Guji is a Zone in the Oromia Region of southern Ethiopia. Most residents of this region are Oromo and speak the Oromo language, which is entirely different from the Ethiopia’s main language of Amharic. Like many of the country’s coffee growing regions, the culture of the Guji Zone varies from woreda to woreda and speaks to the diversity of people who cultivate coffee. More small washing stations are being built in Guji to respond to the demand for improvements in processing to fully capture the range of attributes found in Ethiopian coffee. The Zone’s principle fresh water source is the Ganale Dorya river, which also acts as the boundary line with the neighboring Bale zone to the east.
