Here's my thoughts on why the beer can whole chicken is better than most. First I don't think it's the beer in the can either as others have said drink the beer put water back in it's place works just as good. If you plug the neck hole with a potato it seems to add moisture by sealing the insides of the chicken moisture is supposedly retained. Next the most important part is the upright chicken the breast which are done at 165 degrees are further from the heat and the thigh done at 180 is closer to the heat source if your using bottom heat such as a pellet grill or charcoal this is why it works. It also evens out the outside skin cook without flippin or turnin. Just my opinion everybody is entitled to one. Must admit never tried the spatchcock squish ha! laid em down and plenty rotisseries never as good as the upright position.
