Whole White Pepper / Ground White Pepper PowderOrganic White Pepper White Pepper Powder White pepper (Piper nigrum), like black pepper, is made from the berries of the pepper plant, also known as the Piper nigrum. Unlike black pepper, however, white pepper comes from berries that are picked at full ripeness. These berries are then soaked in water to ferment. Finally, the outer layer is removed leaving only the inner seed. As a result, white pepper tends to be more mild than black pepper.
