Yeast-Inoculated Fermentation
Yeast-inoculated fermentation means a producer deliberately introduces a selected yeast culture during post-harvest processing. Results depend on the particular strain, dose, time, temperature, oxygen conditions and coffee. Research shows sensory outcomes can change, but a selected yeast does not guarantee sweetness, fruitiness, greater consistency or a higher quality score. Ask which starter culture was used and whether the producer documented the process.
What this processing label does not prove
The method name alone does not establish ingredients, fermentation time, microorganisms, drying conditions, farm identity or cup quality. Ask for a documented producer or roaster protocol before treating those details as facts.
These references support the general method description, not a particular producer’s undocumented recipe or cup score.
