How Should Olive Oil Be Stored?
The three enemies: light, heat and oxygen
Ultraviolet light triggers oxidation that flattens aroma; warmth accelerates the same chemistry; and every opening of the bottle lets in oxygen that gradually dulls the oil. Olive oil rarely “spoils overnight” — it fades step by step, which is why the same bottle can taste noticeably livelier in its first weeks than months later.
Choosing the right container
Dark glass, lacquered tin and stainless steel all block the light that clear glass lets through. This is why Bodrum Olive House bottles its oils in dark glass and offers 5 L volumes in tin — the packaging itself is part of quality protection. Keep oil in its original container; avoid decanting into clear cruets left on a sunny counter.
Where to keep it at home
A kitchen cupboard away from the oven is ideal — stable, dark and roughly 14–20°C. The worst common spot is the shelf beside the stove, where heat cycles daily. Refrigeration is not harmful — the oil clouds and may solidify, then clears again at room temperature — but a cool pantry is simpler and just as effective.
How long does olive oil last?
A well-made extra virgin olive oil, stored properly and unopened, is typically at its best within 18–24 months of bottling — check the best-before date on the label. Once opened, plan to finish the bottle within one to two months for peak aroma. High-polyphenol oils such as early harvest hold their character longer than mild, late-season oils.
- Store away from light and heat — a cupboard below about 20°C is ideal.
- Keep the cap tightly closed; oxygen dulls aroma after opening.
- Dark glass, tin or stainless steel protect oil far better than clear glass.
- For peak character, finish an opened bottle within one to two months.

Frequently Asked Questions
Can olive oil be stored in the refrigerator?
Yes, but it is rarely necessary. Chilled olive oil turns cloudy and may partially solidify — this is harmless and reverses at room temperature. A cool, dark cupboard gives the same protection with none of the inconvenience.
Does olive oil expire?
Olive oil does not become unsafe the way fresh food does; it oxidizes. An oil past its prime smells flat, waxy or rancid instead of fresh and fruity. Check the best-before date and trust your nose.
Why is olive oil sold in dark bottles?
Dark glass blocks the light that drives oxidation. Clear bottles look attractive on a shelf but expose the oil to constant light damage — one reason premium producers, including Bodrum Olive House, use dark glass and tin.
