The melting point of caffeine is as high as 237 degrees Celsius, so the roasted caffeine is almost completely retained and dissolved in the cup. People often mistakenly think that the caffeine of deep-baked beans is lower than that of shallow-baked beans, but it may be just right.

Ethiopian "beans can not be seen" coffee varieties
In recent years, scientists have studied the coffee gene in Ethiopia and believe that Arabica originated from the Cafa forest in the southwest-the Gemma producing area-and then transplanted to Harald in the east and Lekamp in the northwest. The latter two genes are far less complex than coffee in the Kafa forest. Although the coffee beans in the northwest are obviously more spectacular than those in the southwest, the cup test results are not as good as those in the southwest.

The main producing areas and characteristics of Coffee in the World
Coffee production zones (commonly known as coffee belts) range from 25 degrees north latitude to 30 degrees south latitude, covering many countries in Central, West Africa, the Middle East and South Asia, the Pacific, Latin America and the Caribbean. The reason why coffee cultivation is concentrated in this area is mainly due to the limitation of temperature. Because coffee trees are vulnerable to frost, neither north nor south latitude is suitable, especially in the tropics.
