Kiriga Estate sits between 1,550 and 1,650 metres above sea level. It is approximately five kilometres from Thika town, which is an industrial town in the central province of Kenya. It's four kilometres from Blue Posts hotel, which has the famous Chania and Thika falls. Thika lies 50 kilometres northeast of Nairobi.
Kiriga coffee is predominantly SL28 variety (notable for its world-renowned cup quality). The farm has an estimated two hectares of Ruiru 11 variety (which has improved resistance to coffee berry disease and leaf rust); some K7 variety (similar characteristics as SL28, but with better resistance to leaf rust compared to SL28); and a field of the newest Batian variety. About 60% of the coffee that the estate produces is AA/AB.
Well...in Kenya they use the same screens, but give them different names. An “AA” is screen 17 and 18, an “AB” is screen 16 and 15 and anything smaller (but still a whole bean) is a “C”.
