I waited to the end of the fermentation cycle. I was surprised that it was so 'funky'.
I was talking to a brew master before I bought the kit, and he said that a thick, and solid, layer of 'stuff' on the top of a fermentation tank isn't exactly bad, but what I described wasn't 'ideal' he said. (Um, okay) He said that I should have taken a sample from the middle of the tank, and looked at it, and smelt it, to see if it was 'usable'. I lauhged, and he said that some of his 'mistakes' in brewing have made the best brews. He said that is possible that I had a great brew at the time, and freaked out at the 'look'. But his partner said that I likely did the world a favor. He said that most of the brews they have had the growths on have been the result of inadequately sterilized equipment, and would have tasted like a steeped sweat sock, and likely made me rather sick. The first guy agreed, but still wished I had spent more time looking at it to see if it was totally spoiled, and not 'usable'?.
They did agree that their first few batches were more miss than hit, and after getting into it more, they stared putting out better brews. One, they said, actually was a huge hit with their friends. Everyone wanted some. Word spread like wildfire, and they tried a second batch, and, according to their friends, missed it... Lightening doesn't always strike twice.
I'll get fresher yeast and possibly grains, and see what I come up with. I have to remember the teachings of my organic chemistry prof when I do it again. He was a stitch. A great man, but he was 'tight'.???
