How to Store Cold Pressed Oil at Home So It Stays Fresh

Cold pressed oils are made without high heat or chemical refining, so they keep more of their natural aroma and flavour. That also means they are a little more sensitive to how you store them. A few simple habits keep your oil tasting good until the last spoon.

What Spoils Oil?

Three things speed up spoilage:

Heat: warm kitchens and storage near the stove
Light: direct sunlight or bright shelves
Air: bottles left open or half empty for months

Keep these three away from your bottle and you are most of the way there.

Choose the Right Container

Dark glass or food-grade steel protects oil from light.
Tight lids keep air out.
If you buy in a large can or jar, decant into a smaller bottle for daily use and keep the rest sealed.
Wash and dry bottles completely before refilling. Water spoils oil.

Where to Keep It

Store oil in a cool, dark cupboard away from the stove, oven and any window. A shelf beside the gas stove is convenient but warm. Keep a small bottle there for daily cooking and the main bottle elsewhere.

Do not refrigerate unless the producer advises it. Some oils turn cloudy or solid in the cold, which is normal but inconvenient.

How Long Does It Last?

Shelf life depends on the oil, how it was packed and how it is kept. Check the date on your bottle and follow the producer's guidance. As a general rule:

Buy sizes you will finish within a few months of opening.
Use clean, dry spoons rather than pouring back used oil.
Close the lid right after each use.

Is Sediment Normal?

Cold pressed and unfiltered oils can show a little natural sediment at the bottom. This is usually fine. Shake gently before use if you want an even flavour, or let it settle and pour from the top. Do not confuse it with mould or an off smell.

Cloudy in Winter?

Some oils, such as coconut and sesame, thicken or turn cloudy in cool weather. Set the bottle in a bowl of warm water for a few minutes and it clears. Avoid microwaving the bottle.

How to Tell If Oil Has Gone Off

Trust your senses:

Smell: a sharp, sour, paint-like or crayon-like smell suggests rancidity.
Taste: a bitter or unpleasant flavour.
Appearance: mould, an unusual film or an unpleasant colour change.

When in doubt, do not use it.

Do Not Reuse Frying Oil Many Times

Repeated heating changes both taste and quality. Strain used oil, store it separately and discard it after a limited number of uses, or when it smells or looks burnt.
