Terroir & Climate
At 2,432 metres, Tachasis occupies one of the higher altitude zones for tea cultivation in Kenya. Estates at this elevation typically experience cooler temperatures and more pronounced diurnal variation than those at lower altitudes, conditions that generally slow the growth cycle and can encourage a more gradual development of flavour compounds in the leaf.
The Olenguruone area lies in Kenya's Rift Valley highlands, a region where volcanic soils and reliable rainfall patterns tend to support year-round tea production. High-altitude sites such as this often benefit from mist cover and moderate daytime warmth, environmental factors that are generally associated with reduced stress on the tea plant and a finer leaf structure.
Tea Produced
Tachasis produces black tea. Kenyan teas from high-altitude estates typically yield a bright, brisk cup with good body and a clean, astringent character. The elevation at which Tachasis is situated tends to favour teas with clarity and a pronounced malty or floral profile, though cup character will vary with manufacturing method, plucking standard, and seasonal conditions.
Supply Chain & Market Position
Tachasis is recorded as supplying Finlays, a vertically integrated business with tea estates, blending facilities, and a global distribution network. This relationship places the estate within a supply chain that serves international tea brands and retail buyers, suggesting that its output is destined for blended products rather than single-origin retail. Finlays' presence as a buyer indicates that Tachasis meets the quality and volume standards required by large-scale commercial operators.
