The only beer I've ever found to be undrinkable was MGD 64 and Rogue Voodoo Donut Maple Bacon Beer. Other than that it's all good (Even Keystone Light).
I hear you man..... I basically only drink 3 things - water, coffee and beer. I love the taste of beer and find myself wanting to just go pour a beer because of the flavor. The other two....... well, obviously for the caffeine and the fact that they have no calories - which allows me to keep drinking the beer.
