Soil Profile

The soils of Meru are deep, well-drained volcanic loams derived from the Mount Kenya volcanic system. These fertile red volcanic soils are rich in minerals and exchangeable potassium, providing ideal conditions for Arabica cultivation. The Kikuyu red and dark red loam soil series dominate the region, offering excellent drainage, optimal water retention, and ideal acidity levels (pH 5.5–6.5) that coffee trees thrive in.

Acreage & Farmers

Meru's coffee sector is dominated by smallholder farmers organized into cooperative societies. The Meru Central Coffee Cooperative Union alone unites 48 cooperatives representing approximately 98,000 smallholder farmers. Across the county, thousands more farmers are organized into hundreds of Farmer Cooperative Societies (FCS). Total coffee acreage in the county exceeds 15,000 acres, supporting millions of coffee bushes.

Kathangari Farmers Cooperative Society operates Kathangari Factory, serving farmers in the Kathangari location.

Varieties Planted

Meru farmers cultivate primarily SL28 and SL34 (approximately 80%), complemented by Ruiru 11 and Batian. SL28 and SL34 were released by Scott Agricultural Laboratories in the 1930s and 1940s and remain the cultivars of choice for most Kenyan growers due to their deep root structures, which allow them to maximize scarce water resources.

Processing

Coffee is fully washed using traditional Kenyan methods. Smallholders selectively handpick only ripe cherries and deliver them to factories within hours. After pulping using disk pulpers, coffee undergoes fermentation for approximately 12 to 16 hours, followed by a 24-hour soaking in clean water before being dried on raised beds for 15 to 21 days. This meticulous processing enhances clarity and complexity.

Cup Profile

Meru coffees are characterized by currant, cardamom infusion, orange juice, white grape juice, and lemon tea. The Ngonyi Factory lot delivers a distinctive combination of citrus and floral notes, along with a hint of black tea and white grapes. The cup exhibits bright acidity, medium body, and a clean, lingering finish that typifies the Eastern Kenya profile.

Soil Profile

The soils are volcanic red clays—mineral-rich, well-drained, and slightly acidic—characteristic of the Mount Kenya volcanic belt. These soils are deep and well-drained, derived from basic volcanic material, and rich in iron and aluminum oxides. The deep red volcanic loam contributes to the distinctive flavor complexity Tharaka Nithi coffees are famous for.

Acreage & Farmers

Coffee farming is smallholder-based, with farmers organized into various cooperative societies. Over 1,500 farmers deliver to the Mitheru Farmers' Cooperative Society alone. The Kirubia Co-operative Society works with nearly 1,300 members. Most farmers cultivate 0.5 to 2 hectares, typically intercropped with maize, bananas, and vegetables.

Varieties Planted

Machakos farmers cultivate SL-28, SL-34, Ruiru 11, and Batian. The region's high altitudes and volcanic soils are particularly well-suited to SL28 and SL34, which produce the complex cup profiles that Kenyan coffees are famous for.

Processing

Fully washed and dried in raised beds. Kenya is known for meticulous processing—bright white parchment, nearly perfectly sorted by density and bulk conditioned at high elevations. Machakos also produces a "fly crop" (secondary harvest) following the short rains, providing fresh crop coffee in the early fall. This bimodal harvest advantage gives Machakos two sourcing opportunities per year.

Cup Profile

Machakos coffees offer a distinctive profile: blossom, key lime, mixed citrus, key lime pie, lemon tart, orange marmalade, and lilac. Kaliluni AA delivers lemon, rue, bergamot, currant, and floral notes. The Kaliluni Peaberry offers blackcurrant sweetness, bright grapefruit zest, and lively red currant acidity with a crisp, refreshing profile. Ngomano lot expresses black currant, ripe plum, refined black tea, lively acidity, layered sweetness, and a clean, elegant finish.

Soil Profile
