HOW LONG DOES OLIVE OIL LAST?
We get this question a lot!
Olive oil, like other oils, has a fairly long shelf life. Research suggests that olive oil is good for anywhere between 20 and 24 months after its crush date. However, after opening a bottle of oil, you’ll want to use it up within a few months. Olive oil is a perishable item, so it does have an expiration date.
Of course, like with almost all products that come with a best-by date, the oil will remain at good quality for longer. That’s true provided that you follow the storage guidelines outlined earlier.
How long past the date on the label will the EVOO be good? It’s impossible to say, as it depends on both storage methods and the quality of the oil itself. A reputable brand like D’ Olivo will likely keep its freshness for longer than a store bought olive oil. Our brand tests for chemical standards that are far above the average olive oil company and ensures a fresher, longer lasting olive oil with high antioxidents.
Once you open the bottle, the oxidation process speeds up a bit thanks to having access to fresh air. For the best quality, you should try to finish the bottle within a year, but it should stay okay for up to 18 months.
Olive oil (unopened) Best by date or up to 24 months from crush date
Olive oil (opened) Use between 12-18 months (also depends on storage methods)
Please note that all the periods above are estimates. Sometimes the oil will go rancid even quicker, other times it will stay fresh for even longer.
