Coffea Liberica is a coffee plant that grow at lowlands and specifically on peatlands. Unlike Arabica and Robusta, Liberica coffee is large and able to grow up to 9 meters in height. Tea as a refreshing drink made from coffee skin which called cascara tea, had been developed in Indonesia and around the world. However, tea that made from green coffee skin is rarely been produced.
