Ethiopia's washed processing technology was introduced from Central and South America in 1972. The washed process is complicated and tedious, and requires a large amount of clean water, so its cost is higher than the natural method, and it is also less commonly used in water-scarce African regions.

Washed steps: after coffee cherries are picked, they are put into water, and buoyancy is used to pick out underripe fruits; then a depulper is used to remove the skin and pulp, and they are left to rest in a fermentation tank for 18 to 36 hours until the mucilage layer breaks down. After fermentation is complete, the parchment beans are scrubbed in channels for 30 to 60 minutes; through specially designed channels combined with flowing water, low-density and poor-quality beans are removed, then the high-quality coffee beans are drained of water and spread on African raised beds to dry.

Because the pulp is removed before drying, Yirgacheffe's own inherent aromas are displayed more clearly, presenting citrus and lemon notes and elegant white floral aromas, with an overall bright and delicate flavor.

After two weeks, the sugars and essence of the pulp have all penetrated into the coffee beans, and the moisture content drops to 12%; then the hardened pulp, mucilage layer, and pod are all scraped clean together by a depulper, and after the coffee beans are removed, they still need to undergo density and bean-color testing. After eliminating defective beans, workers finally remove any missed defective beans by eye, with layer upon layer of quality control, creating the clean and refined character of Yirgacheffe natural beans.

The biggest difference between washed processing and natural processing is that washed processing first removes the coffee skin and pulp, then puts the beans into a clean water tank to ferment, removes residual mucilage, and then sun-dries them, so washed coffee beans have a shorter drying time, a cleaner overall flavor, and more obvious acidity.

Natural processing, on the other hand, keeps the skin and pulp and sun-dries the whole cherry directly. At high temperatures, the sugars in the pulp ferment, so the coffee beans absorb these fermentation aromas, and at the same time the sugars in the pulp are transferred to some extent into the beans, so naturally processed coffee beans have a faint fermented aroma and a more obvious sweetness.

V60 dripper, water temperature 91~93°C, coffee-to-water ratio 1:15, dose 15g, grind size (80% passing through a Chinese No. 20 standard sieve)

Use staged extraction, first blooming with water at 2 times the coffee dose, that is, 30 grams of water for a 30-second bloom. The purpose of the bloom is to let the coffee grounds release internal carbon dioxide, thereby making the later extraction more stable. Pour in a small stream in circles until 125 grams, then pause, continue pouring until 225 grams and stop; after the water in the dripper has dripped through, remove the dripper, and timing from the start of pouring, the extraction time is 2'00".
