Store extra virgin olive oil in a cool, dark, dry place, away from heat, light, and air. These three things are the enemies of olive oil. Exposure to any of them speeds up oxidation and turns a great oil into a mediocre one.
In this guide, we cover every storage rule you need to know, what damages olive oil, how to choose the right container, and how long it actually lasts.
Rule 1: Keep It Away From Heat
Heat accelerates oxidation. The faster olive oil oxidizes, the faster it goes rancid. This is the most common storage mistake people make.
Most people store their olive oil right next to the stove. It looks good there and it is convenient. But appliances like ovens, stoves, microwaves, and dishwashers all give off heat regularly. Storing oil next to them means constant, repeated heat exposure.
A single brief exposure will not ruin your oil. But storing it in a warm spot day after day essentially mimics the homogenization process used to produce commercially refined olive oil. You are degrading a premium product slowly without realizing it.
Move your oil to a closed cabinet away from all appliances. It does not need to be far — a cabinet on the opposite side of the kitchen works perfectly.
What About the Fridge or Freezer?
No to both. Cold temperatures cause olive oil to solidify and lose flavor. The fridge is not a safe storage solution, and neither is the freezer. Both damage the product in different ways. Read more about what happens when you refrigerate olive oil. And here is what happens when you freeze it.
Rule 2: Keep It Away From Light
Light degrades olive oil through a process called photo-oxidation. It happens fast. A bottle sitting in direct sunlight can lose significant quality within days.
Two things protect against this. First, always buy olive oil in a dark glass bottle or metal tin — clear bottles offer almost no protection from light. Second, store your bottle in a dark place, inside a cupboard or pantry, away from both natural and artificial light.
Many people assume only sunlight is a problem. That is not true. Constant artificial light, like under-cabinet kitchen lighting left on all day, can be just as damaging over time. When in doubt, close the cabinet door.
Rule 3: Limit Air Exposure
Olive oil begins to oxidize the moment it contacts air. Every time you open the bottle, oxidation starts. This is normal and unavoidable. The goal is to minimize it.
Always close the bottle tightly after each use. The best caps are DOP-style screw tops, which create a tighter seal than standard pourers. The EU requires these tops for certified products because they limit air entry so effectively.
Do not replace a screw cap with a pourer or spout. They look beautiful on a counter, but they cannot seal properly. A pourer left on your bottle is essentially leaving the bottle slightly open at all times.
Once a bottle is open, aim to use it within 60 days for peak flavor. After that, the oil is still safe to use, but the flavors begin to soften and fade.
Rule 4: Pay Attention to the Harvest Date
Consume extra virgin olive oil within 24 months of the harvest date. Not the best-by date. Not the bottle date. The harvest date.
These are not the same thing. A bottle date tells you when the oil was bottled. A harvest date tells you when the olives were picked. An oil bottled in 2024 could come from a 2021 harvest — a significant difference in freshness.
Rancid olive oil smells of crayons, plastic, or old wax. It is unpleasant to taste and not worth cooking with. Read our full guide on how to tell if olive oil has gone bad. And how to read an olive oil label here.
Rule 5: Buy the Right Container
Storage starts before you even get home. The container your oil comes in matters enormously.
Dark glass is the gold standard. It is chemically inert, blocks UV light, and does not leach any compounds into the oil. Metal tins also perform well, blocking both light and air. Clear glass offers very little protection. Plastic is the worst option — research shows that phthalates and BPA migrate from plastic into olive oil over time, especially under heat or during long storage. Read why you should never store olive oil in plastic here.
A screw cap or DOP-style top is better than a cork or standard stopper. And if a bottle has already been sitting on a brightly lit store shelf for months, its quality may already be compromised before you open it.

What About Microplastics?
Recent research has detected microplastics in commercially tested olive oil samples, including oils packaged in glass — reflecting broader environmental contamination throughout the food system. Choosing dark glass minimizes your exposure significantly. Read what the science says about microplastics in olive oil.
Best Storage Practices: A Quick Summary
- Store in a cool, dark, dry cabinet away from all appliances.
- Use a dark glass bottle or metal tin — never clear glass or plastic.
- Keep the cap tightly closed after every use.
- Do not use a pourer or open spout as a permanent cap.
- Consume within 60 days of opening for best flavor.
- Consume within 24 months of the harvest date.
- Practice first in, first out — use older bottles before opening new ones.
If you live somewhere with extreme temperatures or high humidity, like Arizona, Florida, or Minnesota, consider storing bottles in a box in a closet or under the stairs. Apartment dwellers can use a closed storage cabinet in the living room. Label boxes with the harvest year so you always know what you have.
Do an Audit Right Now
Take five minutes to go through your pantry. Check your olive oil bottles. Look for a harvest date. Smell the oil. If it smells like crayons, wax, or plastic, it has gone rancid. That is okay — here are a few good uses for expired olive oil so it does not go to waste.
Frequently Asked Questions About Storing Olive Oil
Can you store olive oil in the fridge?
No. Cold temperatures cause olive oil to solidify and degrade. Room temperature in a dark, cool cabinet is always better. Read the full explanation here.
How long does olive oil last once opened?
An opened bottle is best consumed within 60 days. The oil remains safe beyond that, but flavor and aroma fade noticeably. Always keep the cap tightly closed between uses.
Why does my olive oil taste flat or bland?
It has likely been exposed to too much heat, light, or air. Olive oil degrades gradually — a flat or mild flavor usually means it is past its peak. Check the harvest date.
Is it okay to store olive oil next to the stove?
No. Stoves and ovens give off heat constantly during and after cooking. Repeated heat exposure speeds up oxidation significantly. Move your oil to a closed cabinet away from all appliances.
What is the best container to store olive oil in?
Dark glass is the best choice. It is chemically inert, blocks UV light, and does not leach compounds into the oil. Metal tins are also good. Avoid clear glass and plastic entirely.
