How White Pepper is Produced
Like black pepper, white pepper comes from the dried fruit of the pepper plant, piper nigrum.
With white pepper, the dark outer skin of the pepper fruit is removed by soaking before the seed is dried. 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 give black pepper its aroma. As a result, white pepper has a different flavor and heat component than black pepper.
