The Traditional Natural Processing Method

Coffee cherries must be processed immediately after harvest, or the pulp ferments and rots.

There are three common ways to process green coffee: natural (dry), washed, and honey. Each leaves its own fingerprint on the cup — today we start with the traditional natural method.

Process Overview

● Float-sorting — Drying — Hulling — Grading — Polishing

Natural processing is also called the "sun-dried method" because both the cherry and the green bean are dried entirely by natural sunlight. Since it relies on manual, low-intervention handling, natural-processed beans look less uniform and less polished than washed ones.

The Steps in Detail

1. Bean Selection

The harvested cherries go into a water tank. Mature fruit sinks; unripe and overripe cherries float and are skimmed off.

2. Drying

The cherries are spread out to sun-dry for 2-3 weeks, turned several times a day until fully dried. By then the fruit has turned dark brown, and the moisture content should sit between 10%-14%.

3. Hulling

Once dried, the fruit skin becomes brittle and easy to strip off by machine. Commercial farms usually own their own hulling facilities; small farms send their lots to central processing mills.

4. Selection and Grading

Quality-focused farms identify and remove defective beans by hand or machine. Manual sorting typically runs beans along conveyor belts about 1 meter wide, with sorters seated on both sides picking out bad beans by eye — the best farms repeat the pass until no defects remain. Machine sorting uses optical recognition to eliminate defects, after which grading divides the beans into quality levels by established standards: good coffee heads to the specialty market, lesser coffee to the commercial market.

5. Polishing

Hulling removes only the exocarp and endocarp; the silverskin still clings to the seed and must be buffed off by machine. Then the beans are bagged — usually in burlap sacks.

Summary

Advantages:

Simple and cheap (especially in water-scarce regions). Done well, it delivers heavier body and higher sweetness, often with mature fruit flavors or wine-like aromas.

Disadvantages:

Heavily weather-dependent, so drying is hard to control. During sun drying, foreign flavors creep in easily, and since the pulp stays on, mold is a constant risk — stability suffers.

Recommended Natural-Process Coffee Bean Brands

FrontStreet Coffee's freshly roasted natural single origins — natural Yirgacheffe and natural Sidamo among them — carry full brand and quality guarantees and suit every brewing device. Better yet, they're excellent value: a 227-gram half-jin bag costs only about 70-90 yuan. At 200ml per cup with a 1:15 coffee-to-water ratio, one bag brews 15 cups of specialty coffee — just 5-6 yuan a cup, against the dozens of yuan a café charges.

FrontStreet Coffee Recommendation

If the natural method's fruit-and-sweetness appeal to you, honey processing is its refined cousin — and worth exploring. Honey evolved from the semi-dried (pulped natural) method: depulp the cherry, then dry it with some or all of the mucilage still attached, shortening drying time while avoiding the off-flavors of careless fermentation. Brazil's classic semi-dried coffees (FrontStreet's Cerrado, with its cream, peanut, nut, and chocolate notes) inspired Costa Rica to refine the approach into honey processing, graded by how much mucilage remains — black, red, yellow, and white honey. Two FrontStreet Coffee honey-processed picks:

FrontStreet Costa Rica Blackberry (black honey) — black honey removes almost none of the mucilage, so drying takes at least 2 weeks under shading covers that slow the sun and ensure the sugars fully convert, with regular turning to prevent uneven heating and over-fermentation. It demands the most labor of all honey methods. Roasted medium-light, the grounds release a dense fresh-floral aroma, and the cup carries the special flavors of grape, berry, and ripe blackberry.

FrontStreet Costa Rica Mozart (raisin honey) — an inventive upgrade beyond the traditional yellow-red-black honeys: the whole cherries are pre-dried on raised beds for at least 3 days before the skin and pulp are removed and the honey process continues, keeping 100% of the mucilage. That makes raisin honey even trickier than black honey — timing must be exact — but it rewards you with richer dried-fruit sweetness. Brew it as pour-over, cold brew, or moka pot and you'll find osmanthus, pineapple, and raisin aromas in every cup.
