Producing a high-quality olive oil is only half the job — getting it to consumers in the right packaging matters just as much. That's because olive oil is a natural product that's easily affected by outside factors like light, air, and heat.
For that reason, the packaging an olive oil is sold in plays a major role in preserving its freshness, aroma, and overall quality.
So what actually separates glass bottles, tin containers, and PET plastic bottles? Which one suits which use case? Let's break it down.
Why Does Packaging Choice Matter for Olive Oil?
From the moment it's produced, extra virgin olive oil begins changing on a sensory level as it comes into contact with oxygen, light, and heat over time.
The right packaging minimizes these outside factors as much as possible, helping preserve the oil's quality. That's why, when buying olive oil, it's not just the oil itself that deserves attention — the packaging it comes in matters too.
Why Is Glass the Preferred Choice for Olive Oil?
Glass is one of the most popular packaging choices for olive oil, and for good reason.
Glass doesn't react chemically with olive oil, which helps preserve the oil's natural composition. Opaque, dark-tinted glass in particular reduces the oil's exposure to light, helping it stay better preserved over time. That's exactly why dark glass bottles are so commonly used for premium olive oils.
The advantages of glass bottles:
- Helps preserve the olive oil's natural composition
- Doesn't transfer any odor or taste to the oil
- A recyclable packaging material
- Dark-tinted glass in particular offers strong protection against light
- Delivers an elegant, aesthetically pleasing presentation
The Advantages of Tin Packaging for Olive Oil
Tin containers are especially popular for larger-volume olive oil products.
Because they block out light entirely, tin helps protect the oil's quality. Tin containers are also lightweight and easy to transport, which adds to their appeal.
For households that go through large quantities of olive oil, tin packaging is a genuinely practical option.
The advantages of tin packaging:
- Blocks out light completely
- Well suited to large-volume products
- Sturdy construction makes it easy to transport
- A recyclable packaging material
Is PET (Plastic) Bottling Used for Olive Oil?
Olive oil is a chemically active liquid with acidic and solvent-like properties. When left sitting in plastic (PET) bottles for extended periods, it can absorb chemical compounds present in the plastic itself. In other words, plastic can compromise the oil's purity and even pose a risk to health.
On top of that, plastic packaging is more permeable to light and oxygen. Over time, this causes the oil to oxidize and lose quality.
For these reasons, we don't recommend plastic (PET) packaging for olive oil.
Why Does Dark Glass Matter So Much?
One of olive oil's biggest enemies is direct sunlight.
Oils exposed to light for extended periods, in particular, can undergo noticeable sensory changes over time. That's why dark glass bottles are so effective — they reduce the oil's exposure to light and help preserve its freshness.
This is exactly why dark-tinted glass bottles remain one of the most preferred packaging options for extra virgin olive oil.
Don't Forget to Store Your Olive Oil Correctly!
No matter how good the packaging is, proper storage conditions matter just as much for preserving your olive oil's freshness. We recommend keeping your olive oil out of direct sunlight, in a cool, dry place.
Tightly sealing the bottle or tin after every use helps limit the oil's exposure to air. Keeping olive oil away from stoves, ovens, and other heat sources also goes a long way toward preserving its quality.
In short, regardless of which packaging it comes in, storing your olive oil somewhere cool, dry, and free from light will help it hold onto its natural aroma and sensory qualities for much longer.
