Retained on mesh size 7.2mm. Characterized by dense, high-altitude bean morphology, pronounced citric acidity, and complex floral aromatics sourced primarily from Nyeri and Kirinyaga.
Retained on mesh size 6.8mm. Combines high cup clarity with excellent structural integrity, offering balanced sweetness and reliable roast development for seasonal single origins.
Natural single-seed mutation sorted through specialized gravity tables. Delivers concentrated cup density, heightened fruit notes, and exceptional caramelization during roast profiling.
Warehousing and Hermetic Packaging
All SamFresh green coffee lots are packed at origin immediately following milling into standardized 60kg jute sacks fitted with high-barrier GrainPro hermetic liners. This preserves vital green bean aromatics, prevents moisture migration during maritime transit, and stabilizes water activity across seasonal temperature fluctuations.
Lots are maintained in temperature-controlled bonded warehouses in the United Kingdom and continental Europe. Standard dispatch for spot lots occurs within 24 hours of order confirmation, with full lot traceability documentation and physical pre-shipment cupping notes provided directly to roastery QA teams.
