Maceration
Softening whole coffee cherries by soaking them in liquid (their own juice, water, or a controlled solution) before or during fermentation — a term borrowed from winemaking that overlaps heavily with carbonic maceration and anaerobic whole-cherry methods.
'Maceration' in coffee is not standardized and overlaps with carbonic maceration, anaerobic whole-cherry fermentation and mosto methods. Any maceration claim needs the producer's specific protocol to be meaningful.
In food science, maceration means softening material by soaking it in liquid. In coffee, producers use it for whole cherries held in liquid — often their own expressed juice — as part of a controlled fermentation stage. It's closely related to (and overlaps with) carbonic maceration; the boundary between the two is not standardized.
Whole cherries sit submerged or sealed with their own expressed liquid for a defined period. The liquid environment controls which microbes work (low oxygen, sugar-rich) and the cherries soften as fermentation proceeds. Producers then continue to washed, natural or honey processing.
Like carbonic maceration: soft, deep, fruit-forward cups with round acidity — wine-like and juicy.
Borrowing wine language signals precision fermentation; the method itself offers a soft, controlled whole-fruit ferment.
Round, juicy, wine-and-fruit profiles similar to carbonic maceration — smooth acidity, soft body, deep fruit.
Sits between two better-defined methods; ambiguous labeling can confuse buyers. Process risk profile matches sealed-tank whole-cherry fermentation (over-ferment, mold, unrecoverable batches).
Nothing, unless the maceration liquid is an added fruit product — which would make it a mosto or fruit co-fermentation and require disclosure.
No flavoring is involved in plain maceration.
Producers in wine-coffee crossover style programs, mainly Latin America.
Colombia, Ecuador and neighboring microlot scenes.
Lots described as 'maceration' on roaster pages usually turn out to be sealed whole-cherry ferments — we verify per producer.
