Scoby

a symbiotic culture of bacteria (such as Komagataeibacter xylinus synonym Acetobacter xylinum) and yeasts (as of the genera Brettanomyces and Saccharomyces) in the form of a gelatinous film which results from the fermentation process that produces kombucha and is typically reserved and used as a starter (see STARTER entry 1 sense 3b) to make more batches

At the beginning of 2021, Romy Ellenbogen … got a kombucha starter kit in the mail. Every time she brewed a batch, her SCOBY doubled.
