Ouzo "This is "uso Massalia", my friends"—referring to its high quality. The term subsequently spread by word of mouth, until "tsipouro" gradually became known as ouzo. However, the major Greek dictionaries derive it from the Turkish word "üzüm" 'grape'. Ouzo production begins with distillation in copper stills of 96% alcohol by volume (ABV) rectified spirit. Anise is added, sometimes with other flavorings such as star anise, fennel, mastic, cardamom, coriander, cloves, and cinnamon. The flavoring ingredients are often closely guarded company "recipes", and distinguish one ouzo from another. The result is a flavored alcoholic solution known as "flavored ethyl alcohol", or
Ouzo more commonly as "ouzo yeast"—"μαγιά ούζου" in Greek—the term for "yeast" being used by Greeks metaphorically to denote that it serves as the starting point for ouzo production. The "ouzo yeast" is then distilled. After several hours of distillation, a flavored distillate of approximately 80 ABV (% Alcohol By Volume) is produced. The spirit at the beginning of the distillation (heads) and end (tails) is usually removed to avoid light and heavy alcohols and aromatics. The heads and tails are usually mixed and distilled again. The product of this second distillation can be used to produce a different quality ouzo.
