China: Warning issued over ‘bargain’ olive oil
When a litre of ‘Italian olive oil’ costs half of what the supermarket charges, something has usually been left off the label. Nine times out of ten that something is one word: pomace. It is legal, it is edible, but it is not what most people think they are buying.
Every so often a market watchdog somewhere issues the same quiet warning: be careful of the bargain olive oil on the stall. The story repeats from Shanghai to London because the trick is always the same. A bottle carries a confident English front label — produced in Italy, a handsome price of a few dollars a litre — while the small print, often only in the local language, admits the truth the front hides. The oil is not extra virgin. It is not even virgin. It is olive-pomace oil, the bottom rung of the ladder, and the low price is the single most reliable sign of it.
What pomace oil actually is
When olives are pressed for oil, the first mechanical extraction gives you the good stuff — virgin and extra virgin oil, squeezed from the fruit with nothing but pressure. What is left behind is a damp cake of skins, pulp and crushed stones called pomace. That cake still holds a little oil, but it cannot be wrung out mechanically, so it is treated with heat and a chemical solvent (typically hexane) to strip out the last of it. The result is crude and inedible until it is refined — deodorised, bleached, neutralised — which removes the harshness but also nearly everything that gives olive oil its taste, aroma and character. A small amount of virgin oil is usually blended back in at the end simply so it tastes of anything at all. The finished product can be legally sold as olive-pomace oil. It cannot be sold as olive oil, and it certainly cannot be called virgin or extra virgin.
Why the cheap bottle is so cheap
Pomace oil exists for a reason: it is a genuine, safe cooking fat, cheap to make from a waste stream, and widely used for frying in commercial kitchens where flavour does not matter. There is nothing wrong with buying it as what it is. The problem is the deception at the margins — a bottle dressed up in the language of premium Italian oil, priced to undercut the real thing by half, with the word pomace demoted to a footnote or dropped from the translated label entirely. Complaints about these bargain oils are almost always the same: a flat or off taste, a greasy mouthfeel, sometimes a residue. That is not bad luck. It is the grade doing exactly what the grade does.
How to protect yourself
The price is your first and best defence. Real extra virgin costs money to make — a lot of fruit yields a little oil, and it must be pressed quickly and gently — so a litre selling for a fraction of the going rate is telling you something. Read the actual grade, not the marketing: the words extra virgin olive oil mean one specific, tested thing; pomace oil, olive oil (plain, meaning refined-plus-virgin) and vague phrases like ‘pure’ or ‘light’ all mean something lesser. This is the same murk that lets ordinary oil be dressed up as grand, which we pull apart in how olive oil is cut and the extra virgin that isn’t.
| Grade | How it is made | What to expect |
|---|---|---|
| Extra virgin | First mechanical press, no heat or solvent, tested to a standard. | Real flavour, aroma, pepper; the price reflects it. |
| Virgin | Mechanical press, slightly higher acidity, less strict. | Decent, honest oil; a step down in finesse. |
| ‘Olive oil’ / ‘pure’ | Refined oil blended with a little virgin. | Neutral, mild; fine for cooking, little character. |
| Olive-pomace oil | Solvent-extracted from the leftover paste, then refined. | Cheapest; flat taste; the ‘bargain’ bottle to beware. |
Buying without getting caught
- Treat a suspiciously low price as a warning, not a win — real extra virgin cannot be made that cheaply.
- Read the grade in full, and read the back label and small print, not just the glamorous front.
- Learn the one word to watch for: pomace. It is legal, but it is the lowest grade.
- Buy pomace oil deliberately if you want a cheap frying fat — just never mistake it for the good stuff.
- For flavour, buy a named extra virgin with a harvest date and a real address behind it.
Bargain olive oil: common questions
Is olive-pomace oil safe to eat?
Yes. It is a legal, refined cooking oil widely used for frying. The issue is not safety but grade and honesty — it is the lowest tier and should be sold, and priced, as what it is.
How is pomace oil different from extra virgin?
Extra virgin is pressed mechanically from the fruit with no heat or chemicals. Pomace oil is solvent-extracted from the leftover paste and then refined, stripping out most of the flavour and aroma.
Why is the bargain bottle so cheap?
Because it is made from a waste stream at low cost. Real extra virgin is expensive to produce, so a half-price litre is usually a lower grade wearing a premium-looking label.
How can I spot mislabelled oil?
Read the grade, not the marketing. Look for the exact words ‘extra virgin’, check the back label and small print for ‘pomace’, and be suspicious of a price far below the norm.
Is ‘produced in Italy’ a guarantee of quality?
No. It can mean the oil was merely bottled or blended there from fruit grown elsewhere. Origin claims say little about grade — the grade word and the price tell you far more.
Here is the trade’s plain rule: the price tag is the honest label. Nobody makes true extra virgin and sells it at half the market rate for love — the maths does not work. When you see it, assume a lower grade in disguise and read the small print for the word pomace. There is a proper place for pomace oil, in a deep-fryer where flavour is irrelevant, but it has no business wearing the clothes of a premium bottle. Buy it on purpose or not at all.
