From the roaster

Coffee from Illam is grown on steep hillside farms by smallholder producers, where coffee is often cultivated alongside tea, cardamom, and subsistence crops rather than on large estates. Introduced only in the mid-20th century, Nepal remains a tiny, emerging coffee origin focused more on quality than scale. We partnered with passionate producers to bring you this distinctive lot, processed as a natural and enhanced with an anaerobic environment.

Onyx Coffee Lab

Context

Onyx Coffee Lab sources this lot from Nepal's Illam region, a traditionally tea-growing area increasingly known for specialty coffee. The anaerobic natural processing method — where fermentation occurs in sealed conditions before drying — creates an intensified flavor environment. Natural-processed coffees typically develop heavier fruit expression and more viscous mouthfeel than washed counterparts, and anaerobic fermentation amplifies these fermented and complex characteristics. This lot represents an interesting convergence of origin and method, combining Illam's emerging coffee profile with a processing technique designed to push aromatic boundaries. Reference the flavor wheel to explore how the tasting notes emerge from this specific combination.
