SL-28 & SL-34
Scott Labs (SL) is the name of a laboratory hired by the Kenyan government in 1930 to research and catalog commercial types of coffee, depending on the drought resistance, productivity and quality of the cup. The laboratories collected data, assigned specific numbers to varieties, and reported that two of them, named SL-28 and SL-34, would be the best choice for the economy and agriculture. Both varieties originated from Bourbon species: SL-28 from Tanganyika Drought Resistant II from northern Tanzania, and SL-34 from French Mission.
SL-34 though has an outstanding taste, among coffee-lovers it is appreciated less than SL-28. Tropical aroma, juicy body and dazzling acidity distinguishes this variety from others and becomes No. 1 among connoisseurs.
