we only tested using cans of beer. Since then we have seen additional claims regarding different devices and different beers, so we went back to amend our testing. In our first go round, we found that beer in a can will not boil. But what about using one of those metal racks/pans for holding the can? What about those porcelain chicken and turkey sitter devices? What about Weber's pan/cup combo device? Also, we didn't document the beer we used in the first test, so this time, we will repeat the beer/no beer test using the "best" device and using a known beer.
