Why does extra virgin olive oil change color? No, you haven't been misled
If you've opened your bottle of EVOO and the color isn't as green as it was on day one, take a breath. You haven't been misled, and your oil hasn't gone bad. You're witnessing one of the most natural — and most misunderstood — phenomena in extra virgin olive oil. We'll walk you through all of it here.
In this article
1. Filtered vs Unfiltered: why they change differently
Not all EVOO changes at the same pace. The type of oil you have at home makes all the difference.
🟡 Filtered EVOO
All pulp residues are removed during production. The result is a more stable oil that holds its color for much longer. Optimal shelf life: up to 2 years.
Ideal if you want stability and worry-free use over many months.
🟢→🟡 Unfiltered EVOO
Pulp particles remain suspended, giving the oil its distinctive flavor. Over time, they settle to the bottom and the oil becomes clearer. Best consumed within 1 year.
Ideal if you're after maximum flavor and aromatic intensity.

The one that changes color the most — and the one with the most flavor.
2. The external factors that speed up the change
Beyond the type of oil, there are things you do — or don't do — at home that accelerate color change and, more importantly, can actually degrade the quality of the oil itself.
If your oil has changed color but the flavor is still intense, fruity, and peppery on the finish, your oil is perfectly fine. Color shifts before quality does. Only when rancid or stale flavors appear is there a real problem.
3. The olive variety and its starting color
Before time or light play any role, the initial color of your EVOO is determined by the olive variety and when it's harvested. The differences between varieties can be striking.
Still-green olives. Very deep green color. Bitter and peppery flavor, with herbaceous notes and a high concentration of polyphenols (antioxidants).
More mature olives. Golden color from the start. Smoother and fruitier flavor. A different profile, equally valid — it comes down to taste and culinary use.
A real example: our Arraigo Unfiltered is made primarily from Hojiblanca (a late-ripening variety) blended with a touch of Arbequina (earlier ripening) and Picuda, which adds a gentle peppery finish. The result is a more golden-hued oil from the outset — not because it's inferior, but because that's simply the nature of that variety. Every EVOO has its own palette.
4. How to tell if your oil is still good
Color is just a visual indicator — and not the most reliable one. These are the three senses that will actually tell you whether an oil is in good shape:
A good EVOO smells of fresh grass, green tomato, almond, or apple. If it smells rancid, plasticky, or simply "off," then yes — there's a problem.
Try a small spoonful at room temperature. It should taste alive — bitter, peppery on the finish, with character. If it tastes flat or like old fat, it's past its best.
Unfiltered EVOO: consume within one year of bottling — all the more reason to choose a freshly bottled olive oil, like everything you'll find in our online shop. Filtered EVOO: up to 2 years from bottling. If you're within the window and the smell and taste are right, you have a perfect oil.

"When I saw my oil had changed color I was really worried. After reading this I understood it was completely normal — and now I know exactly why I buy the unfiltered. The flavor is incomparable."

"I've been ordering Arraigo unfiltered for 4 seasons in a row. Beautiful deep green color, very dense, bitter, peppery — a proper EVOO. And the team is always incredibly helpful whenever you have a question."

In a nutshell
A color change in your EVOO is not a warning sign — it's a sign of authenticity. An oil that evolves is a living oil, made from real fruit with nothing artificial.
What really matters is that the flavor and aroma stay intense. If they do, you have a great oil at home. And if you want to better understand what you're buying — or try one that shows you exactly what we mean — we're right here.

Porque el envase no es en lata de chapa, creo que se conservaría mejor el aceite.
Un saludo.
