At present, the most important coffee beans mainly come from two varieties, namely coffee arabica and coffee canephore. The former is the so-called arabica coffee bean. The latter is also known as "robusta" coffee beans. The two coffee beans differ in plant, cultivation, environmental conditions, shape, chemical composition, and even processing of subsequent green beans. Generally speaking, the better quality and more expensive coffee beans come from arabica beans.

Coffea arabica

The coffee tree itself is very sensitive to heat and humidity, so its growth conditions-at least 900 meters above sea level highland climate, the higher the height, the better the quality of roasted coffee beans. This variety has a low caffeine content (1.1-1.7%). Coffee beans are green to pale green in color, oval in shape, and curved in grooves.

Coffearobusta

It accounts for about 20%-30% of world production. Have extremely strong resistance to intertropical climate, cultivate easily. It grows especially well at sea level heights of 200 - 300 meters. However, its unique resistance also makes its concentration higher and its taste more bitter. The caffeine content is high (2 - 4%). Coffee beans are round in shape, brown in color and straight in grooves.
