Robusta Parchment or Parchment Coffee is prepared by a series of process like pulping, demucilaging and washing, and drying under the sun. After harvesting, the beans will be extracted by using either the dry or the wet method. The wet method is expensive when compared to the dry method, but the coffee it produces has better quality properties. Robusta adds depth of flavor to an arabica/robusta blend, and a nice crema to espresso blends.
