| Origin Introduction
Coffee styles vary significantly across Kenya's counties, of which there are 47 nationwide.
The coffee characteristics of different counties are distinct. Kenyan coffee trees are mostly grown at altitudes of 1,400 to 2,000 meters, with two harvests per year. Growing areas include Ruiri, Thika, Kirinyaga, Mt. Kenya West, Nyeri, Kiambu, and Muranga, mainly on the foothills of Mt. Kenya and the Aberdare Range. For example, Embu coffee features balance, citrus fruits, chocolate, apple, and acidity. Nyeri coffee features white grape, juicy, grapefruit and cherry tomato flavors, full of fruitiness, and caramel-like sweetness.

Thika, Kenya
Thika is located in the Kiambu coffee-growing area on Kenya's central highlands east of the Great Rift Valley, and is a secondary region. It sits at the foot of the Aberdare Range, and its soil is red volcanic soil rich in organic matter. Thanks to a mild climate and moderate rainfall, coffee farmers in the Kiambu region can harvest two seasons per year—from May to July and from September to December.
KIAMBU
KIAMBU: This region in central Kenya has the highest-altitude coffee-growing area in the country.
The Kiambu region is home to several large coffee estates, and smallholders and cooperatives are closely connected. Most of them have their own processing plants, which provides growers with a better outlet than selling coffee through unified purchasing. Farmers complete green bean processing at their own factories and get reasonable prices at auction.
However, some coffee trees at high altitudes suffer from dieback and stop growing. This producing region is named after the town of Nakuru. Coffee here is grown both on estates and by smallholders, though production is relatively small.
Altitude: 1,850–2,200 meters
Harvest Period: October–December (main season), June–August (secondary season)
Varieties: SL-28, SL-34, Ruiru 11, Batian
| Estate Introduction
Chania and Oreti Estates are Kenya's only medium-to-large private coffee plantations, and the Harries family has managed coffee production on the estates since 1904. Chania Estate and Oreti Estate border the Chania River, with dams, reservoirs, and nearly 200 acres of land, while forest is planted along the riverbank to protect birds and wildlife.
The estate owner, Boyce Marquis Allen Harries, took over the family business of the Estates and A.I.R. (Harries & Son Ltd.) in 2013. Today, 40 employees work for Boyce, many of whom have served the Harries family for three generations. The employees have their own elected committee, which meets monthly to discuss community safety, social, and health issues. In addition to caring for their own workers, the Harries family has also donated land to the Thika City Council and co-founded Wabeni Technical College, which teaches practical skills such as garment-making, mechanics, and carpentry to help local residents make a living.
The Harries Story: This estate has a history of more than 100 years.
Chania and Oreti Estates are the only medium-to-large private coffee plantations in Kenya. In 1904, Alan Charles Harries arrived in South Africa and came to Kenya. After a thorough survey of the country, Alan Charles established Karamaini Estate within what later became Thika. It took him two days to cover the 30-mile journey from Nairobi by donkey cart and porters.
His third son, Aldred Ivan Rule Harries, remained in South Africa and helped support his father financially, eventually joining his coffee business in 1912.
In 1926, Ivan moved to Chania village. This was a mixed farm on the Chania River, holding a small area of coffee.
Here Ivan set out to discover what could be successfully farmed, trying hand-reared cattle, sisal, and pineapple while slowly increasing the total area of coffee. He also bought neighboring small farms to create the estate as it is today. In the early 1950s, based on his own initials, he named his business A.I.R. Harries & Son Ltd. In 1946, Ivan's son Peter Alan Harries completed his studies in New Zealand.
He and his wife Ina (a New Zealander) joined his father and bought a piece of land 5 miles above Chania, down the ridge from the Aberdare Mountains. They named it Oreti and established a mixed farm of pineapple, coffee, and macadamia.
Peter inherited the running of both farms in the late 1950s when his father died. The farm had pineapple, livestock, and macadamia, but coffee became the focus of the agricultural operation. When Peter died suddenly in 1983, his eldest and later only surviving son, David Hugh Alan Harries (b. 1947), stepped up under pressure to continue the family tradition.
David's nephew, Boyce Marquis Allen Harries (born in 1976), joined him in 2004 and lived in Peter's old home at Oreti. After David retired in 2013, Boyce took over the operation of both estates and the family business A.I.R. Harries & Son Ltd.
| Green Bean Analysis
French missionaries brought Bourbon trees into Kenya for cultivation around 1892–1893. This native Bourbon tree is called French Mission Varietal, and during cultivation it avoided scientific improvement, preserving Bourbon's most original flavor. The unique red volcanic soil of Chania Estate, combined with suitable coffee-growing temperatures and rainfall, along with an excellent natural environment, creates the distinctive flavor of the French Mission variety from Thika's Chania Estate.
Bourbon Variety
Let's briefly explain what Bourbon coffee is. Bourbon coffee was first planted on Réunion Island, which was also called Île Bourbon (le Bourbon) before 1789. Bourbon is a sub-variety produced by a mutation of Typica, and together with Typica it is one of the oldest surviving coffee varieties. Its green fruit turns bright red when ripe.
The Spread of the Bourbon Variety
Because the Typica variety introduced to Brazil in 1727 had low yields and was susceptible to disease, Bourbon was introduced to Brazil around 1860 via Campinas in the south and quickly spread northward to other parts of South America and Central America. In Latin America today, although Bourbon has largely been replaced by its variants (especially Caturra, Catuai, and Mundo Novo), Bourbon is still grown in countries such as El Salvador, Guatemala, Costa Rica, and Peru.
In Africa, French missionaries known as Spiritans (from the Congregation of the Holy Spirit) played an important role in spreading Bourbon. In 1841, the first mission was established on Réunion, and a branch was established in Zanzibar in 1859; from Zanzibar, branches were established in 1862 at Bagamoyo (on the coast of Tanzania, then called Tanganyika) and St. Austin (Kikuyu, Kenya), and another branch was established in 1893 at Bura (Taita Hills, Kenya). The establishment of each branch was accompanied by the planting of coffee seeds brought from Réunion.
In 1899, seedlings cultivated at Bura were taken to another French mission at St. Cruz (near Nairobi), and in 1900 they were introduced to Tanzania's Kilimanjaro region, where seeds were distributed to local residents willing to grow coffee. This is the origin of what is called "Mission Bourbon." Then the Kent variety was also introduced in 1920. Therefore, to this day, coffee in Tanzania is still mainly Bourbon and Kent.
Cupping Results
This coffee has good flavor, but the defect rate is relatively high, so please sort carefully before and after roasting. The dry aroma has naturally processed fermentation, dried fruit, and vanilla notes. On slurping, you can taste caramel, vanilla, mixed fruits, with a solid juicy mouthfeel. The finish has berries, rich jackfruit, and coffee floral notes. Overall, it shows a wild African regional flavor, suitable for slow sipping to savor, and its complex aromas are hard to let go of~
| Brewing Data
Recommended brewing method: Pour-over
Grind size: 3.5 (Japanese Fuji R440)
Water temperature: 90–91°C
V60 dripper, 15 g coffee, grind 3.5, water-to-coffee ratio close to 1:15
Bloom with 30 g water for 30 seconds
When the water level is dropping, the stream will follow the spiral ribs and concentrate the flow. This action is like wringing a towel, squeezing the coffee particles in the water all at once. To maximize this squeezing effect, the water level should never exceed the height of the coffee bed during pouring.
The second pour also starts from the center, injecting a thin stream into the bottom of the coffee bed. To keep the stream's penetrating force concentrated, the circular movement should be small, about the size of a coin, and then spiral outward. From the start of the second pour, pay attention to the water volume and try not to let the water level exceed the height of the coffee bed; that is, when the stream circles close to the filter paper, you can stop pouring.
Stages: pour to 120 ml and stop, then slowly pour to 225 ml, i.e. 30–120–75, with a total extraction time of about 2 minutes.
Other drip extraction suggestions:
French press: recommended grind size 3.5–4 / water temperature 90°C
AeroPress: recommended grind size 2.5, water temperature 90°C
Pour-over: grind size 3.5, water temperature 91°C
1. Weigh 20 g beans, grind to the size of coarse granulated sugar, and use a coffee-to-water ratio of 1:15.
2. Add water to the French press to preheat it, then pour it out; add the ground coffee to the French press.
3. Pour in 89°C hot water and start timing. After pouring, stir gently to make sure all the coffee grounds are saturated.
4. After four minutes, slowly press down the plunger and pour it out.
