Shandy and radler are peas in a proverbial pod, each bringing a light, fruity effervescence mixed with the bready yum-yum of beer. The difference stems from the fact that a radler is more likely to have additional fruit juices in it such as grapefruit. The primary recipe for both the shandy and the radler is an even mixture of beer (most likely a blond lager) and a citrus fruit drink like lemon-lime soda or lemonade. From there, few people stick to the script and most choose to add other fruity additions to the drink.
