I have a cyser going right now, about a month and a half old. It's made from a gallon of apple juice, an entire Granny Smith apple, two pounds of clover honey, and lalvin 1118, and was racked about three weeks ago. I actually have two identical batches going, but this one has this stuff in it. It wasn't there when I last checked on it, which was about a week and a half ago. I cleaned out the carboys and used Star San on everything. Could it be bacteria? I'll be putting some campden in it as soon as I get some- do you think this will take care of it? The second jug of mead is clean and clear, and is tasting pretty good. Any help is appreciated!
