Three treatments of water washing, sun washing and semi-washing in Limu coffee producing area of Ethiopia

Ethiopia's coffee-producing areas are divided into east and west parts by the Great Rift Valley. Lakes, volcanoes, lowlands, plateaus and woodlands alternate and evolve independently. Ethiopia has the most diverse coffee ecosystem in the world (forest coffee, semi-forest coffee, pastoral coffee and plantation coffee), which also allows it to preserve its rich Arabica genes. The eastern half is mostly plateau, coffee beans taste better, such as yejia sherphine and sidamo, which are popular with bright sour taste, and Hailiar with charming "mixed fragrance"; the western half is covered with large areas of virgin forest, mostly in complete natural evolution, creating more complex coffee varieties, and the coffee varieties in the southwest Kafa forest have strong disease resistance. Due to natural evolution and less artificial selection, its overall flavor is slightly inferior to that of East Banbi.

Ethiopia's coffee producing regions are Sidamo, Harrar and Yirgacheffe. Sidamo and Harrar are provinces and divisions. Sidamo is located in the south of Ethiopia adjacent to Kenya. Harrar borders Somalia in the east of Ethiopia. Although Yirgacheffe is a small area in Sidamo region, due to soil composition and water content, its coffee production is considered to be the best in Ethiopia.

Limu grows in the south-western highlands of Ethiopia. East of Gima, north of Sidmo, elevation 3600-6200 ft. Preferred by most Europeans and Americans, mostly washed, annual yield of about 110000bags/60kg, medium mostly round (15/16scr), color green with blue, exports are mostly G2 grade, taste similar to Yegashev, viscosity is thinner, but floral and fruit flavor is obvious, sour is also softer than Yegashev, more irritating acid, residual taste similar to wine, has a very good and balanced quality, suddenly heard that this is more suitable for air-flow medium baking, not suitable for deep baking, baking after the better flavor for two to three days. It is the only fine coffee producing area in the west half of the wall, with less output, mainly exported to European and American markets, and rare in Asia. There are washing, sun and semi-washing three kinds of treatment, in Europe and America, washed rum ranked second only to Yerga Sherphine. The flavor spectrum of Lime is different from that of Sidamo and Yegachephine. The viscosity is obviously lower. The performance of flower fragrance and citrus acid is also inferior to Yegachephine and Sidamo, but there is an extra fragrance of grass and brown sugar, and the fruit acid is bright.
