Giling Basah Processing

After harvesting the coffee trees small-holder farmers deliver the cherries to the collectors. Collectors usually have pulping facilities but sometimes also grow coffee themselves. At the collection stations the outside skin is mechanically removed through pulping. The pulp is used as natural compost for the coffee trees. The cherry, now called ‘parchment’ is then being washed. This must be done to remove a coating from the parchment called mucilage that speeds up fermentation for the bean. This process is referred to as ‘Semi- Washing’ or ’Giling Basah’ in Bahasa, Indonesian language. Overnight the Semi-Washed coffee is held in containers without water to allow some additional fermentation. Next day the parchment will be washed again to remove the remaining mucilage and stop the fermentation process. The parchment is then dried on patios to have 18%-20% moisture content. The hulled parchment now called ‘Labu’ still has a high humidity before it has reached the ‘green bean’ phase of processing. Next is drying the Labu down to a moisture content of 15% which now becomes ‘Asalan’. Then collectors take and bring the Asalan to PT. Sumatera Jaya Kopi’s warehouse in Takengon. At our processing unit the Asalan is placed back in the sun for second drying down to export ready moisture content of around 12%-13%. The Asalan green beans is now brought to the gravitation machine called ‘Sutton’ to seperate and remove dust, stones, black and broken beans and other foreign material. Following the Asalan is delivered to the hand-picking room to manually remove black, brown and broken beans and other foreign material. The coffee will be hand-picked a second time (“double picked”) until the ‘ready for export’ standard with a maximum of 11 defects is achieved. The green beans end up in 60kg bags which are marked for export to specific customers and are transported to our warehouse in Medan. Here the container will be stuffed and sealed having an independent surveyor and our own staff on site. The loaded container will be send through our forwarder to the port in Belawan for worldwide shipping. Operational support along the supply-chain is organized from our office in Medan.
