History and Origins of Extra Virgin Olive Oil

The use of olive oil dates back to ancient times. Its history is intertwined with that of ancient Greece and Rome, where extra virgin olive oil was considered a gift from the gods. Olive trees were cultivated for centuries, and oil was an essential element in the Mediterranean diet.

Originally from the regions of the eastern Mediterranean, this oil found fertile ground in the sun-drenched lands of the Mediterranean basin, especially in Italy, Greece, Spain, and Turkey. The first olive trees were cultivated as early as 6000 BC, and the method of oil extraction remained largely unchanged until the advent of modern technology.

Over the centuries, extra virgin olive oil has not only been a food but also a precious element in various aspects of daily life. It has been used as medicine, in religious rituals, as fuel for lamps, and even in cosmetics. Its importance was such that in some cultures, it was considered a symbol of peace and purity, used in the anointing rituals of kings and priests.

In modern production, the extraction process remains faithful to tradition, emphasizing the quality and purity of the product. Olives are handpicked to avoid damage to the fruits and are cold-pressed within a few hours of harvesting to ensure that the oil retains all its sensory and nutritional qualities. The classification as “extra virgin” is reserved for oils that meet rigorous standards of acidity and absence of sensory defects.

Extra virgin olive oil is not only a vital component of Mediterranean cuisine but also an element of a cultural heritage that continues to influence dietary habits and healthy lifestyles globally.

Its history, production method, and health benefits make it a true elixir of long life.

How Extra Virgin Olive Oil is Produced

The production of extra virgin olive oil is an ancient art that combines tradition and technological innovation to create a high-quality product. Here are the main phases of the production process:

  1. Olive Harvesting: The olive harvest, known as “harvesting,” is the first critical step in the production of extra virgin olive oil. This phase must be carefully planned as the timing of the harvest significantly affects the quality of the oil. Olives are harvested when the oil content in the fruits is at its maximum and before fermentation begins, which can degrade quality. Harvesting usually takes place between October and December, depending on the variety of olives and climatic conditions.
  2. Crushing: Once harvested, the olives are transported to the mill to be processed as quickly as possible, ideally within 24 hours of harvesting. The olives are first separated from the leaves and washed to remove impurities. Subsequently, the crushing process begins, which can be done through traditional methods such as stone mills or more modern methods such as mechanical crushers. This process breaks down the olive tissues to facilitate the release of oil.
  3. Malaxation: After crushing, the obtained olive paste is slowly mixed in a process called malaxation. This step is essential to allow the small oil droplets to aggregate and separate more easily from the aqueous phase and solids during the subsequent extraction. Malaxation lasts from 20 to 40 minutes and must be carried out at a controlled temperature to preserve the sensory properties of the oil.
  4. Extraction: This is followed by extraction, which can be carried out by centrifugation, pressing, or percolation. The most common method today is centrifugation, which separates the oil from the rest of the olive paste without the use of solvents, thus maintaining the integrity and purity of the oil. This process ensures that the oil is of the “extra virgin” category, with low acidity and no sensory defects.
  5. Decantation and Filtration: The extracted oil still contains a certain amount of moisture and solid residues. It can be left to naturally settle in large tanks to separate these residues or can be filtered. Filtration makes the oil clearer and more stable over time, reducing the risk of fermentation and extending its shelf life.
  6. Bottling: Finally, the oil is bottled in containers that do not react with the oil, typically dark glass bottles, stainless steel, or ceramic containers. These materials protect the oil from light and oxidation, preserving its quality until consumption.

Each phase of the production process of extra virgin olive oil is crucial to ensure that the final oil is of high quality, preserving all its aromas, flavors, and nutritional properties.

Different Types and Grades of Extra Virgin Olive Oil

Extra virgin olive oil can vary greatly in terms of taste, aroma, and color, depending on the variety of olives used, the soil in which they grew, and the production method. Let’s examine the different types and grades of extra virgin olive oil to help you choose the one that best suits your tastes and culinary needs.

  1. Fruity Extra Virgin Olive Oil: This type of oil is known for its aroma reminiscent of fresh olives. The degree of fruitiness can vary from light to intense. A light fruity oil is more delicate and pairs well with dishes that require a less dominant flavor, such as steamed fish or light salads. An intense fruity oil, on the other hand, has a stronger flavor and can be used to dress robust salads, grilled meat, or to make bruschetta.
  2. Bitter Extra Virgin Olive Oil: The bitter taste is a desirable characteristic in high-quality extra virgin oils, often perceived alongside sensations of freshness and cleanliness in the mouth. This type of oil pairs well with rich foods and intense flavors such as legumes or grilled vegetables.
  3. Spicy Extra Virgin Olive Oil: A spicy aftertaste is another sign of high-quality oil. This hint of spiciness is particularly appreciated by connoisseurs because it adds a level of complexity to the oil’s flavor. It is ideal for dishes that require some additional character, such as hearty soups or red meats.
  4. Sweet Extra Virgin Olive Oil: Oils with a sweeter flavor profile are less common and tend to be very delicate and less bitter. These oils are excellent for desserts, fresh fruit, or as a finishing touch on dishes that require a hint of sweetness without overpowering the other ingredients.
  5. Balanced Extra Virgin Olive Oil: A balanced oil offers good harmony between fruity, bitter, and spicy notes, with none of the sensations dominating the others. This makes the oil extremely versatile, suitable for a variety of dishes, from simple salads to more complex dishes.

The characteristics of each extra virgin olive oil can also vary significantly depending on the production region.

For example, oils from Tuscany are often robust and slightly spicy, those from Puglia can be fruity and dense, while oils from Sicily often have a balance between sweetness and acidity.

Each type of extra virgin olive oil offers a unique palette of flavors and aromas that can greatly enrich the culinary experience. Experimenting with different types will allow you to discover which oil best suits your favorite dishes.

How to Choose Extra Virgin Olive Oil

  1. Read the Label: Always check the label for information on origin, olive variety, and expiration date. A quality oil should indicate the production area and preferably the variety of olives used.
  2. Look at the Harvest Date: Fresh oil is always preferable. Look for the harvest date; oil should not be kept on sale for more than 18-24 months from the harvest date.
  3. Certifications: Check for quality certifications and protected designations (DOP, IGP), which guarantee compliance with high production standards and the authenticity of the origin.
  4. Color: The color can range from green to golden, but it is not a reliable indicator of quality as it can be easily altered. Focus more on flavor and aroma.
  5. Choose an Adequate Container: Prefer oils contained in dark glass bottles or stainless steel containers that protect the oil from light.

How to Store Extra Virgin Olive Oil

  1. Keep Away from Light and Heat: Store the oil in a cool, dark place, away from heat sources such as the oven or stove. Light and heat accelerate the oxidation of the oil, degrading its flavor and properties.
  2. Use Appropriate Containers: Keep the oil in dark glass, ceramic, or stainless steel containers. Avoid plastic containers that can interact with the oil and alter its taste.
  3. Seal the Container Well: Make sure the oil container is always tightly closed. Exposure to air can increase oxidation and lead to oil rancidity.
  4. Consume Appropriately: Once opened, try to use the oil within a few months. Although the oil can remain good for up to two years, it is best to consume it within six months of opening to enjoy all its flavors and nutritional benefits.

By following these tips, you can enjoy the optimal qualities of your extra virgin olive oil and use it to enhance your favorite dishes with its unique flavor and health benefits.
