From a botanical point of view, the definition of an heirloom variety establishes that this must be open-pollinated. Arabica coffee is a self-pollinated crop, so from the very beginning the definition of heirloom doesn’t apply to Arabica coffee.

For many years in the coffee industry, the word Heirloom has been used as a generic term to describe one or a group of unknown cultivated varieties in a particular lot, farm or region, that over a long period of time has been planted and passed from a coffee farmer to the next.

​Since the Specialty Coffee movement started to rise in western countries, there was an obvious necessity for traceability and more information. Although the Jimma Agricultural Research Center (JARC), has been working since the 70’s in researching and developing new varieties, at the time, importers had very little information to describe the varieties of the coffees they were buying from Ethiopia.

Today, thanks to scientists such as Getu Bekele, who have been studying Ethiopian wild and cultivated varieties for decades, we can learn, recognize and differentiate, two big groups of Ethiopian Coffee Varieties: the Regional Landraces and the JARC improved.

​There are between 6.000 to 10.000 Regional Landraces and the JARC has developed around 40 improved varieties, which has been distributed among farmers all over the country. These improved varieties address issues of CBD, leaf rust, cup quality and yielding, and today, are widely used all over the coffee growing regions in Ethiopia.

For example, if we analyzed the Jimma Region, we can learn that the improved varieties of the area belong to the Metu Bishari Selection of 1974/75 including: 74110, 74112, 74140, 74148 & 74165 varieties. The Regional Landraces found in this area will include: Kuburi, Bedessa, Yawan and Dalacha among others.

Also, there will be a specific and different set of improved varieties and Regional Landraces found in Yirgachefe/Sidamo, Harar, Gera and Walaga.

​On our last trip to Kenya we met the great "Dr. James", who works at the "Kenya Coffee Research Institute" station in Nyeri. In this place, he explained, how they are performing grafting of Ruiru 11 with SL 28, and the importance of its result for the future of the industry.

Grafting in Agriculture, is a technique where tissues of different plants are joined to continue their growth together. This technique seeks to obtain the best of each of the varieties. Generally in plant breeding, the greater the genetic distance between the two parents, the more "vigorous" the child will be (World Coffee Research).

​Ruiru 11 is a variety of high productivity and resistance to diseases. But the problem is that its root is too short, and it is not able to get enough nutrients from the rich African soil. This usually causes poor results in the cup, without the usual complexity of other varieties grown in Kenya.

In contrast, SL 28, is a variety, which as we all know, has an excellent cup quality, but it has low productivity and is susceptible to diseases such as Leaf Rust or CBD.

Dr. James and his team are grafting leaves of Ruiru11 (scion) with a root of SL 28 (stock), to create resistant varieties of high productivity, with the capacity to absorb more nutrients and hopefully, obtain a better quality in the cup .

​It is urgent that we begin to work together towards the development of new varieties and the increment the genetic diversity of this specie that we like so much.

Enjoy the genetic and organoleptic diversity of your Kenyan coffee!

​These initiatives were called "The Green Revolution" and involved the use of high yielding varieties, higher fertilizers dosages, intensive and mono cropping, the development of highly toxic and life damaging pesticides, among others.

After this changes, the food production increased dramatically in the world, and it is said the over 1 billion people were saved from starvation. Today, this very achievement, though remarkable, has costed us dearly in socioeconomic terms for small farmers, reduction of biodiversity, increase of green house emissions and health issues related to the excessive use of pesticides.

​According to the World Coffee Research "most African coffee-producing countries produce substantially lower volumes of coffee than elsewhere. This has profound impacts for farmer livelihoods when farmers are paid per pound of cherry. There is a widespread need for replanting with young trees that are resistant to major diseases and pests (including coffee berry disease, coffee leaf rust, antestia bug and stem borer), and with improved varieties. The World Coffee Research believes that over 50% of coffee trees in Africa are more than 50 years old."

​In Kenya particularly, we have always selected lots where the cultivars are exclusively SL28 and SL34, because we love the complexity, dense sweetness, citric acidity and the viscosity in the cup of these two varieties. But we understand the unpostponable necessity of experimenting and promoting new varieties with higher yieldings, tolerant to diseases and adaptability to warmer climates.

Our new lot Kabunyeria AB is the first ever lot we source of Ruiru11 and Batian in Kenya. Cultivated in the Kericho county at an average altitude of well over 2000 masl, this lot is cupping great for espresso, very sweet with a full body and a gentle well balanced citric acidity.

We invite you to try it and discover the full potential of Kenyan coffees and its new varieties of the 21st century. 

Enjoy your Kenya Kabunyeria AB!

​Kenya is divided into 47 counties, and in only 18 coffee is produced.

Nyeri and Kirinyaga are definitely the most popular counties for traders and roasters in origin. As a consequence of the above, they are also the ones that obtain the highest prices in the auctions of the Nairobi Coffee Exchange.

​So the million dollar question is: why Kiambu does not have the same relevance as its neighbors in the specialty coffee market?

And the answer is not as obvious as you might think.

​If we analyze the type of cultivars used in the three counties, we find that the most common cultivated varietes (between 90 and 95%) are SL28 and SL34, which are as we have said, the ones that produce the best quality in the cup.

Let's look at the altitude, the average range of altitude in the cultivated areas is higher in Kiambu with 1860masl, followed by Nyeri with 1760m and Kirinyaga with 1605m.

Rain patterns. In the three counties are also similar, there are bimodal rain patterns which brings two wet seasons a year (therefore 2 flowerings and two harvests a year), with annual rainfall averages of 953 mm for Nyeri, 1098 mm for Kiambu and 1518 mm for Kirinyaga .

The composition of the soils is similar in all three counties. They are all red volcanic soils, rich in nutrients and organic matter.

And the processing method, exactly the same, fully washed process with double fermentation and sundried on African beds.

​The only fundamental difference lies in the annual production of smallholders (who are the ones that produce the microlots we are all seeking for) and their respective cooperatives. Nyeri being the first of the country with 6630 Tons., which represents 21% of the total production, second is Kirinyaga with 5870 Tons., representing an 18.5% and sixth is Kiambu with 2560 Tons., representing a 8% of the total country. (Statistics provided by the Kenya Coffee Board for 2012)

From the above we can conclude that the success of the "trademark" Nyeri and Kirinyaga in detriment of Kiambu, is due exclusively to a matter of quantity and therefore overexposure in international markets, and not to the potential to produce quality. From a macro perspective, the various factors influencing high quality production are virtually identical in all three counties.

To finish, just say that it is undeniable that in Nyeri and Kirinyaga there are exceptional lots, but they are also in Kiambu; It's just a matter of seek, discover and blind cupping!

Enjoy your coffee ... from Kiambu
