If you run a restaurant, hotel, bar or catering business, you already know the challenge: keeping quality wine on the table at a price that makes sense for your margins — without sacrificing the experience your guests expect.
Bag-in-box wine has quietly become one of the smartest purchasing decisions in the HoReCa sector. And with an anonymous, custom-labelled solution, it goes one step further: you serve your house wine, under your brand, with no one knowing where it comes from.
Why restaurants and hotels are switching to bag-in-box wine
The shift towards bag-in-box in professional settings is not a trend — it is a business decision driven by numbers.
Traditional bottles are beautiful on a wine list, but for house wine service they come with real operational costs: glass waste, storage space, breakage risk and — most critically — oxidation. An opened bottle of wine is at its best for 24 to 72 hours. After that, quality drops and margins shrink.
Bag-in-box eliminates most of these problems at once.
Cost per glass: the real difference
Here is a simple comparison worth doing with your supplier:
| Format | Approximate glasses (150ml) | Equivalent bottles |
|---|---|---|
| 2L BIB | ~13 | ~2.6 bottles |
| 3L BIB | ~20 | ~4 bottles |
| 5L BIB | ~33 | ~6.6 bottles |
| 10L BIB | ~66 | ~13 bottles |
| 20L BIB | ~133 | ~26 bottles |
When you buy in bulk format, the cost per litre drops significantly compared to individual bottles. For a busy restaurant serving house wine by the glass, that difference compounds quickly across hundreds of covers per week.
Fresh wine, every glass: how the bag-in-box system works
The bag-in-box format uses a sealed inner bag with a one-way valve. When wine is dispensed, air never enters the bag — the bag simply collapses around the remaining wine. This means:
- No oxidation after opening
- Wine stays fresh for up to 6 weeks once tapped
- No need to finish a box within days
- Consistent quality from the first glass to the last
For bars and restaurants with moderate wine rotation, this is a genuine operational advantage. No more pouring away opened bottles at the end of service.
The anonymous bag-in-box: your house wine, your brand
This is where the Interbrosa solution goes beyond standard bulk wine supply.
Our bag-in-box wines come in a clean, neutral white box with no producer branding. You apply your own custom sticker label — your restaurant name, your logo, your design — and the result is a professional house wine that is entirely yours.
What “anonymous” means for your business
When a guest orders your house wine, they are ordering your wine. There is no reference to the producer, the region or the price point on the packaging. This gives you:
- Higher perceived value — guests associate the wine with your brand, not a supermarket shelf
- Supplier discretion — your purchasing decisions stay private
- Pricing flexibility — you set the glass price without the customer cross-referencing the producer online
- Brand consistency — the label matches your restaurant’s visual identity
It is the same model used by some of the best restaurants in the world for their house pours. Now accessible at any scale.
How the custom sticker label works
The process is straightforward:
- Choose your wine type and format from our BIB range
- Send us your label design — or we can advise on design partners
- We supply the neutral white box, you apply your sticker
- Your house wine is ready to serve
No minimum design fees. No complicated customisation process. Just your wine, your way.
Our full bag-in-box range for HoReCa
At Interbrosa we offer a complete selection of bag-in-box wines designed for professional use, available in 2L, 3L, 5L, 10L and 20L formats. All products are available in anonymous white-box format with custom sticker labelling.
Still wines: red, white and rosé
Our core BIB range covers the three pillars of any house wine programme. Whether your guests lean towards a fresh white, a food-friendly red or a versatile rosé, we have a format and style to match your menu and your clientele.
Organic bag-in-box wine
Sustainability is no longer a niche. Hotels and restaurants with green certifications, farm-to-table positioning or environmentally conscious guests are increasingly seeking organic options across their beverage programme.
Our organic bag-in-box wines — including certified organic red, white and rosé — bring the same quality and freshness of our standard range with full organic certification. Available in the same anonymous format, they allow you to offer an organic house wine under your own label without the premium price point of bottled organic wine.
A strong choice for Scandinavian and Northern European markets where organic credentials matter to both buyers and consumers.
Sangria in bag-in-box
Sangria is one of the most ordered drinks in tourist-facing restaurants, beach clubs, hotel bars and summer terraces across Europe and beyond.
Our bag-in-box sangria removes the preparation time and consistency issues of making it in-house. Ready to serve, consistently flavoured, and available in bulk formats that make sense for high-volume service. No batch mixing, no leftover fruit, no waste.
Whether you are running a poolside bar in the Balearics or a Spanish-themed restaurant in Scandinavia, BIB sangria is a practical solution that keeps quality consistent across every glass.
Glögg in bag-in-box
For venues operating in Northern European markets — particularly Scandinavia and the Baltics — glögg is a seasonal staple with serious commercial potential.
Our Vinterholm Glögg in bag-in-box format is purpose-built for HoReCa service during the Christmas and winter season. Heated and served by the mug, it is a high-margin product with a loyal following in markets like Norway, Sweden, Denmark, Finland and the Baltic states.
Available in bulk BIB format, it eliminates the need to source individual bottles during your busiest seasonal period and keeps your service consistent from November through January.
Is bag-in-box wine good quality? Debunking the myths
The idea that bag-in-box means low quality is outdated — and the awards prove it.
Our Detunda Organic 3L bag-in-box won three gold medals at the Gilbert & Gaillard International Challenge 2025, one of the most respected wine competitions in the world. This is not the exception. Modern winemaking in bag-in-box format produces wines that hold up to blind tastings against bottled equivalents.
The BIB format does not compromise the wine. It protects it.
What it does eliminate is the cost and waste associated with glass packaging — which is precisely why professional buyers across Europe have made it a core part of their purchasing strategy.
