How should the bottle be stored after opening, and how long does it typically stay fresh?

To keep the oil fresh and prevent it from going rancid, store the bottle in a cool, dark place after opening, such as a pantry or cupboard away from the stove or direct sunlight. Refrigeration is also a good option, which can help extend its shelf life. The cold may cause the oil to become cloudy or thicker, but this is a natural reaction and does not affect quality; it will return to its normal consistency when brought back to room temperature.

While exact shelf life depends on storage conditions, a typical guideline for unrefined oils is to consume the opened bottle within 3-6 months for best quality. Always check the 'best before' date on the bottle. You can tell if the oil has spoiled by smelling it – a sharp, bitter, or 'off' smell indicates it's no longer good to use. Tightly closing the cap after each use helps minimize exposure to air and light.
