A Vesper drink, also known as a Vesper Martini, is a cocktail that was invented by author Ian Fleming for his iconic British secret agent, James Bond. The drink first appeared in Flemings Casino Royale, which was published in 1953, and was named after the fictional double agent and Bond love-interest, Vesper Lynd. The original recipe called for gin, vodka, and Kina Lillet, but since that form of Lillet is no longer produced, modern bartenders need to modify the recipe to mimic the original taste). The recipe for a Vesper drink typically includes:

• 3 ounces gin
• 1 ounce vodka
• 1/2 ounce Lillet Blanc aperitif

To prepare the drink, all ingredients are poured into a cocktail shaker filled with ice cubes, shaken well, and then strained into a chilled cocktail glass). The Vesper is commonly served before dinner). While the original recipe called for Kina Lillet, which is no longer available, Lillet Blanc or dry vermouth can be used as a substitute. The Vesper is a potent mix of gin and vodka with Lillet, and it has a slightly sweet, bitter taste contributed by Lillet, while the vodka tames the gins botanicals. Although the Vesper drink is not as well-known as other cocktails, such as the vodka martini and the mojito, it can be ordered at most bars, and many bartenders are familiar with it.
