Beefeater Gin Seville oranges, whole juniper berries and other natural botanicals for a full 24 hours prior to distillation. This long process allows for a full extraction of flavour from the botanicals, capturing a wide range of volatile oils. The distillation itself takes around eight hours to complete, overseen by master distiller Desmond Payne – with the spirit then taken to Scotland where it is blended and bottled at 40% ABV. 47% ABV is common in the USA. A super premium version of Beefeater was launched in Syon House on 30 October 2009. Beefeater '24' with its additional botanicals of Chinese Green
Flavour (particle physics) basis to the flavor-eigenstate/mass-eigenstate basis for quarks underlies the Cabibbo–Kobayashi–Maskawa matrix (CKM matrix). This matrix is analogous to the PMNS matrix for neutrinos, and quantifies flavour changes under charged weak interactions of quarks. The CKM matrix allows for CP violation if there are at least three generations. Flavour quantum numbers are additive. Hence antiparticles have flavour equal in magnitude to the particle but opposite in sign. Hadrons inherit their flavour quantum number from their valence quarks: this is the basis of the classification in the quark model. The relations between the hypercharge, electric charge and other flavour quantum numbers hold
