OGEMBO (EBEREGE)

Ogembo (Eberege) is a black tea estate located in the Kisii region of Kenya, operated by the Kenya Tea Development Agency (KTDA). Situated at an elevation of 1,705 metres and positioned just south of the equator at latitude -0.677334, the estate forms part of Kenya's smallholder tea sector, which KTDA coordinates across the country's varied tea-growing highlands.

Terroir & Climate

At 1,705 metres above sea level, Ogembo (Eberege) occupies a mid-altitude position within Kenya's tea-growing belt. Estates at this elevation typically experience moderate temperatures and a diurnal range that can slow leaf maturation, often contributing to the development of compounds associated with briskness and colour in black tea. The Kisii region, located in the western highlands of Kenya, generally receives well-distributed rainfall across much of the year, a pattern that tends to support steady vegetative growth.

The equatorial latitude means the estate experiences relatively consistent day-length year-round, which in many Kenyan growing areas is associated with continuous cropping rather than the pronounced dormancy seen in more temperate tea regions. Soils in the western Kenyan highlands are often derived from volcanic parent material, which typically offers good drainage and nutrient availability—factors that tend to favour vigorous tea cultivation at mid to high elevations.

Tea Produced

Ogembo (Eberege) produces black tea. Kisii teas, grown at mid-altitude in equatorial conditions, generally yield a cup with the brisk, bright character for which Kenyan black teas are widely recognised. Estates in this region often produce leaf suited to CTC processing, which tends to deliver the strong colour, body and astringency favoured in blended breakfast teas and by buyers seeking bold, consistent liquor. The moderate elevation and year-round growing conditions typically result in teas with good strength and a clean, straightforward profile.

Operator

The estate is operated by the Kenya Tea Development Agency, a co-operative body that manages smallholder tea production across multiple regions of Kenya. KTDA coordinates processing, quality control and marketing on behalf of tens of thousands of smallholder farmers, linking remote growing areas to the Mombasa auction and international buyers. The agency operates six other estates recorded in this directory, underlining its extensive reach within Kenya's smallholder tea sector.
