Coffee beans are washed and dried, flat beans and round beans

Small and round dark brown coffee beans, quietly emitting a fragrant fragrance in the grinder, injected into the cup showing the beautiful color of amber, these are the three very deep impressions of coffee.

As you explore the history and beauty of coffee, you can also see the coffee trees that are caressed by the tropical sun and whose leaves twinkle. It has a small white flower similar to jasmine, its fruit from green to yellow-green, and finally to red, coffee beans are the seeds in its fruit.

Moreover, if you go to the coffee bean refinery, you will surely see the red pulp called coffee cherry and the fresh and green coffee raw beans with the endocarp and silver skin removed. These are the coffee beans for export.

At present, there are about 60 coffee-producing countries, most of which are located in areas with an elevation of 300 to 400 meters, and sometimes coffee trees are cultivated on highlands with elevations of 2000 to 2500 meters, but those planted on slopes above 1500 meters above sea level are said to be of better quality.

The most suitable conditions for the cultivation of coffee trees are areas with an average annual rainfall of 1500-2000 mm and an average temperature of about 20 degrees.

Coffee is an evergreen plant of the Akanaceae family. If it is wild, it can even grow to more than eight meters. However, in the farm, the height is cut to about two meters to ensure the quality of coffee beans and facilitate management.

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!
