I went to see Beer Wars last week and in the shot at Sam's home it showed a carboy with (I'm assuming) beer. The question was about it being in the light, I have always been told that UV exposure was REALLY bad but can it just make different fl

You are right!! I asked Sam and he said that while he usually keeps the fermenting carboys on a counter in a darker area of the house, things got moved all around that day to accomodate the cameras and lighting equipment. The carboy ended up on the counter during the shoot, but (don't worry!) it moved back into the dark area. By the way, Sam reports that the beer was one that he brewed with friend and local homebrew store owner Doug Griffith and that it turned out great!
