Why we bottle our oils in amber glass

If you've bought from us, you'll have noticed the bottles. Dark amber glass, black caps. It would be cheaper and lighter to use clear plastic, so it's fair to ask why we don't.

The short answer is that oils go off, and the bottle is the best protection they have.

What actually spoils an oil

Three things: light, heat and air. Over time they break the oil down, and it goes rancid. You'll know it when it happens because the oil smells flat or a bit like old crayons. Cold-pressed oils are especially sensitive because nothing has been added to preserve them.

Amber glass blocks most of the light that does the damage. That alone makes a big difference to how long an oil stays fresh.

Why not plastic?

Plastic can let a small amount of air through over time, and some oils don't sit well with certain plastics. Glass doesn't do either. It also doesn't hold onto smells, and it can be washed and reused.

Getting the most from your bottle

• Keep it somewhere cool and out of direct sun, like a cupboard or drawer, not a sunny bathroom windowsill.
• Close the cap properly after each use.
• Try to use it within about 12 months of opening.

When a bottle is empty, rinse it out and reuse it for travel-size refills, or recycle it. We also sell empty amber bottles if you want to decant your own.
