The olive tree has its roots buried deep in human history since 6000 B.C. Olive cultivation originated near the Levantine Sea. This area is now Israel, Turkey, and Syria. Many different cultivars of olive have emerged throughout history. Today, olive groves are abundant in the Mediterranean, California, and Australia. Spain is the top producer of olive oil worldwide. Italy is the second largest producer of oil olive. Greece contributes only 10% around the world.
