Ouzo Ouzo Ouzo (, ) is a dry anise-flavoured aperitif that is widely consumed in Greece, Cyprus, Lebanon and Israel. Its taste is similar to other anise liquors like "rakı", pastis and sambuca. Ouzo has its roots in "tsipouro", which is said to have been the work of a group of 14th-century monks on Mount Athos. One version of it was flavoured with anise. This version eventually came to be called ouzo. Modern ouzo distillation largely took off in the beginning of the 19th century following Greek independence. The first ouzo distillery was founded in Tyrnavos in 1856 by Nikolaos Katsaros,
Flavour (particle physics) chiral symmetry breaking with the formation of a chiral condensate. Other phases of QCD may break the chiral flavour symmetries in other ways. Some of the historical events that led to the development of flavour symmetry are discussed in the article on isospin. Flavour (particle physics) In particle physics, flavour or flavor refers to the "species" of an elementary particle. The Standard Model counts six flavours of quarks and six flavours of leptons. They are conventionally parameterized with "flavour quantum numbers" that are assigned to all subatomic particles. They can also be described by some of the family symmetries proposed
