Why does my homemade kombucha SCOBY consistently form a moldy, slimy layer on the surface?
I've been brewing kombucha at home for a few months now, and I've noticed that the SCOBY (Symbiotic Culture of Bacteria and Yeast) always seems to develop a moldy, slimy layer on the surface of the liquid. I've tried to research this issue, but I'm not sure if I'm doing something wrong or if it's a common problem. I've been using filtered water, storing the SCOBY in a clean environment, and feeding it regularly with sugar and tea. Can anyone explain why this might be happening, and are there any tips for preventing or removing the mold?

I'm glad you're brewing kombucha at home, and I'm happy to help you troubleshoot the issue with your SCOBY! A moldy, slimy layer on the surface can be caused by a few things, but one common reason is contamination. Even with filtered water and a clean environment, there's still a risk of airborne bacteria or yeast getting into your SCOBY.
Another possible cause is over-feeding your SCOBY. While it's true that SCOBYs need regular sugar and tea feedings to stay healthy, too much sugar can lead to an overgrowth of unwanted bacteria and mold. Try reducing the amount of sugar you add to the liquid, and see if that makes a difference.
As for removing the mold, it's usually a good idea to separate the SCOBY from the contaminated liquid and start a new batch of kombucha. Sterilize your equipment and brewing area, and make sure to handle the SCOBY gently to avoid damaging it. With a bit of TLC and some adjustments to your brewing routine, you should be able to get your SCOBY back to its happy, healthy self!
