NPR’s Renee Montagne recently interviewed author Richard Barnett about his recently published The Book of Gin. The book traces the history of gin back to the work of 8th century Arabic alchemists who were doing extensive work with distillates and who originally prepared it as a medicine. Proceeding through the centuries, the tale arrives in early 20th where Barnett sees fit to mention a curious cocktail called the Kuhlai Khan No. 2 by some chap named Crowley.
