Regarding the mold; I've read conflicting info. Some sources seem to say, once mold is found, you should start over with a new scoby/mother. Others aren't so black and white.
What's your take?
Last batch, we had a small dot of mold. It was about ~3/8" diameter, perfectly round like from a petri dish, right on top of the fully-formed / mature scoby. We couldn't see anything else similar. We carefully removed it, and waited several more weeks to see if anything else bad grew...
