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) a decay involving a bottom quark or antiquark . Since first-order processes are more common than second-order processes (involving two quark decays), this can be used as an approximate "selection rule" for weak decays. A special mixture of quark flavours is an eigenstate of the weak interaction part of the Hamiltonian, so will interact in a particularly simple way with the W bosons. (Charged weak interactions violate flavor). On the other hand, a fermion of a fixed mass (an eigenstate of the kinetic and strong interaction parts of the Hamiltonian) is an eigenstate of flavour. The transformation from the former
