Extra virgin olive oil (EVOO) is one of the pillars of the Mediterranean diet and an essential ingredient in Spanish and global cuisine. Its consumption not only adds flavor to dishes but also offers health benefits thanks to its healthy fats, antioxidants, and vitamins. However, not all olive oils are the same, and recognizing a good extra virgin olive oil requires attention to several factors. In this article, we explain how to differentiate a quality oil, the different types available, and the most prominent producing regions.
What does “extra virgin” mean?
Extra virgin olive oil is oil obtained directly from olives using mechanical processes, without undergoing chemical treatments or refining. To be considered extra virgin, the oil must meet certain standards for taste and acidity:
-
Maximum acidity of 0.8%: Measured in free oleic acid, this indicates the purity of the oil and its lack of defects.
-
Taste and aroma: It should have a balanced taste, with no unpleasant bitterness or olfactory defects.
-
Natural processing: It is only obtained through cold pressing or centrifugation, without additives or chemicals.
EVOO is valued for its fruity flavor, fresh aroma, and ability to enhance any dish, from salads to stews and desserts.
How to recognize a good EVOO
Recognizing a good extra virgin olive oil isn’t just about reading the label. Here are some practical tips:
1. Sensory analysis
-
Smell: A good EVOO has a fresh, fruity, and herbal aroma. You may notice notes of green olive, apple, freshly cut grass, or almond.
-
Taste: When tasting it, you should feel a balanced flavor between sweet, bitter, and peppery. The bitterness and pepperiness are positive characteristics, as they indicate the presence of natural antioxidants.
-
Color: While color is not a definitive indicator of quality, green and golden tones typically reflect freshness and a good harvest.
2. Reading labels
-
Denomination of origin: Look for oils with protected designation of origin (PDO), which guarantees their origin and quality.
-
Harvest date: Unlike the bottling date, the harvest date indicates when the olives were picked. A fresh oil is usually more aromatic and healthier.
-
Olive variety: Some varieties, like Picual, Arbequina, or Hojiblanca, offer distinct flavor profiles. Knowing the variety helps you choose based on your culinary preferences.
3. Packaging and storage
-
Dark packaging: EVOO should be stored in dark bottles to protect it from light, which degrades its properties.
-
Temperature: Store it in cool places away from prolonged heat to maintain its freshness and flavor.
-
Producer transparency: Trustworthy brands clearly indicate the origin, variety, and extraction method of the oil.
Types of Olive Oil
-
Extra virgin olive oil (EVOO): The highest quality oil, obtained through mechanical methods, with no flavor defects and a maximum acidity of 0.8%.
-
Virgin olive oil: Also obtained mechanically, but it may have slight sensory defects and a maximum acidity of 2%.
-
Refined olive oil: Obtained from defective virgin oils through chemical processes, losing part of its flavor and healthy properties.
-
Olive oil (blend): Combines refined oil with virgin oil to restore some flavor, but does not reach the quality of extra virgin.
For those seeking flavor and health benefits, EVOO is the recommended choice.
Spain’s Leading Olive Oil-Producing Region
Spain is the largest producer of olive oil in the world, and within the country, Andalusia is the leading region for olive oil production. Provinces like Jaén, Córdoba, Granada, and Seville concentrate the majority of the production, known for their diverse varieties of olives and protected designations of origin.
-
Jaén: Known as the “world capital of olive oil,” it primarily produces Picual variety oil, which is characterized by an intense flavor and slight pepperiness.
-
Córdoba and Granada: Known for varieties like Hojiblanca and Picual, producing oils with fruity and balanced aromas.
-
Seville: Produces Arbequina and other varieties with milder and sweeter flavors.
Andalusia combines tradition, Mediterranean climate, and modern pressing techniques, ensuring high-quality oils that are internationally recognized.

Tunisia: One of the main exporters of extra virgin olive oil globally, though less known among international consumers.
