Chemusian Tea Factory

Chemusian Tea Factory is a black tea estate located in the Nakuru region of Kenya, operating at an elevation of 2,437 metres. The factory is operated by Chemusian Tea Factory and is known to supply Finlays, a major name in the global tea trade.

Terroir & Climate

At 2,437 metres, Chemusian sits at a high elevation even by Kenyan standards, positioning it well within the cool, high-altitude zones that typically shape the country's premium tea output. Estates at this elevation in East Africa generally experience significant diurnal temperature variation, with warm days and cool nights that tend to slow leaf growth and encourage the accumulation of secondary metabolites associated with complexity and briskness in the cup.

The Nakuru region's latitude, close to the equator, typically allows for year-round tea cultivation, though seasonal rainfall patterns often influence flush intensity and plucking cycles. High-altitude sites in this zone are generally subject to intense solar radiation and well-distributed moisture, conditions that tend to favour the development of the bright, coppery liquors for which Kenyan black tea is known internationally.

Tea Produced

Chemusian produces black tea, the dominant style across Kenya's high-elevation factories. Teas from estates at this altitude in Nakuru typically yield a brisk, clean cup with pronounced brightness and a coppery-red infusion. The profile that high-grown Kenyan black teas often display—vivid astringency, malty body, and a finish that carries both sweetness and grip—is generally well suited to blending and to markets that prize strength and colour, particularly in the CTC format that dominates Kenyan production.

Supply Chain & Market Position

Chemusian Tea Factory is recorded as supplying Finlays, a vertically integrated tea group with sourcing, blending, and packing operations spanning multiple origins. Finlays' involvement signals that Chemusian's output meets the quality and volume thresholds required by a global supply chain serving branded packers and foodservice buyers. This connection positions the factory within the export-oriented tier of Kenya's tea sector, where consistency, traceability, and compliance with buyer specifications are typically paramount.
