Ouzo
History
The history of ouzo is somewhat murky, but some claim it may date back in one form or another to ancient times. Its precursor is raki, a drink distilled throughout the Byzantine [1] and later Ottoman Empires, often in those days of quality approaching moonshine (similar liquors in Turkey and many Arab countries still go by that name).
Name
Perhaps the most probable origin of the name "ouzo" is discussed in a 1959 article in The Times of Thessaly.
How ouzo is made
Ouzo starts as a strong spirit made from pressed grapes or raisins. Other herbs and berries may also be added at the fermentation stage. The distinctive smell of ouzo comes from the addition of anise (or star anise) as a flavouring, but other ingredients, varying according to the producer, are also used; common ingredients include coriander, cloves, angelica root, liquorice, mint, mastic, star anise, wintergreen, fennel, hazelnut, cinnamon and lime blossom. The alcohol and flavourings are placed in warmed copper stills and distilled; higher-quality ouzos may be distilled several times. The resulting spirit is stored for a few months, and then diluted, usually to around 40% ABV.
Aperitif drink
In modern Greece, ouzeries (the suffix -erie is imported from French) can be found in nearly all cities, towns, and villages. These cafe-like establishments serve ouzo with mezedes -- appetizers such as octopus, salad, sardines, calamari, fried zucchini, and clams, among others. It is traditionally slowly sipped (usually mixed with water or ice) together with mezedes shared with others over a period of several hours in the early evening.
Appearance
When water or ice is added to ouzo, which is clear in color, it turns milky white; this is because the etheric oils are soluble in alcohol but not water. Diluting the spirit to less than around 40% ABV causes it to separate into an aqueous and an organic phase, whose fine droplets scatter the light.
