How to Store Olive Oil
Élodie Marchand · Head of Sourcing, IOC-trained panel taster · Updated 2026-07-30
Store olive oil in a closed, opaque container, in a cool dark cupboard between roughly 57–70°F, away from the stove and out of direct light. Light is the fastest destroyer, heat the second, oxygen the third. Do not decant into a clear cruet that lives on the counter, and do not refrigerate — chilling causes harmless clouding but adds nothing, since condensation on repeated warming can introduce moisture. Once opened, aim to finish a 500 ml bottle within about three months; buy sizes that fit that pace rather than the largest tin on offer.
The three enemies
Light triggers photo-oxidation and strips aroma within weeks in clear glass. Heat roughly doubles the rate of degradation for every 18°F increase. Oxygen enters every time you open the bottle, which is why a half-empty container ages faster than a full one.
Practical setup
Keep the working bottle in a cupboard beside the stove, not above it. If you buy a three-liter tin, decant into a smaller dark bottle and leave the tin sealed. Replace pouring spouts that cannot be closed.
Frequently asked questions
- Should olive oil be refrigerated?
- No. Refrigeration clouds the oil harmlessly but offers little benefit over a cool cupboard, and repeated warming risks condensation.
- Does olive oil expire?
- It does not spoil in a microbial sense, but it goes rancid. Rancid oil smells like crayons, putty or old nuts and should be discarded.
- How long does an opened bottle last?
- About three months for a 500 ml bottle kept closed and cool. Larger opened formats fade faster than most people expect.
