Discover what early harvest EVOO is, how it's made, and why it's one of the most valued oils for its quality, flavor, and healthy properties.
What is early harvest EVOO and why is it so highly valued?
Feb 15, 2026
Early harvest EVOO is an extra virgin olive oil produced from olives harvested at their earliest stage of ripeness, when the fruit is still green and has the highest concentration of natural antioxidants. This harvest usually takes place between October and November, depending on the weather conditions of each season.
At this stage, the olive has not yet fully developed its fat content, so the yield is lower. However, this lower production translates into an oil of exceptional quality: more complex, more aromatic, and with a much more powerful sensory profile.
That is why early harvest EVOO is considered one of the most valued oils, both by demanding consumers and by professional chefs and tasters.

How early harvest EVOO is made
Although the process shares phases with the production of any quality extra virgin olive oil, early harvesting introduces additional demands that elevate the final product.
Selection of the optimal ripening point
Producers analyze parameters such as color, texture, and ripeness index to select the exact moment when the green olive offers the maximum phenolic content.
Careful harvesting
Green olives offer greater resistance to detachment. This requires careful harvesting, either by hand or with specialized machinery that prevents knocks or damage to the fruit.
Immediate transport to the oil mill
Minimizing the time between harvesting and milling is key to preventing oxidation. In premium oils, this time rarely exceeds 12–24 hours.
Cold extraction
Milling is always carried out below 27 ºC, which allows the maximum preservation of the volatile compounds responsible for the aroma and polyphenols.
Filtering or decantation
To ensure stability and quality, the oil is filtered or decanted until a clean, bright green EVOO with a rich aromatic profile is obtained.
Why it is such a valued oil
High concentration of polyphenols
Early harvest EVOO has a higher amount of polyphenols than oils obtained from ripe olives. These natural compounds are responsible for:
- Its greater oxidative stability.
- Its powerful aromatic profile.
- Its health benefits.
- Its characteristic balanced bitterness and pungency.
Aromatic intensity
Early harvest EVOO stands out for an aromatic depth difficult to find in later harvest oils: freshly cut grass, tomato plant, green almond or even fruity notes such as banana or apple depending on the variety used.
Limited production
Less oil is obtained from green olives. This low yield explains its higher price and exclusive character.
International recognition
Early harvest EVOOs are the most awarded in national and international competitions thanks to their sensory quality.

Health benefits of early harvest EVOO
Early harvest EVOO is characterized by its richness in natural compounds typical of green olives, especially polyphenols, whose concentration is one of the most valued indicators in high-quality oils.
In the current campaign, our Ad-Morum early harvest EVOO has a concentration of 696 mg/kg of total polyphenols (expressed as caffeic acid), a much higher level than usual in traditional harvest oils. This value reinforces its aromatic intensity, stability, and unique character.
Below, we explain what this data really means from a technical point of view and supported by official studies.
Polyphenols and scientific evidence backed by EFSA
The European Food Safety Authority (EFSA) officially recognizes that:
“Olive oil polyphenols contribute to the protection of blood lipids from oxidative damage”,
provided that the oil provides at least 5 mg of hydroxytyrosol and its derivatives per 20 g of daily consumption.Early harvest EVOOs usually easily exceed this concentration because green olives naturally contain more polyphenols.
Clinical studies and scientific reviews on polyphenol-rich EVOO
Scientific studies do not focus on a specific oil, but on the set of extra virgin oils with a high presence of phenolic compounds. Among them, the following stand out:
-
Systematic review published in Nutrients (2025):
Concludes that extra virgin oils rich in bioactive compounds show greater antioxidant action within the Mediterranean diet, especially for their ability to protect against oxidative stress.

Harvard Health Review (2025):
Observes that EVOOs with higher phenolic content are associated with better cardiovascular indicators within dietary patterns rich in extra virgin olive oil.

These conclusions should not be interpreted as exclusive benefits of a single oil, but as a description of the general behavior of high-quality EVOO, a category in which our early harvest oil fully fits due to its natural concentration of polyphenols.
Ideal uses in cooking
Early harvest EVOO is an oil produced especially to be enjoyed raw, where its aromas and nuances can be fully appreciated.
Some of the best applications:
- Fresh salads.
- Toasts and artisan breads.
- Finishing of already cooked meats and fish.
- Creams and purees where the oil acts as a finishing touch.
- Roasted vegetables.
- Hummus, vegetable pâtés, dips, sauces, and emulsions.

Differences between early harvest EVOO and traditional EVOO
| Characteristic | Early harvest EVOO | Traditional EVOO |
|---|---|---|
| Harvest time | October–November | December–January |
| Olive condition | Green | Ripe |
| Yield | Low | High |
| Color* | Intense green | Yellow or golden |
| Polyphenols | Very high | Medium |
| Aroma | Herbaceous and powerful | Softer and sweeter |
| Price | Premium | Standard |
| Recommended use | Raw and gourmet | All-purpose |
*The change in oil color is a completely natural process that occurs over the months. Some olive varieties, even when harvested early, do not present the intense green characteristic of others, such as the Picual variety. That vibrant tone evolves naturally over time.
EVOOs do not contain any type of coloring: variations in their color are exclusively due to the nature of the olive and its ripening process.
Why early harvest EVOO is so fashionable
Today's consumer increasingly values real quality, differentiated products, and traceability. Early harvest EVOO fully fits this trend:
- It is natural and healthy.
- It is exclusive due to its low production.
- It has great gastronomic recognition.
- It offers a superior sensory experience.
- It is perceived as a premium, authentic, and honest product.
In addition, gastronomic dissemination and the culture of good olive oil have contributed to positioning it as an essential product for those who appreciate quality.
Is early harvest EVOO worth buying?
Yes, especially if you are looking for:
- A healthy oil rich in antioxidants.

Frequently asked questions about early harvest EVOO
-
What differentiates early harvest EVOO from traditional EVOO?
Early harvest EVOO comes from green olives harvested at the beginning of the season, resulting in a fresher, more aromatic oil with a higher natural concentration of polyphenols. Traditional EVOO is obtained from ripe olives, which results in a milder oil with a higher yield per kilo of fruit. -
Why is early harvest EVOO usually more expensive?
Its yield is lower because green olives contain less oil. In addition, they require more careful harvesting and rapid milling. These characteristics, together with its more complex sensory profile, make it a limited and particularly valued product. -
What do the polyphenols in early harvest EVOO provide?
Polyphenols are natural compounds present in the olive that directly influence the freshness, stability, and intensity of the oil. EFSA recognizes that olive oil polyphenols contribute to the protection of blood lipids from oxidative damage, provided that at least 5 mg of hydroxytyrosol and its derivatives are provided per 20 g daily.
Ad-Morum's early harvest EVOO has 696 mg/kg of total polyphenols, an exceptionally high figure that explains its fresh character, natural stability, and aromatic power. -
Is early harvest EVOO healthier than other oils?
Scientific research focuses on EVOO rich in bioactive compounds, not on a particular harvest. A review published in Nutrients (2025) shows that EVOOs with a high phenolic content play a relevant role within dietary patterns associated with better defense against oxidative stress.
In addition, studies compiled by Harvard Health (2025) indicate that EVOOs with higher polyphenol content show better associations with cardiovascular indicators within the Mediterranean diet. -
For which dishes is early harvest EVOO ideal?
Its best use is raw, where its nuances are fully appreciated. It is ideal for salads, artisan bread, vegetables, fish, or for finishing dishes just before serving. -
Is it suitable for cooking or frying?
It can be used for cooking, but it is not the most advisable if you want to preserve all its aromatic power. For frying or prolonged cooking, it is usually recommended to use a traditional harvest EVOO like the 5l we offer in our store. -
Why is early harvest EVOO so green?
The intense green color is due to the high presence of chlorophylls and carotenoids typical of green olives at the beginning of the season. This vibrant color is characteristic of the first months after extraction.
In addition, the color evolves naturally over the weeks: chlorophylls gradually degrade due to light, oxygen, and the natural aging of the oil, so the initial green tone softens towards more yellow or golden nuances without affecting the quality, as long as the oil is stored correctly. -
Do polyphenols remain stable throughout the year?
No. Polyphenols progressively decrease over time. That is why it is important to store EVOO in a cool, dark, and tightly sealed place. Oils with higher initial concentrations, such as early harvest oils, better maintain their qualities throughout the season. -
How can I identify a true early harvest EVOO?
An authentic early harvest EVOO should specify the harvest date, variety, origin of the oil, and the indication "early harvest." The existence of laboratory analyses that support its phenolic content is an added value. At Ad-Morum, we always provide the total polyphenol results to guarantee full transparency. -
Is early harvest EVOO always more bitter or spicy?
Green olives contain more compounds responsible for bitterness and pungency, so they are usually more present than in oils made with ripe olives. Even so, a well-made early harvest EVOO always shows a harmonious balance between freshness, bitterness, and pungency.
