My Bro swears by these things

I'm trying to get my Bro to make up a couple of stainless steel punch-down tools for this year's wine making, but his spare time efforts are going to these beer can chicken steamers - go to cabin, light fire, pop three Buds and place in rings, insert chicken over cans (squwawk!), put on fire, 60 to 90 minutes later beer-steamed-chicken-heaven. I keep meaning to ask if it matters how heavily you and the other folks in the cabin drink during the cooking time. Two and three can models now available.
