Olive Oil (Olio d’Oliva)

Italian folk legends maintain that the ideal habitat for an olive tree has five true characteristics: sun, stone, drought, silence and solitude. It is no wonder that olive oil has achieved such a special place in the collective Mediterranean heart. This special oil has distinct properties, both nutritional and salutary. According to La Cucina Italian, olive oil is the most digestible edible fat. Other beneficial characteristics include increasing the assimilation of vitamins A, D, and K in the human body; slowing the human aging process; aiding the functions of vital organs; and providing our bodies with essential acids.
Ancient Romans were known to infuse olive oil with flowers and herbs to create medicines and cosmetics. Homer referred to olive oil as “liquid gold.” Perhaps the ancient Greeks also thought of the oil as akin to gold – athletes were known to rub themselves down with it before competition, which gave them a magical glow. Crowns built from the leaves of olive trees were donned by the best athletes and the bravest war heroes.

History of Olive Oil

Fossil remains of an ancient tree, dating back some 20 million years, were discovered near Livorno, Italy. This ancient tree is an ancestor of today’s olive trees and was not used for cultivation. Olives were first cultivated in the “fertile crescent,” an eastern Mediterranean region. Until about 1500 BC, Greece was the most heavily cultivated area, but olives were quickly making their spread throughout the Mediterranean. Olives reached southern Italy in the 8th century BC due to the expansion of Greek colonies. By the time of the Roman Empire, olive trees dotted the entire Mediterranean basin. Since then, olive oil has become a symbol of pride to Italians, and Italy is now the most prolific producer of olive oil in the world.
The leading production regions in Italy are Liguria, Tuscany, Umbria, and Puglia. In fact, Puglia is home to one-third of Italy’s olive trees. Piedmont and Val D’Aosta are the only Italian regions that do not produce olive oil. Italian extra virgin olive oil is in a class of its own. Chefs around the world find no match for its use in cooking and as a condiment in countless dishes, from soups and salads to seafood and meats. Each olive oil, produced from specific varieties of olive, has distinguishable characteristics due to terrain, climatic differences, and methods of harvesting. Today, Italy has 30+ DOP certified olive oils, and one IGP oil.
