Kombucha SCOBY Sinking: Explanation for the Unexpected Submergence of Symbiotic Culture of Bacteria and Yeast in Fermented Tea
Chilling with Your Homemade Kombucha
You've stumbled upon your homemade kombucha, and you discover the kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast) nestled at the bottom of the jar.
Relax, it's all good! A new SCOBY will soon emerge on the jar's surface.
Now that you're feeling relaxed, let's delve into why your kombucha SCOBY might (or might not!) wind up at the bottom, and what to do if it does.
Why's My Kombucha SCOBY at the Bottom?
A kombucha SCOBY is a cellulose structure crafted by microorganisms floating on the surface of the sweet tea. This film is essential for bacteria, offering them the direct contact with the oxygen they need to thrive. During fermentation, CO2 bubbles assist in keeping the SCOBY at the surface.
However, with a younger SCOBY, the CO2 production may not be robust enough, causing the SCOBY to hang out at the jar's bottom. Yeast colonies require a few rounds of brewing before they grow strong enough to create enough CO2 to keep the SCOBY afloat. So, don't sweat it – everything's normal!
What to Do if My Kombucha SCOBY is AWOL?
Your kombucha SCOBY dipped below the surface? No worries! Just leave it alone and catch some zzz's.
After a few days, a new SCOBY will pop up on the liquid's surface, resembling the jar's mouth.
The disappearing SCOBY might resurface as gas forms in your kombucha or continue to hang out at the bottom of the jar. Either way, it's a sign of healthy fermentation!
SCOBY's Location: Does it Matter?
When it comes to kombucha SCOBYs, people often picture the solid, gooey parts. But it's the bacteria and yeast residing in the film and the kombucha that really matter.
The SCOBY added to sweet tea performs two essential functions:
- Offering needed microorganisms to turn the tea into kombucha.
- Creating an acidic environment to prevent mold growth.
These functions can be accomplished by the starter liquid culture, aka the liquid the film is soaking in. It's just plain kombucha!
The starter culture houses all the bacteria and yeast needed to ferment the sweet tea and is acidic enough to ward off external contamination[3]. As a result, the position of the kombucha SCOBY in your jar is inconsequential.
What's truly significant is having enough starter liquid culture. A new SCOBY will always gradually emerge in a healthy kombucha.

Enrichment Data:- SCOBY Sinking Reasons: + Healthy Fermentation: The SCOBY sinking can be a regular part of the fermentation process, as new layers of the SCOBY form on the surface and older layers detach[2]. + New SCOBY Formation: The presence of free-floating bits or new layers forming on the surface indicates an active, healthy fermentation, with the sinking of older layers being part of the process[4]. + Environmental Factors: Temperature fluctuations, contamination, or the composition of the sweet tea could influence the SCOBY's behavior. However, these factors are less likely to cause sinking unless they are extreme[3].- SCOBY Sinking Concerns: + Generally Not: If your kombucha tastes and smells good, with no mold or off-odors, the SCOBY sinking isn't a concern[2][4]. However, be mindful of other potential signs like mold, strong off-odors, or discoloration[3]. In such cases, it may signal a problem with the fermentation environment or contamination.
Your homemade kombucha SCOBY might find its way to the bottom due to a younger SCOBY's inadequate CO2 production, or because of new SCOBY formation on the surface, which is a sign of healthy fermentation. Regardless of the SCOBY's location, the bacteria and yeast in the film and the kombucha are what truly matter.
