About

A distinctive Kenyan washing station technique where fermented beans are soaked in clean cold water, then flushed with warm water, and soaked again — sometimes cycling through multiple temperature changes over 24-48 hours. This thermal cycling is believed to further clean the bean surface, lock in acidity, and contribute to the signature bright, juicy profile of Kenyan AA coffees. The technique is labor- and water-intensive but produces remarkably clean cups with intense citric acidity. Also practiced in some Rwandan and Burundian washing stations.
