A healthy SCOBY will display a firm, jelly-like texture with a light beige to brown hue. Bubble formation and the potential growth of a new layer on the existing SCOBY are indicators of ongoing fermentation. If you're uncertain about its health or activity, send us a message with a photo, and we'll troubleshoot with you. If the SCOBY presents mold, discoloration, or an unpleasant odor, it might be compromised.
