7 Mistakes When Buying Olive Oil
How to recognize truly good olive oil
Buying olive oil sounds simple at first.
However, anyone who delves deeper into high-quality extra virgin olive oil quickly realizes:
👉 The differences are enormous.
There are often worlds between industrial mass-produced goods and high-quality olive oil from Greece –
in taste, production, and quality.
When buying, many people primarily pay attention to:
- the price
- the color
- or a nice label
But this is exactly where the biggest mistakes often happen.
Why the quality of olive oil is so important
A high-quality extra virgin olive oil is much more than just a cooking oil.
It stands for:
- careful harvesting
- gentle processing
- freshness
- aroma
- and authentic Mediterranean enjoyment
Especially in Mediterranean cuisine, olive oil plays a central role –
not only in terms of taste but also culturally.
But how do you recognize truly good olive oil?
Mistake #1 – Only paying attention to the price
Good olive oil from Greece is not made by chance.
High-quality olive oil requires:
- healthy olives
- careful harvesting
- quick processing
- cold extraction
- and experience
Very cheap oils, on the other hand, are often:
- blends from various origins
- industrially processed
- or significantly older
Why high-quality olive oil costs more
Small producers often prioritize quality over quantity.
Especially traditional olive varieties like the Koroneiki olive yield less,
but offer a more intense aroma and a higher content of polyphenols in the olive oil.
👉 Quality requires time, care, and experience.
Mistake #2 – Automatically confusing mild with better
Many people think:
👉 The milder an olive oil tastes, the higher its quality.
But the opposite is often true.
A high-quality extra virgin olive oil can be:
- slightly bitter
- fruity
- and pleasantly pungent.
Bitterness and pungency are quality characteristics
Early harvested olives, in particular, contain many natural polyphenols.
These provide:
- character
- freshness
- and the typical slight catch in the throat.
👉 The Koroneiki olive, in particular, is one of the most polyphenol-rich olive varieties worldwide.
Mistake #3 – Misjudging the color
Green olive oil is often automatically considered higher quality.
However:
👉 The color says little about the actual quality.
The color depends on:
- olive variety
- ripeness
- chlorophyll content
- harvest time
Why Koroneiki oil is often intensely green
The Koroneiki olive often yields intensely green oils
with a fresh, lively aroma.
But golden olive oils can also be excellent.
👉 The taste is always decisive – not the color.
Mistake #4 – Ignoring origin and producers
A high-quality olive oil from Greece should be transparent.
Pay attention to:
- origin
- producer
- region
- harvest information
Olive Varieties / Koroneiki Olives
Why small producers often deliver better quality
Small family businesses often work:
- more carefully
- more traditionally
- and closer to nature
Especially in the Peloponnese, where the Koroneiki olive has been cultivated for thousands of years,
quality often takes precedence over mass production.
Mistake #5 – Improper storage of olive oil
Even the best olive oil loses quality
if stored improperly.
The biggest enemies of olive oil
- Light
- Heat
- Oxygen
👉 Therefore, high-quality extra virgin olive oil should be:
- stored in a dark place
- kept cool
- and tightly sealed.
That's why we use light-protected packaging and dark bottles.
Mistake #6 – Thinking that olive oil cannot be heated
A widespread myth.
In fact, high-quality olive oil is very suitable for frying and cooking.
Why olive oil is heat-stable
Olive oil contains:
- stable fatty acids
- natural antioxidants
- valuable polyphenols
👉 This makes it much more stable than many people think.
Especially in Mediterranean cuisine, olive oil has been routinely heated for centuries.

Mistake #7 – Keeping olive oil for too long
Many treat olive oil like wine.
But:
👉 Freshness is crucial.
Why fresh olive oil tastes better
A fresh olive oil impresses with:
- fruity aromas
- lively structure
- intense flavor
Over time, it loses its freshness and character.
👉 Therefore:
The fresher the oil, the better the taste experience.
