Kericho
Kericho is where Kenyan tea is grown at industrial scale. The county sits on the western edge of the Mau Forest escarpment and holds the country's largest contiguous estates, each with its own factory, housing and roads, with smallholder factories filling the ground between them. It rains here most afternoons and it hails often enough to count as a routine crop hazard rather than a freak event. Kenya's tea research station is here too, so most of the clonal material planted across the country was selected on this hillside.
What grows here
Black CTC almost to the exclusion of everything else, made in estate factories that stand inside the fields they serve. A modest orthodox line runs alongside it on some estates, and that whole-leaf material is what reaches specialty buyers with a Kericho name attached. Purple tea belongs to this place by breeding rather than by volume: the cultivar behind it was released from the research station outside town, not from any particular garden here.
The ground
The Mau escarpment, roughly 1,800 to 2,200 m, facing west across the Rift. The Mau Forest behind it is the catchment feeding the rivers that cross the county, which is why Kericho has water where other Kenyan highlands are short of it. Rain falls through most of the year rather than in two clean seasons, usually in the afternoon, and the same convection brings hail. Deep red volcanic soil and no dormancy complete a set of conditions that give some of the highest yields per hectare anywhere, though a cold clear night in the dry months can still put frost on the fields.
The bushes
Clonal assamica, and this is where the clones come from. The national tea research station sits at Timbilil outside Kericho town and has been selecting and releasing numbered clones for decades, TRFK 306/1 among them. Estates and smallholders across Kenya are largely planted with material bred here. Seedling tea survives in patches from the earliest plantings and is now a small minority.
How it is made here
Kericho is where Kenya mechanised. Harvesters were brought onto the big estates to cut labour costs and they took thousands of plucking jobs with them, which has made this the most contested ground in Kenyan tea. A machine cuts a coarser and less even leaf than a two-leaves-and-a-bud pluck, which matters little once the leaf goes through CTC rollers and matters a great deal to anything orthodox. The factories are on the estates, so cut leaf is in the withering troughs within an hour or two.
What to look for
Kericho is a county rather than a garden, and it covers two entirely different production systems. Estate tea comes from a named plantation with its own factory. Smallholder tea from the same county goes to a Kenya Tea Development Agency factory and is pooled across thousands of one-acre farms. Both are honest and they are not the same product, so ask which one you have. Ask also whether the leaf was hand-plucked or machine-cut, because on Kericho estates the answer is increasingly the latter and it sets a ceiling on what an orthodox lot from here can be.
How it got here
Commercial planting began in the 1920s, when Brooke Bond and James Finlay laid out estates on land taken from Kipsigis communities, and those seizures are still the subject of live claims against the British government and the companies' successors. The scale set then never changed: the estates stayed large, foreign-owned and vertically integrated. Ownership turned over in the 2020s, with Unilever selling its tea business and Finlays selling its Kenyan estates, but the fields and the factories are the ones the colonial companies built.
