Man I can't imagine enjoying most of the beers that they brew on that show...especially the anti-Reinheitsgebot beer that used cucumber juice instead of water that they brewed with Greg Koch. I find the show entertaining but only because I love beer so much.I've actually tried one of them (the NOLA zombie beer). It was drinkable in small amounts, but not something I'd want a pint of. The show is pretty much pure entertainment, and it's a fun experience. There's a lot that goes on that gets cut, though. I know the beer that I tried was not the one they brewed onscreen. They had major issues with the water filtration system, so they wound up just brewing the batch they served on the brewery pilot system.
I kind of assumed that the beers that they serve are not actually the beers that they show them brewing. Their carelessness especially when it comes to chilling the wort seems like it could cause major issues in the beers. On more than one occasion I have seen them pitch yeast into wort that is still steaming.
They don't seem to measure ingredients either and just do it by 'feel' especially with hops, spices, etc. I don't really care but it kind of sends the message that you can just throw a bunch of crap together and make a great beer.
If they focused a bit more on recipe formulation and the technical things I would like it a lot more but then it would turn off the average viewer who just wants to see them crack jokes.
