The SL28 coffee variety is one of the most respected cultivars in specialty coffee, recognized worldwide for its character, complexity, and elegance in the cup. Originally developed in Kenya during the 1930s by Scott Agricultural Laboratories, SL28 quickly gained recognition for its exceptional cup quality and resilience, becoming a reference point for expressive, origin-driven coffees.
From its beginnings in East Africa, the SL28 coffee variety has captured the attention of producers and roasters seeking clarity, structure, and vibrant acidity. Its reputation is built not on yield, but on its ability to translate terroir into a memorable sensory experience.
Origin and history of the SL28 coffee variety
SL28 was originally selected in Kenya for its ability to withstand periods of drought while maintaining outstanding cup characteristics. According to World Coffee Research, the variety is known for its deep root system and its capacity to produce complex flavor profiles when grown under suitable conditions.

Over time, the SL28 coffee variety expanded beyond Kenya into other producing origins, where high elevations and careful management allow it to express new dimensions of its profile while preserving its defining traits.
SL28 coffee variety in Colombia
In Colombia, the SL28 coffee variety has found ideal conditions to showcase its full potential. High altitudes, volcanic soils, and stable microclimates enhance its bright acidity, clean structure, and aromatic complexity. While SL28 is not considered a high-yielding variety, its value lies in the quality it delivers when cultivated with careful, quality-focused management.
In the cup, SL28 offers juicy acidity, notes of red and dark fruits, structured sweetness, and a medium to silky body with a long, clean finish. These attributes make it especially appealing for filter brewing methods and expressive roast profiles that highlight clarity and complexity.
Expression over volume: SL28 at La Reserva
At Finca La Reserva, one of Cumbres’ long-term projects, SL28 is grown between 1,850 and 2,200 meters above sea level, within a farm designed to balance coffee cultivation with environmental conservation. Out of 380 hectares, only 60 are dedicated to coffee production, while the remaining land is preserved as natural reserve and carbon-focused projects.
This approach reflects how we work at origin, prioritizing long-term sustainability, traceability, and respect for the ecosystem. You can learn more about our philosophy and sourcing model on our About Us page:
