Context

This offering from Onyx Coffee Lab features the SL28 varietal, a plant selection originally developed in Kenya that is now cultivated by the producer Volcan Azul in Costa Rica. While SL28 is historically celebrated for its distinct acidity and complex, blackcurrant-like profile, its performance in Central American volcanic soil offers a unique perspective on how terroir influences this specific genetic lineage.

When evaluating the nuances of such a specific lot, it is helpful to reference the flavor wheel to categorize the diverse aromatic compounds present in the cup. Because SL28 is known for its high-toned, vibrant character, it often stands out in a lineup of more traditional regional varieties. By focusing on the intersection of Kenyan-derived genetics and Costa Rican cultivation, this coffee provides a compelling study in how varietal expression adapts to new environments, inviting drinkers to explore the boundaries of traditional regional profiles.
