The term goes back to the 1970s.
The Castellon book is indeed an important one. Art Cocktail I don’t know and will investigate. Schumann’s Tropical Drinks is also an important one form that era.
The Sardi’s book I added to the list covers a lot of disco drinks and shooters, sometimes amusingly. I don’t know how far we want to go with that stuff though: does a book like John J. Poister’s 1989 New American Bartender’s Guide qualify as canonical? It pretty much summed up the age (and brought us the Jungle Bird).
Benson & Hedges Presents Drink Recipes from 100 of the Greatest bars (1979), with recipes curated by Playboy (presumably Thomas Mario), is another that defines that age, in all its gaudy horror.
I added a couple of other non-English books to the list the other day, but it definitely needs more. There should be a IBA guide there, for one. It would be good to have something from behind the Iron Curtain (all I have in my collection is B. Rutkauskiene’s 1973 Kokteiliai, in Lithuanian, and I don’t know if it was based on a Russian model).
