While a healthy splash of olive oil can improve almost any dish, prices of the delightful vegetable oil are at an all-time high.

A 500ml bottle of Filippo Berio’s extra virgin olive oil now costs around £7.50 – an increase of £3.75 from 2022 – thanks to a series of poor harvests pushing up costs. 

However, Walter Zanre, boss of Filippo Berio, has criticised supermarkets for ‘taking the mickey out’ of shoppers, saying that his brand reduced wholesale prices twice last year but the savings have not been passed on to consumers. 

‘I think what’s causing it is that even the supermarket was surprised at how resilient the shopper was at high prices, so the view is they don’t need to give it all away for nothing,’ he told Sky News, describing the situation as ‘immensely frustrating’ for producers.

So, as prices continue to soar for a small bottle of olive oil, how can you tell which supermarket varieties are truly worth it?

From the type of bottle used to prevent damage to the oil, alongside specific details of the product’s source and certification, there are a number of tell-tale signs that your go-to olive oil may be somewhat inauthentic. 

Indeed, of the 10 popular brands The Daily Mail assessed, nearly half showed signs of its olive oil lacking in high quality, despite the often eye-watering price tag.

Professor Maurizio Servili previously told The Daily Mail: ‘Olive oil is not a cheap product. It’s easier and more economical to make frauds of an expensive product than a cheap product.’

Whether you’re using olive oil to add a hint of flavour to your salads and vegetables, or even for cooking, knowing the difference between ‘real’ and ‘fake’ options can help you avoid splurging on less desirable products.
