Mulled Beer for the Holidays

Via Lifehacker, some instructions on mulling beer during this holiday season:

You may have tasted mulled wine before, especially around winter holidays, but if you're an American reader you've most likely never drank anything but ice cold beer. For the better part of history people drank beer at ambient temperatures, and from the 15th to 18th centuries it was wildly popular to drink beer hot and steeped with spices and sugar.

This may seem like sacrilege, but don't knock it until you've tried it. While traveling in Bavaria, I visited a Weihnachtsmarkt where hot, mulled cherry lambic was being served. I was skeptical, but it turned out to be delicious:

UPDATE: I stand corrected. My Bavarian friend reminds me that the particular Christmas market in question was in Dresden - Bavarians would not put up with such foolishness.
