Not all olive oil is created equal, and most people only realize that when they actually start reading the label.
You are standing in the supermarket, bottle in hand, and you read “extra virgin olive oil” on the label. Pure, natural, healthy, right? Unfortunately, reality is different. A large proportion of the olive oil you buy in a Belgian supermarket is refined, blended with cheaper oils, or sourced from countries outside the EU with little oversight of quality or processing methods.
In this guide, we explain honestly what genuine extra virgin olive oil is, how it differs from regular olive oil, what you need to know about labels in 2026, and where you can buy truly good EVOO in Belgium.
What exactly is extra virgin olive oil?
Extra virgin olive oil—abbreviated as EVOO—is olive oil pressed directly from the fruit, without heating or chemical processing. Exclusively mechanically extracted, during the first cold pressing. It sounds simple, but it makes a big difference.
Genuine EVOO still contains all the substances that the olive naturally contains:
- Polyphenols — powerful antioxidants with anti-inflammatory effects
- Oleocanthal — a polyphenol with effects similar to ibuprofen, but obtained through food
- Monounsaturated fatty acids (omega-9) — good for the heart and blood vessels
- Vitamin E — a fat-soluble antioxidant that protects cells
- Natural aromas and flavor compounds — which are completely lost when heated
In refined olive oil, all these substances largely disappear during the production process. And that is precisely why the difference matters—not only for the taste, but for your health.
Why isn’t most supermarket olive oil what you think it is?
Supermarket olive oil undergoes an industrial process consisting of several steps, and each step removes something valuable.
1. Heating and refining
To process unusable or overripe olives after all, the oil is industrially refined: heated, deodorized, and bleached. Above approximately 40 °C, polyphenols and antioxidants begin to break down. What remains is a flat, neutral fat—without flavor, aroma, or biological activity.
2. Blending with cheaper oils
After that, a small amount of genuine extra virgin olive oil is often added—just enough for the product to legally be called “olive oil” and to give it a little color and aroma. How much exactly? The manufacturer is not required to state that. Sometimes it is also blended with oils from outside the EU, even though “EU/non-EU” appears in small print on the label.
3. Low quality as a base
Overripe, damaged, or even already fermented olives are often used for this refining process—olives that would be unsuitable for genuine extra virgin olive oil. Yet they end up in large volumes of supermarket oil under a label promising "extra virgin" or "mild."
The result? A product that looks like olive oil but has retained little of its original qualities—and whose contents, until recently, were difficult to verify from the label.
How to read an olive oil label correctly (Checklist)
This is what to look for when you have a bottle of olive oil in your hands:
Good signs:
- "First cold pressing" or "cold-pressed"—explicitly stated
- "Mechanically obtained" or "extra virgin" with supporting evidence (see acidity)
- Low acidity: max. 0.8% for EVOO—the lower, the better. Below 0.5% is exceptional
- EU origin of the olives—preferably one specific country or region
- Certified organic (BIO)—no synthetic pesticides
- Independent laboratory analyses available via a link or QR code
- Packaged in a dark bottle—protects against light oxidation
Warning signs:
- No mention of the extraction method or acidity
- "Blend of EU and non-EU olive oils" in small print
- Noticeably low price for the quantity
- Clear, transparent bottle—oil exposed to light oxidizes more quickly
- Vague terms such as "mild," "pure," or "delicate" without further specification
Regarding organic certification: certified organic olive oil means that the olives are grown without synthetic pesticides or fertilizers. This is not the same as extra virgin, but it is an additional quality guarantee indicating that the product and cultivation are taken seriously.
Where can you buy genuine extra virgin olive oil in Belgium?
There are four ways—each with its advantages and disadvantages.
1. At a specialized delicatessen shop or oil library ⭐ Recommended
Specialty shops focused on olive oil often offer EVOO from small producers with traceability, a specific harvest year, and staff who can explain where the oil comes from. You can often taste it before you buy.
Explicitly ask about: the harvest year (the more recent, the more polyphenols), the country of origin of the olives, and whether a laboratory analysis is available.
Downside: the selection in Belgium is limited, and prices rise quickly. Not always the most practical option for everyday use.
2. Organic shops and health food stores
The chances are better here than in the supermarket; they more often carry EVOO from smaller producers who pay greater attention to origin and quality. But here too, “organic” does not automatically mean “first cold pressing” or “unblended.” Specifically look for the acidity and pressing method on the packaging, and check the country of origin of the olives — not just where the oil was bottled.
3. Supermarket
You can find something good there, but you really have to search. Most bottles on the shelf are blends or refined, and this is rarely stated prominently on the packaging. If you still buy from the supermarket: check the acidity, avoid vague origin statements such as “EU/non-EU,” and skip bottles in clear glass.
4. Online from specialized brands ⭐ Recommended for everyday use
An increasing number of quality brands sell directly online without intermediaries, with full transparency about origin, acidity, and certificates. You can take your time comparing, reading labels, and consulting analyses before ordering.
This is also how we work at HANT.

The bottom line
Buying genuine extra virgin olive oil in Belgium is possible, but it requires some attention. Read the label. Check the acidity. Look at where the olives come from, not just where the oil was bottled. And choose brands that publish their laboratory analyses — because that is the only guarantee that really says something.
A good EVOO doesn't have to be expensive. But a bottle that's too cheap is almost never what it claims to be.
