Siomo Tea Factory (Epz) Ltd is a black tea producer operating in the Bomet region of Kenya. Situated at 2,001 metres above sea level, the estate is operated by Siomo Tea Factory (Epz) Ltd itself and is recorded as supplying Finlays, one of the established names in the global tea trade.
Terroir & Climate
At 2,001 metres, Siomo Tea Factory occupies a high-altitude position within Kenya's tea-growing belt, just south of the equator. Estates at this elevation in the Kenyan highlands typically experience cooler temperatures and a more pronounced diurnal range than lower-altitude gardens, factors that tend to slow leaf maturation and can contribute to greater concentration of flavour compounds in the harvested flush.
The Bomet region generally receives well-distributed rainfall throughout much of the year, a pattern common to Kenya's western highlands, and the volcanic soils prevalent in much of the country's tea country tend to offer good drainage and mineral content. These conditions often support year-round cropping, though estates at this latitude and elevation usually see some seasonal variation in flush intensity tied to rainfall and temperature shifts.
Tea Produced
Siomo Tea Factory produces black tea. Kenyan blacks from high-altitude estates in regions such as Bomet are generally known for bright, brisk cup profiles with notable body and a characteristic coppery colour. Teas grown above 2,000 metres in this part of the highlands often exhibit pronounced astringency and a clean, malty character, qualities that have made Kenyan leaf a staple in blends for both the UK and international markets.
Supply Chain & Market Position
Siomo Tea Factory is recorded as supplying Finlays, a vertically integrated buyer with a significant presence in Kenya's tea sector. Finlays operates its own estates and also sources from independent factories, acting as both producer and merchant. The relationship suggests that Siomo's output meets the quality and volume specifications required by a buyer serving major branded and retail customers worldwide, positioning the factory within the commercial mainstream of Kenyan black tea supply.
