Olive branches with green olives

Olive branches laden with green olives, symbol of Mediterranean culture and foundation of olive oil production.

About this subject

The olive tree (Olea europaea) is one of the oldest cultivated trees in human history, with records dating back over 6,000 years in the Mediterranean region. Its fruits, olives, are enjoyed both fresh and processed, forming the basis for olive oil production, a cornerstone of the Mediterranean diet.

Olive trees grow slowly and have an impressive lifespan, often living for centuries. Some specimens in the Mediterranean are over 2,000 years old. They adapt well to poor soils and dry climates, but require mild winters and hot summers to bear fruit. Green olives are harvested while still immature, before they darken to the typical ripe color. They have a more bitter flavor and firm texture, commonly used for brined preserves or for producing fruity and spicy olive oils.

Global olive production exceeds 20 million tons annually, led by Spain, Italy, Greece, and Turkey. In Brazil, olive cultivation has been expanding in mild climate regions such as Serra da Mantiqueira and the southern states, aiming to produce high-quality oils. Olives are rich in monounsaturated fats and antioxidants like vitamin E, associated with cardiovascular benefits. In Mediterranean culture, the olive branch symbolizes peace, wisdom, and prosperity, appearing in mythologies and religious traditions.
