Gin is made from a mash of cereal grain - primarily corn, rye, barley and wheat - that is flavoured with botanicals to give it a distinct taste. Though many botanicals are used by individual producers, juniper is usually the most prominent fragrance and flavour note, the common factor that unifies all gins. Others include coriander, lemon and orange peels, fennel, cassia, anise, almond and angelica.
