What should I know about storing this oil properly?

Like any cold-pressed, unrefined plant oil, this milk thistle oil is sensitive to light, heat, and air, which can affect its flavour and nutritional quality over time. To best preserve it, store the bottle in a cool, dark place such as a pantry or cupboard, away from direct sunlight and sources of heat like the stove. After each use, tightly close the cap to minimise exposure to oxygen.

You may also consider refrigerating it, especially in warmer climates. Chilling can cause the oil to become cloudy or solidify slightly; this is natural and doesn't harm the product – its texture will return to normal after being brought to room temperature. Always check for any unusual or rancid odour before use. Use the oil sensibly within a balanced menu.
