Tanqueray is a brand of gin produced by Diageo plc and marketed worldwide. Although originated in London, it is now produced in Scotland. Tanqueray is a London dry gin, reflecting its distillation process and origin in Bloomsbury, London. London dry gin is made by double distilling grain, with select botanicals added during the second distillation. While the Tanqueray recipe is a closely guarded trade secret, it is known to contain four botanicals: juniper, coriander, angelica root, and liquorice, all common botanicals in gin productions overall.
