Introduction to the evaluation and grading of coffee beans in Kenya

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

There are many kinds of coffee, and each has its own grade. If you want to have a cup of coffee, there are many different choices. Among them, beans in the same producing area are divided into several grades, and consumers who do not have a clear understanding of this will look a little dizzy, so the editor collected some grading information about Kenyan coffee beans to share with you.

The quality of Kenyan coffee is strictly controlled, and it is divided into AA,AB,C,E,PB,TT,T,ML,MH according to size, particle and shape. These grades mainly distinguish the shape and size of beans, but not absolutely represent the quality of beans. Many people believe that beans with larger grains contain more oil that produces the aroma of coffee, and because of this, beans with larger grains are more expensive in the market.

Take Kenya's AA as an example. In the same grade of beans, the highest grade is manor beans, followed by "". Then there is the general AA,AB grade compared to the smaller beans in the AA,C grade, and the extra-large elephant beans in the E grade. TT, T, ML, and MH are the local non-flowing beans.

PB (Peaberry round beans) is special. Round beans (PB) are usually produced at the end of coffee trees that bloom too late or too early. Because the output is rare, accounting for only 10% of the output, the round beans produced by the same coffee tree are more expensive than other flat beans (Flat Bean). While the round beans are specially collected together, they tend to remove defective beans, reduce the proportion of defects, make the particles more consistent, make the baking more uniform and improve the taste.

As for the distinction of quality, Kenya uses the digital grading method to distinguish the quality of coffee, but this digital grading method is not much publicized, so few people know about it. Therefore, the grading is based on particles, and the PB with different shapes is about the same as AA, but if it is manor or grade, it is two or one grade respectively. For example, AB Manor beans are about the same as AA and PB.
