Background

Coffee beans are plant fruits used to make coffee. Broadly speaking, there are 2 kinds of coffee beans in the world, arabica beans and robusta beans. The coffee fruit consists of two oval seeds facing each other. The surfaces that abut each other are flat junctions, called flat beans. However, there are also beans which consist of one round seed, called a bean, and which do not have a different taste. The earliest manner in which arabian people consumed Coffee was to chew whole fruits (Coffee Cherry) to extract their juice. They then mixed the ground coffee beans with animal fat to serve as a physical supplement for long trips, and until about 1,000 b.c. the green coffee beans were taken to boil in boiling water to an aromatic beverage. After three centuries, Arabic began to roast and grind coffee beans, and the drinking of wine was strictly prohibited in the Koran, so that Arabic consumed a lot of coffee, and religious religion was also a great factor that prompted the wide popularity of coffee in the Arabic world.
