Hey everyone, I just joined this community and I am a beginner kombucha brewer. This is my second batch and my first came out great. However, I'm not sure how the scoby is supposed to look really and this struck me as a little odd.
There's a big dark spot beneath a bubble to the right. My last scoby was pretty much completely white after about 10 days. This doesn't appear to have any mold on it or anything like that and the scoby generally looks good, but I'm concerned about the dark area. It looks like a big bubble, but I'm not sure why it would be dark.
Any ideas on what this could be and if my kombucha is safe to drink or not? It's currently been brewing for a little over a week.
