It’s a staple item in kitchens across the UK.
But it turns out you’ve probably been storing your olive oil wrong.
While many people like to keep their olive oil next to the hob for easy access, experts from Which? have warned that this could actually make the liquid go rancid more quickly.
Instead, they advise storing it in a cool, dark place.
‘Keeping your olive oil in a cupboard away from light, heat and oxygen will help to prolong its life and prevent it going off too quickly,’ Which? explained.
Unlike wine, olive oil does not get better with age – so you shouldn’t let it hang around for years.
‘Once the bottle is opened it’s exposed to oxygen, which causes the oil to deteriorate,’ the experts added.
‘For maximum taste and health benefits, use within a couple of months.’

While Which? advises keeping your olive oil away from any heat sources, it’s also best to avoid the fridge.
‘Don’t store it in the fridge,’ the experts cautioned.
‘You might have heard that keeping your olive oil in the fridge will help it last longer, but our experts don’t recommend this.
‘Keeping it in a cool, dark cupboard is best.’
The experts also encourage you to pay close attention to the packaging.
‘Our experts recommend avoiding oil sold in clear plastic bottles, which can negatively impact the flavour of the oil,’ it explained.
‘Ideally, opt for a tin or a dark-coloured glass bottle rather than a clear one.
‘This helps to block out light and prevent the oil from deteriorating, both on the shop shelves and when you get it home.’
