Once cherries are received, they are hand-picked and floated to ensure only those of the best quality continue to the processing stage. These cherries are placed into a deep-cleaned fermentation tank, which is hermetically sealed. Fresh cool water is then poured on top of the sealed coffee. The seal created by the water pressing onto the sheeting creates a vacuum effect on the coffee below, creating an anoxic environment for fermentation to begin, which lasts for between 48 and 72 hours. The water and sheet act as not only a sealant but a heat exchange, allowing the heat build-up to transfer to the water, which evaporates away. A stabilised temperature of around 25 degrees Celsius ensures the cherry doesn’t over-ferment. This temperature is regularly monitored, and if it falls too low for fermentation to continue, hot water is added to the water pillow, to provide warmth to the fermenting coffee underneath. Once the fermentation is complete, the water is drained, and the sheet is removed. The now-fermented coffee is rinsed and drained of all residual liquid. The coffee is then sun-dried on raised beds for between 25 and 30 days.
