Classification and classification of coffee

In order to distinguish between good quality coffee beans and poor quality coffee beans, we have to grade the coffee. Coffee grading is usually based on defect rate, bean size, altitude, raw bean density, treatment standards and so on, so it is more often described by a variety of standards.

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

It is divided by the number of the filter screen, and the size is in the unit of the screen (size).

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

8, 9, 10. 12, 13. 18. 29 = > small, medium, ordinary. Quasi-big. Big, 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.W 30003500

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 according to defect rate

American standard USP

European standard EP

Euro preparation

The best standard GP

Gourmet preparation

Many countries have USP, EP and GP standards, and USP\ EP is relatively more common. European and American standards are based on the specific requirements for the defects or items of raw beans, and sometimes there are other standards among them, which are not detailed because different national standards are different. Generally speaking, the EP standard is higher than the USP standard.

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.
