is this mold?
I went to check on my kombucha today (after 12 days in dark and warm place in a cupboard above my fridge)and I found that my SCOBY had floated up to the surface and had these dark spots on it. Is it molded?
Likely not. Mold will be FUZZY on top and usually white or green, or green + white splots. Dark spots on a SCOBY is likely the yeast.
