The Process

This lot is fully washed, whereby ripe cherries are harvested by hand, then floated and hand sorted to select the highest quality for processing. These cherries are then mechanically de-pulped and fermented for 12-18 hours (typically overnight) to break down the remaining mucilage. After fermentation, the wet parchment is washed by high pressured water and grading is done throughout long channels to separate coffee by density. 

Next, the beans are dried on so-called raised African beds for 14-21 days depending on the climatic conditions. The parchment coffee is hand picked and turned throughout to remove defects and ensure consistent drying process, as well as covered at night or during rain to protect against moisture damage. A dedicated quality controller tests the relative humidity daily until an optimum content of 12% is reached, after which the coffee is rested in parchment pending secondary processing prior to export.
