Note
Peppers have been sort after since 327 BC during the period of Alexander the Great for seasoning food. The black peppers are produced by picking the green fruit which is then dried and grounded. 

In white pepper production the fruit is allowed to ripen on the vine and the seeds are removed from the fleshy outer layer before being ground.
