But how can we get rid of them? Or cut to a minimum the chances of getting a bad bean into so much goodness?
Some cooperatives in Rwanda are adopting this unique practice of hand-sorting wet parchment after being washed and fermented.
Some defective beans can be visually detected more easily when the parchment is slightly transparent with moisture. It is another opportunity to eliminate immature green beans, floaters, quakers, beans with anthracnose and insect-damaged (Antestia Bug) coffee that can result in the awful "potato taste defect".
Also, the slow introduction of air before the sun in the drying process, helps to keep the parchment intact and without cracks. If we think that the parchment is a small protective layer that reduce the shock of too much heat in the bean, this initial drying phase in raised beds and under shade, promotes that these internal molecular changes happen slowly and progressively.
