SL 14 Coffee Variety
It was originally selected in Kenya the late 1930s at the Scott Agricultural Laboratories (for more on Scott Labs, see SL28). Individual tree selections made at the Scott Laboratories in Kenya during the 1935-1939 period were prefixed “SL.” SL14 was selected in 1936 from a single tree labeled Drought Resistant II (D.R. II), and drought tolerance is a noted characteristic of SL14. Historical records documenting the origin of D.R. II were lost, but the seedlings were established at Kabete in 1933, and then widely distributed in areas east of the Rift Valley in Kenya.Recent genetic tests have confirmed that SL14 is related to the Typica genetic group. It is economically important in both Kenya and Uganda.

SL 28 Coffee Variety
It is among the most well-known and well-regarded varieties of Africa. It has consequently spread from Kenya, where it was originally selected in the 1930s, to other parts of Africa (it is important in Arabica-growing regions of Uganda, in particular) and now to Latin America. The variety is suited for medium to high altitudes and shows resistance to drought, but is susceptible to the major diseases of coffee. SL28 is notable for its rusticity—a quality meaning that it can be left untended for years or even decades at a time, and then return to successful production.

Natural Process
Process Details
-The cherries are selectively harvested at peak ripeness, ensuring a dark red color before being delivered to Nyabirongo station.
-The coffee undergoes a natural process with a 48-hour fermentation period. It is then sun-dried on raised beds in thick layers, later spread out in thin layers with constant turning until fully dried.
-Once the drying process is complete, the beans are hulled, graded, and color-sorted before being packed for export. The drying process is carefully managed to preserve the beans’ distinct flavors. Coffee is stored in a dedicated warehouse on pallets, maintaining its quality before export.
