N39 is a Tanzanian selection developed at the Lyamungu research station on the slopes of Kilimanjaro.
Why it was selected
Yield and some disease tolerance, with acceptable cup quality — the usual national-programme balance.
The cup
Clean and balanced with moderate acidity and medium body. It contributes to the bright, citric character of northern Tanzanian coffee without the intensity SL28 brings.
Where it grows
Widely across Tanzania, alongside Bourbon, Kent and other selections. Most Tanzanian lots contain a mixture.
The Tanzanian programme
Lyamungu has produced several selections, and Tanzania has more recently released rust-resistant hybrids in response to the same disease pressures Kenya faced.
Brewing it
Filter, light to medium roast.
