For many many years I haven't waited the christmas that anxiously, that I would have an advent calendar. Not even a chocolate one. This year I chose to make an exception to that. I got a recommendation to get a proper one from Lieferello.de. Here it is:
This calendar contains 24 (as any advent calendar does) cans of beer. Nice! 
Finally a good reason to count days for the 1st of December.
If you want to order one, here is the direct link to Die Weihnachtsbrauerei Bier.
