Radlers are half beer, half lemonade. There is a surprising amount of difference between them too. I suspect we’ve tasted maybe 6 different kinds (most in bars), and one at a bar in Mitte had a nice fresh orange flavor. I can’t normally stand fruit in beer, but clean tasting German beer really works well with the juice.
That said, I’ve tended to avoid them. Alissa likes them though, and they are usually half the alcohol as a normal beer. Perfect for breakfast!
Oh, anyway, this one wasn’t particularly good. Too much sour, not enough “lemon citrusyness”.
