There's 2 camps on this. One anti-beer can chicken and one pro. If you say you are against it the pro side looks at you like you punched a baby. I say do what you enjoy. There are components of flavor that are impossible to measure. I can give one word of warning. A buddy of mine got the bright idea to do a beer-can turkey with Foster's can. When they were taking the turkey off he spilled the scalding hot beer all down his legs and got 2nd degree burns. On the plus side, they said it was the best turkey they ever had. I think all the other booze they drank leading up to this might have led to that particular conclusion.
