Some historians have speculated that Bond slipped up in specifying Kina Lillet-a quinine-flavored white wine aperitif whose distillery also produced vermouth-intending for vermouth all along. The formula for Lillet has since changed, circa mid-1980s, making way for a new lighter, sweeter version with a lower dosage of quinine. He specifies a strong formula of vodka, gin and Kina Lillet, “shaken, not stirred,” of course. A true Bond-style cocktail, the Vesper was first mentioned by writer Ian Fleming in his 1953 novel, Casino Royale, as a drink order detailed by Bond himself.
