Hiddenseer Radler is the alcohol-free Radler in the Hiddenseer range from Rügener Insel-Brauerei, a brewery based on Rügen, a Baltic island off the northern coast of Germany. The Radler sits alongside the brand's wheat beer as one of the brewery's non-alcoholic options, giving the range a small but focused selection of alcohol-free styles from the same island producer.
