Kaiserdom Lemon 0,0% is an alcohol-free German radler (a beer and lemon blend) made by combining 50% Kellerbier, an unfiltered lager, with 50% lemon. The brewery, Kaiserdom, is one of the oldest in Germany, founded in 1718. Natural lemon flavour is added to the wheat beer base, and the finished drink is isotonic. Citrus zest, banana and clove from the yeast come through, with a refreshing finish.
