Box vs. bottle: the real price per glass (spoiler: the box wins)
For equivalent quality, wine in a BIB is consistently cheaper per glass than in a bottle. A 5L BIB at €35 costs about €1.10 per glass. A bottle from the same winemaker at €12? €2 per glass. The difference comes from the packaging, transport, and distribution margins — not the wine itself.
Why compare by the glass, not by the bottle
Comparing a 5L BIB at €35 to an €8 bottle makes no sense — it's not the same volume. The only honest comparison is the price per glass (or per liter) for wine of the same quality.
A standard glass = 12.5 cl. From there, the calculation is simple:
3L BIB at €24 → 24 glasses → €1.00/glass
5L BIB at €35 → 40 glasses → €0.88/glass
75cl bottle at €10 → 6 glasses → €1.67/glass
75cl bottle at €15 → 6 glasses → €2.50/glass
For equivalent wine, the BIB cuts the price per glass by 1.5 to 2 times — with no compromise on quality.
Where does this difference come from?
Not from the wine. The wine in a 5L BIB and the wine in the bottle from the same winemaker is often exactly the same juice. What changes is everything surrounding the wine.
Glass: A glass bottle costs between €0.80 and €2.50 depending on the model. For 6 glasses of wine, that is a considerable packaging cost. A BIB pouch costs a fraction of that.
Transport: A pallet of bottled wine actually transports as much glass as wine. In a BIB, the packaging weighs almost nothing — so more wine per truck, and less logistical cost passed on to the final price.
Distribution: A bottle often passes through an importer, a distributor, and a wine shop. Each intermediary takes their margin. BIBs, often sold through shorter supply chains, have a leaner distribution chain.
Same winemaker, same wine: the price per liter test
Some winemakers in our selection offer their vintages in both bottle and BIB. When comparing the price per liter, the difference generally hovers between 15% and 30% in favor of the BIB.
It’s not because the wine in a BIB is "worse." It’s because the winemaker passes the savings from packaging and transport on to the sale price — and you benefit directly.
A winemaker who puts their wine in a BIB is not cheapening their vintage. They are choosing a more economical format for everyone — including the planet. Our article BIB vs. Bottle: The Real Carbon Footprint quantifies the environmental difference.
And in a restaurant, what is the real cost?
In a restaurant, a glass of wine sold for €6-8 often comes from a bottle bought for around €5-8 (the first glass "pays back" the bottle, the other glasses are pure profit). With a BIB, the restaurateur buys for less per liter, eliminates loss by the glass between services, and can offer better margins or better wines at the same price.
That is why more and more bars and restaurants are switching to BIB — not to cut corners on quality, but to optimize it. We discuss this in more detail in our Pro Access section.
Is a "cubi" (bag-in-box) necessarily low-end wine?
No — and that is arguably the most persistent prejudice. The BIB format has no impact on wine quality. Renowned organic, natural, and biodynamic winemakers package their best vintages in BIB — because the airtight pouch protects the wine from oxidation better than an opened bottle, and because the format aligns with their values.
The question of high-end bag-in-box deserves an entire article — we answer it in Does high-end bag-in-box exist?.
And to understand how to precisely calculate your cost per glass based on the price of the BIB, everything is in our guide how much does a glass of wine in a cubi cost.
Frequently Asked Questions
Is wine in a cubi really cheaper than in a bottle?
For equivalent quality, yes — consistently. The difference comes from packaging (glass is expensive), transport (BIB is much lighter), and the distribution chain. For the same winemaker's wine, the BIB averages 15 to 30% cheaper per liter than the bottle.
How to calculate the price per glass of a BIB?
Divide the price of the BIB by the number of glasses: one glass = 12.5 cl, so a 3L = 24 glasses, a 5L = 40 glasses. A 5L BIB at €35 comes to €0.88 per glass. For a quick calculation by volume, consult our guide how much does a glass of wine in a cubi cost.
