Where does olive oil come from?
Olive oil has a very ancient history. As proof, the olive tree is the first tree mentioned in the Bible.
This oil is so famous that we owe the etymology of oils to it. Indeed, the term “Olea”, designating oil in general, originates from the word “olive” (the fruit). As for the geographical roots of the olive tree, botanists are not unanimous. Some think it originated in Asia after passing through Egypt, to finally conquer the entire Mediterranean region.
Be that as it may, the olive tree has since been successfully introduced into regions with the same type of climate: Southern California, South Africa, Australia, Mexico, Brazil and even Japan.
