You can spot him a mile away. He's usually the one with the hat worn slightly askew and the top three buttons of his shirt undone, saying the word "bro" over and over. He's at a table at the bar, maybe with a girl on his lap. And he's drinking his favorite brew: Blue Moon.
This man is the beer poseur. And since the popularity of craft beer isn't going away anytime soon, neither is he. He's going to keep on drinking Blue Moon and telling a girl wearing too much makeup it's the end-all, be-all of craft beer until somebody knocks some sense into him.
That's not to knock Blue Moon. It's always tasted a little too much like an Orange Julius to me, but its brewer, Keith Villa, has a doctorate in brewing from Belgium. Dude knows what he's doing. Just because it's made by Coors doesn't make it bad.
Remember the lessons of high school. Don't be a beer snob when confronting the beer poseur; he might be a little misguided, but his heart (at least in beer) is in the right place. Educate him. Expand his horizons. And if he still prefers Blue Moon, I'm sure Pete Coors can use the money.
To school him right, here are a couple other Belgian-style wit beers he might want to try; I've attempted to pick ones that are readily available, but you can call me a poseur if you want.
St. Bernardus Wit (Belgium): Probably the best there is, was and ever will be. It's amazing how fresh it tastes right out of the bottle. A bit pricey, and you might need to go to the Foodery or Food & Friends to get it, but it's worth it.
Allagash White (Maine): More readily available than the St. Bernardus, and approaching it in quality, you can even find this beer from Portland on tap sometimes. It's smoother than Blue Moon and is simply a great American beer.
Celis White (Michigan): From the lineage of Hoegaarden brewer Pierre Celis, the name passed to Miller and now to Michigan Brewing Company. It still produces a beer with a solid taste though it's a bit heavier than other white beers.
Walt Wit (Philadelphia): The relatively new offering from the also relatively new Philadelphia Brewing Company isn't quite as good as their other beers, but it can't be beat for value among white beers.
