Olive branches with green olives

Olive branches with green olives depict the ancient tradition of Mediterranean cultivation, essential for table olives and olive oil production.

About this subject

Olive cultivation dates back thousands of years in the Mediterranean region, especially in countries like Greece, Italy, Spain, and Portugal. Green olives are harvested before full ripening, when they still have a green color and firm texture. They undergo a curing process to remove the natural bitterness caused by oleuropein. There are many varieties, such as Spanish Manzanilla and Gordal, each with specific flavor and texture characteristics. The olive tree (Olea europaea) is drought-resistant, adapted to poor soils and temperate climates. Beyond food use, extra virgin olive oil is rich in monounsaturated fats and antioxidants, a cornerstone of the Mediterranean diet. Interestingly, olive trees can live for centuries, with some specimens in the Mediterranean region over a thousand years old. Global olive production exceeds 20 million tons annually, with Spain leading as the largest producer. The olive branch also carries strong symbolism: it appears on the UN flag and in various religious traditions, representing peace and renewal.
