One of the BEST beers you can drink, you'll have to travle to get. You can only buy in in a monistary where monk's make it. (No Shit)
If you happen to be in Germany, Take a train to what they call in the U.S. wildfleckin. Although I think it's pronounced Veal-fleckin. Anyway, From there you have to take another train to Geissen. It use to be one of the few trains that pulled by a electric/diesel engine. When you get off the train, Take a cab or ask directions to the monistary, It's about a 20 - 30 minute walk (Uphill!) But for then 9 marks for a half-liter 12 Marks for a full liter. + you can keep the mug. It's a light amber that goes down like water! Scary smooth. It's called the Croitzberg Monistary. There are a lot of monks all over germany and europe making klosterbrau. There's nothing quite like it. If you can go expeirience them for yourself.
Sorry about the mis-spelled words but.....
