The Vesper Martini is a unique cocktail because it was invented not by a bartender, but by an author. Ian Fleming created the drink in his first James Bond novel, *Casino Royale*, published in 1953. In the book, Bond gives specific instructions: 'Three measures of Gordon's, one of vodka, half a measure of Kina Lillet. Shake it very well until it's ice-cold, then add a large thin slice of lemon peel.' Bond names the drink after Vesper Lynd, the novel's female lead. Unlike a standard Martini which uses gin or vodka with vermouth, the Vesper uses both spirits and replaces vermouth with Kina Lillet (now sold as Lillet Blanc). This drink popularized the 'shaken, not stirred' trope, which scientifically results in a colder, more aerated, and slightly more diluted drink compared to stirring.
