Green coffee beans are raw and unroasted dried coffee beans that are inside the coffea fruits that are found on the coffee plant, be they Arabica, Robusta, Liberica or Excelsa coffee beans.

It is because of the chlorogenic acid content that green coffee beans are believed to be healthier than roasted beans and have beneficial health benefits.
