Natural (In-Cherry) Fermentation

Fermentation that happens inside the intact cherry. Instead of removing the fruit first, the producer dries the whole cherry — usually on raised beds or patios for 12-30 days — while the sugars and microbes inside the fruit ferment against the seed the entire time.

As the cherry dries, its sugars fuel fermentation by yeasts and bacteria on and inside the fruit. The seed sits in contact with fermenting fruit sugars for days or weeks, absorbing aromatic compounds. Careful turning and even drying prevent mold and over-fermentation.

The seed takes on fruit sugars and fermentation aromatics — a heavier body, lower perceived acidity, and intense fruity or winey flavors compared to washed coffee.

It requires no water and minimal equipment — vital in dry regions like Brazil and Ethiopia — and it produces the distinctive flavor profiles that have made naturals award-winners and best-sellers.

Strawberry, blueberry, tropical fruit, wine, chocolate — intense, sweet, syrupy, with a heavier body and softer acidity than washed coffees.

Uneven drying causes mold and 'ferment' defects; over-ripe or damaged cherries introduce harsh fermented, musty flavors. Naturals are less predictable than washed lots, which is why careful cherry sorting matters so much.

Nothing — only the coffee's own fruit and naturally present microorganisms.

All 'fruit' flavor comes from the coffee's own cherry fermenting against the seed. Nothing is added; it is not flavored coffee.

Most producers in Brazil and Ethiopia; a growing specialty-natural movement in Colombia and Central America.

Worldwide, but historically dominant in Brazil, Ethiopia, Yemen and other regions with dry harvest weather.

Classic Ethiopian naturals (Sidama, Yirgacheffe natural lots) with their famous blueberry notes; Brazilian naturals that anchor most espresso blends.
