Kiambui Coffee Factory is located in the Central Province or the Kirinyaga District in Njukiini location of Gichugu Division near Embu town.  The coffee station was established in the 1970s and rests on a 4 acre piece of land, which serves the Kiambui villages.

The coffee station is affiliated to the Kanjuu Farmers Co-operative Ltd and its membership currently stands at 1,000 of which 800 are active farmers and 200 are inactive farmers.  

The Kiambui coffee station is managed by Mathew Nyange, with 6 permanent members of staff and several casual members.  The number of casuals varies from year to year depending on the crop harvest, but during the peak season, the factory employs about 9 casuals and 2 off-peak.  The permanent staff are responsible for weighing coffee, selecting and grading of the coffee, paying farmers and addressing any farmers' complaints.

The station lies at about 1,383m and experiences moderate bimodal rainfall of about 1,200mm p.a. and the temperatures range between 13.26 degrees Celsius.  The long rains fall between March- May, whilst the short rains arrive between October- December.  

The station experience a biennial production cycle, with the early harvest taking place between April- June and the late season between October and December.  The main varieties of coffee grown are SL28, K7 and Ruiru 11, with SL28, K7 accounting for 99% of all coffee produced, whilst Ruiru 11 accounts for 1% of all production.  

The farmers in this area are active in coffee farming because it is the main major cash crop in this area. The management is encouraging the farmers to cultivate more coffee due to the increase in price and have begun to offer crop advances to the farmers to encourage production. 

The station has begun to undertake initiatives to protect the environment, which has included 3 waste water soak pits, that allow for the water to soak back into the soil.  The surrounding environment is mostly made up of indigenous trees, which are well protected by the community.  

The affiliate members of the station carry out all agronomic activities associated with coffee production i.e they source coffee from the Coffee Research Station and plant it according to the stipulated guidelines.  The fieldwork carried out involves weeding, pruning, spraying and application of fertiliser, mulching and technical advice.  The technical advice is offered through farmer training g

Compliance with the agreed guidelines is checked and supervised by the field committee which goes around the farms,  the field committee usually check that the coffee is not intergrown with other crops such as maize and beans, although they do allow intercropping with macadamia.  

After harvesting the coffee is delivered to the factory and undergoes the wet processing method, water is pumped from River Kii to the reservoir tanks for pulping and recirculation.  After pulping the coffee is stored overnight, washed, soaked and spread on the drying on tables.  The parchment is then frequently turned on the drying tables, sorted and then stored whilst it awaits delivery to the millers.  To ensure that the processing is carried out efficiently the station has invested in a pulper, a recirculation system and about 10 conditioning bins.
