Introduction to the National Standard of Yunnan Coffee Raw Bean-planting Environment Manor area treatment method

Representative countries: Guatemala, Costa Rica, Savaldo and other Central American countries.

The higher the altitude of the origin, the better the quality of coffee. Because of the low altitude and hot climate, coffee trees grow faster and absorb less soil nutrients, so the taste of coffee is poor.

Those growing at 1375m to 1524m are extremely hard beans (SHB); those growing at 915m to 1375m are high hard beans (GHB); those growing at 610m to 915m are called hard beans (HB); those growing at 300m to 1000m are called Pacific grade (Pacific) Hawaiian Kona coffee beans are divided into two categories: Type1 and Type2, Type1 is flat beans, Type2 is round beans. Under the two levels, it is divided into several levels according to the size and the number of defective beans.

Colombian coffee is divided into Supremo, Excelso, Extra and other three levels, Supremo is the highest level, Excelso is the mixed representative of Supremo and Extra: Brazil, Indonesia, Ethiopia, Cuba, Peru and so on.

The method is to randomly take 300g samples and put them on black paper, and different defects correspond to different points, such as 1 point for 1 pebble, 5 points for 1 big pebble, 1 point for 5 broken beans and 1 point for 5 pest beans. Finally, it is graded according to the accumulated defect score, the highest level is NY2 and the lowest level is NY8. Indonesian coffee beans are divided into 6 grades, Gr1~Gr6, and Ethiopia coffee beans have the highest level of Gr2.

Most of the people who use this classification are South American countries. I don't know what Ethiopia and Indonesia do to represent the countries: Kenya, Papua New Guinea, Zimbabwe, Tanzania, Uganda and so on.

Coffee beans from the same origin must be large and full, which means that the coffee fruit is picked only when it grows to its best condition, and the beans in the coffee fruit can reflect the best flavor.

This grading is achieved through a sieve, where the coffee beans are placed on the sieve. After shaking back and forth, the beans smaller than the mesh are screened out, and the beans are screened again with a smaller sieve, so that after layers of selection, the coffee beans can be graded. The mesh size is calculated in 1 stroke 64 inches, the number is 19 if the diameter is 19ax 64 inches, and the number is 16 if the mesh is 16 picks 64 inches. Pingdou 20-19 is extra-large, 18 is large, 17 is quasi-large, 16 is ordinary, 15 is medium, 14 is small, and 13-12 is super-small.

According to the size, the coffee beans are finally divided into AA, A, B, C and PH levels, and AA is the highest level. coffee beans of this level are eligible for selection of selected coffee, and coffee below C grade is usually used as feed or fertilizer.
