The common varieties of whole olives are:

  • Spanish green olive, in pickled form
  • Green black olive in raw form
  • California olives, which are ripened with oxidation and then pickled

Olives are bitter and therefore cannot be eaten fresh. They are fermented, which reduces the bitter compound present in them.
