Faxx, a Danish Beer, served in 1 Litre (Yes you did just read that correctly) tins.
Very very nice stuff, even when warm.
Wiesbier (or however its spelled) is superb also.
Though my all time favourate was a brew my Grandmother made up about 5 years ago as a one off, utterly evil stuff (It got you from the legs up, you head being the last to be hit) and a great taste :-)
I must admit however I do prefer wine, always have, always will.
