Olive trees are among the oldest cultivated trees in history, supporting Mediterranean civilizations for at least 6,000 years. Though it’s speculated that the first wild olive trees were from Syria, it was the Greeks who first cultivated olives. Olive trees have a propensity for warm, subtropical climates, dry rocky limestone soil, and salty sea breezes – all found in abundance along the Greek peninsula and its adjacent islands, such as Crete.

The olive is a drupe, or stone fruit, whose flesh surrounds a pit or stone, inside of which is a seed. Oil makes up as much as 30 percent of the outer flesh, which when pressed turns into olive oil – the juice of the olive fruit. An estimated 90 percent of the world’s olive crop goes to making olive oil. The remainder is harvested for table olives.

Though there are hundreds of olive varieties, most of us know olives as simply green or black. In fact, olives can be black, pink-purple, brown, or green depending on their stage of ripeness when harvested. Green olives are simply unripened olives. If left on the tree, green olives will turn to brown, to vibrant pink-purple, and then to black.

In their natural state, olives are bitter and unpalatable. Thus, before they find their way to your dinner table, olives go through a curing process: brine-cured (in salt water), salt-cured (packed in salt until dry and wrinkly), sun and air-cured, or lye-cured (immersed in a vat of alkaline lye solution, by large commercial olive producers).

According to widely acclaimed Mediterranean food writer, Paula Wolfert, “The texture of a good olive should be firm, not pulpy or mushy, and its flavors should not be overwhelmed with brine or curing. It should neither be too salty nor too bitter. Above all, it should capture and impart the great fresh aroma of its tree.” 

Because the majority of olives are cured in salt or a salt solution, they can be salty upon purchase. But don’t let that turn you off. Simply rinse cured olives under cold tap water and put them in a bowl of water. Cover and let soak overnight. Try one the next day. If it’s still too salty, continue soaking until the excess saltiness has disappeared.

Should have mentioned olives from Israel, they are a Mediterranean Country.
mmoore
You're certainly right! We couldn't get to every Mediterranean country, but Souri, Barnea, Nabali, and Maalot are just a few of the varieties grown in Israel! Malta, Lebanon, and Portugal also grow olives.

Are olive tree's grown in Thailand ?
mmoore
It looks like they could be, but they are more common to the Mediterranean region.

Having recently traveled to Greece, and Crete, I'm missing your mention of Koroneiki olives which are grown primarily on the island of Crete. This olive variety is responsible for some of the most historical and delicious extra virgin olive oil on the planet:)

Syria was the birthplace of the olive. Many of the names are Arabic which is proof enough.

The oldest olive I though came from the middle east Like Lebanon and Syria. I can tell you first hand that the olives from those countries are more superior then any of the European or north African
