Natural Processing: A Traditional Coffee Bean Primary Processing Method

The natural method is one of the traditional primary processing methods for coffee. To this day, ancient coffee-growing countries like Ethiopia and Yemen still process the vast majority of their beans naturally.

In natural processing, sink-sorted beans—whether fully or semi-mature—are spread directly onto drying grounds and left to dry in the open air.

Dry Processing (Secado)

Also known as the full natural method, this means drying harvested coffee cherries whole in the sun. Depending on the weather, it generally takes 1–2 weeks to bring the beans' moisture content down to 10%–12%, after which machines strip off the dried skin and pulp. During storage, processing plants (beneficios) usually leave the parchment shell on the beans until just before export (Costa Rican law, notably, requires that exported green coffee be shipped without parchment). This method demands a producing region with plenty of reliable sunshine.

Requirements and Characteristics of Natural Processing

Natural processing is extremely demanding on climate: if rain falls during drying, the beans can reabsorb moisture and mold. Raw natural beans are yellowish in color, and after roasting the center cut appears brown rather than the white center cut typical of washed beans. In the cup, naturals generally offer better sweetness and body with less acidity, but quality is comparatively unstable and varies considerably. Because natural processing costs so little, it remains widespread not only in Ethiopia and Yemen but also for Robusta grown across Africa and Indonesia.

The method has existed for centuries in Ethiopia and Yemen. It wastes very little water or electricity, but producing high-quality natural coffee requires substantial time and labor to separate out immature and defective beans.

After harvest, cherries go straight onto drying grounds. The process can take up to a month and demands constant observation and turning to prevent over-fermentation, spoilage, and uneven drying.

Alternatively, coffee can be dried on African beds—net racks raised off the ground. The advantage here is more even drying and protection against spoilage.

Once drying is complete, the cherries pass through stages that remove the dried skin, pulp, and inner parchment.

Advantages and Disadvantages of Natural Processing

Benefits of natural processed coffee: When done properly, it delivers unimaginable sweetness, balance, and mature fruit flavors.

Disadvantages of natural processed coffee: Because large quantities of cherries are turned and screened together, a single mistake can ruin an entire batch.

General characteristics of natural processed beans: Expect abundant fruit, spice, and chocolate notes. When processing goes wrong, however, the cup turns dirty with muted acidity. At their best: rich fruit flavors (berries, cherry, tropical fruit), spice, and cocoa.

FrontStreet Coffee's Natural Processed Coffee Bean Recommendations

FrontStreet Coffee's freshly roasted single-origin natural process beans—such as Natural Yirgacheffe and Natural Sidamo—are dependable in both brand and quality and brew well on any equipment. Better still, they offer outstanding value: a half-pound (227g) bag costs only around 70–90 yuan. At 200ml per cup with a 1:15 coffee-to-water ratio, one bag brews 15 cups of specialty coffee, working out to roughly 5–6 yuan per cup—far below the dozens of yuan a café charges, and perfectly suited to daily drinking.

For a showcase natural from Ethiopia, the birthplace of coffee and home to countless heirloom varieties, try FrontStreet Coffee's Natural Red Cherry lot from the Yirgacheffe Cherry Project. With natural processing, damaged or moldy cherries are removed first, then the rest dry in the sun for two weeks so the pulp's sugars and essence soak into the bean; once moisture drops to 12%, the hardened pulp, mucilage, and pods are scraped away, the beans pass density and color checks, and workers hand-pick any remaining defects—multiple layers of screening so that every bean is specialty grade: remarkably clean with an intense, captivating fruit character. Flavor notes: peach, cocoa, honey, and lemon.

For something even richer, FrontStreet Coffee's Natural Cherie (Huakui) comes from the Hambella region of Guji, Sidamo, on a 200-hectare farm using traditional natural processing. To keep the cherries from molding or picking up earthy odors, workers sun them on raised beds for 21 days, turning them constantly for even drying, and hand-sort out defective or moldy beans every three to five days. Because the beans dry with their pulp and skin intact, a medium-light roast reveals light fermented winey notes, florals, citrus, and mango—a denser, more complex cup with honey sweetness and a cocoa undertone touched by spice, full-bodied with a long finish.

FrontStreet Coffee Recommendation

Ethiopia deserves a closer look as the origin of these naturals. It is a world-renowned specialty coffee region, and as the birthplace of coffee it holds countless native varieties—a treasure land in the eyes of coffee lovers, whose flavors keep them coming back faithfully. Most Ethiopian coffee grows under a garden-farming model: each smallholder sends harvested cherries to a village-based processing station, and the lots sell under the name of the production team—which is why you see cooperatives of every size, such as the Guodingding Cooperative, the Worka Cooperative, and the Konga Cooperative that FrontStreet Coffee carries.

The Guodingding Cooperative sits in the Worka zone at the southeastern end of Yirgacheffe. Originally part of the Worka cooperative under the YCFCU union, it became independent in 2012 with about 300 member farmers as the world's coffee hunters dug out one traceable "single zone" after another. Because the pulp is stripped before drying, Guodingding's coffee shows its inherent character with unusual clarity: citrus and lemon tones, elegant white florals, and a bright, delicate profile overall. For a wilder expression, FrontStreet Coffee's Kafa Forest lot comes from truly wild coffee trees growing at 1,400–2,100 meters under forest shade, where primeval ecology, microclimates, red earth soil, and plentiful rain create ideal growing conditions; at a medium-light roast it offers distinct white florals, bright lemon acidity, sweet orange and bergamot flavors, and a green-tea-like cup with faint melon-and-nut sweetness in the finish.
