A lot are not nasty tasting you know.
Despite the health concerns, a lot of beers here are flavoured with fruity tastes, like the "Kriek" beer, which is a made with cherries. There are also banana taste, and with honey, rhum, spices, cinnamon, cider, ...
But I do not drink beer (and alcohol btw) since a long time because of my health issues, so I won't recommend anyone to try them, especially for ppl in the same situation as me.
