The SL28 variety is a cornerstone of Kenyan coffee excellence. Developed by Scott Agricultural Laboratories (SL) in the 1930s, it was part of a breeding program aimed at identifying varieties that could thrive in the unique climate of Kenya while producing high-quality coffee. SL28 was selected for its drought tolerance and its remarkable ability to produce a cup that was far superior to the varieties commonly grown at the time.
What makes SL28 so special is its sensory profile. It is famous for its 'Kenyan' character: a vibrant, wine-like acidity, a heavy, syrupy body, and distinct of blackcurrant, tomato, and citrus.

In the specialty market, SL28 is often sold at a premium. Its reputation for quality means that it is frequently featured in competitions like the .

If you enjoy coffees that are bright, complex, and full of character, SL28 is a must-try. It is a testament to the power of plant breeding and the enduring legacy of Kenyan coffee production.
