The sort of coffee-tree Coffea arabica came from Ethiopia (Abyssinia), namely from the south-west part of Ethiopian Highlands, which is called Kafa. People used leaves and fruit of coffee-tree since ancient times, long before the Semite tribe on the Arabian Peninsula had known about this plant.

The discoverers of coffee weren’t the Arabs, but Ethiopians – the group of some nationalities (Amhara, Tigray-Tigrinya, Gurage…). The group has appeared in the first thousand B.C., when inhabitants from the Arabian Peninsula moved to present Ethiopia and mixed with Negroids – Cushitic and Nilotes.

Ethiopians pounded coffee-tree fruits, mix them with adipose and made from them dumplings as large as plums. Fats, which were mixed with nourishing coffee fruits and seeds protein, empowered people. Coffee was a marvelous pepper-upper. From the fruits juice the nomads made beverage, looked like wine, and from the leaves – drink, like tea.

With time people started to make hot beverage from the seeds of the coffee-tree. At the beginning they used it during religious ceremonies. Later it became a national drink of the Ethiopians. Afterwards seeds and leaves harvesting became a separate trade which were spread from Africa to Yemen.
