Truffle sales in Umbria: guaranteed not synthetic from the bottle Photo: stock.adobe.com/Eliane Haykal

Sometimes there are just a few drops of artificial oil between luxury and legend: there are few products that cause as much confusion as truffles - real or "fake"? How to taste the difference.
Truffles are considered the pinnacle of Italian cuisine - rare, expensive, sought-after. In Alba in the Piedmont a kilo of white truffles can cost up to 10,000 euros. No wonder that the scent is imitated industrially for a cheaper flavour variant. For the guest, both smell tempting at first - regardless of whether it's the real tuber or billo perfume from a bottle.

Why truffles are so expensive
Real truffles do not grow on plantations, but in the wild, under oak or hazel trees, in calcareous soil. They cannot be cultivated, they can only be found. This requires specially trained dogs that recognise the smell of the tubers. It takes years to train them and good animals cost several thousand euros.
Olive oil from Italy: the most important facts about the green gold
The well-known "truffle oil" almost never contains real mushrooms. The intense fragrance usually comes from the artificial flavouring 2,4-dithiapentane, which imitates the typical smell. Artificial oil smells strong and even, whereas real truffles have a complex and quickly fading odour - with notes of earth, hay and nuts.
How to recognise real truffles in a restaurant
In restaurants, genuine truffle oil or genuine truffle flavour can often be recognised by how complex and nuanced the taste is.
Depending on the type of truffle, real oil shows subtle differences: for example, honey-sweet hay tones and light garlic notes in white truffles, earthy-nutty nuances in black truffles. Cheap or synthetic oils, on the other hand, have a one-sided, penetrating and strongly garlicky flavour.
Some products or mushroom dishes are brushed with flavoured oils - at first it seems to smell like truffles, but the taste remains artificial.
Practical tips in the restaurant:
- Look for a complex, not too intense aroma reminiscent of hay, spices, musk and honey - not just garlic.
- Genuine truffle oils are subtle; if the dish seems strong or chemical, flavour is usually involved.
- Asking helps: The kitchens should provide information as to whether real truffles are used.
- Real truffle pieces are visibly planed. If only truffle oil is used, you will only see small drops or a thin layer.
- Cheap products have a pungent or "ammonia-like" odour.
The flavour of the original
Anyone who has ever tasted real truffles will recognise them: the aroma is delicate, the taste warm and earthy - never loud, but elegant. Whether in Piedmont or at the Italian round the corner - truffles are never the same as truffles. If you taste carefully, you will notice the difference - and recognise the fake oil immediately.
