As near as I can tell, people either love wheat beer, or they don't. Few people fall in between.
Maybe some people are put off by the spices? I mean, I love cardamom and coriander, so I'm all for beer that contains either. But if you're not a fan of those flavors, wheat beer probably isn't gonna thrill you.
What I find odd about wheat beer is that it took so long to catch on in the United States. It's been brewed in Europe for centuries -- well over a thousand years. But I never found any evidence of it being brewed here in the nineteenth century, or even after Prohibition, until, as I noted earlier, just a few years ago.
