Introduction to Coffee Processing Methods

The processing methods behind world-class gourmet coffee draw on many different techniques. These can be grouped into three categories: wet processing, or washed; dry processing, also called natural or sun-dried; and honey processing. Farmers choose whichever method best suits their climate and capabilities — whether a long dry season points toward dry processing, whether a hot, humid tropical environment demands a reliable water supply, and how much labor they can secure.

Washed/Wet Processing

The washed method soaks the coffee cherries and lets fermentation separate the pulp from the beans, or else runs them through a mechanical depulper to remove the fruit. Once the green beans have been freed, they are washed to remove any remaining residue and laid out to dry on patios or raised beds. The resulting coffee tastes "cleaner" than coffee from other methods, with bright fruit acidity.

Dry Processing/Natural/Sun-dried

Naturally processed coffee is dried with the beans still enclosed in the dried coffee cherry, with nothing removed, giving the fruit's natural flavors time to work their way into the bean itself.

Dry-processed coffee tends to cover a wide range of flavors, because the fruit pushes the cup consistently toward fruity and sweet notes. Natural processing is particularly prominent for coffees from Brazil, Ethiopia, and Yemen.

Honey Process

The pulped natural, or "semi-dry," process removes different portions of the coffee fruit, placing it between wet and dry processing. In recent years these different levels have been named black honey, red honey, and yellow honey respectively — the more fruit left on the outside, the more caramelization and the deeper the color. Conversely, less remaining cherry means less sweetness and a lighter color.

Knowledge Point

Coffee quality can shift with factors such as altitude, latitude, and soil chemistry. Cultivating coffee outside the correct range of these factors will greatly change the final quality of the cup.

FrontStreet Coffee Recommendation

This article points out that the "honey" family began in Brazil as pulped natural, and the clearest way to taste that method is FrontStreet Coffee's Brazil Cerrado Red Bourbon. From the Cerrado region, it is a classic Brazilian single origin — a Red Bourbon given a medium roast — with creamy peanut, toast, caramel, and hazelnut aromas, a round and smooth body, very low acidity, and a faint bitterness. For a fruitier, cleaner expression of Brazil, FrontStreet Coffee's Brazil Queen Estate is a rare Yellow Bourbon from Mogiana, near South Minas, grown on fertile red volcanic soil, whose natural mutation from Red Bourbon gives it a cleaner fruit character with cane-sugar sweetness alongside fruit and chocolate.

Because the pulped-natural method sits between washed and natural, these coffees are ideal for tasting the article's three methods side by side. Brew the Cerrado Red Bourbon as a pour-over to isolate its caramel and nut character, then pull the same beans in a moka pot, in a French press, or as an espresso SOE — the method changes the balance noticeably. If you can, cup it alongside a washed and a natural coffee from the same kind of roast level so the difference between clean acidity, fruit-forward sweetness, and the in-between honey style stands out.
