I think this is a good point. I'm one of the few who really does think I can "taste" metal in any beer poured from a can. I do believe the chemical analyses from Sierra Nevada (i.e., that there's no difference in the product), and I've concluded that... 1) Yes, it is something that is just in my head. 2) And/or possibly the can has a smell associated with it that for me, negatively affects the beer's flavor. So for me personally, I don't often buy cans because I know that I'll probably not enjoy the beer as much as from a bottle (for these two reasons). Plus the ritual of bottle pouring is more enjoyable for me.
