Can You Use Olive Oil After the Best-Before Date?
Written by Jordan Morley · Reviewed against FSA date labelling guidance · Last updated 28 October 2026
Yes. Olive oil has a best-before date, which is about quality rather than safety, so it is usually fine to use after the date. Check that it looks and smells normal.
Why it's usually fine past the date
A best-before date is the maker's estimate of how long olive oil stays at its best. After it, it becomes stale and eventually rancid, especially with light, heat and air; it doesn't suddenly become unsafe. The FSA says food is generally safe to eat after its best-before date, and using your own judgement also cuts food waste. Throw it away if you see: a smell like crayons, putty or old nuts, or a harsh bitter taste.

Common questions
How long does olive oil last after the date?
USDA FoodKeeper gives opened or unopened olive and vegetable oils about 6–12 months in the pantry. Keep it away from heat and light. If it smells like crayons or putty, it is rancid. That doesn't make you ill but it tastes bad.
How can I tell if olive oil has gone off?
Look for a smell like crayons, putty or old nuts, or a harsh bitter taste. If none of those apply and it looks, smells and tastes normal, it is fine.
What actually changes after the best-before date?
It becomes stale and eventually rancid, especially with light, heat and air. That's a drop in quality, not a safety problem (FSA).
What is the difference between use-by and best-before?
Use-by is about safety: do not eat after it. Best-before is about quality: the food is often fine after it, just past its best. Check which one is on your label.
