Not the vodka martini.
A painstaking study of Fleming’s complete oeuvre has shown that James Bond consumed a drink, on average, every seven pages.
Of the 317 drinks consumed in total, his preferred tipple was whisky by a long margin—he drinks 101 in all, among them 58 bourbons and 38 scotches. He’s pretty fond of champagne (thirty glasses), and in one book, You Only Live Twice (1964), which is mostly set in Japan, Bond tries sake. He likes it: he has 35 of them.
Bond only opts for his supposed favorite, vodka martini, 19 times, and he drinks almost as many gin martinis (16).
The famous “shaken, not stirred” line appears for the first time in Diamonds Are Forever (1956) but isn’t used by Bond himself until Dr. No (1959). Sean Connery was the first screen Bond to utter “shaken, not stirred,” in Goldfinger (1964), and it occurs in most of the films thereafter.
