Episode 652: Kenya Kiriga Estate AA In My Mug Audio

The first coffee bush at Kiriga Estate was planted in approximately 1954 by colonial settlers. At about the same time, less than ten kilometres away along the same Kigio road, a young boy (Aloysius Gakunga, son of the chief for the larger Murang'a county) helped his father – Senior Chief Ndungíu Kagori – plant the first coffee seedling in the area. The area was known as Gaitegi village, Muranga Location 1 (Loco One). A love affair with coffee had been born!
Several years went by and the young boy grew up. He was riding his bicycle along Kigio road and, as he rode past the vast – by now well-established – coffee estates, he promised himself that he would one day own one of them.
He realized this dream in 1976.
The boy, or Mr A. N. Gakunga, sadly passed away in July 2014. By the time of his death, Mr Gakunga had passed his love of coffee and the mantle of Kiriga coffee estate on to Dr Brian Ndungíu Gakunga. Brian was his second child, and the eldest son out of his six children. According to Kikuyu cultural naming systems, Brian is named after Mr Gakunga's father, who was both his grandfather and his pioneer coffee farmer.
Dr Brian Gakunga is a coffee farmer who is well known in Kenyan coffee circles. He is a founding member and a former long-serving Honorary Secretary of the Kenya Coffee Producers Association, which is a national farmers' organisation that works to promote the economic and social interests of the coffee farmers through active participation in the national and international arena.
Brian is also a former Board Member and Chairman of Transitional Exchange Committee (operationally, he was the then-Chairman of Nairobi Coffee Exchange), where over 90% of all of Kenya's coffee is currently sold. He's also currently the Founding Chairman of Africa Coffee Farmers' Network.
Africa Coffee Farmers' Network represents the interests of coffee farmers, as spelt out in the organisation's core objective of improving the earnings of poor coffee farmers in order to break the vicious cycle of poverty. One way of doing this is by getting direct sales for the farmers.
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.
Administratively, Kiriga coffee estate is in the Gatanga constituency of Muranga county, and it's separated from Kiambu county by the Chania river.
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.
Like any natural product, each coffee bean is different - some bigger, some smaller, some longer, some rounder...that's lead coffee buyers many years ago to begin separating the coffee by the size of the bean.
Throughout the world, this is done by screens - like a stack of flat colanders, with each layer having slightly smaller holes in it than the layer above. Whatever the smallest size a bean passes through, that’s it’s size. In most places, they’re named by 1/64th inch - so a screen 18+ means all the beans are 18/64th of an inch or bigger. Simple, right?
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”. There’s one more class you might have tried - “PB” or Peaberry. That’s a bit different again, but it’s usually separated from the other beans because the round cross-section of a peaberry lets it pass through
