The essential oil is distilled from the berries (also known as peppercorns). Harvesting these berries is not easy, as Pink Pepper trees grow to approximately 15 m tall. Harvesters usually climb the tree to pick the peppercorns or knock them with a stick to later collect from the ground. The berries are cleaned by removing the twigs and leaves, then put into a crusher before distillation. The whole process takes place within 24 hours to preserve as much of the essential oil as possible.
