At the mill in Chiclayo, Peru, these black bags contain parchment coffee (coffee beans that have been processed and dried, but are still encased inside the parchment envelope, the endocarp). Warehousing coffee this way keeps it fresher until it is ready for export. Once sold, these beans will be sent to the mill to be hulled, polished, graded and sorted. Once milled, coffee beans are referred to as ‘green coffee’ and are ready to be shipped to the importing country’s roaster.
