Origin and Processing

This coffee comes from Sabanilla de Alajuela, in Costa Rica’s Central Valley, a region known for precise micromill processing, natural and honey methods, and highly expressive cup profiles.

The San Isidro 39 variety provides a fascinating base for more intense processing, especially when handled as a controlled natural. The Black Diamond Natural process is designed to develop a deeper, fruitier, and more complex cup, with elegant fermentation and a particularly juicy texture.

The result is a coffee with real energy in the cup: red fruit, sweetness, lively acidity, and a subtle lactic impression reminiscent of strawberry yoghurt. It is modern, expressive, and clearly different from more traditional coffees.
