The region encompasses Kisii, Nyamira, Migori, Homa Bay, Siaya, and Kisumu counties—each contributing unique terroir characteristics to the region's growing reputation for sweet, creamy coffees with distinctive nut and fruit notes.
Coffee was introduced to parts of Kisii in the early 1930s, making it one of the first areas in Kenya where smallholder farmers were encouraged to plant coffee on their small landholdings. Today, more than 600,000 smallholders farming fewer than five acres compose 99% of the coffee farming population of Kenya, with Nyanza emerging as a critical growth region. The national coffee revival programme aims to boost production from approximately 50,000 metric tonnes to 150,000 metric tonnes by 2029, with Nyanza counties positioned at the heart of this transformation. A regional forum in Kisumu has brought together representatives from Kisumu, Siaya, Homa Bay, Nyamira, Migori and Kisii counties as part of a nationwide government programme seeking to revive coffee as a major cash crop.
