Qianjie-introduction to coffee grading in Kenya

Kenya

Kenya is an important force in East Africa in the coffee world, and it is a leader in both its coffee quality and its business strategy.

The excellent coffee produced here has a clear, bright and rising flavor throughout the front and back of the tongue. The flavor is complex and rich, with very interesting fruit flavors (berries, citrus) and even spicy flavors. Clean, bright, rare wine (grapefruit) quality.

Usually excellent Kenyan coffee is not sold as a simple AA or AB, it will participate in various coffee auctions in Kenya, and only the highest bidder can win the bid. The producing areas attach great importance to variety research, planting improvement, improving farmers' cultivation skills and so on.

The method of grading beans varies slightly from place to place. While KENYA uses sieve size as the standard and combines density and shape to classify coffee, what are the grades of KENYA?

KENYA coffee is graded as E-PB-AA-AB-C-TT-T-MH/ML.

KENYA E

The screen size is more than 18, which is called "Elephant Bean". Two face-to-face two seeds merged into one, suddenly mutated beans.

KENYA PB

It is also included in Kenya E, commonly known as peaberry.

KENYA AA

The sieve size is 17: 18, 1400 and 2000m, which is the largest size of normal raw beans.

KENYA AB

The screen size is a mixture of grade A (screen size 1617) and grade B (screen size 1516).

KENYA C

The size of the screen is 1415, which is lower than the density of grade AB.

KENYA TT

The size of the sieve is 1517, and the size of beans is similar to that of AA~AB, but the density is low.

KENYA T

Broken, defective or small beans with a sieve size of less than 12.

KENYA MH/ML

Beans that fall by themselves due to overripe before harvest. Among them, the heavy ones are MH grades (MassHeavy) and the light ones are ML grades (Mass Light).

Knowledge: after the coffee is harvested, it must be uniformly purchased, tested and graded by the "Kenya Coffee Bureau (CBK)" set up by the government. The coffee grade is classified by "particle size" and graded according to size, shape and weight.
