I had a batch of Kombucha go bad after neglecting it for some months. My roomates dog got in there for a second after she removed the protective towel on the top but I caught her righ away.. I should have just thrown it out but it was so fresh and pretty at the time. Anyway, later I swear I saw somthing wiggling in it which is when I though it out. I wonder what kind of strange things were growing in there??? Maybe Shroom knows.
