The Best Containers for Storing Olive Oil
The best containers for storing olive oil are dark glass bottles or opaque stainless-steel tins — anything that keeps light out, seals tightly against air, and doesn’t leach into the oil. Clear glass and plastic are the worst offenders: clear glass lets in the light that turns good oil rancid, and plastic can pick up off-flavours and shed traces of itself into the oil over time. If you take home just one rule, make it this: keep your oil in the dark, keep it sealed, and keep it cool.
Olive oil has four great enemies — light, heat, air (oxygen) and time. A good container fights the first three. Get the vessel right and a fresh oil will hold its flavour and its gentle peppery kick for many months instead of fading within weeks.
What actually matters in a container
It’s easy to get distracted by pretty bottles. What counts is how well the material does three jobs.
Blocking light. Ultraviolet and visible light drive a reaction called photo-oxidation, which strips out the delicate compounds that give extra virgin oil its fruity, grassy character and its natural antioxidants. This is why the good stuff is almost always sold in dark green, amber or opaque bottles. A clear bottle on a sunny windowsill is the fastest way to ruin an oil, however lovely it looks.
Sealing out air. Every time oxygen meets oil, it nudges it a little closer to rancid. A screw cap or a proper cork that reseals tightly matters far more than the shape of the bottle. Pouring spouts that don’t close are convenient but let air trickle in between uses.
Staying chemically neutral. The material must not give anything back to the oil. Glass and food-grade stainless steel are inert — they sit there doing nothing, which is exactly what you want. Most plastics are not truly neutral: oil is a solvent, and over weeks it can pull plasticiser compounds out of the container and take on a faint plastic note. Reactive bare metals such as copper, iron and brass are worse still and can speed up spoilage, so they’re fine as decorative jugs for the table but not for storage.
Dark glass and tin vs clear glass and plastic
Here’s how the common options stack up. For everyday kitchen use, dark glass is the sweet spot; for larger volumes or shipping, a lined tin is hard to beat.
| Container | Blocks light? | Neutral / inert? | Verdict |
|---|---|---|---|
| Dark glass (amber/green) | Mostly — good | Yes | Best all-round for the kitchen |
| Stainless steel / lined tin | Yes — fully opaque | Yes (food-grade) | Best for larger volumes & shipping |
| Glazed ceramic / stoneware | Yes, if opaque | Yes, if fully glazed | Good, if it seals; check the glaze |
| Clear glass | No | Yes | Only if stored in a dark cupboard |
| Plastic (PET/HDPE) | No (clear) / some | No — can leach | Avoid for anything but short-term |
| Bare copper / brass jug | Yes | No — reactive | Table decoration only, not storage |
Getting the most from whatever you use
The container is half the battle; the rest is habit. A few things that make a real difference:
- Store it cool and dark. A cupboard away from the hob is ideal — roughly 14–20°C. Never keep your everyday bottle on the counter next to the cooker, however handy it seems.
- Mind the fridge myth. Cold won’t harm the oil, but it will turn it cloudy and thick; it clears again at room temperature. Refrigeration isn’t necessary for a bottle you’ll finish within a couple of months.
- Buy a size you’ll actually use. Once opened, oil is on the clock. If you cook with it now and then, a 500ml dark bottle beats a 3-litre tin you’ll still be finishing a year later.
- Decant sensibly from big tins. If you buy a large tin, top up a small dark bottle for daily use and keep the tin sealed and cool. Every opening of the main container lets in air.
- Keep the cap on tight and give the neck a quick wipe so the seal seats properly.
As a rough guide, a well-made extra virgin oil is at its best within about 12–18 months of pressing and, once opened, is happiest used up within a month or two — sooner if it lives somewhere warm or bright. The container buys you time; it doesn’t stop the clock.

Storing olive oil: common questions
Is it OK to keep olive oil in a clear glass bottle?
Only if you keep it in the dark. Clear glass offers no protection from light, so a clear bottle left out on a shelf or windowsill will go stale far quicker. Tucked inside a closed cupboard, it’s fine — the cupboard is doing the job the dark glass would otherwise do.
Can I store olive oil in a plastic bottle?
It’s best avoided for anything beyond the short term. Oil is a solvent and can slowly pick up off-flavours from plastic, and traces of the plastic can migrate into the oil over weeks. If oil arrives in plastic, decant it into dark glass or a tin fairly soon.
Does olive oil need to go in the fridge?
No. A cool, dark cupboard is plenty. The fridge makes the oil cloudy and semi-solid (harmless, and it reverses at room temperature), and it’s simply not needed for a bottle you’ll finish within a month or two.
What’s the single most important thing?
Keep light and air out. A tightly sealed dark bottle or opaque tin, stored somewhere cool and shaded, will preserve flavour better than any clever gadget. This is general food-storage guidance rather than any kind of medical advice.
