The olive oil squeeze bottle trend—and why we’re not following it.

The olive oil squeeze bottle format exploded fast, and for understandable reasons: one brand proved there was real, pent-up appetite for a more approachable olive oil experience.

Squeeze bottles are everywhere. Walk into any independent food shop, scroll through an influencer's kitchen tour, or check the shelves of your local grocer, and there they are—soft-sided, nozzle-topped, the whole thing quietly implying that olive oil has been reinvented. 

This piece isn't a case against doing things differently. It's a case for asking whether doing things differently is actually serving the oil. Because the answer is more nuanced than 'plastic bad, glass good.' And that nuance matters if you care about what you're actually consuming.

How the olive oil squeeze bottle took over

One brand started it. Everyone else copied.

The squeeze bottle's moment in olive oil happened quickly enough that the retail move barely had time to breathe before it was replicated across the market. One brand (Graza in the US market, most visibly) made the case that playfully packaged olive oil could be fun, approachable, and format-forward. They were right, and the market responded.

But 'the market responded' is a polite way of saying that every brand watching from the sidelines immediately began sourcing its own squeeze bottles. Within a year, the format had migrated from a brand-defining idea to a cheap, commodity packaging choice. A problem for a speciality product that often already gets wrongly commoditised.

It's worth saying, too, that the squeeze bottle itself isn't a new invention. Chefs have decanted oil into plastic squeezers for years—they're fast, precise, and easy to control on the line. But a professional kitchen turns a bottle over in days, not months; the oil never has time to degrade. 

What Graza did, essentially, was take a format that worked brilliantly in a high-turnover kitchen and bring it to a retail shelf, where the same bottle might sit for months before it's even opened. The marketing was sharp, the design was sharper, and the retail move was genuinely new. But the format was borrowed from a context with completely different conditions—and that's where the preservation question actually starts.

So let's untangle the packaging problem.

Why the squeeze bottle filled a gap glass left open

Glass was already under pressure before the squeeze bottle arrived. The UK's packaging Extended Producer Responsibility (pEPR) scheme, introduced in 2025, calculates fees by weight, which hits glass disproportionately hard compared to plastic or metal. Transport fragility means it also requires significantly more protective secondary packaging. These costs don't always show up on the label, but they shape the decisions brands make.

Brands were already looking for alternatives. When a format came along that was lighter, cheaper, easier to ship, and—crucially—had already been proven to work commercially, the decision wasn't difficult. The olive oil squeeze bottle didn't just win on aesthetics. It arrived at exactly the right moment. The question is whether the format that filled that gap is actually good for the oil inside.

What olive oil actually needs from its packaging

Before comparing formats, though, it helps to understand what a genuinely good extra virgin olive oil (EVOO) requires in order to stay that way. The difference between fresh, properly-stored EVOO and a bottle that’s been sitting in ambient light for six months is not subtle: it’s the difference between a food with meaningful, well-documented health benefits and something that’s nutritionally closer to a standard cooking fat.

What makes extra virgin olive oil worth protecting

A genuinely good extra virgin olive oil is a living thing. It has flavour, aroma, and health properties that start degrading from the moment it's made—and that packaging either preserves or destroys.

The polyphenols are what give high-quality oil that distinctive peppery finish. They're also behind most of the serious health research on why good olive oil matters, including oleocanthal, which works in a similar way to ibuprofen at a biochemical level. Poor packaging destroys these compounds more quickly, along with the fresh aromas and flavours that tell you the oil is worth what you paid for it.

The three things that degrade it: oxygen, light, and time

Olive oil starts degrading the moment it leaves the mill, and the culprits are always the same: oxygen, light, and time. Together they dull the flavour, strip the aroma, and gradually break down everything that made the oil worth buying in the first place. The supply chain from harvest to your kitchen can stretch months (sometimes well over a year for commodity oil) and the packaging has to hold up across all of it.

Which means the choice of container isn't aesthetic. It's functional. And not all formats do the job equally well, which is where the squeeze bottle conversation gets interesting.

Not all plastic is the same

So let’s first talk about plastic. This is where most conversations about olive oil packaging go wrong. ‘Plastic’ gets treated as a single category—bad, permeable, environmentally suspect. But the materials science here matters, because the difference between standard mono-layer PET and a properly engineered multi-layer (often found in bag-in-box or pouches) is not cosmetic. It's the difference between a container that actively allows the oil to degrade and one that genuinely protects it.

Why mono-layer plastic fails olive oil

Standard PET (the plastic used in most olive oil squeeze bottles) is a single-layer, gas-permeable polymer. Oxygen migrates in through the walls; volatile aromatic compounds (the ones responsible for the fresh, grassy, spicy notes in good oil) migrate out. The result is predictable: accelerated oxidation, flavour loss, and measurable decline in polyphenol content over a timescale that matters in a normal supply chain.

Studies show losses of more than 50% of total phenolic content, with an increase in peroxide values by 25% within 3-6 months. That’s substantial.

UC Davis Olive Center research on packaging and quality degradation supports what any serious producer who has tested across formats will tell you: the oil in a standard plastic PET container deteriorates faster than the same oil in dark glass, often significantly so within six months. For an oil that might sit in a warehouse, on a shipping container, and on a shelf before it reaches you, that’s a problem.

The squeeze bottle trend, in its current form, largely relies on mono-layer PET. From a quality preservation standpoint, it’s not a good container for serious olive oil.

Why multi-layer pouches are different

A multi-layer pouch is a genuinely different material. It combines layers of different polymers (typically including EVOH—ethylene vinyl alcohol), which acts as an oxygen barrier) to create a structure that is functionally much closer to glass in terms of permeability. The layers are engineered specifically to prevent gas exchange, and independent research backs this up: studies comparing bag-in-box multi-layer pouches to dark glass bottles have found comparable shelf life for extra virgin olive oil across both formats.

We’ve tested this directly. We re-tested oil from our glass bottles and our multi-layer pouches at the two-year mark to see how quality held up, and the difference was minimal. That’s not what you’d expect from packaging that ‘is just plastic.’ It reflects the genuine engineering difference between a barrier pouch and a standard polymer container.

We also tested bioplastics—seaweed-based packaging, which is a pretty appealing idea from a sustainability standpoint. The result, however, was a significant drop in quality within just a few months. The barrier properties weren’t there, regardless of the ecological credentials.

It’s a reminder that we’re still actively looking for formats that deliver on both, and that we genuinely welcome insights from anyone working on this.

Why dark glass is still the benchmark

Opaque glass or ceramic remains the best-understood, most reliable format for long-term quality preservation in olive oil. Glass is chemically inert: it doesn’t interact with the oil, doesn’t off-gas, doesn’t allow oxygen migration. A properly sealed dark glass bottle reliably maintains extra virgin status for up to 24 months when stored correctly.

But the limitation of glass isn’t quality. It’s everything else: weight, fragility, the carbon cost of transport, the secondary packaging required to prevent breakage. These are real trade-offs, and we don’t pretend otherwise. But as a quality benchmark, glass sets the standard against which other formats should be evaluated.

The sustainability case is more complicated than it looks

The instinct that ‘glass = sustainable, plastic = bad’ is understandable but doesn’t survive much scrutiny. The full lifecycle picture is considerably more complicated, and brands that don’t acknowledge this complexity are, at minimum, oversimplifying.

Glass isn’t automatically the green choice

We've already seen how the economics of glass opened the door to the squeeze bottle. But the sustainability case against glass goes beyond cost. It's also about carbon.

Glass is heavy. For every shipment of olive oil in glass bottles, a significant proportion of what you’re transporting is the container itself. The carbon footprint of that transport—from producer to warehouse to retailer—is not trivial. Add the fragility problem: glass requires substantial secondary packaging (cardboard, foam, dividers) to survive transit, all of which has its own footprint.

We’ve modelled this directly for our own operation with a carbon agency. Our multi-layer pouches generate approximately 15 times less carbon than our glass bottles, and that’s before accounting for the additional protective packaging that glass requires in transit. That’s a meaningful number, and we think it’s important to be transparent about it.

Beyond carbon, there's a recycling reality that often goes unsaid. Glass is infinitely recyclable in theory, and the UK does better than most at around 75%. But 'recycled' covers a lot of ground—a significant share of collected glass is downcycled into aggregate for roads and building materials rather than remelted back into new bottles, which is the truly circular outcome. And globally, the picture varies hugely: contamination during collection, patchy infrastructure, and the cost of transporting such a heavy material mean plenty of glass still ends up in landfill depending on where you are.

What happens to multi-layer pouches at end of life

There’s a trade-off, and we’ll be straightforward about it: multi-layer pouches can’t go into standard household recycling. The laminated structure that makes them effective as oxygen barriers is also what makes them difficult to process at end of life. They require specialist recycling infrastructure.

With that in mind, we have a refillable packaging programme through which we cover return shipping on your empties and put the plastic back into circulation. We also have our own ceramic bottle, designed to be refilled rather than replaced. That said, we won’t pretend the end-of-life question doesn’t exist for those pouches which aren’t sent back to us. It does, and it’s a genuine limitation of the format—one that the industry, including us, needs to keep working on.

The honest position on sustainability in olive oil packaging is: there is no perfect format. 

Glass wins on recyclability and end-of-life simplicity but loses on transport carbon. 

Multi-layer pouches win on transport carbon and quality preservation but lose on household recycling. 

Standard mono-plastic PET is cheap, recyclable, and lightweight but fails on quality. 

Every choice involves trade-offs, and brands that present one format as unambiguously sustainable are leaving something out. What is clear, however, is which formats win when quality—and quality preservation—is the priority. Standard PET isn’t one of them.

A contradiction worth naming

There's a tension running through all of this. Shoppers consistently say they want less plastic, and yet when something well-designed shows up in a plastic bottle, they buy it anyway. Graza remains the clearest example—launched in 2022, with $48 million in sales by the end of 2024 and still growing fast. The gap between what people say they want and what they actually reach for is real, and it's worth sitting with.

What to look for when you buy

So what do you as a shopper look for when buying truly good extra virgin? A good bottle of olive oil usually tells you more than you think—if you know what to ask. When you pick up a bottle (in any format), there are three main questions worth asking:

1. What is the format, and what does it actually do for the oil? A squeeze bottle might be convenient, but does the brand explain how it protects the oil from oxygen and light, or just how easy it is to use? A brand that has thought seriously about quality preservation will usually tell you about it.

2. How long has this oil likely been in the supply chain? Harvest typically happens in October and November in the Northern Hemisphere. If you’re buying in summer and the bottle doesn’t carry a harvest date, that’s worth noting. Time is always working against the oil, and packaging that seemed adequate at bottling may not be adequate twelve months later.

3. Does the brand back up its quality claims? Polyphenol content, acidity levels, harvest date—a brand that's genuinely confident in its oil will share the numbers. If the label leads with lifestyle and the small print has nothing to verify it, that's a red flag. Identifying authentic extra virgin olive oil requires a little extra sleuthing, but it's worth it.

4. Does the brand distinguish between format innovation and quality innovation? There’s a difference between packaging that makes oil more convenient to use and packaging that makes it better preserved. The olive oil squeeze bottle trend has largely been the former dressed up as the latter.

Bottom line: good oil deserves good packaging

Squeeze bottles aren't going anywhere anytime soon. Some of the oil inside those bottles could have been excellent, carefully sourced, and properly handled across a supply chain that takes quality seriously. We genuinely hope so, because more people engaged with good olive oil is good for everyone. 

But the format itself is not a proxy for quality, and the speed with which it has proliferated across the market suggests that for many brands, it never was. It was a format that worked commercially, and on TikTok, so it got copied.

We're not done looking for better solutions either. Packaging that does right by the oil and by the planet is worth pursuing. If you're working in this space, we'd genuinely welcome the conversation.

So ask what's in the bottle. Ask how it was packaged. Ask how long it's been in the supply chain. Ask whether the brand can tell you something meaningful about polyphenol content or harvest date or sensory analysis. If they can, you're probably dealing with someone who cares. If the answer is just a well-designed label and a convenient pour, then keep looking.
