I just came back from a festival that was serving mulled cider and mulled wine. I've heard of a few mulled beers, such as buttered beer, so I know people must make them. Has anyone out there tried making one or tasted someone else's?
What type of beer would be good for mulling? What characteristics would shine through or stand out at high temperatures? Also, is it even worth carbonating in the bottle if you're planning to mull it?
