Rothaus Natur Radler Zitronenzäpfle 0,0% is part of the Zäpfle series, the brand's range of alcohol-free styles. The non-alcoholic radler is assembled from a naturally cloudy dealcoholised beer and a lemon lemonade, with the distinction that no crystalline citric acid is used: the tartness comes solely from natural acid present in fruit juice. With 9 IBU, the beer component contributes a light bitterness that gives the blend more structure than a plain fruit drink.
