The Harvey Wallbanger is a 1971 cocktail that combines Vodka, Sweet Herbal Liqueur, and Orange Juice. The drink is said to taste like a cross between an Orange Julius and a Screwdriver. The vodka gives it a smoothness, while the herbal liqueur adds a bit of sweetness and depth of flavor. The orange juice rounds out the drink and gives it a refreshing tang. The history of the Harvey Wallbanger is a bit murky. Some say that the drink was invented by mixologist Donato ""Duke"" Antone in Hollywood, California. Others claim that it was created by bartenders in England in the early 1970s. Regardless of its origin, the Harvey Wallbanger has become a popular cocktail around the world.
