Tanzania Coffee Origin Guide: Regions, History & Flavor Profile

Tanzania produces over a million bags of coffee annually, enough to rank in the top twenty in global coffee production, with both arabica and robusta planted throughout the country. Robusta was well known to indigenous groups prior to colonization, but arabica was introduced in 1868 from the island of Réunion. Estate production is common in developed regions in the north of the country, while smallholder production is dominant in the south and west. Much of the country’s coffee passes through a national auction. The country is well-known for its peaberry selections, and washed coffee is the most common processing type for specialty arabica.

History

History

In Tanzania’s far northwestern coffeelands, the Haya people of what is now the Kagera region, bordering Rwanda and Burundi, cultivated indigenous robusta. The Haya boiled and smoked the coffee fruits, and often exchanged them as gifts and forms of currency.  

Europeans brought Tanzania arabica as early as 1868, first arriving from the French-held island of Réunion, where the local Spiritan bishop resided. Zanzibar’s Sultan gave the European missionaries his blessing, and shortly thereafter the Spiritans made their way to Bagamoyo on Tanzania’s central coast. The local leadership offered the Catholic sect some land, purportedly to aid the survivors of slavery. By 1877 Bagamoyo’s Catholic population was booming and the school had a garden where coffee from Réunion, Madagascar, and India was grown.  

Colonial governments like the Germans, beginning in 1885, and the British after them, attempted to force arabica production as a cash crop on the Haya and other regional groups. The Haya offered the strongest resistance, uprooting arabica trees in acts of defiance.  

Arabica took root more easily near Kilimanjaro, spread by the Spiritan missionaries in the early 1890s. Arabica was planted in 1902 in Moshi and cultivated by the local Chagga group, under colonial duress. This established a local economy that eventually organized into a coffee auction system, still in place in Moshi today.  

After the first World War, the British absorbed what was then called German East Africa and renamed it Tanganyika, accelerating coffee cultivation. The first cooperative, the Kilimanjaro Native Planter’s Association, was established in 1925. It was the first of several cooperative groups enabling producers to directly sell the coffee to London and get better prices. After the second war, any remaining Germans settlers would be interned, and farms were taken over by the British.  

After Tanganyika’s transition from British colony to UN trustee territory, a series of elections in the late 1950s culminated in the rise of educator and anti-colonial politician Julius Nyerere, who became the nation’s first president. In 1963, Zanzibar joined Tanganyika to form the United Republic of Tanzania (a portmanteau of the two previously independent nations). 

In 1977, in an effort to unify one of Africa’s most ethnically and linguistically diverse countries, President Nyerere introduced a new philosophy called “Ujamaa.” The Swahili word can be rendered in English as “family” or “brotherhood” but has come to mean “cooperative economics” or “socialism.” Under this ideology, Tanzania rapidly nationalized former colonial holdings and redistributed lands and properties. 

Unfortunately, agricultural cooperatives, including the 400 or more coffee co-ops, began to dissolve under the weight of a ballooning bureaucratic government which was rife with corruption. For half a decade, from 1977 until 1982 when cooperatives reorganized under governmental control, the Tanzania Coffee Authority bought and sold all coffee in the country. As subsidized government-controlled cooperatives sank deeper into debt, independent parties were able to step in where cooperatives lacked assets and began to purchase coffee directly. 

The Tanzania Coffee Board (TCB) was first established during a series of reforms and privatization beginning in 1990 and culminating with the formation of the Tanzania Coffee Research Institute (TaCRI) and the TCB in 2000-2001. 

The TCB Auction held in Moshi, in the far northeastern part of the country, takes place weekly during the harvest season. Bidders are licensed by the government to participate as exporters to the international market. In recent years, additional decentralized auctions have also taken place in Kagera (in the northwest) and Mbinga and Songwe (in the south). 

A shift in the country’s approach to the cooperatives began somewhat recently in January of 2018, largely as an effort to curtail high rates of robusta smuggling. All licenses for traders purchasing coffee directly from farmers were revoked, and legislation reinstated smallholder cooperatives (unregistered groups are no longer allowed) and mandated all coffee be purchased by exporters exclusively through the auction, effectively eliminating the possibility of direct trade from farmer to exporter.  

Cooperatives were left with little time to prepare for the upcoming harvest, and multinational and private buyers completely pulled up roots, abandoning their now-illegal washing stations and dry mills. Unpicked coffee fruits spoiled on the trees, and export-ready coffee arrived late to auctions and markets that year. 

After 2018’s coffee volumes in Tanzania dropped, PM Majaliwa backpedaled, reinstating the possibility of international direct exports, requisitioning additional seedling plantings, floating the concept of regional auctions, and banning the export of unprocessed coffee in January of 2019. The country has since partnered with Cafe Africa, an NGO seeking to train farmers and agronomists. 

Production

Production

During the early and mid-1990s reforms were put in place to create an easier pathway for direct trade. Coffee wilt disease spread throughout Tanzania and Uganda during this period as well and created major setbacks for the industry. Roughly 320,000 small-holder farmers produce approximately 90% of the coffee from the country. About 100 larger estates also exist in the country and the make up the last 10% of the coffee grown. Of this production volume, around 60% is arabica and the remaining is Robusta. Production overall for the 2025/2026 year is predicted to hit 1.35 million 60kg bags, little changed from the previous year. However, robusta is driving production and volume is up. Direct consumption is lower than other east African countries as 77,000 bags a year, with tourism and restaurant sectors as primary consumers. The EU is Tanzania’s largest customer, followed by Japan. 

Coffee typically harvests beginning in May-August in the south of the country, and July-November in the north. The weekly auction opens in August, with exports becoming available as early as September through the early months of the next calendar year. 

Peaberry is a common offering that is grown in Tanzania, a naturally occurring genetic anomaly of the coffee bean that causes the seed to have a single developing seed. Typical arabica trees produce about 5% peaberry beans worldwide, but Tanzania has carved a niche market in the US for its peaberries, likely used in early marketing to second and third wave roasters as a way to differentiate Tanzanian coffee from its occasionally higher-profile neighbor, Kenya. 

As in Kenya, the British grading system is standard practice in Tanzania, assigning AA, AB, and Peaberry, et al, as a measure of bean size.

Regions

There are three primary macro-regions of Tanzania where coffee is grown: the West Lake Zone, the Northern Highlands, and the Southern Highlands. 

In the northwest along the border with Uganda, Rwanda, and Lake Victoria, we see coffee in the West Lake Zone, often designated as Kagera, the name of the primary administrative region in the area. Much of the country’s robusta is produced in Kagera. Tarime coffee is a less recognized but still relevant coffee origin, the name of a large town in the Mara region on the east side of Lake Victoria.  Coffee also grows a little further south in the Kigoma region near the border with Burundi near Lake Tanganyika.  

The Northern Highlands represent coffee grown in the Arusha and Kilimanjaro administrative regions, some of the oldest commercial coffeelands in the country. With a higher percentage of estate coffee in the area, and set against the indominable backdrop of Mount Kilimanjaro, these are often the most recognized sources of Tanzanian beans to international buyers. The town of Moshi, which hosts the coffee auction, rests in Kili’s southern foothills, while coffee grown west of Mount Meru and Arusha town, in districts of Karatu and Oldeani, border the safari destinations of Lake Manyara and the Ngorongoro crater.  

Tanzania’s southern highlands span a much wider reach of geography in the country’s agricultural heartland bordering Malawi, Zambia, and Mozambique. Coffee grown in the largely rural administrative regions of Mbeya and Ruvuma is primarily harvested and processed by smallholders and cooperatives, and production here has largely increased in recent years. Recognizable coffee producing districts include Rungwe, Mbozi, and Ileje within Mbeya, and Songea and Mbinga in Ruvuma.   

Coffee typically ships through Dar Es Salaam, Tanzania’s capital city, which handles roughly 90 percent of the country’s trade volume. Main alternative ports exist in Tanga on the north Indian Ocean coastline, and Mtwara in the south. Dar Es Salaam also exports substantial volumes of Rwandan and Burundian coffees. 

Cultivars

Cultivars

Bourbon was the first arabica planted in the country, and has substantial local populations and selections. Notable cultivars in the Bourbon group include N39 (selected and developed by TaCRI) and K7 (a Kenyan selection made by Scott Labs in 1936). 

SL28, also a Scott Lab selection, was first selected from Tanzania for drought resistance, but is most famously grown in nearby Kenya with only limited populations in Tanzania. 

Kent, once thought to be a Typica tree, is genetically confirmed as a Bourbon relative. It was another early arrival, first selected in India, it can be found throughout Tanzania. In later years, KP423 was selected from Tanzanian-grown Kent trees, though it is more popular in Uganda.
