Last Updated: 2024/11/03, There are two ways to grade coffee beans, one is to filter the number of points, one is to elevation points. The size of the round beans is generally smaller than the flat beans, the round beans are between 8-13, and the flat beans are between 12-29. 8,9,10... 12,13... 18... 29= ,,......, Extra large. The bigger the number, the bigger the bean. SC-19, for example, is bean number 19.

There are two ways to classify raw coffee beans, one is the filter number, and the other is the elevation.

It is divided by filter number, and the size is based on screen size (size).

Round beans are generally smaller than flat beans, between 8-13 and 12-29.

8, 9, 10. 12, 13. 18. 29 = >, extra-large. The bigger the size, the bigger the beans. SC-19, for example, is the No. 19 bean.

Grade by level

According to the elevation of the cultivated land, it can be divided into seven grades. Generally speaking, the quality of highland beans is better than that of lowland beans, and the price is higher because of the increase in freight.

Sequence number equal order abbreviated elevation

1 selected quality beans S.H.B 4500 ~

2 good coffee beans H.B 4000mm 4500

3 medium coffee beans S.H 3500 million 4000

4 Super high-grade washed coffee beans E.P.W3000~3500

5 first-class washed coffee beans P.W 250000 3000

6 special water washed coffee beans E.G.W 2000 2500

7 High quality washed coffee beans G.W~2000

Grading purpose: to make the size of raw beans uniform, which is conducive to the baking operation, and improve the value of raw beans.

Screen diameter

The size of the international practice is 9: 22, and the number used represents the diameter of the screen, with this number as the numerator and 64 as the denominator, in inches. For example, 14 refers to raw coffee beans that can be sifted through a 14-inch screen with a diameter of 64 inches, and 19 + refers to raw coffee beans that can be sifted with a diameter of more than 64 inches with a 19-inch screen.

Grading standard and code name

The governments of each coffee-exporting country set their own grading standards and code names.
