If you ever get the Chance, try a Bayreuther Aktien Landbier, i dont know if they export it (in Germany its avaiable in many well sorted Beer Shops) but if they do, you could have beer thats dark (not as dark as a Guiness), tasty and with a flavour of sweet malt, not so strong like the dark belgian Trapist Beers but stronger than other german dark beers like Altbier for example.
