Most grades are based on the appearance (size, uniformity, color) of coffee beans; the number of defective products in each sample; cup quality (cup quality), which also includes taste and shape, and whether coffee beans are well roasted. The types and terminology of coffee caf é s vary from country to country, and the quality criteria are only suitable for locally grown coffee, so it is not easy to really explain the quality of coffee beans without understanding the grading system of the origin.

Coffee may have exotic regional names or may be classified by process (such as washing or drying). For example, in Kenya, a bag of coffee beans may be washed "AA", plus a number representing 10 brewing quality grades.

Most Caribbean and Central American countries use grades that represent high levels: for example, the coffee trees in El Salvador are Arabica, mainly Bourbon and Pacas. The coffee is refreshing and uniform, which is divided into three grades according to altitude, namely SHG (Strictly High Grown), SG (High Grown) and SC (Central Standard). Coffee beans in Mexico are washed and divided into three grades according to their height.
