How long does olive oil last?
Quick answer
Olive oil keeps for 18 months at room temperature — it doesn't belong in the fridge.
| Where | Safe for |
|---|---|
| 🏠 Room temperature (counter) | 18 months |
| 🧊 Refrigerator (≤40°F / 4°C) | Refrigeration isn't the right storage for this |
| ❄️ Freezer (0°F / −18°C) | Freezing isn't recommended — it ruins the texture or isn't safe |

How to tell if olive oil has gone bad
Pantry items usually go stale before they go dangerous — with a few important exceptions. Trust your senses before any calculator — including ours. Throw olive oil away if you notice:
- An off, sour, or unusual smell that wasn't there when fresh
- A slimy, sticky, or tacky surface texture
- Visible mould or unexpected discolouration
- It's been past the safe window in the table above
⚠️ Bacteria that cause food poisoning often produce no smell, taste, or visible change. Food can look perfectly fine and still make you sick — that's why the time limits matter even when everything seems okay.
Storage tips for olive oil
Airtight containers beat original packaging for anything opened. Most pantry 'spoilage' is really staleness from air exposure.
Store pantry goods cool and dark. Heat and light are what turn oils rancid and fade flavour long before any safety issue.
