Does Olive Oil Go Bad?
Olive oil should smell fresh and herbaceous, reminiscent of a garden, says Hirschbein.

If your olive oil has gone bad, Itll have a waxy, crayon-like taste.
The easiest smell to remember is play dough.
This is typically the result of inadequate storage and exposure to damaging light, heat or air.
How Long Does Olive Oil Last?
Olive oil’s shelf-life depends on whether it’s unopened or opened and how it’s stored.
Once you open it, check that to always seal it tightly, Hirschbein says.
How Should Olive Oil Be Stored?
Hirschbein says to think of olive oil like a fresh juice.
Bottle material matters.
This will keep it as fresh meaning itll taste the best - as long as possible.
Store in a cool, dark place.
Ideally between 57 degrees Farenheit and 70 degrees Farenheit, Hirschbein says.
Be careful around sunlight.
Avoid heat sources like stoves or direct sunlight.
Seal properly.
Every time you use your bottle of oil, double-check it is tightly sealed to prevent oxidation.
Oxidation can affect the flavor of the oil, and speed up its aging towards rancidity, Hirschbein explains.
Don’t keep it for too long.
Use olive oil within a few months after opening for the best flavor.
Smell it frequently to ensure it still has the fresh grassy aroma, Hirschbein says.
