In Kenya, the quality of coffee has seen a decline over the past few years, with many attributing the blame to an increase in Ruiru 11 and Batian varieties. However, this theory is challenged as many famous estates and associations still produce coffee with these hybrids. The system in Kenya is complex, with a colonial export system centralized through an auction system, limiting traceability and financial transparency. The process involves numerous middlemen and delays in payment to farmers, leading to high financing costs and low profits. Furthermore, the decline in coffee production in Kenya is also attributed to political factors and competition from other cash crops like tea.
