Did you know the letters in “advent calendar” can be rearranged to spell “a candled tavern”? That vaguely sounds like a Christmas-y place to drink. Take one more leap on your logical sleigh and it makes perfect sense that an advent calendar should reveal a different can of beer for every day in December leading up to (and including) Christmas. Get complete instructions to customize your own beer advent calendar on Instructables. Soon you’ll be brewed off and red nosed when it rains beer.
