Olive Oil Frequently Asked Questions

What is Extra Virgin Olive Oil?

Extra virgin olive oil (EVOO) is a type of edible oil derived from the pressing of olives, the fruit of the olive tree (Olea europaea). Renowned for its exceptional quality and health benefits, EVOO is widely regarded as one of the healthiest oils available.

What distinguishes extra virgin olive oil from other types of olive oil is its method of extraction and its chemical composition. EVOO is extracted solely by mechanical means, such as pressing or centrifugation, without the use of heat or chemicals. This gentle extraction process preserves the oil’s natural flavors, aromas, and nutritional qualities, making it the highest grade of olive oil available.

The term “extra virgin” refers to the oil meeting specific quality criteria established by international standards organizations, such as the acidity level (expressed as free fatty acid content) and sensory attributes like taste and aroma. To qualify as extra virgin, the oil must have an acidity level of less than 0.8%, exhibit superior taste characteristics, and be free from defects. At D’Olivo our Ultra-Premium oils must meet over 54 parameters to qualify, which ensures our customers get only the highest quality olive oil available.

How is Extra Virgin Olive Oil Made?

Extra virgin olive oil is made through a meticulous process that begins with harvesting ripe olives from olive trees. Once harvested, the olives are cleaned to remove any debris or leaves. Next, they undergo pressing or centrifugation to extract the oil from the fruit. Importantly, this extraction process must be done solely by mechanical means, without the use of heat or chemicals, to qualify as extra virgin olive oil. The resulting oil is then filtered to remove any remaining solids or impurities. Finally, the oil is stored in stainless steel containers or dark glass bottles to protect it from light and air, which can degrade its quality. This careful process preserves the oil’s natural flavors, aromas, and nutritional properties, resulting in the high-quality product known as extra virgin olive oil.

What Are the Health Benefits of Extra Virgin Olive Oil?

Extra virgin olive oil (EVOO) offers a plethora of health benefits due to its rich nutritional profile. High in monounsaturated fats and antioxidants like polyphenols and vitamin E, EVOO is renowned for promoting heart health by reducing LDL cholesterol levels and lowering blood pressure. Its anti-inflammatory properties help combat chronic inflammation, potentially reducing the risk of conditions such as cardiovascular disease, arthritis, and certain cancers. EVOO also supports brain health, as its antioxidants may protect against cognitive decline and improve memory function. Additionally, its high smoke point makes it suitable for cooking at high temperatures without compromising its nutritional integrity. Incorporating extra virgin olive oil into the diet as a replacement for saturated fats can contribute to overall well-being and longevity, making it a cornerstone of the Mediterranean diet and a staple in healthy eating worldwide.

What is the Difference Between Extra Virgin Olive Oil and Regular Olive Oil?

The main difference between extra virgin olive oil (EVOO) and regular olive oil lies in their quality, flavor, and production methods. EVOO is the highest grade of olive oil, extracted solely by mechanical means, without heat or chemicals. It undergoes stringent testing to ensure it meets specific quality standards, including low acidity levels and superior taste characteristics. EVOO retains the natural flavors, aromas, and nutrients of the olives, making it rich in antioxidants and beneficial fatty acids. In contrast, regular olive oil, often labeled as “pure” or “light,” undergoes a refining process, which involves heat and/or chemical solvents to extract the oil. This process removes impurities but also strips away some of the oil’s flavor and nutrients. Regular olive oil typically has a milder taste and lower nutritional value compared to extra virgin olive oil.

How Should You Store Extra Virgin Olive Oil?

To maintain the quality and freshness of extra virgin olive oil, proper storage is a must. We recommend that you store your oil in a cool, dark place away from direct light and heat sources, such as sunlight, stovetops, or ovens, which can cause oxidation and deterioration of the oil’s flavor and nutritional content. Choose opaque or dark glass bottles to shield the oil from light exposure, as clear containers can accelerate spoilage. Additionally, tightly seal the bottle after each use to minimize air exposure and oxidation. Once opened, be sure to use up your oil in a timely manner to avoid the chance it goes rancid. If it’s been awhile since your last usage, be sure to taste your oil before using it to ensure it’s still fresh.

How Can I Use Olive Oil?

The beauty of olive oil is that it is extremely versatile and can be used in a number of ways and dishes to enhance the overall flavor profile. Use olive oil as a dressing or drizzle over salads, vegetables, or cooked dishes for a burst of richness. It serves as an excellent base for marinades, infusing meats, poultry, or seafood with flavor before grilling, roasting, or sautéing.

Olive oil can also be used as a healthier alternative to butter or margarine in baking recipes, adding moisture and richness to cakes, cookies, and bread. When cooking, use olive oil to sauté or stir-fry vegetables, meats, or grains, adding depth and complexity to your dishes.

Additionally, olive oil can be used for frying at moderate temperatures due to its high smoke point. Whether used as a finishing touch or a cooking staple, olive oil elevates the taste and nutritional value of a wide range of foods.
