Construction and installation of reputable and quality cold storage for wine preservation

Wine cold storage is a dedicated refrigeration system that holds the temperature precisely between 10 and 18°C and keeps humidity at 60 to 75%. This is the ideal environment for fine wines to keep maturing and to prevent premature oxidation. Completely different from an ordinary food cold storage cold store, a wine room demands strict control of vibration, the elimination of UV light and careful management of air convection: technical standards that a domestic refrigerator or a standard industrial chill room simply cannot meet.

With Vietnam's imported wine market growing strongly, investing in a properly engineered industrial refrigeration system for restaurants, five-star hotels and large storage facilities is essential to protect the value of the stock. With more than 20 years in the industry, Tân Long provides comprehensive cold storage design wine storage solutions, from site survey and installation through to scheduled maintenance, for every size of facility from 50m² to several thousand m².

Why can wine not be kept in an ordinary cold store?

Wine is considered a living thing: even after bottling it keeps maturing through micro-oxidation across the cork. Any small deviation in the storage environment can upset the delicate balance between acid, tannin and sugar. The wine then loses its flavour structure and may even turn harsh and sour, destroying the value of top-tier bottles.

Lines food cold storage normally runs between -2°C and +5°C, far below the 10 to 18°C band that wine requires. When the temperature drops too low the cork contracts, air seeps into the bottle and uncontrolled oxidation accelerates. On top of that, refrigerators and standard industrial refrigeration compressor cold stores generate continuous vibration while running. That vibration breaks up the settled sediment, dulls the colour and seriously affects the wine's natural flavour.

UV light is another damaging factor that is often overlooked. UV breaks down the phenolic compounds in wine, changing its colour and creating unpleasant aromas. That is exactly why traditional cellars in France and Italy are built deep underground, completely cut off from sunlight. Investing in a professional cold storage wine system from Tan Long gives you absolute control over temperature, vibration and light, guaranteeing perfect storage conditions for your collection.

Standard temperature and humidity ranges for each type of wine in cold storage

There is no single temperature that suits every wine. Each type has its own chemical structure and therefore needs a specific temperature and humidity range to preserve its core value. The table below summarises the strict technical standards normally applied when designing a cold storage wine for Tân Long's B2B customers:

Type of wineStorage temperatureOptimum humidityExpert technical note
Red wine12 to 18°C (54 to 64°F)60 to 70%Lay bottles horizontally and keep them entirely out of UV light
White wine7 to 12°C (45 to 54°F)60 to 75%Needs a lower temperature than red wine
Sparkling wine (Champagne)5 to 8°C (41 to 46°F)60 to 75%Very sensitive to mechanical vibration
Spirits (whisky, cognac)10 to 15°C (50 to 59°F)50 to 65%Screw-cap bottles, so humidity has less effect
Sake, shochu5 to 10°C (41 to 50°F)55 to 70%Must be kept strictly chilled once opened
Fortified dessert wine12 to 15°C (54 to 59°F)60 to 70%Can be stored upright once the protective cap is fitted
Craft beer (in storage)2 to 8°C (36 to 46°F)50 to 60%Keep the storage area separate from the wine

Red wine: hold between 12 and 18°C with stable temperature control

Red wine is high in tannin, so it needs a steady 12°C to 18°C for the tannin structure to keep developing without degrading. What matters is not only the exact figure but the absolute stability of the environment. A swing of more than 2°C in a day can age the wine faster than normal and strip out its complex aromatic notes. To solve this, Tân Long integrates a PLC control cabinet with multi-point temperature sensors, keeping the temperature deviation inside the store within ±0.5°C.

White and sparkling wine: 5 to 12°C, plus anti-vibration measures

White wine and champagne need significantly lower temperatures, between 5 and 12°C, to preserve their crisp acidity and natural bubbles. This is a serious technical challenge because industrial refrigeration compressor units generate continuous vibration while running. In its design, Tân Long installs the compressor unit completely separately from the storage room. The two are connected through anti-vibration piping with dedicated rubber pads, cutting vibration to below 0.5 mm/s in line with international wine-preservation practice.

Spirits (whisky, brandy, sake): 10 to 15°C

Spirits are less sensitive to temperature swings than wine, but they still need a stable environment between 10 and 15°C. Because spirit bottles are normally stored upright, the cork does not touch the liquid and humidity matters far less. Even so, a industrial refrigeration system designed for spirits must provide continuous ventilation. That prevents high-concentration alcohol vapour from building up, removes the fire and explosion risk, and satisfies the applicable technical safety regulations.

Six core technical factors in wine cold store design

To build a cold storage wine system that meets international standards, Tân Long's engineers focus on the six technical details below to guarantee operating performance and product safety:

Wine preservation in cold storage

1. PU insulation panel: 100mm minimum thickness

The envelope of a wine storage system normally uses PU (polyurethane foam) panel with a density of 40 to 42 kg/m³ and a thickness of 100mm to 150mm. In the south in particular, where Ho Chi Minh City ambient temperatures regularly swing between 28 and 38°C, a 100mm panel keeps the room temperature stable and saves considerably more energy than ordinary EPS panel. Tan Long uses airtight camlock joints that eliminate thermal bridging at the seams completely, holding the cold for the wine even through a power cut of four to six hours.

2. Refrigeration system: choosing the right refrigerant

R404a and R449a are currently the two most common choices for dedicated refrigeration systems in the 5 to 18°C band. R449a is the newer-generation refrigerant, with a GWP 68% lower than R404a, and is the preferred direction under Europe's F-Gas rules for exporting businesses. Depending on the scale and operating objectives of each refrigeration compressor, Tân Long will advise on the refrigerant that best balances performance and environmental protection.

3. PLC control panel and IoT monitoring sensors

A system cold storage wine for the B2B segment needs continuous 24/7 monitoring. Tân Long integrates a PLC control cabinet solution that logs temperature automatically and sends an SMS or email alert the moment a deviation occurs. The data is retained for 365 days, so the business can easily export reports for quality audits against demanding standards such as FSSC 22000 or ISO 22000.

4. Dedicated insulated cold store doors

A wine store door has to be absolutely airtight to prevent heat loss during loading and unloading. We supply T-Light cold storage door and hinged doors fitted with four-layer magnetic gaskets, UV-blocking toughened glass and smart safety locks. For stores larger than 100m², an airlock vestibule is normally recommended to minimise the heat load on the system.

5. Controlling light and harmful UV rays

Warm-white LED lighting in the 2700 to 3000K range, emitting no UV, is mandatory in a wine store. Viewing panels should use Low-E glass or glass with a special UV-filtering film. This lets the owner see the collection inside without affecting the chemical structure of the wine.

6. Racking design and airflow optimisation

Racking in 304 stainless steel or oak, with at least 30cm between rows, lets the cold air circulate evenly. In the cold storage designprocess, the position of the evaporator has to be calculated carefully so the airflow does not blow directly onto the bottles and cause localised thermal shock. Well-planned airflow is the deciding factor in achieving a uniform temperature at every point in the store.

The Tân Long standard wine cold store installation process

Tân Long applies a professional five-stage delivery process, from the on-site survey through to detailed handover, so that the cold storage wine runs reliably and meets its demanding technical specification from the very first day of operation:

StageScope of workEstimated duration
1. Survey and consultationMeasure the actual site, identify the specific wines to be stored so the cooling load can be calculated, and advise on the most suitable refrigerant.1 to 3 days
2. Technical designProduce 2D and 3D CAD drawings, select the PU panel thickness, design the PLC control cabinet, the compressor unit and a racking layout that optimises airflow.3 to 7 days
3. Materials supplyThe PU panel is produced directly at Tân Long's plant in Tây Ninh (formerly Long An), together with genuine imported cold storage equipment from the world's leading brands.7 to 14 days
4. InstallationSkilled technicians from Tan Long install on site, checking 100% of the joints and the door for absolute airtightness.5 to 15 days
5. Handover and warrantyA continuous 24-hour test run, full handover of the technical documentation, operator training, and activation of the 12-month warranty together with the scheduled maintenance package.1 to 2 days

This closed-loop process lets us control quality tightly at every stage and deliver the best possible cold storage design wine storage solution for restaurants, hotels and large distribution warehouses in Vietnam.

Investment efficiency and returns from a wine cold storage system

Investing in the system cold storage wine is not simply an operating cost; it is a strategic asset for the business. The budget varies with three main technical variables: the actual floor area, the specific operating temperature band, and how much automation is built into the control system.

Frequently asked questions about wine cold storage

1. What temperature should a wine cold store run at?

Wine is stored between 7 and 18°C (45–64°F) depending on the type: red wine needs 12–18°C, white wine 7–12°C and sparkling wine 5–8°C. More important than the number is stability: a swing of more than 2°C a day ages wine prematurely.

2. How does a wine cold store differ from a food cold store?

A wine cold store runs at 5–18°C, far warmer than a freezer store at -18°C to -40°C, while also holding humidity at 60–75%, eliminating UV light and keeping vibration to a minimum. A food cold store has none of these features and damages wine over the long term.

3. What is the minimum wine store size for a restaurant?

A high-end restaurant with 200–500 bottles typically needs a 10–20m² room (roughly 108–215 sq ft). A restaurant wine room also has to look good: oak or stainless steel racking, Low-E glass doors and warm 2700K LED lighting, so it works as a display as well as a store.

4. How much does a 50m² wine cold store cost to install?

A 50m² wine cold store (about 538 sq ft) in Vietnam in 2026 costs between VND 200 and 350 million to install, depending on the level of automation and the equipment chosen. Contact Tân Long for an accurate quotation based on your project's actual specification.

5. Does Tân Long build wine cold stores outside Ho Chi Minh City?

Tân Long builds wine cold stores nationwide, including Hà Nội, Đà Nẵng, Cần Thơ and the industrial parks in Tây Ninh, Bình Dương and Đồng Nai. Our technical team mobilises on site within 48–72 hours of contract signature.

6. Do wine cold stores need scheduled maintenance?

Yes. A wine cold store needs servicing twice a year: cleaning the evaporator, checking refrigerant pressure, lubricating the door gasket and updating the PLC software. Tân Long offers annual maintenance contracts costing 5–15% of the initial investment.

Frequently asked questions about wine cold storage

Why does wine need a dedicated cold store?

Because high and fluctuating temperatures age wine quickly, affecting both flavour and structure. A dedicated store holds the temperature steady so the wine develops properly over time.

How does a wine store differ from a food store?

Temperature stability matters more than low temperature; humidity has to be controlled so the cork does not dry out; and vibration and light must be limited. None of these are concerns for an ordinary food store.

Why does humidity matter in a wine cellar?

Because a dry cork shrinks, opening a gap for air to reach the wine, which then oxidises and spoils. The right humidity keeps the cork swollen enough to seal the neck of the bottle.

How does vibration affect wine?

Constant vibration disturbs the sediment and is believed to interfere with the wine's natural ageing. That is why the condensing unit should sit away from the storage area, so vibration is not transmitted into the racks.

Does light affect wine?

Yes. Light, and ultraviolet in particular, degrades wine and strips out its aroma. A wine store should use low-intensity lighting switched on only when someone is working inside.

Does Tân Long build wine cold stores?

Yes. Tân Long designs and builds wine storage rooms to the required standards of temperature stability, humidity control and vibration-damped layout for the storage area.
