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
Flavour (particle physics) other words, the theory possesses symmetry transformations such as formula_1, where and are the two fields (representing the various "generations" of leptons and quarks, see below), and is any unitary matrix with a unit determinant. Such matrices form a Lie group called SU(2) (see special unitary group). This is an example of flavour symmetry. In quantum chromodynamics, flavour is a conserved global symmetry. In the electroweak theory, on the other hand, this symmetry is broken, and flavour changing processes exist, such as quark decay or neutrino oscillations. All leptons carry a lepton number . In addition, leptons carry weak isospin,
