Calanda Radler 0.0% Grapefruit is an alcohol-free radler brewed by Calanda in Switzerland. A radler, sometimes called a shandy, is beer mixed with lemonade. This one is built from roughly 60% lemonade and 40% alcohol-free beer, with a small amount of grapefruit juice from concentrate added on top. That makeup gives it a grapefruit flavour, with the lemonade keeping it citrus-led rather than beer-forward. It comes from the Calanda Bräu brewery, and it is an award-winning drink.
