Indonesian coffee beans

Coffee beans are handled in different ways in different countries, so there are a variety of classification methods, and there is no unified method in the world at present. Generally speaking, a producing country uses only one method, which is commonly used in the following ways:

◎ grades according to the size of coffee beans

This classification method is based on a variety of perforated screen classification, the screen has a variety of specifications, identified by the number, the number is associated with the mesh. The size of the mesh-1 stroke 64 inches is the unit of calculation. If the diameter of the mesh is 18 stroke 64 inches, the number of the screen is 18; if the diameter of the mesh is 17 inch 64 inches, the number of the screen is 17. And so on, there are 19, 16, 15, 14 and other numbered screens.

The process of screening is to put the coffee beans on the Internet and shake them back and forth by machine or manually, and the beans smaller than the mesh will fall and be removed, and the beans that have been rejected will be screened through a smaller screen. After layers of screening, the grades of coffee beans are compiled.

After classification, it is divided into AA, A, B, C and PB series. AA is the highest, A, B and C decrease in turn, and those below C are usually used as feed or fertilizer. In addition, round beans have a special flavor, and beans are already relatively small, so they have their own grade, that is, "PB", which is usually more expensive. This classification is generally used in Kenya, New Guinea, Puerto Rico, Zimbabwe, Tanzania and Uganda.

(1) the size of coffee beans

Some people say that the size of beans will not affect the flavor of coffee, such as Yemen Mattari, beans have large and small particles, but it is still the top grade of coffee. However, in many producing areas, the size of coffee beans is indeed a valuable indicator.

This classification is generally used in Kenya, New Guinea, Puerto Rico, Zimbabwe, Tanzania and Uganda. In addition, this classification is also used in many Brazilian coffee.

(2) the number of defective beans

This is the earliest method of grading and is still used in many parts of Brazil. The method of identification is to randomly take 300 grams of samples, find out the defective beans in the samples, and accumulate different scores according to the types of defects. After the identification is completed, it will be rated as Gr2~Gr8 according to the accumulated defect score, but there is no Gr1. If you want to buy first-class Brazilian beans, it will make a joke.
