The world's most popular spice, Pepper is a berry grown in grapelike clusters on the pepper plant (a climbing vine native to India and Indonesia). The pepper berry is processed to produce three basic types: black, white, and green. Black is the most common. The berry is picked when not quite ripe, then dried until it shrivels and the skin turns dark brown to black. Black is the strongest (slightly hot with a hint of sweetness) flavor of the three.
