01 | Estate Introduction

Chania and Oreti Estates are Kenya's only large and medium-sized private coffee plantations, managed by the Harries family since 1904. Chania Estate and Oreti Estate border the Chania River, featuring dams and reservoirs spanning nearly 200 acres of land, with forests planted along the riverbanks 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 self-elected committee that meets monthly to discuss community safety, social, and health issues. Beyond 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 tailoring, mechanics, and woodworking, helping local residents earn a livelihood.

02 | Origin Introduction

Kenya Thika Plateau

Kenya is located in the Kiambu coffee-growing area of the central highlands east of the Great Rift Valley, with Thika being a secondary region. This area lies at the foot of the Aberdare mountain range, with red volcanic soil rich in organic matter. Thanks to the mild climate and moderate rainfall, coffee farmers in the Kiambu region can have two harvests annually - from May to July, and from September to December.

The Kiambu region has several large coffee estates, and small farmers work closely with their cooperatives. Most have their own processing stations, giving growers better options than the unified acquisition and sale of coffee. Farmers process their coffee at their own factories and obtain reasonable prices at auction.

Chania Estate's unique red volcanic soil, combined with suitable coffee-growing temperatures and rainfall plus an excellent natural environment, creates the distinctive flavor of FrontStreet Coffee's Kenya Thika Chania Estate French Mission variety.

03 | Green Bean Analysis

French missionaries brought Bourbon trees to Kenya around 1892-1893. This original Bourbon variety is known as the French Mission varietal, which has avoided scientific-style improvement during cultivation, preserving the most original flavor of Bourbon.

Kenya "SL28" and "SL34": Selected and bred from the Bourbon lineage by French and British missionaries and researchers in Kenya in the early 20th century, these varieties have adapted to Kenya's high-phosphate soil over the past century, nurturing Kenya's characteristic acidic aromatics. Top Kenyan coffees all come from these two varieties, but they lose their characteristic flavor when transplanted elsewhere.

Kenyan coffee grades are divided into seven levels based on bean size, with six grades based on flavor quality from top to bottom. Kenya's best coffee grade is Peaberry (PB), followed by AA++, AA+, AA, AB, and so on, in descending order. Premium coffee has a bright luster, delicious taste, and a slight wine aroma. In terms of flavor, "Kenya AA" is particularly well-regarded.

Graded by bean size:

Kenya's best coffee grade is Peaberry (PB), followed by AA, AB, and so on, in descending order.

PB (Peaberry): This grade is for small round beans - coffee cherries that grow only one bean instead of the usual two.

AA: A more common grade with larger beans, sized above 18 mesh or 7.22 millimeters. These beans typically fetch the highest prices.

AB: This grade combines A (16 mesh or 6.80 millimeters) with B (15 mesh or 6.20 millimeters) beans, accounting for about 30% of Kenya's annual coffee production.

04 | Processing Method Introduction

This FrontStreet Coffee Kenya Chania Estate French Mission Bourbon is processed using the natural method. During refined natural processing, the already rich and varied acidity of Bourbon coffee gains body and sweetness. This natural batch is limited in quantity - a coffee that relies entirely on natural climate conditions.

05 | Roasting Analysis

The beans have medium density, and we roast with medium heat, climbing steadily. The beans heat up quickly during roasting, so we reduce the heat at 150, 160, and 170 degrees C to extend the Maillard reaction time while avoiding overly rapid heating. First crack begins around 8 minutes 15 seconds at 186 degrees C; we simultaneously reduce the heat and open the damper to develop flavor, dropping the beans at 194 degrees C after 2 minutes.

Roasting Machine: Yangjia 600g semi-direct flame (roasting quantity: 300g)

Preheat the roaster to 170 degrees C before loading, damper set to 3. Start firing after 30 seconds, heat adjusted to 140, damper unchanged. Turning point at 1'28", maintaining heat. At 140 degrees C, reduce heat to 110 and open the damper to 4. At 4'20", the beans turn yellow, the grassy aroma disappears, and the Maillard stage begins; heat is reduced to 90, damper maintained at 4. At 150, 160, and 170 degrees C, heat is further reduced to 90, 70, and 50 respectively.

At 7'50", the Maillard stage completes, the bean surface shows wrinkles and dark markings, and the toast aroma turns to coffee aroma - the prelude to first crack. Pay attention to the sound of first crack. At 8'13", first crack begins, the damper is fully opened to 5, and heat is adjusted to 30. Post-first-crack development time is 2 minutes, dropping the beans at 194 degrees C.

This FrontStreet Coffee Kenya Chania Estate natural French Mission Bourbon has good flavor but a relatively high defect rate, so please sort carefully before roasting. The dry aroma offers natural fermentation, dried fruit, and vanilla notes. When slurping, you can taste caramel, vanilla, and mixed fruits with a solid juiciness. The aftertaste brings berries, rich jackfruit, and coffee flower aromas. The overall expression shows the wild regional character of Africa - a complex aroma best savored in small sips.

FrontStreet Coffee Recommendation

If this naturally processed Chania lot has you craving more sun-dried specialty coffee, FrontStreet Coffee's natural lineup is worth exploring. The FrontStreet Yirgacheffe Red Cherry uses only fully ripe cherries, dried whole on raised beds for about 27-30 days and turned regularly to prevent uneven heating; at a medium-light roast it offers elegant florals, bright acidity, pronounced tropical fruit, and a full fermentation-driven sweetness. The famous FrontStreet Huakui from Sidamo, also natural, shows a faint fermentation note, florals, citrus, and mango with a honeyed sweetness, cocoa, and a hint of spice.

Outside Africa, the FrontStreet 2013 Yunnan Typica - natural-processed at our own estate during the sunny harvest season - is slightly sweeter than a typical washed coffee, with balanced sweet-and-sour berry-like acidity, dried apricot, and brown sugar notes. And the FrontStreet Colombia Sidra goes further still, with a double anaerobic natural process that delivers dense tropical fruit: passion fruit, apricot, dried fruit, and grape, finishing with an almond-like note.
