Ouzo is an anise-flavored drink that is widely consumed in Greece. It can be drunk neat or mixed with water. It is very similar in taste to Sambuca (Italy), Pastis (France), Arak (Lebanon), or Salmiakki (Finland).
A good and balanced ouzo may contents until 46% alcohol which protects it against the affection of the time and helps keeping its aroma and flavor. When water or ice is added to ouzo, its color, which is clear, turns milky white. This is the effect of binding anethole, the essential oil of anise, which is soluble in alcohol but not in water.
Ouzo drinking is an art. Or maybe it's a way of life.
