tribe located in northwest Tanzania in modern-day Kagera region was the only recorded tribe that used the beans. The tribe boiled the Robusta beans and steamed them with various herbs and chewed
on the mixture as a stimulant. The tribe also used the coffee beans as a form of currency and the growing and cultivating of the beans were highly controlled by tribal leaders. The Tanzanian

output originates from small farmers rather than estates and provides employment to 400,00 families and affect more than 2.4 million citizens directly. There are three ways a farmer can sell
his product. The Internal market where the produce is sold at a price decided by the farmer directly to private coffee buyers, village groups or coffee cooperatives. This practice is the most
common between small farmers due to the low yields per farmer.
