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) , which is − for the three charged leptons (i.e. electron, muon and tau) and + for the three associated neutrinos. Each doublet of a charged lepton and a neutrino consisting of opposite are said to constitute one generation of leptons. In addition, one defines a quantum number called weak hypercharge, , which is −1 for all left-handed leptons. Weak isospin and weak hypercharge are gauged in the Standard Model. Leptons may be assigned the six flavour quantum numbers: electron number, muon number, tau number, and corresponding numbers for the neutrinos. These are conserved in strong and electromagnetic interactions, but
