Ugandan Bugisu AA Coffee-A thick, low-sour coffee

Uganda is a landlocked country in eastern Africa, straddling the equator, bordering Kenya to the east, Tanzania and Rwanda to the south, the Democratic Republic of the Congo to the west and Sudan to the north. Most of the territory is located in the Central African Plateau, many lakes, with an average elevation of 1000,000,1200 meters above sea level. There are many lakes and plateaus in the mountains, which are known as "plateau water villages". The western branch of the East African Rift Valley runs through the western border, with many rivers and lakes at the bottom of the valley. Uganda has a great Victoria lake, coupled with the high mountains, which makes Uganda a mild climate suitable for growing coffee, although it spans both sides of the equator.

The coffee growing industry in Uganda is one of the pillar industries of its exports. Uganda is the birthplace of Robsta in Africa, just as Ethiopia is the origin of Arabica coffee, which was first discovered in Uganda. So far, Uganda has a history of growing coffee for more than 100 years. The output ranks second in Africa, after Ethiopia. At the same time, Uganda is one of the few major countries in Africa dedicated to the production of organic coffee. In Uganda (Uganda), Arabica coffee beans account for only 15% of the country's total coffee production, and Uganda's best coffee is mainly produced in the mountains of Elgon and Bugisu along the Kenyan border in the north-east and Ruwensori in the west.

The cultivation of coffee in Uganda is all small-scale family operation. The livelihood of 25% of the population is closely related to coffee production. About 500000 farms grow coffee, but mainly Robster. Robster accounts for 90% of coffee production, and the remaining 1 is Arabica coffee. Arabica and Live Buster are harvested from October to February of the following year. The main sales areas and quality grades of Ugandan coffee are: Bujisu Bugisu AA (accounting for only 4% of the total national production), Bujisu Bugisu A, Vago Wugar A (all of the above belong to water washing treatment), and a small amount of sun-dried bean beads Drugar. Bugisu Bugisu AA. Among them, AA represents the grade of coffee and represents the highest grade in the country. Bugisu Bugisu grows on the slopes of Mount Elgon in eastern Uganda. The palate is thick and low in acidity, with a unique taste of raw papaya, which is very different from other East African coffee, closer to Java coffee in Indonesia.

Uganda leads Africa in coffee production, accounting for more than 70% of its total exports. In the 1960s, Ugandan coffee production remained at 3.5 million bags a year. By the mid-1980s, coffee production had dropped to 2.5 million bags a year, mainly for political reasons. But now coffee production is on the rise again, currently about 3 million bags a year. It is mainly exported to the European Union, with Germany, Italy and other countries as the largest coffee buyers.
