Processing method

Double & Sequential Fermentation

This umbrella label describes coffee fermented in two or more deliberately differentiated stages. A producer might change the vessel, available oxygen, selected culture or other condition between stages. The name alone does not specify the sequence, length, fruit state or drying step. Multiple stages do not automatically create more complex or higher-quality coffee. Ask the producer to describe each stage in order and to disclose any added ingredients.

Illustrative flavor tendencies, not a lot-specific claim

No reliable general flavor prediction; sensory outcomes need lot-level evidence.

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.
