The grade of raw coffee beans is a standard set in order to understand the quality of raw beans and set a reasonable price in the coffee market. It is distinguished by the size of raw beans, the number of defective beans, the altitude of the cultivated area, the name of the area, etc., and the standards used in different countries and regions are also different.

First, take the appearance and particle size of coffee beans as the evaluation basis:

Country: Kenya, Colombia … Wait.

Evaluation method: the screen is screened on the basis of a screen with a scale of 64 inches. The size of the screen is usually 14 to 20, that is, a screen with a size of 64 inches and a range of 64 inches from 14 to 20 inches.

Second, take the coffee planting at high altitude and the way of treatment as the evaluation basis:

Countries: Costa Rica, Nicaragua … Wait.

Evaluation method: according to the altitude of coffee trees planted, beans with low altitude were selected.

Third, take the proportion of defective beans as the evaluation basis:

Countries: the United States, Brazil, Indonesia. Wait.

Evaluation method: taking 300 grams as the sampling unit, the different grades of defective beans were calculated according to the deduction basis of defective beans.

Governments of coffee-exporting countries usually set up administrative departments or agencies to regulate and monitor coffee trade, and coffee grades are rated by quality inspectors. In many countries, this administrative unit is the Coffee Administration, while in other countries, it is an institution that may belong to the Ministry of Agriculture or the Ministry of Trade and Industry.

It is a pity that there is no international standard for the quality of graded coffee Grading Coffee coffee. It is only graded by several coffee characteristics unique to each country of origin. Sample coffee beans are taken from a bag and evaluated according to the standards of that country, and then the whole bag of coffee beans is marked with a grade label, good or bad, depending on the results of the evaluation. Most of the ratings are based on appearance (size, uniformity, color); the number of defective products in each sample, cup quality (cup quality), which of course includes taste and shape, and whether coffee beans are well and evenly roasted.

Because the types and terms of grades vary from country to country, and the quality standards are only suitable for locally produced coffee, if you are not familiar with the grading system of the place of origin, it is not easy to explain the true quality of coffee. At least one thing these countries have in common is that all countries use standard screens to determine the size of coffee beans so that buyers do not have to guess the size of coffee beans provided by producers.

Coffee may have exotic regional names, or may be classified by process (washing or non-washing). It may have a descriptive name, or just one or two letters arranged in number. In specific countries where the coffee industry is nationalised, the grading system seems rather boring. For example, in Kenya, a bag of coffee beans may be washed "AA", plus a number represents one of the 10 brewing qualities, but this ordinary-sounding coffee has always been considered by most experts to be one of the best in the world.
