G weasel,
aahhhhh i'd be kinda leary.... i'm not sure about mead, but as far as wine or beer goes, funky grey stuff growing on top of a primary or secencary ferment is not a good sign in my experience. if there was any rye in the process you might have some organic LSD going on. that could be good or bad depending on youre mind set. just say'n. i worked in a sub shop back in the early '80s and we used a certain rye pita bread that when it went moldy........yeeeeeehaaaaa fun with organic chemestry. c'mon gd~ help me out, youre the chemistry guy here.
