Kenya

Why this origin matters

Kenya grows a small crop, all of it arabica on the governed USDA estimate charted below, and has organised it unlike most origins. Roughly four fifths of the coffee is sold through producer co-operatives, on the USDA attaché's account, and over 95 per cent of sales pass through one auction in Nairobi that has run since 1935. The country also bred its own plants twice over: single-tree selections made at a government laboratory in the 1930s, which are still grown, and two disease-resistant varieties released in 1985 and 2010 after an epidemic of a fungal disease first reported in Kenya led, on the catalogue's account, to the loss of half the country's production. What the documents CoffeeHQ read describe in 2026 is a sector in the middle of being rearranged, with a new coffee law, a new regulator, a new payment system and a planting drive that the research institute cannot supply with seedlings fast enough.

Where coffee grows

The USDA attaché's 2026 report does not list Kenya's growing counties; its map, credited to the Coffee Board of Kenya, is an image CoffeeHQ could not read. What it says in words is that the Mount Kenya region is a key one, that a government planting programme spans the Central, Eastern and Rift Valley regions, and that coffee has been uprooted for housing around Nairobi, Thika, Kiambu and Nyeri. It puts the planted area at 106,000 hectares in 2025/26 and the trees at 172 million. A 2021 study of co-operative wet mills in Embu County, on the eastern slopes of Mount Kenya, gives coffee as grown in 32 of Kenya's 47 counties, and describes the part of Embu that suits coffee as lying between 1,520 and 1,820 metres with two rainy seasons, one from March to July and one from September to mid-December. That altitude is one county's, from one study, and is not a figure for Kenya.

Coffee land that became housing, and a planting drive short of seedlings

Two movements in opposite directions run through the attaché's 2026 report. Over most of the previous decade, it says, coffee farms on the edges of Kenya's towns were systematically uprooted for housing, and it names Nairobi, Thika, Kiambu and Nyeri as where this was most common. In the two years before the report the trend slowed, which it attributes to a stagnant property market; it notes that no clear land-use policy safeguards arable land. Industry analysts quoted in the report regard that as a temporary reprieve that could end if coffee prices slump.

At the same time the government is, in the report's words, aggressively pursuing an expansion programme in the Central, Eastern and Rift Valley regions. It works through the New Kenya Planters Co-operative Union, which uses a government-supported revolving fund to give farmers saplings and fertiliser, and several county governments add grants of their own. The limit has been planting material. The Coffee Research Institute, the report says, faces a massive backlog and is overwhelmed by the demand for seedlings despite efforts to raise output.

Species and varieties

Kenya's crop is arabica: the USDA's table has no robusta in any season it covers. A 2022 study by Kenyan and Chinese researchers says production comes mainly from four locally developed cultivars, Ruiru 11, K7, SL28 and SL34. Batian, released in 2010, is the fifth name in the documents read. The World Coffee Research catalogue credits SL28 and SL34 to Scott Agricultural Laboratories and Ruiru 11 and Batian to the Coffee Research Foundation, now part of the national agricultural research organisation. No source read gives the share of land under any of them.

Two selections from the 1930s, and a label that may be wrong

SL stands for Scott Laboratories. The catalogue's history says the colonial government set up Scott Agricultural Laboratories in 1922, moved its coffee section there in 1934, and that single-tree selections made between 1935 and 1939 were given the prefix. Forty-two trees of various origins were selected and studied for yield, quality and resistance to drought and disease.

SL28 was selected in 1935 from one tree in a population called Tanganyika Drought Resistant, grown from seed a senior coffee officer had collected on a tour of what is now Tanzania in 1931. SL34 was selected in the late 1930s from a single tree on the Loresho Estate at Kabete that was labelled French Mission, the name given to coffee descended from the missionaries' Bourbon seed. Genetic tests, the catalogue says, have confirmed that SL28 is related to the Bourbon group and have indicated that SL34 is related to Typica, which a French Mission label would not lead one to expect. The catalogue goes no further than saying it is possible that the story of SL34 coming from a French Mission population could be incorrect.

A third name from the same decade, K7, was released in 1936 after five generations of selection; the catalogue credits it to an individual farmer's selection. The catalogue says there are SL28 trees in many parts of Kenya that are 60 to 80 years old and still productive.

A disease first reported in Kenya, and the two varieties bred against it

Coffee berry disease is caused by a fungus, Colletotrichum kahawae, that attacks green berries. A 2017 paper whose authors include a scientist at Kenya's Coffee Research Institute says it was first reported in Kenya in 1922, is still restricted to Africa, and may cause losses of up to 50 to 80 per cent of a crop in years of severe epidemic where nothing is done to control it. The SL selections are susceptible to it.

The catalogue's history of Ruiru 11 starts from an epidemic in 1968 that, it says, led to the loss of half of Kenya's production. In the 1970s the coffee research station at Ruiru began breeding for resistance, and Ruiru 11 was released in 1985: a compact plant made by crossing a tall, many-parented male line, which carries resistance from sources including Rume Sudan and the Timor Hybrid, with a Catimor mother. Batian, a tall variety drawn from the same breeding lines, followed in 2010. A 2026 paper on the genetics of resistance says that resistance to the fungus can be durable during epidemics, and gives Ruiru 11 and Batian as the documented cases.

Ruiru 11 has a cost that the catalogue states plainly. Its seed is made by pollinating the mother plants by hand, and that has made it difficult to produce enough to meet farmers' demand. The 2022 study of Kenyan varieties adds a second caution, about the cup: it calls Ruiru 11 controversially considered a low cup quality cultivar, reports a strong market preference for SL28 for its perceived quality, and says that comprehensive sensory studies comparing the varieties are still lacking.

Harvest

The attaché's report names no harvest months, and CoffeeHQ has found no document that does and that it could open. What the report describes is the trading year that follows from the harvest. Kenya's marketing year runs from October to September. Exports typically start low in October, reach their lowest by December and climb to a peak between April and July. The table below marks those months and no harvest. The older entry on this page described a main crop and a smaller second one; that is widely said and is not repeated here, because nothing read supports its timing.

How the coffee is processed

The wet method is the one predominantly practised in Kenya, according to the 2022 study, which processed its own samples by what it calls the standard sequence of pulping, fermentation, washing, sun drying and sorting. In the co-operative sector the work is done at wet mills, known in Kenya as factories: the 2021 Embu study counts 56 small-scale wet mills in that one county, belonging to 24 co-operative societies with more than 79,000 members. CoffeeHQ has read no technical description of how Kenyan factories ferment, soak or dry coffee, and so does not describe a distinct Kenyan process.

How it is graded and sold

Kenya sells green coffee. Green beans were 800,000 of the 840,000 bags exported in 2025/26 on the attaché's estimate, and the report notes that the country has yet to build large soluble plants. The European Union has historically taken more than half. On the trade figures the attaché reprints, charted below, the United States was the largest single destination in 2024/25 with 17.2 per cent, ahead of Belgium and Germany; Belgium's volume more than doubled between 2022/23 and 2024/25 while Germany's and Sweden's fell. Prices at the Nairobi exchange, which are bid in US dollars per 50-kilogram bag, averaged 375.24 dollars in October 2025 and 268.77 dollars in April 2026. January 2026 was an exception to the usual pattern: exports reached 231,561 bags, which the report calls an all-time high, and puts down to the United States' duty-free access for Kenyan goods being extended retroactively and to a large one-off shipment to Sudan.

An auction since 1935, and who runs it now

The Nairobi Coffee Exchange is, in the attaché's description, a spot market founded in 1935 that facilitates over 95 per cent of Kenya's coffee sales. The rest is sold by direct contract between producers' agents and exporters, and those sales have to be registered with the regulator. The exchange itself is overseen by the Capital Markets Authority, the financial regulator, which licenses the brokers who prepare the auction catalogues. As of early 2026 it had licensed sixteen. Eleven of them are farmer-owned co-operatives or unions and the rest are private, and fifteen were trading in the 2025/26 season.

That arrangement is recent. The report describes reforms under way since 2022: a reorganised exchange; a Direct Settlement System, a digital platform meant to pay farmers directly and faster; and brokers taking over the classing of coffee, the catalogues and the management of both auction and direct sales. It also records what the change cost. It describes 2023/24 as a season of sector instability, set off by abrupt reforms that overhauled marketing and licensing in mid-season and led marketing agents to suspend the supply of inputs to farmers.

The Coffee Act of 2026

In March 2026, the attaché reports, Kenya enacted a new Coffee Act. It moves regulatory and commercial oversight from the Agriculture and Food Authority to a revived Coffee Board of Kenya, sets up a Coffee Research and Training Institute independent of the national agricultural research organisation, writes the reforms of the exchange and the settlement system into law, and hands the licensing of coffee millers to the county governments. The Act itself, as Kenya's official law reports publish it, is the Coffee Act, No. 8 of 2026, assented to on 13 March 2026 and in force from 27 March. It establishes the Coffee Board of Kenya and a Coffee Research and Training Institute, and moves to them the coffee functions, staff and property of the Agriculture and Food Authority and of the national agricultural research organisation. It provides for coffee exchanges and a direct settlement system through which growers are paid. And it requires a licence from the county government to run a pulping station, a growers' mill, a commercial mill, a roastery or a warehouse. CoffeeHQ read those provisions and not the whole Act.

A second set of rules comes from the buyers' side. To keep access to the European Union, Kenya has launched traceability systems to meet the Union's deforestation regulation, which the report says larger exporters must comply with by 30 December 2026 and smaller ones by 30 June 2027. Those dates are as the report gives them in May 2026; they have been moved before.

Seven letters for size, shape and density

The letters on a Kenyan lot are grades of the green bean, not of its flavour. The 2022 study says commercial green coffee in Kenya is mechanically graded as E, PB, AA, AB, C, TT and T on size, shape and density, with no account taken of the variety. It collected its own AA samples with a 7.2-millimetre grading sieve. CoffeeHQ has not read the Kenyan regulation that defines the grades, and gives no dimensions for the others.

The same study calls AA the country's largest market category and repeats its high reputation. A grade says how large and dense a bean is. It does not say what a lot will taste like, and two lots of the same grade from different factories or varieties need not resemble each other.

Coffees from this origin

How coffee is drunk in Kenya

Kenya drinks little of its own coffee: 62,000 bags in 2025/26 on the USDA attaché's estimate, against production of 850,000. The attaché expects no growth in 2026/27. It gives three reasons: inflation that has cut what households can spend; a spread of coffee houses in Nairobi and other cities that has, in its words, lost its momentum, which it ties to the departure of several large non-governmental organisations and donor operations that had supported the urban middle class and expatriate communities it calls the backbone of the high-end market; and a slowdown in tourism, since hotels and lodges are a main outlet. About a third of what is drunk is soluble coffee. Kenya imports soluble coffee, and the report notes that it has yet to establish large soluble plants of its own.

Consumption figures are the USDA attaché's estimates in green-bean equivalent for the marketing year beginning October 2025. The reasons are the attaché's reading, not a survey.

History

Two accounts of how arabica reached Kenya were read, and they differ by a few years. The World Coffee Research catalogue says French missionaries of the Spiritan order planted Bourbon seed from Réunion at a mission at Bura, in the Taita Hills, in 1893, that seedlings were taken to another mission at Saint Austin near Nairobi in 1899, and that seed was distributed to settlers from there. William Ukers's trade history of 1922 dates the introduction of coffee cultivation into British East Africa, from Réunion, to 1901. Ukers gives estimates of 1,000 acres under coffee in 1911 and 22,200 by 1916, and exports of nearly 11 million pounds in 1917 and 18.7 million in 1918. His account is a settler's-eye view written for the American trade and describes African people in terms CoffeeHQ does not repeat.

Who was allowed to grow it

Coffee in colonial Kenya began as a settlers' crop. A 2016 master's thesis on the history of coffee in Kiambu, the county next to Nairobi, records that coffee growing by Africans was prohibited there, and that attempts by Chief Koinange to plant it in the 1930s were unsuccessful. It gives the argument made for the ban, that Africans lacked the experience to produce the crop, and what it calls the underlying reasons: the settlers' fear of losing their labour and of competition in selling the crop. It dates the change to the early 1950s, though not to one year. Its abstract says that after the Mau Mau rebellion broke out in 1952 the colonial government was willing, with conditions meant to pacify the settlers, to meet African demands, and that a campaign by African chiefs for the lifting of the ban succeeded; its fourth chapter gives 1951 as the year Africans were allowed to grow coffee in Kiambu. Reforms under the Swynnerton Plan of 1954 consolidated land and issued title deeds, and growing cash crops became, in the thesis's words, increasingly lucrative. The thesis found that the first to benefit were the chiefs and headmen, and that growers later joined co-operatives to market their coffee.

That is one county, studied through archives and fifteen interviews, and CoffeeHQ has not read a national history. It is included because the thesis places the growth of African coffee co-operatives in these same years, and co-operatives now sell roughly four fifths of Kenya's coffee.

Pressures on the sector

• Drought. The attaché's 2026 report describes a severe drought that lasted up to March 2026, after which farms in the Mount Kenya region flowered robustly.
• Coffee berry disease, a fungal disease of green berries that favours cool, very humid conditions. A 2026 paper gives 15 to 25 degrees Celsius and air close to saturation as the conditions of its epidemics.
• Loss of coffee land to housing around Nairobi, Thika, Kiambu and Nyeri, which the attaché says slowed in the two years before its report because the property market stagnated.
• Planting material. The research institute cannot yet raise seedlings as fast as the planting programme asks for them.
• Land. Coffee near the towns has been uprooted for housing, and the attaché notes there is no land-use policy that protects it.
• Regulatory change. Rules for marketing and licensing were overhauled in mid-season in 2023/24, and a new Act and regulator arrived in 2026.
• Price exposure. The auction average fell by 28.4 per cent between October 2025 and April 2026.
• Disease. The older selections are susceptible to coffee berry disease, and seed of the resistant hybrid is laborious to produce.

The drought is one season's event as one report describes it. No Kenyan climate study or projection was read, so nothing is said here about how the climate of the growing areas is changing.

Institutions worth knowing

• Nairobi Coffee Exchange — the auction, founded in 1935, through which the USDA attaché says over 95 per cent of Kenyan coffee is sold
• Coffee Board of Kenya — the regulator re-established by the Coffee Act of March 2026, taking over from the Agriculture and Food Authority's Coffee Directorate
• Coffee Research Institute, Ruiru — the research station that bred Ruiru 11 and Batian; the 2026 Act sets up a Coffee Research and Training Institute separate from the national agricultural research organisation
• Capital Markets Authority — the financial regulator that oversees the exchange and licenses its brokers
• New Kenya Planters Co-operative Union — the body through which a government-supported revolving fund supplies saplings and fertiliser
