What are coffee beans and how are they produced?
Coffee beans are the seeds of the coffee plant, typically found within the red or purple fruits known as coffee cherries. The two most common species cultivated for commercial coffee production are Coffea arabica (Arabica coffee) and Coffea canephora (Robusta coffee). The production process begins with the flowering of the coffee plant, followed by the development of the cherries over several months. These cherries are harvested when ripe, either by hand or mechanically, depending on the region and farming practices.
Once harvested, the beans must be extracted from the cherries. This is done through various methods, such as the dry process, where cherries are sun-dried and then hulled, or the wet process, which involves removing the flesh of the cherries using water. After extraction, the beans are fermented, washed, and then dried before being sorted and graded based on size and quality. Finally, they are roasted, which enhances their flavor profile.
Where are the primary coffee-growing regions located?
The primary coffee-growing regions, often referred to as the “coffee belt,” are located between the Tropics of Cancer and Capricorn. This belt encircles the globe and includes numerous countries across Central and South America, Africa, and Asia. Countries like Brazil, Colombia, and Ethiopia are among the largest producers, each contributing distinct flavor profiles influenced by their unique climate, altitude, and soil conditions.
