Distances in Tanzania are vast - there's almost 1000 kms between coffee producing regions in the North and in the South, same for East and West. The altitudes are up to almost 2000 MASL in many places. 90% of coffee producers are smallholder farmers, owning between 0.5 to 3 hectares, and less than 10% of the coffees are grown at estates.
Similar to Kenya, coffee came with the French missionaries in the late 1800s, and was planted around Tanzania  for the most
part (there are the Bourbon varieties that are often seen as SLs in Kenya now). In Tanzania, with its Indian influence, the Indian Kent varieties came from Mysore in the 1920s. In general, there are two varieties widely used today, the Bourbon-descended N39 hybrid, and the Kent hybrid KP432, as well as Kent varieties K7 and K9.
