The Vesper is not for the faint of heart, containing a whopping 4 ounces of liquor, plus a splash of Lillet Blanc (or Cocchi Americano, if you prefer). This now-classic cocktail is unique because it was invented not by a bartender, but by author Ian Fleming in his James Bond novel Casino Royale. The Vesper is a martini riff made with both gin and vodka, as well as an aromatized wine.
