So maybe the whole cooking video thing is hit the social-media saturation point, but when this one popped up on my Facebook news feed a couple weeks back, it looked worth a try.
Beer can chicken has been around for some time, and in general, it's not really worth it to waste good beer on the dish. All the beer really does is provide a source of moisture to keep the chicken from drying out. There really won't be much flavor that comes through.
Which is not to say that beer can chicken isn't great, it is, but as a general rule you don't need to use good beer on it.
