Processing must take place to remove the coffee beans from the cherries. There are two types of methods used; wet process and dry process. The wet process starts with a machine which removes the skin and most of the pulp. The product is then placed in fermentation tanks then dried. Finally a machine removes the remaining parchment and silver skin to expose the green coffee bean.
