How to recognize good extra virgin olive oil?
Faced with the hundreds of options available in stores or on the Internet, choosing a good olive oil can seem difficult.
Between marketing claims, different origins, and the many prices displayed, how can you tell if an oil is truly of high quality?
Fortunately, a few criteria help distinguish a genuine extra virgin olive oil from a more ordinary one.
Here are the 8 essential points to observe before buying.
1. Check that it really is extra virgin olive oil
Not all olive oils have the same level of quality.
The extra virgin category corresponds to the highest quality level defined by European regulations.
It meets very strict physico-chemical and sensory criteria and has no defects in taste or odor.

2. Look for a balanced flavor profile
An excellent olive oil should be neither aggressive nor completely neutral.
It expresses a balance between three characteristics:
- fruitiness, which conveys the aromas of fresh olives;
- bitterness, a sign of freshness;
- pungency, that slight tingling sensation characteristic of oils rich in phenolic compounds.
An oil that is completely flat or lacking in character is generally not a sign of high quality.
3. Look at the harvest date
Unlike wine, olive oil does not improve in quality over time.
It is at its best when fresh.
Prioritize producers who clearly indicate the vintage or harvest date.
This is often an excellent indicator of transparency.
4. Check the origin of the olives
Not all oils have the same level of traceability.
The following information is particularly interesting:
- country of origin;
- production region;
- olive variety;
- the producer.
Monovarietal oils are particularly good for discovering the full personality of an olive variety.

5. A PDO is a valuable benchmark
A Protected Designation of Origin (PDO) guarantees a strong link between an oil, its terroir, and the expertise behind it.
It specifically regulates:
- origin of the olives;
- authorized varieties;
- production methods;
- traceability;
- quality controls.
Not all excellent oils are PDO, but a PDO provides an extra guarantee of consistency and authenticity.

6. Polyphenols are an excellent indicator
Polyphenols are compounds naturally present in certain extra virgin olive oils.
They contribute to:
- bitterness;
- pungency;
- the stability of the oil.
An oil that is naturally rich in polyphenols generally has more character and better resistance to oxidation.

7. Packaging is far from a detail
Light is one of the primary enemies of olive oil.
An opaque bottle protects aromas better and limits oxidation.
Prefer:
- tinted glass;
- opaque bottles;
- food-grade metal tins.
Avoid transparent bottles exposed to bright light for several months as much as possible.
8. Trust your senses
A good olive oil can also be recognized during tasting.
It should evoke fresh aromas:
- cut grass;
- tomato;
- olive leaf;
- artichoke;
- almond.
It should never smell rancid, like vinegar, or show signs of mold or fermentation.
Common misconceptions
Is a very green oil necessarily better?
No.
The color depends mainly on the olive variety and its stage of maturity.
It is not a reliable criterion for quality.
In fact, this is why professional tastings are conducted in blue glasses, so as not to influence the tasters.
In summary
Before buying olive oil, check:
- the extra virgin category;
- the fruitiness or harvest time (early or ripe);
- the harvest date;
- the origin;
- the variety;
- any potential PDO;
- the packaging;
- the aroma profile.
A quality oil is above all an oil that reflects its terroir and respects the fruit it comes from.
