Introduction to the origin, characteristics, flavor and taste of coffee beans

At present, the main tree species planted are Arabica species, Robusta species (Carneva species) and Liberika species. It can be subdivided into dozens of varieties, which will be distinguished in production, circulation and trading.

Even in the same producing country, it will have a subtle influence on the flavor and quality of coffee beans and produce their own characteristics because of the differences in climate, altitude and soil quality in different regions. Therefore, according to the variety, origin, brand, there will be different attributes; therefore, it is impossible to describe the characteristics of a country's coffee beans in one sentence!

1 special grade beans 1.500 ~, 2 high grade beans 1.200 × 1.500, 3 medium beans 1.000 × 1.200, 4 grade water washed beans 900 × 1.000, 5 grade water washed beans 760 × 900, 6 special grade water washed beans 610 × 760, 7 excellent water washed beans ~ 610

e. Quality

According to the statistical method, the type and quantity of dopants contained in a certain amount of samples are converted into percentage "defect number", and the basis for determining the quality class is that the smaller the defect number is, the higher the quality is.

f. Taste

Brazil, Haiti, Kenya, say and other countries all have their own taste testing methods, which can be exported only after taste testing.
