Coffee is a widely consumed stimulant beverage prepared from roasted seeds, commonly called coffee beans, of the coffee plant. Coffee was first consumed in the 9th century when it was discovered in the highlands of Ethiopia. From there, it spread to Egypt and Yemen, and by the 15th century had reached Persia, Turkey, and northern Africa. From the Muslim world, coffee spread to Italy, then to the rest of Europe and the Americas. Coffee came to Kodagu with the British. They found a place similar to other coffee cultivating areas around the world and convinced the locals to produce. Today, coffee is one of the most popular beverages worldwide. It is also one of the most popular commercial beverages worldwide. Coffee berries, which contain the coffee bean, are produced by several species of the small evergreen bush of the genus Coffea. The two most commonly grown species are Coffea canephora (also known as Coffea robusta) and Coffea arabica. These are cultivated in Latin America, Southeast Asia, and Africa. Once ripe, coffee berries are picked, processed, and dried. The seeds are then roasted, undergoing several physical and chemical changes. They are roasted to various degrees, depending on the desired flavor. They are then ground and brewed to create coffee. Coffee can be prepared and presented by a variety of methods.
