Differences Between Natural and Washed Coffee Beans: Yirgacheffe Coffee Flavor Description, Processing Method, and Grind Setting Introduction

The Difference Between Sun-Dried and Washed Coffee Beans - FrontStreet Coffee's Yirgacheffe Flavor Description, Processing Method, and Grind Setting Introduction

The honey processing method is susceptible to contamination and mold, so it requires constant monitoring and continuous turning to accelerate drying and avoid undesirable fermentation flavors. Its advantage is that it preserves the original sweet flavors of ripe coffee cherries, giving the coffee delicate brown sugar notes and a nutty sweetness, while berry flavors support a red-wine-like aromatic base, making it an exceptionally elegant product. Coffee beans processed this way have become very popular largely because their sweet, full-bodied character suits espresso preparation in cafés. In recent years, more coffees marketed as "Miel Process" have appeared, and they have become preferred material for international coffee competition participants.

So-called honey processing (Miel Process in Spanish) refers to drying the raw beans with their mucilage still intact. After the outer pulp is removed from the coffee beans, a layer of viscous, gelatinous substance remains. The traditional washed method uses water to wash this away, but because some high-altitude growing regions are short of water, this direct-drying method emerged. The process involves spreading coffee cherries across drying fields for two weeks, raking them several times a day to ensure even drying. Once dry, the beans separate from the outer skin, and hulling machines remove the dried pulp and fruit skin, followed by screening and sorting into grades. Because the drying method needs good weather and space and has some limitations, it is rarely used exclusively; many places combine drying and washing, commonly known as semi-washed processing.

Washed Coffee

Washed coffee accounts for 35% of exports. High-quality washed coffee uses freshly picked, fully mature fruit, with careful harvesting and strict monitoring by professionals. After selection and cleaning, the beans are depulped on the same day as harvest, then fermented, washed, dried and hulled. The processed beans hold a moisture content of around 12%. The washed method yields good body, high aroma and lively acidity.

Sun-Dried Coffee

Sun-dried coffee accounts for 65% of exports. It is mainly harvested by families, with red coffee cherries placed on cement floors or raised tables to dry to approximately 11.5% moisture content, then hulled and cleaned. Sun-dried beans possess complete natural body, a gentle aroma and more gum content.

FrontStreet Coffee Recommendation

Processing method is one of the clearest ways to taste how a single region can shift, and Yirgacheffe is the perfect case study. FrontStreet Coffee's Washed Yirgacheffe is the classic everyday lot and the coffee most drinkers try first: white jasmine, bright citrus and lemon acidity and a clean tea-like body, at a price that makes moving into specialty coffee an easy step. Yirgacheffe is a small town in southern Ethiopia's Sidamo province at roughly 1,700-2,100 meters, with the trees planted above 1,800 meters, among the highest coffee-growing areas in the world. In 2010, once the name had become so famous, the Ethiopia Commodity Exchange separated Yirgacheffe from Sidamo as its own region.

Within the town there are many smaller areas and villages, and several have experienced cooperatives whose refined processing lifts the flavor higher. The best example is FrontStreet Coffee's Washed Gordin Cooperative, in the Worka area at the southeastern edge of Yirgacheffe. It began as part of the Worka cooperative under the Yirgacheffe Coffee Farmers Cooperative Union (YCFCU), and as demand for traceable green coffee grew it was excavated as a single-origin lot by coffee hunters around the world. It follows the most traditional washed processing, and the result carries none of the usual bitterness — clean, bright citrus and lemon acidity with jasmine fragrance and an elegant white floral character.

FrontStreet Coffee's Red Cherry shows what the other side of the divide tastes like. It is a whole-cherry natural: only fully ripe, sound cherries are harvested, screened a first time at the mill, then spread directly on raised beds. In the first few days they are turned every 2-3 hours so they never overheat or over-ferment, and after three to five weeks of sun-drying the pulp is machine-scraped and the beans go into storage. Drying with the fruit still on the bean preserves the typical Yirgacheffe profile while adding a tropical fruit character from the natural process: citrus-like acidity, berry-juice body, honey sweetness and a creamy smoothness. FrontStreet Coffee brews these lots in a V60 at 90-91°C, using 15g of coffee with a 1:15 ratio and a grind of EK43s setting 10 — about fine-sugar size, or 80% passing a No. 20 sieve — with a 30g bloom for 30 seconds, then 95g to about 125g over roughly a minute, and the final 100g to about 225g, finishing the drawdown in 2'00"-2'10".
