How much does a glass of boxed wine cost?
A glass of boxed wine (12.5 cl) costs between €0.60 and €1.50 depending on the price of the BIB. A 5L BIB at €30 comes to €0.75 per glass. A 3L BIB at €22 comes to €0.92 per glass. For a bottle equivalent at €10, it's €1.67 per glass — or twice as much.
The basis of the calculation: 12.5 cl per glass
A standard glass of wine = 12.5 cl. This is the universal reference measurement — in restaurants, at the wine merchant's, and in pairing guides. From there, the calculation is a simple division:
Price per glass = Price of the BIB ÷ Number of glasses
And the number of glasses per volume:
3L BIB → 24 glasses
5L BIB → 40 glasses
10L BIB → 80 glasses
The complete table: price per glass according to the BIB price
For a 3L BIB:
€20 → €0.83/glass
€25 → €1.04/glass
€30 → €1.25/glass
For a 5L BIB:
€25 → €0.63/glass
€35 → €0.88/glass
€45 → €1.13/glass
For a 10L BIB:
€55 → €0.69/glass
€70 → €0.88/glass
€90 → €1.13/glass
For comparison: an €8 bottle comes to €1.33/glass, at €12 it's €2.00/glass, and at €15 it's €2.50/glass. The advantage of the BIB is systematic for equivalent quality.
Why BIB is cheaper by the glass
It's not because the wine is of lower quality. It's because the BIB costs much less to produce and transport than a glass bottle. A glass bottle, depending on its model, costs between €0.80 and €2.50 to manufacture — before even putting the wine in it. The bag in a BIB costs a fraction of that. The winemaker passes this saving on to the selling price.

Concrete examples for your daily life
An aperitif for 6 people (2 glasses each = 12 glasses):
Using a 3L BIB at €24: 12 glasses = €12.00 worth of wine consumed
Using €10 bottles: 2 bottles = €20.00
Savings: €8 for exactly the same experience.
A dinner for 4 people (3 glasses each = 12 glasses):
Using a 5L BIB at €32: 12 glasses = €9.60 worth of wine consumed
Using €11 bottles: 2 bottles = €22.00
Savings: €12.40.
And in both cases, the rest of the BIB keeps for 4 to 6 weeks — no waste, no opened bottle turning bad in the fridge.
The real question: same quality?
Yes — and this is the most important point. The BIB format has no impact on the quality of the wine. Organic, natural, and biodynamic winemakers selected for their expertise package their vintages in BIB — because the airtight bag protects the wine better, and because the format aligns with their values.

Frequently asked questions
What is the average price of a glass of wine in a BIB?
Between €0.75 and €1.25 per glass for most quality BIBs. This is 40 to 60% cheaper than an equivalent bottle in terms of price per glass.
Is the price per glass better in 5L than in 3L?
Generally yes, slightly — larger formats are a bit more economical per liter. But the difference is often marginal. Choose the size suited to your consumption first; the price per liter is secondary.
