Why should you care about finding the best wine cellar cooling unit? While it doesn’t make that big a difference when it comes to mass-market wines, proper wine cellar storage is the key to building an impressive collection of fine wines. Ideally, fine wines should be stored in a dark cellar at a temperature of about 55 degrees Fahrenheit (approximately 12.8°C) and 70 percent humidity. Otherwise, they may become “cooked” and develop an unpleasant flavor over time.
If you’re planning to build your own wine cellar, optimal temperatures and humidity are among the most important things you need to consider. The best way to ensure that your wines are aging the way they should is to buy a dedicated cooling unit. To help you make an informed decision, we have compiled a list of the five best wine cellar cooling units available right now.
Finding the Right Cooling Unit for Your Wine Cellar
Depending on the size of your cellar, a wine cooling unit can be a big investment. It is thus important to opt for a unit that best suits your storage needs and provides optimal ventilation.
There are three main types of wine cellar storage units:
- A through-wall wine cellar cooling system is a self-contained unit that is best suited for wine rooms and wine cabinets. Small and compact, it is easy to set up and doesn’t require any piping or ducting, which could also help reduce the overall cost of the installation.
- A ducted wine cellar cooling system uses ventilation ducts to keep your wine collection safe. Because the ducts can be set up on the outside, ducted coolers don’t require the installation of any large pieces of equipment inside the cellar.
- A split wine cellar cooling system is intended for cellars without access to proper ventilation. With a split cooler, the evaporator will be inside the cellar, while all the other pieces will be set up on the outside, allowing them to draw fresh air into the room.
Discovering the 5 Best Wine Cellar Cooling Units

The Final Word
Before you buy a cooling system for your cellar, you will need to consider your space and ventilation requirements and choose accordingly.

They are all competitively priced and come with comprehensive warranties that cover both parts and labor. Keep in mind that some manufacturers will ask you to provide the installation documents to activate your warranty.
