How to tell if your kombucha SCOBY is bad? Can it go bad or die?
A healthy SCOBY is white and can have brown or black streaks from tea and brewing process. Your SCOBY has gone bad if it is moldy and there is no mistaking it when you see it. The mold will be white or colorful, fuzzy and dry. It can appear as spots or cover it altogether. A dead scoby will be black.
