The French 75 marries gin and lemon with a sugar's worth of sweetness, then lengthens it with Champagne — a citrus sour given lift and sparkle. Its kick is said to feel like being shelled by the French 75mm field gun, the namesake Harry MacElhone invoked when he documented an early version in 1920s Paris. The gin-and-Champagne form crystallized through Judge Jr.'s Here's How (1927) and was carried to fame by the 1930 Savoy Cocktail Book.
