Arusha takes its name from the Tanzanian town near Mount Meru, and its lineage is disputed — described variously as a Typica selection and as French Mission Bourbon.
Where it grows
Tanzania, where it originated, and Papua New Guinea, where it is one of the principal varieties alongside Blue Mountain-derived stock.
The cup
Sweet and balanced with a full body and moderate acidity. Approachable rather than distinctive.
French Mission
The name given to Bourbon distributed across East Africa by French missionaries in the nineteenth century. Much of the region’s old Bourbon traces to it, and the boundaries between named East African varieties are genuinely blurry as a result.
Brewing it
Filter or immersion at medium roast.
How Tanzanian coffee is sold
Tanzania grades its coffee by bean size: AA for the largest screen sizes, then A and AB, with PB for peaberries, the single round beans that form when only one seed develops in a cherry. A bag labeled Tanzania AA or Peaberry says nothing about variety, so Arusha is usually named only by specialty importers. Most Tanzanian arabica grows on the slopes of Kilimanjaro and Meru in the north and in the southern highlands around Mbeya, and most is washed.
