My first batch of kombucha got moldy last Tuesday
I had it going for about 8 days in a big glass jar on the counter. The SCOBY looked fine, but I saw a fuzzy blue spot on the surface when I checked it. I was so bummed. I poured the whole thing out, cleaned the jar with hot soapy water, and started over with a fresh starter from a friend. Has anyone else had mold show up that fast, and what do you think causes it?

Read somewhere that mold that fast usually means the starter liquid wasn't acidic enough to protect it.

That tracks with what I saw on a kombucha forum last week. The pH needs to be under 4.5 from the start, or you're basically just leaving sweet tea out. A lot of recipes skip the vinegar step, which is a huge risk. If your starter isn't strong enough, mold shows up in days.
