CU✨all pellicles are SCOBYs✨but not all SCOBYs make a pellicle. Sounds like a riddle, but it’s a fact 👏
While the pellicle is a recognizable sign of a healthy fermentation, the SCOBY resides in the floating cellulose layer AND the liquid kombucha.
Kombucha SCOBYs are symbiotic colonies of bacteria and yeast that work together to ferment sweet tea into the tangy, probiotic-rich drink we love.
The gelatinous structure of the SCOBY, the pellicile, is a polysaccharide matrix, primarily built by Acetobacter. These bacteria secrete the compounds that give it its firm, rubbery texture. So when you ask, “What is a SCOBY?”—the honest answer lies in the microbes that create, sustain, and live within it.
Let’s look at the microorganisms that make up this living colony.
A healthy kombucha culture typically includes Pediococcus, Saccharomyces, and Acetobacter species, each playing a role in fermentation, acidity, and carbonation. Many SCOBYs also house microbes from the Zygosaccharomyces, Schizosaccharomyces, and Komagataeibacter genera, contributing to fermentation and flavor complexity. Some SCOBYs even contain Lactococcus, Leuconostoc, and Lactobacillus species, though these typically comprise only a tiny portion of the microbial community.
Each kombucha batch has its unique microbial fingerprint, shaped by the environment and fermentation conditions, making every brew a little different. (reference articles linked below recipe card in the blog post)
