Plymouth Gin gin, purportedly due to a higher than usual proportion of root ingredients, which bring a more 'earthy' feel to the gin as well as a softened juniper flavour. There is also a 'navy strength' variety which is 57% ABV (100° English proof), being the traditional strength demanded by the British Royal Navy. <ref name="http://www.plymouthgin.com"></ref> A 47% ABV (94 U.S. proof) version is distributed worldwide. Plymouth also produces a sloe gin, but has discontinued its Fruit cups and Damson liqueur. Gin, originally being a relatively cheap alcoholic beverage, was bought by the poor and caused considerable social problems, illustrated by the
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
