Tanzania entered tea cultivation later than its East African neighbors — the country’s first commercial tea gardens were established in the 1920s and 1930s by British colonial interests in the Usambara Mountains — but its growing regions offer genuine alpine conditions that rival Kenya’s most celebrated highland zones. Unlike Kenya’s tea industry, which developed a powerful smallholder model and became an export juggernaut, Tanzania’s tea sector has remained smaller, more estate-dominated, and less visible internationally. This relative invisibility is both a commercial challenge and an opportunity: teas from Tanzania’s Southern Highlands in particular can be acquired at prices that reflect their actual production costs rather than premiums paid for celebrity origins, while delivering quality that genuinely competes with more famous African teas in blind evaluations.
In-Depth Explanation
Historical Development
Colonial origins:
Tea cultivation in Tanganyika (as Tanzania was known before 1961 independence) began in the 1920s when German-established agricultural experiment stations were converted under British Mandate authority after World War I. British colonial administrators, drawing on experience in India and Ceylon, introduced Camellia sinensis to the Usambara Mountains in Tanga Region, establishing the first commercial plantings that would become the Usambara highlands tea estates.
Post-independence development:
Following independence in 1961, Tanzania (formed by the union of Tanganyika and Zanzibar in 1964) nationalized key agricultural industries including tea. The Tanzania Tea Authority (TTA) managed the industry through the socialism-influenced ujamaa agricultural policy period until economic liberalization in the late 1980s and 1990s allowed partial privatization of estates. The Tea Research Institute of Tanzania (TRIT), established in 1961, has continued agricultural research, cultivar development, and technical support for the industry.
Southern Highlands development:
The Rungwe and Mufindi districts in the Southern Highlands developed somewhat later than the Usambara region; the Southern Highlands tea sector began significant development in the 1950s and expanded post-independence. Unilever’s tea operations in the area (including the Mufindi Tea Company, later privatized) established significant Southern Highlands production capacity.
Growing Regions
Usambara Mountains (Tanga Region):
- Location: Northeastern Tanzania, West Usambara and East Usambara ranges; Tanga and Kilimanjaro regions
- Elevation: 900–1,800 meters
- Climate: Two distinct wet seasons; cooler, misty highland conditions; significant biodiversity (Usambara forests are a globally significant biodiversity hotspot)
- Major estates: Herkulu, Lushoto-area estates; some smaller operations in the East Usambaras
- Character: Usambara teas tend toward fuller-bodied character; the lower average elevation (compared to Rungwe) produces teas with less of the bright high-altitude character and more robust body suitable for blending
Southern Highlands (Rungwe, Mufindi, Njombe Districts):
- Location: Mbeya Region and Njombe Region in southwestern Tanzania; Rungwe District adjacent to Lake Malawi (Lake Nyasa); Mufindi District in Iringa Region
- Elevation: 1,500–2,100+ meters — significantly higher than Usambara
- Climate: The Southern Highlands receive moisture from Lake Malawi; temperatures are genuinely cool at upper elevations; pronounced two-season pattern
- Major estates: Kibena Tea Estate (Njombe), Lusitu Estate, Mufindi Highland Teas, Rungwe Tea
- Character: High elevation (1,800–2,100m zones) produces bright, floral orthodox teas with some of the altitude-driven complexity associated with premium African origins; the Rungwe material in particular draws favorable comparison with fine Kenyan highlands teas
Kilimanjaro foothills:
Some smaller tea operations in the Kilimanjaro and Arusha regions; not a major producing area but contributes to the geographic spread of Tanzanian cultivation.
Industry Structure
Estate vs. smallholder:
Tanzania’s tea industry is significantly more estate-dominated than Kenya’s. While Kenya’s “smallholder model” (60%+ of production from small farms organized through the Kenya Tea Development Agency, KTDA) is widely cited as a development success story, Tanzania has a higher proportion of large estate operations. The Tanzania Smallholder Tea Development Agency (TSHTDA) has attempted to build smallholder participation, but estates remain central to production volume.
Key private sector players:
- Unilever Lipton Plantations: Historically significant owner of multiple Southern Highlands estates; partial divestment has occurred over time
- Eastern Produce (Tanzania) Ltd: Manages several Tanzanian estates
- Various smaller individual and foreign-owned estate operations
Processing capacity:
Tanzania has orthodox processing capacity at several estates — this is significant because it enables production of whole-leaf orthodox grades that can access specialty markets. Kenya’s CTC dominance (over 95% of Kenyan production is CTC) means Kenya rarely produces orthodox teas; Tanzania’s mix of CTC and orthodox creates market differentiation potential.
Tea Quality and Specialty Potential
Orthodox black tea:
Tanzania’s specialty tea potential is most visible in its orthodox black tea production from the Southern Highlands. High-elevation Rungwe and Mufindi orthodox teas produce bright, golden liquors with floral-fruity aromatic profiles; the altitude-driven slow growth concentrates secondary metabolites including theaflavins (responsible for brightness and astringency) and aromatic volatile compounds.
CTC for blending:
The majority of Tanzania’s production is CTC grade; Tanzanian CTC teas are exported primarily to Pakistan, Egypt, and other Middle Eastern markets where blended CTC tea is the dominant format. This volume production represents the industry’s commercial foundation.
Comparison with Kenya:
- Both countries share the East African Rift Valley geography creating highland growing conditions
- Kenya’s KTDA system and Cup of Excellence-style auction (Mombasa Tea Auction handles much of East Africa’s tea) gives Kenya major institutional visibility
- Tanzania’s teas are often available through the Mombasa Auction at competitive prices relative to equivalent-quality Kenya grades
- Tanzania’s smaller specialty tea community produces more opportunity for direct-trade engagement with smaller estates
Export Markets and Trade
Primary market:
The majority of Tanzania’s tea exports go to Pakistan, Egypt, the UAE, and the UK — markets primarily seeking affordable CTC black tea for blending purposes.
Specialty market development:
Several US and European specialty tea companies have developed direct-trade relationships with Southern Highlands estates; Tanzanian orthodox teas appear in specialty tea programs alongside better-known African origins (Kenya, Rwanda, Malawi).
Mombasa Tea Auction:
Most Tanzanian tea is auctioned through the Mombasa Tea Auction (Kenya) — the main East African tea clearing house; this may partly explain Tanzania’s lower visibility as a distinct origin, since its teas often enter the same regional auction channel as Kenyan teas.
Common Misconceptions
“East Africa means Kenya for tea.” Kenya is by far the largest East African tea producer (~70% of regional output), but Rwanda, Malawi, Tanzania, Uganda, and Ethiopia all produce significant volumes with distinct regional characters; Tanzania in particular offers genuine specialty tea potential that the Kenya-centric framing of “African tea” obscures.
“Tanzanian tea is all CTC for blending.” While CTC dominates production volume, the orthodox processing capacity at Southern Highlands estates produces high-quality whole-leaf teas competitive with premium African origins; the limitation is quantity and distribution, not quality.

Comparative quality analysis of tea products from large estate operations vs. smallholder farms across the East African region including Tanzanian Southern Highlands samples; evaluated theaflavin content, thearubigin ratios, and sensory tasting scores from trained panels; found that high-altitude Tanzanian Southern Highlands samples (Rungwe/Mufindi) produced theaflavin concentrations (2.8–3.4%) comparable to premium Kenyan highland grades, and scored above the East African average on brightness and flavor quality metrics when processed at properly maintained factories; provides the instrumental chemistry basis for Tanzania’s quality claims, showing that the Southern Highlands origin can achieve analytically verified premium-grade quality metrics when processing standards are maintained.
