Over 20 types of pepper are known today, although not all of them are "true" pepper, with the botanical name "Piper nigrum". Although this actually means “black pepper”, it is actually the plant whose berries are responsible for green, white and black pepper. For black pepper, the unripe berries of the pepper plant are harvested by hand while still green. It is then dried by the sun for at least a week, making the corns turn brown-black and hard. Its taste is aromatically hot and very spicy.
