1. Wine storage essentials

Wine is highly sensitive to environmental conditions. Stability matters more than hitting an exact number a consistent environment ensures wine develops as intended over time. Modern wine cooling solutions have evolved from basic storage units into precision-engineered, kitchen-integrated systems.

The four main factors that affect wine quality in storage are temperature stability, vibration, humidity and UV light exposure. Premium wine coolers address all four. A standard kitchen refrigerator does not: it runs too cold, vibrates too much and cycles temperature too aggressively.

Even fluctuations of 3–5°C can irreversibly affect aroma, structure and aging potential. Consistent temperature over time is the single most important factor in wine preservation.

🌡 Temperature stability The most critical factor. Premium coolers maintain consistent internal climate rather than just reaching a target temperature.

〰 Vibration control Excessive vibration disturbs sediment and accelerates chemical reactions. Professional wine coolers minimise vibration by design.

💧 Humidity 50–80% relative humidity keeps corks in condition. Too dry and corks shrink; too humid and mould becomes a risk.

🚫 UV protection UV exposure degrades wine over time. Smoked or UV-filtered glass doors protect the collection without sacrificing aesthetics.

2. Built-in vs fully integrated wine coolers

Not all wine coolers are designed for the same installation context. Understanding the difference between built-in and fully integrated solutions is essential for correct specification.

Feature	Built-in	Fully integrated
Appearance	Ventillation plinth is visible	Seamless fit
Ventilation	Requires cabinet planning	Integrated, no extra vents needed
Installation	Front and rear vents is a must	Plug & play
Who it's for	Home users, most kitchen environments	Kitchen designers, architect-led projects
Best for	Most kitchen environments	Premium & architect-designed kitchens

Dunavox tip: Fully integrated models use integrated ventilation technology, no additional cabinet ventilation openings are required.

3. Wine storage & serving temperatures

Different wines require different storage and serving conditions. Multi-zone wine coolers allow multiple wine types to be stored simultaneously at their optimal temperatures. For mixed collections where a single zone is preferred, 10–14°C is the universally recommended compromise.

Note: In the majority of Dunavox models the upper zone is the cooler zone and the lower zone is the warmer zone. The exceptions are the DXB-26.69, DXJ-26.69 and DAUF-32.78, where the zone assignment is reversed.

Wine type	Storage temp.	Serving temp.	Zone
Full-bodied red	14–18°C	16–18°C	Lower
Light red	12–14°C	13–15°C	Lower
White wine	8–12°C	8–10°C	Upper
Rosé	8–12°C	8–10°C	Upper
Sparkling / champagne	10–12°C	6–8°C	Upper
Mixed / long-term storage	10–14°C	—	Single zone

5. The 88 cm undercounter format

Dunavox was among the first to bring 88 cm undercounter wine coolers to the professional kitchen market — a format developed specifically in response to rising worktop heights in modern kitchen design. Standard undercounter appliances (82 cm) no longer align with contemporary furniture systems, leaving gaps and compromising the visual integrity of the kitchen.

The 88 cm format ensures correct alignment beneath modern worktops, eliminates filler panels, improves ergonomics and increases usable interior space — all without structural modifications to the kitchen.

— Designed for modern kitchen heights of 95-100cm worktops

— Eliminates filler panels and visual gaps in the plinth area

— Providing greater flexibility in bottle arrangement due to the expanded interior space, including support for champagne-sized bottles*

— Improved ergonomics, easier bottle access at working height

— Compatible with contemporary furniture systems across Europe

— Available in both built-in and fully integrated configurations

* Champagne-sized bottle support applies to the DAUF-41.146. Please refer to individual product specifications for full bottle configuration details.

Why does manufacturer-led development matter for kitchen projects?

For professional kitchen studios and large projects, product consistency is critical. Manufacturer-led development ensures stable product lines, predictable lead times and guaranteed dimensional accuracy — all essential when fitting wine coolers into bespoke furniture systems where tolerance is tight.

Built-in vs fully integrated

What is the difference between a built-in and a fully integrated wine cooler?

Main difference is the installation method. Built-in installation requires front and rear ventillation plinths in the column. Fully-integrated models comes with a self-ventilated integrated ventillation system that makes the installation easy, plug&play solution. No preparation is needed for the columns and gives the freedom of an undercounter installation as well thanks to the integrated ventilation system.

Do fully integrated wine coolers need ventilation planning?

No — Dunavox fully integrated wine coolers use built-in ventilation technology that eliminates the need for additional cabinet ventilation openings or plinth cutouts. This is what makes them a true plug-and-play solution. Built-in models do require ventilation planning and unobstructed airflow paths.

Which type is right for my project — built-in or fully integrated?

For most domestic kitchen environments, a built-in or undercounter wine cooler is the most practical choice. For high-specification, architect-designed, or premium kitchen projects where seamless appearance is a priority, a fully integrated model is the correct specification. Kitchen studios and professional project teams typically specify fully integrated models for premium builds.

88 cm undercounter format & sizing

What is an 88 cm undercounter wine cooler and why does it exist?

The 88 cm undercounter format was developed to align with the rising worktop heights found in modern kitchen design (typically 95-100cm). Standard undercounter appliances at 82 cm leave a visible gap beneath contemporary worktops, requiring filler panels that compromise the kitchen's visual integrity. The 88 cm format addresses this problem. Dunavox has been among the leaders in bringing this format to the professional kitchen market.

What are the practical advantages of the 88 cm format over 82 cm?

The 88 cm format provides correct alignment with modern worktops (no filler panels required), greater flexibility in bottle arrangement due to the expanded interior space, improved ergonomics with better bottle access at working height, and compatibility with contemporary European furniture systems. It is available in both built-in and fully integrated configurations. Please refer to individual product specifications for bottle capacity and configuration details.

What size wine cooler should I choose?

The right choice depends on your collection size, available space and kitchen design. Narrow undercounter units (15–30 cm wide) suit accent installations or tight spaces beneath the worktop. Standard undercounter modules (40-60 cm wide) align with standard cabinet widths and offer the most versatile integration. For kitchens with modern worktop heights of 95-100cm, the 88 cm undercounter format is the recommended choice — it eliminates filler panels and aligns cleanly with contemporary furniture. Full-height cabinets (178–185 cm) offer maximum capacity for dedicated wine rooms or showroom installations.

What does bottle capacity really mean — and why does it vary?

Quoted bottle capacity is measured using standard Bordeaux bottles under standardised conditions. Actual usable capacity varies depending on bottle shape (Burgundy, Champagne and magnum bottles are wider and taller), shelf configuration and whether the cooler is also used as a serving unit with mixed bottle sizes. Capacity figures are best treated as a comparative guide rather than an absolute guarantee.

Installation

What documentation does Dunavox provide for professional installations?

Dunavox provides full installation drawings, dimensional schematics, ventilation requirements and 3D DWG files compatible with standard professional kitchen design software. This documentation is available for all models and supports accurate furniture planning and specification at every project stage. Electrical requirements are indicated on the product label.

Are Dunavox wine coolers suitable for large-scale kitchen projects?

Yes. Dunavox's stable, manufacturer-led product lines support multi-unit installations with consistent dimensions and specifications across production runs. This makes it straightforward to specify the same model across multiple units in a development or hospitality project, with confidence that replacement units will match the original specification.

Does the wine cooler need a dedicated power circuit?

A dedicated power circuit is recommended for all professional and built-in wine cooler installations. This ensures stable electrical supply, avoids voltage fluctuations caused by shared circuits, and protects the compressor system over the long term. Always refer to the product label for exact electrical requirements.

Why does the wine cooler need to rest for 24 hours before use?

During transport, refrigerant can shift within the compressor system. Allowing the appliance to stand upright for at least 24 hours before first use lets the refrigerant settle back into its correct position, preventing compressor damage when the unit is first switched on. This applies after any transportation, including delivery and relocation.

Storage & wine quality

What is the ideal storage temperature for a mixed wine collection?

For a single-zone wine cooler storing a mixed collection of red, white and sparkling wines, 10–13°C is the optimal compromise. This temperature range preserves all wine types without compromising any of them, and is particularly suitable for long-term storage where wines will age over months or years before serving.

Can a wine cooler be used for both storage and serving?

Yes. Multi-zone wine coolers allow different temperature zones within the same unit — a warmer lower zone for red wines ready to serve, and a cooler upper zone for whites and sparkling wines close to serving temperature. Single-zone models are better suited to long-term storage where wines are moved to a separate serving environment before opening.

Why can't I just use a regular kitchen fridge to store wine?

A standard kitchen refrigerator runs at 2–5°C — far too cold for long-term wine storage. It also vibrates significantly from the compressor, has very low humidity which dries out corks, and frequently cycles between temperatures. All of these factors degrade wine quality over time. A dedicated wine cooler addresses all four critical storage factors: temperature stability, vibration, humidity and UV protection.

After-sales & service

Is after-sales service available across Europe?

Yes. Dunavox maintains a pan-European after-sales and service network covering all major markets. As a manufacturer-led brand, Dunavox ensures long-term parts availability and consistent service standards — important for both domestic customers and professional project teams managing multiple installations.

Why does after-sales support matter when choosing a wine cooler brand?

For built-in and fully integrated appliances, replacement is far more complex than for freestanding units — furniture may need to be partially dismantled to access the cooler. Choosing a manufacturer-led brand with stable product lines and European service coverage significantly reduces this risk and ensures that compatible replacement units remain available over the lifetime of the kitchen.
