FrontStreet Coffee - Introduction to Coffee Processing Methods

Natural Processing Method

The natural process is the simplest and least expensive of the traditional ways to handle coffee beans. Harvested cherries are spread out on cement floors, brick patios, or mats and dried in the sun. They are raked frequently to dry evenly and to prevent fermentation, and if rain or falling temperatures arrive, the fruit must be covered to keep it from spoiling.

Once processing is complete, the moisture content of each fruit drops to roughly 12%. At this stage the cherries are dry. In Brazil, coffee at this point is called "coco." The skin turns dark brown and brittle, and you can hear the beans rattling inside their shells.

The process actually takes considerable skill. Over-dried beans are easily damaged during hulling, while under-dried beans are just as prone to damage.

Natural processing is common in Ethiopia and Brazil, and most Arabica beans have historically been handled this way.

Honey Process

The honey process begins by floating and sorting the cherries to remove unripe beans, other defective beans, and leaves, after which the coffee is processed as red, yellow, or black honey depending on the region.

Typically, yellow honey has the most pulp removed—about 40%. Red honey removes 25% of the pulp, while black honey removes only the skin. Fermentation follows. Once the desired degree of fermentation is reached, the beans are dried on drying machines or under direct sunlight.

Washed Process

The washed process demands greater capital and more labor, but it helps safeguard bean quality and reduce damage.

The key difference between the dry and wet methods is that in wet processing the pulp is separated from the beans immediately, rather than being left to dry on the bean as in the natural method.

Wet processing is applied to freshly picked cherries. The pulp is removed straight away—the shorter the interval, the better—and the beans are then soaked in water for 12-36 hours. This softens the mucilage so it can be washed away easily. The beans are then sorted, selected, and dried in the sun.

Knowledge Point: The honey process is divided into three types: yellow honey, red honey, and black honey.

FrontStreet Coffee Recommendation

Brazil is a great place to taste how processing shapes flavor, since its pulped natural (semi-washed) method sits between the natural and washed styles. If you simply want a first look at the Brazilian profile, FrontStreet Coffee's Brazil Cerrado Red Bourbon is a classic single-origin Brazilian bean. Cerrado is a well-known local region prized for high-quality coffee, and this lot is the common South American Red Bourbon variety. Given a medium roast, it opens up with creamy peanut, toasted bread, caramel, and hazelnut, a round and smooth cup with no sharp acidity and just a light bitterness. It works not only for pour-over but also for the moka pot, espresso SOE, siphon, and French press.

FrontStreet Coffee's Brazil Queen's Estate Yellow Bourbon comes from Mogiana, close to South Minas, where fertile red volcanic soil helps the fruit take in abundant nutrients and develop a full aroma. The variety here is the rare Yellow Bourbon, a natural mutation of Red Bourbon whose fruit character is cleaner, and the cup reveals a sugarcane-like sweetness found in few other regions, alongside fruit and chocolate notes; it can be brewed as pour-over, in a moka pot, or on a home espresso machine.

Because low acidity, balance, and an accessible price make Brazil a favorite base for espresso recipes, it also features in FrontStreet Coffee's espresso blends—the rich-crema Classic Blend, the nutty Premium Blend, the balanced Black Cocoa Blend that baristas recommend, and FrontStreet Coffee's Commercial Blend built for cafes. Adding Brazilian beans contributes chocolate and cream aromas along with a soft sweet-sour-bitterness that keeps extraction stable.
