Qianjie-A brief introduction to the coffee grading system and development history of Kenya

Coffee has been recorded as early as the 8th century, cafes were also popular in the 17th century, and its neighboring Ethiopia is known as the country of origin of coffee, but coffee only entered Kenya in the 19th century. it was only at the beginning of the 20th century that coffee was grown, but now Kenya has become one of the leading producers of fine coffee in the world.

Originally-coffee was grown on large estates under British colonial rule; harvested coffee beans were shipped to London for sale. The Coffee Act of 1933 was passed and the kenya Coffee Committee was established, which transferred coffee sales back to Kenya. In the early 1950s, shortly after the Mau Mau uprising in Kenya, the government passed a farm bill that allowed every family to increase farmland ownership and grow crops to increase income in addition to self-sufficiency. This is also the beginning of the transfer of coffee production from Britain to Kenya. Total income rose from £5.2 million in 1955 to £1400 in 1964; 55 per cent of that growth was due to coffee production.

Kenya is a well-known producer based on the size of coffee beans. Usually divided into nine grades, according to the bean type, there are PB, that is, round beans, accounting for about 10% of the total output, in addition to E (elephant beans), AA, AB, C, T, TT, MH, ML according to size.

AA Plus (AA+): AA grade with excellent cup quality (flavor, taste)

AA: particle size (Screen Size) 17 Murray 18 size

AB: particle size (Screen Size) 15 Murray 16, accounting for the majority of production

C: those whose particle size (Screen Size) is smaller than AB

TT: lighter beans blown by an airflow filter from AA and AB beans

T: from C-grade beans, lighter beans blown by an airflow filter

E:Elephant Bean is a large mutant bean, also known as Elephant ear.

UG: those who do not meet the above criteria

PB: round bean Peaberry, classified by appearance, independent of flavor weight

Knowledge giveaway: there are two main trading modes of coffee in Kenya: at the Nairobi Coffee Exchange (central auction system), 85% of coffee beans are traded through the auction system. Or through direct trade (often referred to as the "second window"), only 15% of coffee beans are traded through direct trade.
