Country
Tanzania
Tanzania grows tea in three pockets hundreds of kilometres apart rather than in one belt, and the oldest of them is among the first places tea was tried in East Africa: German experimental plantings went into the Usambara mountains and at Rungwe from 1902. The country has never turned that into a name, and its tea is sold as anonymous bulk while its coffee is bought by origin. The recent change is the route to market. Tanzania opened its own tea auction in Dar es Salaam in 2023 rather than sending the whole crop to Mombasa.
What grows here
Black tea, and the map is three separate areas. The Southern Highlands are the bulk of it: Mufindi, Njombe and Rungwe around Tukuyu, on the high plateau north and east of Lake Nyasa. The Usambara mountains in Tanga region, inland from the coast, are the oldest planting and now the smallest, and they are where the country's specialty orthodox effort sits. The third is the Lake Victoria basin in Kagera, planted by the state after independence. Almost all output is CTC.
The ground
Most of Tanzania is too dry for tea, so the crop is confined to the few high wet pockets that can hold it. The Southern Highlands sit on the shoulder of the Rift, high and cool with a single long rainy season and a hard dry season behind it. The Usambaras are block mountains that catch moisture off the Indian Ocean, above 1,000 m and misty year round around the Amani forest. The dry season has been lengthening across all of them, and the Tea Board is running pilot irrigation schemes in response.
The bushes
Assamica, seed-grown at first and clonal from 1964. What the industry actually talks about is age rather than variety: much of the smallholder planting dates from the 1980s, yields are low and plots carry gaps where bushes were uprooted and never replaced. Large nurseries at Korogwe, Lushoto, Lupembe, Mpanga and Masebe-Mpugha were built to supply replanting material, which tells you where the constraint is.
Harvest seasons
Picking follows the rains and, unlike Kenya, there is a real off-season. The Southern Highlands have a single rainy season from roughly November to April and crop hard through it before falling away sharply in the dry months. The Usambaras take rain in two seasons and hold mist between them, so they pick closer to year round.
How it is made here
CTC for the bulk, and the interesting part is who owns the exception. In Malawi the specialty and orthodox work sits inside one large estate. In Tanzania it sits with growers: the Sakare Specialty Tea Company, opened in the Usambaras in 2023, is smallholder-owned and makes orthodox whole-leaf black, green and specialty lots on site from leaf hand-plucked to two leaves and a bud. It is a tiny share of national output and the only part of it with a name attached.
What to look for
Tanzania has no origin reputation to trade on, so the label has to do the work: ask which of the three growing areas and which factory, because Mufindi and the Usambaras have almost nothing in common beyond a national border. Three quarters of the crop is exported in bulk and most of it goes into blends unnamed. The Dar es Salaam auction, which held its first sale in November 2023, was built as a regional hub taking teas from Burundi, Malawi, Uganda and the Democratic Republic of Congo as well, so clearing through Dar es Salaam is not by itself a statement of origin.
How it got here
German settlers planted the first experimental tea at Amani in the Usambaras and at Rungwe in 1902. Commercial planting followed under British administration from 1926, the first factory opened in Tanga region in 1930 and exports began in 1934. Africans were barred from growing tea before independence, so the entire smallholder sector is post-1961: the state Tanzania Tea Authority planted it and built factories in Kagera, Rungwe, Njombe and Tanga. Nationalisation then broke the estates, output fell heavily and the industry was returned to private hands between 1988 and 1993, with the Commonwealth Development Corporation buying a majority of the state's tea assets.
