Colombia Doña Martha Gesha

El Diviso has become one of the defining names in modern Colombian specialty coffee, known for pushing processing innovation while maintaining clarity and balance in the cup. This washed Gesha immediately stood out to us on the cupping table for its remarkable florals and refined structure, offering a more elegant and articulate expression of the Lasso brothers’ work while still carrying the complexity and vibrancy they are known for.

Geisha is one of specialty coffee's most celebrated varietals, widely prized for its delicate floral aromatics and tea-like transparency — characteristics that have made it a fixture at the highest levels of competition and connoisseurship. When grown in Colombia's complex microclimates, it often expresses that signature clarity with notable brightness.

The anaerobic washed process adds another layer of intention here: by fermenting coffee in a low-oxygen environment before washing away the fruit, producers can amplify aromatic complexity while preserving the clean cup structure washed processing is known for. Onyx Coffee Lab has built a reputation for sourcing precisely this kind of considered, high-craft lot — where varietal character and processing technique are chosen to reinforce one another. The single floral note offered here is best understood as an entry point; tracing where that quality lands on the flavor wheel is part of the pleasure.
