A symbiotic culture of bacteria and yeast; the rubbery, gelatinous mass used to ferment kombucha tea and other beverages.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as просто 'гриб' ('mushroom/fungus') which is too broad and misleading; it's a specific bacterial-yeast culture.
- The acronym SCOBY is often used untranslated in Russian niche texts.
Common Mistakes
- Mispronouncing as /ˈskɒb.i/ or /ˈskəʊb.i/ (two syllables, not three).
- Using it as a plural (scobies is the standard plural).
- Confusing it with the finished drink (kombucha is the drink; scoby is the culture that makes it).
