Choosing an olive oil may seem simple until you see acronyms like EVOO , EVOO or simply olive oil on the label.
At first glance they may seem like similar categories, but in reality they correspond to different production processes, quality levels and sensory profiles .
That's why many people ask themselves:
- What is the difference between EVOO and VOO?
- Is extra virgin olive oil the same as olive oil?
- Do their nutritional properties change?
- Why is there such a price difference?
- What do certifications such as organic production or Protected Designation of Origin offer?
Understanding these categories is essential to knowing what we are actually incorporating into our diet.
In this article we clearly explain the difference between extra virgin olive oil (EVOO) , virgin olive oil (VOO) and olive oil (OO) , and why elements such as organic certification or Protected Designation of Origin provide an additional level of guarantee, traceability and quality.
Because choosing well starts with understanding what we read on the label.
What does EVOO mean?

EVOO stands for Extra Virgin Olive Oil , the highest recognized category within olive oil.
It is not a commercial name, but a regulated classification that must meet particularly demanding technical and sensory parameters.
How is extra virgin olive oil obtained?
Extra virgin olive oil is obtained exclusively through physical procedures , without chemical processes and without refining.

In a high-quality EVOO, the process begins in the field and continues with very careful production.
The factors that make the difference are:
- harvest at the optimal moment of ripeness
- careful harvesting to avoid damage to the olives
- Fast transport to preserve freshness and properties
- cold extraction solely by mechanical means
The result is, essentially, natural olive juice .
No additives.
Without chemical transformations.
Only the expression of the fruit and the territory from which it comes.

What differentiates EVOO from other categories?
To be classified as extra virgin , an oil must meet criteria established by the International Olive Council (IOC) , including:
- acidity equal to or less than 0.8%
- total absence of sensory defects
- clean, balanced and expressive aromatic profile
- natural presence of compounds such as polyphenols
These requirements make EVOO the most valued category both for its gastronomic quality and its nutritional value.
Within the EVOO category: organic and with Protected Designation of Origin
Within the extra virgin olive oil category, there are also additional levels of guarantee that provide more control, traceability and consistency with the origin.
Organic extra virgin olive oil
An organic extra virgin olive oil is certified according to specific regulations and is produced following environmentally friendly criteria.
An organic extra virgin olive oil:
- It is grown without synthetic pesticides
- respects the natural cycles of the soil
- better protects biodiversity
- It is supervised by official certification bodies
It's not just about what isn't added, but about how the land that produces the oil is cared for.

Protected Designation of Origin
Protected Designations of Origin (PDOs) applied to olive oil guarantee a direct relationship between the product and its territory.
A PDO certifies:
- specific geographical origin
- authorized varieties
- regulated production methods
- additional quality controls
In Spain there are more than 30 Designations of Origin linked to olive oil, among them the DO Siurana , recognized for its olive-growing tradition and its demanding control standards.
An organic extra virgin olive oil with a Protected Designation of Origin thus provides an additional level of guarantee: technical quality, territorial traceability and consistency with the landscape from which it originates.

What is “olive oil” (OO)?
This is where the greatest confusion usually arises.
When a label simply says olive oil , it is usually a mixture of:
- refined olive oil
- a small proportion of virgin olive oil
What does oil refining involve?
Refining is a technical process that allows the oil to be stabilized and its profile to be homogenized.
During that process:
- Unwanted features are corrected
- intense flavors are neutralized
- Certain technical parameters are adjusted
As a result, some of the natural compounds present in virgin oils are also reduced, such as some antioxidants and aromatic elements.
The result is an oil with a more neutral and uniform profile, intended for a less expressive culinary use.
Difference between EVOO, VOO and olive oil
The best way to understand these categories is to compare them:
EVOO
- obtained solely by physical procedures
- acidity up to 0.8%
- without sensory defects
- balanced and complex flavor
- fully retains its natural compounds
AOV
- obtained solely by physical procedures
- acidity up to 2%
- may have slight imperfections
- simpler aromatic profile
- retains a significant portion of its natural compounds
Olive oil
- mixture of refined and virgin
- more neutral profile
- reduced sensory expressiveness
- lower presence of natural compounds after refining
Which is the best option from a nutritional point of view?
Scientific evidence on the Mediterranean diet and cardiovascular health has been developed mainly around extra virgin olive oil .
One of the most relevant studies in this field is the PREDIMED trial, which specifically analyzed the consumption of EVOO within a Mediterranean diet pattern.
Extra virgin olive oil stands out because:
- It retains its natural polyphenols
- provides vitamin E
- It maintains its lipid profile intact
- It has not been subjected to refining processes
Furthermore, when we talk about an organic EVOO with a Protected Designation of Origin , additional guarantees are added related to the origin, the control of the process and the traceability of the product.

Which olive oil should you choose?
If you are looking for:
- complete nutritional profile
- aromatic complexity
- respect for origin
- traceability guarantee
- consistency with a more sustainable agricultural model
The most interesting category is extra virgin olive oil .
And if that EVOO also has organic certification and Protected Designation of Origin , the level of guarantee is even greater.
In this context, an oil like that of Finca Hostalets 1898 represents a particularly well-maintained profile:
- official ecological certification
- protection of the Siurana Designation of Origin
- Handcrafted with manual harvesting
This places it within the category of premium EVOO with a double guarantee: technical quality and territorial traceability .

Frequently asked questions about EVOO, VOO and olive oil
What is the difference between EVOO and VOO?
The main difference lies in the level of requirements. Extra virgin olive oil (EVOO) cannot have any sensory defects and must have an acidity level of 0.8% or lower, while virgin olive oil (VO) allows for slight imperfections and can reach up to 2% acidity.
Is extra virgin olive oil the same as olive oil?
No. Extra virgin olive oil is natural olive juice obtained solely through mechanical processes. Olive oil , on the other hand, is usually a blend of refined oil with a small proportion of virgin oil.
What does it mean for an extra virgin olive oil to be organic?
This means that it has been produced in accordance with organic farming regulations, without synthetic pesticides and with official controls that certify the process.
What does a Protected Designation of Origin (PDO) bring to olive oil?
A Protected Designation of Origin guarantees geographical origin, regulated production methods, authorized varieties and additional quality controls.
Conclusion
Not all olive oils are the same, even though they may seem so at first glance.
When choosing, it is helpful to be clear about this classification:
- Organic EVOO + Protected Designation of Origin → maximum guarantee of quality, traceability and respect for the environment
- EVOO → highest regulated category within olive oil
- AOV → natural oil, with lower sensory requirements
- AO → refined oil combined with virgin oil, with a more neutral profile
The difference isn't just in the name.
It's in the process, in the care of the fruit, in the respect for the land, and in the real value that the oil brings to your diet.
Choosing with knowledge is choosing with discernment.
