What’s New:

This is our first year offering coffee from Kenya Karogoto.

The Process

Located about 100 miles from Nairobi in the Nyeri district, Karogoto Factory is a washing station at the foothills of the volcanic Mount Kenya and the Aberdare mountain range. In 2005, Karogoto Factory merged with Ngunguru Factory and Tegu Factory to form the Tekangu Farmer Cooperative Society, or FCS. We’ve worked with both Ngunguru and Tegu since 2008, but this is our first offering from Karogoto.

In Kenya, farmers deliver their coffee cherry to a member-run washing station, known as a factory, where the coffee is processed. This region, often referred to as the ‘home of Kenyan coffee’, is known for its abundant rainfall and fertile soils which are rich in organic matter and provide good drainage and aeration. SL28 and SL34 are the predominant varieties grown by farmers in the area.


More Details

Both SL28 and SL34 were created by Scott Laboratories (SL) in Kenya during the 1930s. When SL crossbred Bourbon, Mocha and Yemeni Typica in an attempt to create a high quality, high yield, disease resistant strain, they produced SL28. SL28, unlike the preset conditions SL wanted, has a low yield. Yet the consistent high quality cup that results overrode precepts and earned SL28 a solid place on the Kenyan coffee landscape.

SL34, a mutation of Bourbon, has bronze tipped leaves which differentiates it from its predecessor, SL28, and leads us to believe that it has a closer lineage to the Typica variety than the SL28. SL34 remains known for producing top quality at medium to high altitudes.
