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) description of the flavour symmetry is described by a chiral group . If all quarks had non-zero but equal masses, then this chiral symmetry is broken to the "vector symmetry" of the "diagonal flavour group" , which applies the same transformation to both helicities of the quarks. This reduction of symmetry is a form of "explicit symmetry breaking". The amount of explicit symmetry breaking is controlled by the current quark masses in QCD. Even if quarks are massless, chiral flavour symmetry can be spontaneously broken if the vacuum of the theory contains a chiral condensate (as it does in low-energy
