/diy/ - Do It Yourself

lads, I've done goofed up, left my brew in the bucket for a couple of months, also, it had a ginger in hopsack hanging off the side, I think it was just enough to leak some crap in

I've had brew with bad floaters before, I was careful and trying to bottle it, taking liquid only from below and discarding a good portion, but even then this stuff is apparently forming inside the bottles, I've tasted it and it didn't seem off (not great tho)

question is, besides being shit, does this stuff actually pose any danger, is it actual fungus?
