An olive oil label has two jobs. One is legal: tell you what is in the bottle. The other is to sell it to you. Both jobs share the same small space, and the selling words are often bigger. Here is how to read past them.
Start with the grade
The grade is the most important phrase on the label, and it is regulated. In the UK and the EU, olive oil sold in shops has to be one of four categories:
- Extra virgin olive oil
- Virgin olive oil
- Olive oil composed of refined olive oils and virgin olive oils, usually sold as plain “olive oil” on the front, with the full name in smaller print
- Olive-pomace oil
Extra virgin is the top grade. It has to pass both laboratory tests and a trained tasting panel. A bottle sold as plain “olive oil” is usually mostly refined oil with some virgin oil added for flavour. That is a different product, not a weaker version of the same one.
Find where the olives came from
Extra virgin and virgin oils must state their origin. Read this line carefully. It is often small print, and it often tells the real story.
- A single country means the olives were harvested and the oil was made there. If the olives were grown in one country and milled in another, the label has to say both, in wording such as “extra virgin olive oil obtained in Italy from olives harvested in Greece”.
- “Blend of olive oils of European Union origin” means the oil came from more than one EU country.
- “Blend of olive oils not originating in the European Union”, or a mix of EU and non-EU wording, means the oil came from several countries, some or all outside the EU.
Watch for place names used as decoration. A bottle can be “bottled in Italy”, or carry an Italian-sounding brand name, and still hold oil from somewhere else. “Packed in” and “bottled in” tell you where the bottle was filled, not where the olives grew. The origin line is the one that counts.
Look for a harvest date
A harvest date is optional, which is exactly why it is worth looking for. Olive oil is at its best in the months after harvest and fades from there. A producer who prints the harvest is telling you how old the oil is.
Under UK and EU rules, a label can only state a harvest year if all the oil in the bottle comes from that harvest. Harvests run across the turn of the year, so you will often see two years, such as “2025/2026”.
If there is no harvest date, the best-before date is all you have. It usually counts from bottling, not from picking, so it tells you much less.
Words that sound official and mean little
- “First cold pressed”. Most modern mills do not use a press at all. They crush the olives and separate the oil in a centrifuge, and there is no second pressing. Under UK and EU rules, “cold extraction” may only appear on virgin and extra virgin oils extracted below 27°C, by centrifuge or percolation. “First cold pressing” has the same 27°C limit and also needs a first mechanical pressing in a traditional hydraulic press, which few mills still use. On a centrifuge-made oil, “cold extraction” is the accurate phrase.
- “Pure”. Not a grade. On a label it usually sits on the refined plus virgin blend sold as plain “olive oil”.
- “Light” or “mild”. This describes flavour and colour, usually of a refined oil. It says nothing about quality.
- “Mediterranean”, “traditional”, “artisan”, “premium”. None of these is a grade or a defined term in the olive oil rules. They tell you how the brand wants you to feel, not what is in the bottle.
Acidity numbers
Some bottles print a free acidity figure. Acidity is one of the lab tests behind the grade, and extra virgin must be at or below 0.8%. It is not something you can taste, and it is only one of several measures. That is why UK and EU rules say a label that states acidity must also state the peroxide value, wax content and ultraviolet absorption, in the same size of type and in the same field of vision. If you see an acidity figure standing alone on the front, the label is selling, not informing.
A thirty-second label check
- Grade: does it say extra virgin olive oil?
- Origin: one country, or a blend of several? How specific is it?
- Harvest: is there a harvest date, and how long ago was it?
- Container: dark glass or a tin, or clear glass under shop lights?
- Producer: is there a company name and address you could actually contact?
That is it. Everything else on the label is there to make you feel something. Feelings are fine, but they should not do the work of facts.
Our label
We try to make our own label answer those questions plainly. Dukat oil is extra virgin, from Dukat, a village in Vlorë county, Albania, and it comes in dark glass. Every bottle carries a harvest date and a batch code, and it is sold by Dukat Olives, a UK company. You can see the bottle in the shop and judge the label for yourself.
