Like the SL28 variety, the SL34 variety was developed in the 1930s SL34 in Kenya at the Scott Agricultural Laboratories - hence the name SL - as a mutation between Bourbon and Typica. The difference with the SL28 variety lies in the color of the leaves. While SL28 has leaves with copper-colored tips, these are bronze-colored in SL34.
The SL34 variety is known to be very resistant to heavy rains at high elevations.It is a rather heavy cup profile with a complex citric acidity.
