Have been produced by blending alcohols flavoured by means of distillation or maceration using aniseed and possibily fennel seed, mastic from a lentiscus indigenous to the island of Chios (Pistacia lentiscus Chia or latifolia) and other aromatic seeds, plants and fruits; the alcohol flavoured by distillation must represent at least 20 % of the alcoholic strength of the ouzo.
