Can a wine cellar be installed in an unheated room?
With the onset of cold weather, a question frequently arises: can a wine cellar be installed in a garage, utility room or other unheated room? The answer depends on a number of factors, not least the appliance's climate class... and the presence of a winter system.
What is the climate class of a wine cellar?
Every wine cellar is designed to operate within a defined range of ambient temperatures. This is called the climate class, indicated on your appliance's technical data sheet.
For example:
- Class N: optimal operation between 16 and 32°C
- SN class: between 10 and 32°C
- ST class: between 16 and 38°C
If the room temperature falls below the specified range, the cellar may cease to function properly: it will no longer cool, or on the contrary, the temperature inside will drop dangerously for your bottles.
The role of the winter system
Some wine cellars, particularly ageing cellars, are equipped with a winter system. This electronic device enables the cellar to maintain a stable interior temperature, even if the room in which it is located becomes temporarily colder than expected.
How does it work?
- The winter system acts as a relay.
- It activates an internal heating element to prevent the cellar temperature from dropping too low (below 10 or 12°C, for example).
- It's automatic, but limited in its effectiveness.
The winter system does not turn your cellar into a heating system, nor does it compensate for a constantly icy environment. It acts only as a short-term back-up solution.
Things to remember

Bad practices |
Good practice |
|
Install a conventional cellar in an unheated garage without checking the climate class. |
Check that the cellar has a winter system if it is located in a cold room. |
|
Think that the winter system is sufficient for a room at 0°C. |
Use a cellar suitable for climate class SN (10°C min). |
|
Leave the cellar connected in a room below 5°C for weeks. |
Monitor room temperature regularly and avoid excesses. |
Recommendations La Sommelière
- If you want to install your wine cellar in a garage, basement or unheated room, opt for a model with a winter system AND a suitable climate class.
- The winter system is ideal for coping with a temporary drop in temperature, but is no substitute for a stable, protected environment.
- For long-lasting, safe use, opt for a room that remains between 10 and 32°C all year round.
Conclusion
Yes, it is possible to install a wine cellar in an unheated room... provided you choose the right appliance and understand the limits of the winter system. This device is a one-time support, not a permanent solution. To preserve your bottles in the best possible conditions, be sure to follow the manufacturer's instructions and, ideally, install your cellar in a temperate, stable environment.
