was first produced in 1805. Crème de Menthe is a mint-flavored liqueur that was first created in the 19th century. All three of these liqueurs are popular for their unique flavor and are often used in cocktails.
