N39 Coffee: Tasting Tanzania’s Arabicas
Tanzanian coffee is known for its rich flavour and wine-like acidity. If you’re a fan of Tanzanian coffee, you need to try the N39 variant. Trust me, it’s more exciting than the name suggests.
Let’s learn about N39 coffee.
What is the N39 variant?
N39 is a strain of a Bourbon variety developed by the Tanzania Coffee Research Institute (TACRI). It’s a tall varietal that shows tolerance to some diseases and gives a good cup quality. These plants are resistant to CBD (coffee berry disease) (1) and CLR (coffee leaf rust) (2). Pretty tough little things, right? N39 was developed in the 1930s and intended to improve the production of coffee in that region.
N39 carries lively acidity with a rich body and a complex taste profile. It typically carries notes of almonds, honey, red berries, and apricots, but the flavour and aroma profiles change depending on where the coffee is grown (north vs. south). In terms of brewing, it’s best suited for espresso, with or without milk. You can also brew it using the filter brewing method such as Chemex or pour over.

Tanzania’s Coffees
Tanzania produces Arabica and Robusta coffee and exports more than 90% of it. N39 primarily grows in Mbeya, Ruvuma, Songwe, and Arusha regions. All of them are situated in the Southern Highlands of the country.
In recent years, the consumption of coffee in Tanzania has increased, but in spite of this, the local café Union Coffee in Moshi, where the coffee was also roasted, most of clients was tourists.
The coffee grows at an altitude of 1,500 metres above sea level. Some N39 also grows on Mount Meru and Mount Kilimanjaro, which lie in the northern areas of the country.
Harvest months run from July to December in the north as well as the south. This harvest season is the same as Kenyan coffee.
Once the beans are picked, processing can be difficult for local farmers who are geographically far from washing stations. Some farmers depulp using their hands and process the beans themselves. The ones who are closer to washing stations can send cherries to pulping units.
Northern coffee vs Southern coffee
Coffee from the northern regions has a comparatively pleasant aroma and a rich mouthfeel and acidity. It also offers a sweeter and more balanced taste. This is because of the mineral nutrients present in the volcanic mountain soils of the area. On the other hand, southern coffees have a medium body with lively acidity. They have floral and fruity aromas and flavours.
N39 Sub Varietals
The N39 has several sub-varietals and all of them produce a clean cup with good acidity, body, flavour, and aroma. Apart from N39, the area also produces Nyassa and some experimental varietals such as SC11, SC 3, and KP 423.
As coffee was brought to Tanzania by Réunion, a Bourbon-producing French island, N39 also has its roots in France, making it a French mission variety. Coffee came to Tanzania in the 16th century, but it received attention only after the German missionaries started arriving almost 200 years later.
Additionally, N39 is also a cultivar of Bourbon, Arabic’s hybrid with a deep chocolatey, buttery flavour profile. Because of that N39 carries slight notes of chocolate and nuts.
