The short answer: Extra virgin olive oil (EVOO) is the highest quality olive oil, made from pure cold-pressed olives, with no chemicals or heat, and it has a superior taste and more health benefits. Pure olive oil, on the other hand, is a blend of refined olive oil and a small amount of virgin olive oil, making it more heat-stable and neutral in flavor, but with fewer antioxidants. The choice depends on your cooking needs: use EVOO for dressings and low-heat cooking, and pure for high-heat frying.
Olive oil is extracted from the fruit of olive trees. The difference between extra virgin and pure lies in how the oil is extracted and processed.
Extra virgin olive oil is obtained from the first cold pressing of olives, using only mechanical means. No heat or chemicals are used, which preserves the natural flavors, aromas, and nutrients. To be labeled extra virgin, the oil must meet strict standards for acidity (less than 0.8%) and sensory quality (no defects).
Pure olive oil, which is often labeled simply as ‘olive oil’ or ‘pure olive oil’, is a blend of refined olive oil and a small percentage (usually 5-10%) of extra virgin or virgin olive oil to add flavor. The refining process involves heat and chemical solvents to remove off-flavors and reduce acidity, resulting in a more neutral oil with a higher smoke point.
This production difference directly affects taste, nutrition, and cooking performance.
If you care about taste, the difference is night and day.
Extra virgin olive oil is a vibrant, flavorful oil. Depending on the olive variety and region, it can be peppery, grassy, fruity, or nutty. It adds a distinct character to dishes. When you drizzle it over a salad or use it as a finishing oil, you taste the complexity.
Pure olive oil is bland in comparison. It has a neutral flavor and a very subtle hint of olive. This makes it a good choice for cooking when you don’t want the oil to overpower the dish, but you lose the delicious taste that EVOO brings.
For those who love the taste of olives, EVOO is the clear winner.
The health benefits of olive oil are well known, but they vary between the two types.
Extra virgin olive oil is rich in monounsaturated fats (especially oleic acid) and polyphenols, which are powerful antioxidants that reduce inflammation and protect against heart disease. The processing preserves these compounds, making EVOO the healthiest choice.
Pure olive oil loses many of these beneficial compounds during refining. The heat and chemicals strip away antioxidants, so it has a lower polyphenol content. While it still contains healthy fats, you miss out on the extra benefits.
If you are using olive oil for its health properties, always choose extra virgin.
Smoke point is the temperature at which an oil starts to smoke and break down, producing harmful compounds and off-flavors.
Extra virgin olive oil has a moderate smoke point of about 375°F (190°C). This makes it suitable for sautéing, roasting, and baking at medium temperatures. However, frying at high temperatures can damage it and reduce its health benefits.
Pure olive oil has a higher smoke point, around 420°F (215°C) or higher, because it has been refined and has fewer impurities. This makes it better for high-heat frying and searing.
For everyday cooking where heat is moderate, EVOO works fine. For deep frying or very high heat, pure olive oil is a better choice to avoid burning.
Price is another factor to consider.
Extra virgin olive oil is more expensive because the production is labor-intensive and yields lower quantities. You are paying for quality and flavor.
Pure olive oil is cheaper because it uses refining processes that are more efficient. If you are on a budget and need a versatile oil for cooking, pure olive oil may be more economical.
When it comes to shelf life, EVOO has a shorter shelf life of about 12-24 months, while pure olive oil can last longer due to refining. However, both should be stored in a cool, dark place to prevent oxidation.
Now that you know the differences, here is a practical guide to help you decide.
If you primarily use olive oil for:
Ideally, you might keep both in your pantry: EVOO for dressings and finishing, and pure for frying.
When shopping for olive oil, always check the label. Look for terms like ‘extra virgin’ or ‘virgin’ for the best quality. Also, consider the harvest date rather than the best-by date, and try to buy from reputable brands. For more detailed recommendations, you can check out our best olive oil buying guide.
Proper storage is critical for maintaining the quality of any olive oil, but it matters even more for extra virgin varieties because their delicate flavors and antioxidants are easily degraded. Light, heat, and oxygen are the three main enemies of olive oil. Exposure to light accelerates oxidation, which turns the oil rancid and destroys polyphenols. Heat speeds up chemical reactions that break down the oil’s structure. Oxygen reacts with the oil’s fatty acids, leading to off-flavors and a shorter shelf life.
To protect your oil, always choose dark glass bottles or tins. Clear bottles may look attractive, but they allow light to penetrate and damage the oil. If you buy oil in a clear bottle, transfer it to a dark glass container or store it in a dark cabinet. Keep the oil away from heat sources like the stove, oven, or direct sunlight. A cool pantry is ideal, but refrigeration is not recommended because condensation can introduce moisture, and the cold can cause the oil to solidify, making it hard to pour. However, if you live in a very hot climate, storing oil in the refrigerator is better than letting it overheat. Just allow it to come to room temperature before use.
Oxygen is another concern. Every time you open the bottle, oxygen enters. To minimize exposure, buy smaller bottles that you will use within a few months rather than large containers that sit half-empty for a year. If you must buy in bulk, transfer a portion to a smaller bottle for daily use and keep the rest sealed in a cool, dark place. Some people use wine preservers or vacuum pumps to remove oxygen from the bottle, but simply using the oil regularly and keeping it tightly capped is usually sufficient.
Finally, pay attention to the harvest date. Unlike wine, olive oil does not improve with age. It is best consumed within 18 to 24 months of harvest, and ideally within a year for peak flavor and health benefits. The best-by date on the bottle is often two years after bottling, but the harvest date is a more reliable indicator of freshness. If the oil tastes stale, musty, or like crayons, it has likely gone rancid and should be discarded.
Even savvy shoppers can fall into traps when selecting and using olive oil. Being aware of these common mistakes can help you get the best value and performance from your purchase.
Mistake 1: Assuming ‘light’ olive oil is lower in calories. Light olive oil refers to the oil’s flavor and color, not its calorie content. It is a refined oil with a neutral taste, but it has the same number of calories as any other olive oil. If you are watching your weight, measure your portions regardless of the type.
Mistake 2: Using extra virgin olive oil for deep frying. While EVOO can handle moderate heat, its smoke point is lower than that of pure olive oil. Deep frying at high temperatures will not only damage the oil’s beneficial compounds but also impart off-flavors. For deep frying, choose pure olive oil or a high-oleic oil like avocado oil.
Mistake 3: Buying olive oil based on country of origin alone. Many brands blend oils from multiple countries. While certain regions are famous for high-quality olive oil, a blend can be perfectly fine, especially for everyday cooking. What matters more is the harvest date, the acidity level, and whether the oil is extra virgin. Look for a harvest date and a clear label indicating the type.
Mistake 4: Storing oil near the stove. The heat from cooking can quickly degrade the oil. Keep your oil in a cool, dark cabinet away from the stove and other heat sources.
Mistake 5: Ignoring the taste. If you are buying extra virgin olive oil, taste it. A good EVOO should have a fresh, fruity aroma and a peppery finish. If it tastes flat or greasy, it may be old or of poor quality. Many specialty stores offer tastings, and some brands provide detailed flavor notes.
Mistake 6: Using olive oil for everything. Olive oil is versatile, but it is not the best choice for every cuisine. For example, toasted sesame oil is better for Asian dishes, and neutral oils like canola or grapeseed are preferable for baking where you don’t want an olive flavor. Use olive oil where its flavor enhances the dish.
By avoiding these pitfalls, you can make more informed choices and enjoy better results in the kitchen.
While olive oil is a staple in many kitchens, there are situations where another oil might be a better fit. Understanding the alternatives can help you decide when to branch out.
Avocado oil: With a very high smoke point (often above 500°F), avocado oil is excellent for high-heat cooking like searing and frying. It has a mild, slightly nutty flavor and is rich in monounsaturated fats. However, it is typically more expensive than olive oil and may be harder to find.
Canola oil: This is a budget-friendly, neutral-flavored oil with a high smoke point. It is low in saturated fat and contains omega-3 fatty acids. It is a good all-purpose oil for baking and frying, but it lacks the flavor and antioxidants of extra virgin olive oil.
Coconut oil: With a medium smoke point, coconut oil is popular for baking and sautéing. It adds a distinct coconut flavor, which may or may not suit your dish. It is high in saturated fat, so use it in moderation if you are watching your cholesterol.
Sesame oil: Toasted sesame oil is a flavoring oil, not a cooking oil. It is used in small amounts to add a nutty, Asian-inspired taste to dishes. It should not be used for frying because it burns easily.
Grapeseed oil: This oil has a high smoke point and a very neutral flavor, making it ideal for frying and baking. It is a good source of vitamin E but is often more expensive than canola.
When should you not buy olive oil? If you are looking for a completely neutral oil for baking delicate cakes or for high-heat frying where cost is a concern, other oils may be more practical. Also, if you dislike the taste of olives, you may prefer a neutral oil. However, for dressings, marinades, and moderate-heat cooking, olive oil, especially extra virgin, remains a top choice for flavor and health.
Yes, you can substitute, but be aware of the flavor difference. EVOO will add a stronger taste and may lower the smoke point. For high-heat frying, pure olive oil is safer. For dressings, EVOO is better.
No, pure olive oil is not fake, but it is refined, which means it has fewer nutrients and less flavor. It is still a healthy oil, but extra virgin has more antioxidants.
Both oils are calorie-dense, so they should be used in moderation. Extra virgin olive oil may support weight loss better due to its anti-inflammatory properties, but the key is to not overuse any oil.
