While they come from the berries of the same plant, the difference between white pepper and black pepper starts when the berriesare picked. To make black pepper, unripe pepper berries are picked and then they are dried, which blackens the skin and adds flavor elements. White pepper is made from fully ripe pepper berries. They are soaked in water for about 10 days, leading to fermentation. Then their skins are removed, which also removes some of the hot piperine compound, as well as volatile oils and compounds that giveblack pepper its aroma. As a result, white pepper has a different flavor and heat component than black pepper. The process used and handling of white pepper can introduce different flavor notes as well.
