The traditional coffee bean classification method is usually based on the classification standard defined by the coffee producing country, and then agreed on the international market, and traded under such tacit understanding.

For a long time, coffee producing countries have their own classification and evaluation standards for coffee, which serve as pricing guidelines for coffee trading markets. However, in recent years, coffee consuming countries have begun to demand uniform evaluation standards, which is the rise of the so-called specialty coffee concept.

In the past, there were roughly three classification and evaluation criteria for coffee producing countries:

1. Graded according to altitude of origin

2. the size of that coffee bean sieve, i. e. the coffee bean size

3. According to the sieve, the proportion of defective beans and the taste test comprehensive method
