In the world of Olive OIl, Extra Virgin Olive OIl (EVOO) stands on its own as the healthiest olive oil found anywhere. Why is this? Because to be labeled EVOO, the oil has to meet stringent guidelines to be called an EVOO. These guidelines are set forward in the EU, USA and Australia with slight variations between each. An uneducated consumer might be confused, thinking that they are buying EVOO, when, in fact, they are purchasing a lesser quality olive oil. Companies use smart marketing ploys and name their products - “light olive oil”, “100% virgin olive oil”, “extra healthy olive oil”, “cold pressed olive oil”.. A true EVOO must contain these names together - “Extra Virgin Olive Oil”. As we will learn in this blog there are many differences between EVOO and plain olive oil.
Production Methods
The production methods for olive oil and extra virgin olive oil are significantly different, influencing their final quality and characteristics. Olive oil, a general term that encompasses various grades, is often produced using a combination of mechanical and chemical processes. This type of oil typically involves refining, where heat and chemicals are used to extract the oil and remove impurities. The result is a more stable product with a longer shelf life, but one that may lack the nuanced flavors and health benefits found in higher-quality oils.
In contrast, extra virgin olive oil is made using purely mechanical methods, specifically cold pressing. This method involves crushing the olives and extracting the oil without the use of heat or chemicals. To qualify as extra virgin, the oil must meet strict criteria set by regulatory bodies, such as the International Olive Council. These criteria include a low level of free fatty acids (less than 0.8%) and the absence of sensory defects. This meticulous production process ensures that EVOO retains the natural flavors, aromas, and nutrients of the olives.
Quality
The quality of olive oil is often determined by its level of acidity, purity, and the presence of beneficial compounds like polyphenols and antioxidants. Refined olive oils, which may be labeled simply as "olive oil" or "pure olive oil," often lack the high levels of these beneficial compounds due to the refining process. These oils are usually a blend of refined and virgin olive oils, resulting in a product that is more uniform in flavor but less rich in nutrients.
Extra virgin olive oil, on the other hand, is considered the highest quality olive oil available. Because it is unrefined and made from the first cold pressing of the olives, it retains a higher concentration of polyphenols, antioxidants, and vitamins. These compounds not only contribute to the oil’s health benefits but also play a crucial role in its taste and aroma. The stringent standards for EVOO ensure that consumers receive a product that is both pure and of superior quality.
Flavor Profiles
The flavor profiles of olive oil and extra virgin olive oil can vary widely, influenced by factors such as the type of olives used, the region of production, and the harvesting methods. Refined olive oil tends to have a more neutral taste, making it suitable for cooking where the oil's flavor is not intended to dominate the dish. Its mildness can be an advantage in recipes that require a subtle background note rather than a prominent taste.
Extra virgin olive oil is renowned for its complex and robust flavor profile. It can range from fruity and floral to peppery and bitter, often with a distinct freshness that is absent in refined oils. The diversity in taste is a result of the natural variations in olive cultivars, terroir, and production methods. Connoisseurs often seek out specific EVOOs for their unique flavor characteristics, much like fine wines. This complexity makes EVOO an excellent choice for drizzling over salads, finishing dishes, or dipping with bread, where its flavor can be fully appreciated.
Conclusion
In conclusion, while both olive oil and extra virgin olive oil offer culinary and health benefits, their differences in production methods, quality and flavor profile are significant. Extra virgin olive oil shines in applications that allow its complex flavors and healthful properties to be showcased. We hope that Understanding these differences enables you to make informed choices, ensuring you select the right type of olive oil for their specific needs and preferences.
