Wine Cellar Cooling System

Wine Cellar Cooling System

As we all know, wine cellar climate control system is an extremely important part of any wine cellar design, especially keeping constant and stable temperature and humidity environment. The role of the proper cellar cooling system plays is becoming obviously. The new wine cellar constant temperature and humidity system can maintain the proper wine storage enviornment in the range of 10~18 degree centigrade and 50~70% RH, whatever  your wine your wine cellar located in cool climate or temperature climate or hot and humid climates or hot and arid climates.

Wine storage options 

There are three main ways to store your bottles of wine safely and securely:

Wine cellar – this is the ideal way to store your wine bottles, temperature and humidity controlled ideally. Wine cellars are a cost effective solution for storing wine and are bespoke from one home to another.

A makeshift closet wine cellar – this is ideal for wine lovers and enthusiasts. It is a simple and quick way to store your wine bottles in any size space (small or large) in your house.
A makeshift closet wine cellar is perfect for an everyday drinker but not as effective as long term storage.

A wine cabinet or refrigerator – these are reliable ways to maintain the temperature of your wine bottles and are a worthwhile investment for wine professionals and wine merchants.  

Factors pronounced effect on wine storage

Storage of wine is an important consideration for long-term aging. While most wine is consumed within 24 hours of purchase, fine wines are often set aside for long-term storage. Wine is one of the few commodities that can improve in flavour and value with age, but it can also rapidly deteriorate if kept in inadequate conditions.

Proper storage comes with several factors namely temperature, humidity, storage stability, the presence of light, bottle positioning, and keeping wine away from strong odors etc. Constant temperature and proper humidity have the most pronounced effect on long time wine storage.

Wine Storage Temperature&Humidity Guide

Red wines are robust and slightly more resistant to heat than whites, thus the ideal storage temperature for such ranges from 10 – 15ºC (50 – 59ºF). Whites accept the given range, but some purists store them at slightly cooler temperatures ranging from 7 – 10 ºC (45 – 50 ºF) just to be safe.
According to some experts, storing wine at around 15 – 20 ºC is perfectly safe, provided that the temperature does not fluctuate. Fluctuations in temperature will cause the liquid to expand and contract, disrupting the molecules and adversely affecting the chemical reactions within the wine. Air molecules may give the tipple a “raisin-like” or stewed flavor.


Humidity should be kept at around 70% RH. This way, the corks are kept tight for long periods. When the humidity is higher than 70%, it will likely cause mold and degradation of the labels and glue. When the humidity is below 50%, corks will begin to dry out resulting in loss of liquid in the bottles and possible degradation of the wine.

Ideal temperature&humidity for some wines:

 Wine Ideal Temperature Ideal Humidity
Sweet & Semi-sweet Red Wine 14-16℃ 65%-70%
Dry Red Wine 16-22℃
Semi-dry Red Wine 16-18℃
Dry White Wine 8-10℃
Semi-dry White Wine 8-12℃
Sweet & Semi-sweet White Wine 10-12℃
Brandy <15℃
Champagne(Sparkling Wine) 5-9℃
Wine storage proper temperature is around12℃,but temperature range from 7-18℃ just to be safe.

Wine Cellar Cooling System FAQs

Why Do You Have To Choose The Professional Conditioner For Cellar?

Wine is very sensitive to temperature and humidity, and subtle changes will affect its state and quality, so the environmental design and the requirements for temperature and humidity conditions are extremely strict. Storage conditions of wine are generally 8℃-18℃at temperature, and humidity 60%-70%RH. The most suitable storage temperature for red wine is between 12℃and 16℃, while that for white wine and champagne is between 10℃and 12℃. High temperature will affect the acidity of the wine, while low temperature will lock the aroma and affect the growth of the wine. A qualified wine cellar should have a stable temperature of 8℃-18℃all year round. In order to achieve a good storage environment and avoid mildew deterioration of wine, try to choose walls, ceilings and floors with heat preservation and moisture functions. In addition, in order to maintain constant temperature and humidity, wine cellar air conditioning is an essential equipment.

Thenow wine cellar air conditioning units are specially designed for the wine cellar, more suitable for low temperature environment refrigeration, better control the temperature and humidity of the wine cellar, to achieve the stringent conditions for wine storage.

Why I Need to Install a Wine Cellar Climate Control in My Wine Cellar?

Yes,If you want to store wine for a long time ,,a wine cellar climate control is recommended.without an active method of controlling the temperature and humidity levels in the wine cellar ,you are unlikely to achieve a constant temperature and humidity.

Which Cooling Unit is Right for My Wine Cellar?

We have different models suitable for different sizes of wine cellars, you can choose the model suitable for you according to the capacity of your wine cellars, but there are other factors to consider, such as ambient temperature, whether the wine cellars are well sealed, etc. If necessary, you can contact us, Our engineers will select the model suitable for you according to the information you give.

Can I Install other Wine Storage Refrigerators in My Wine Cellar?

Yes, however, the refrigerator will exhaust heat into your wine cellar, which will work against the cooling unit.

Do I need to install the cooling unit and ventilator for cellars in basement?

It is often said that the basement is the best constant storage area for wine. Yes, of all the locations in the home, the basement is the most stable and the lowest temperature place, but it is not enough to meet the temperature and humidity requirements of a professional wine cellar. The year-round average temperature in basement is around 22 degrees, but what our wine cellar needs is 13-16 degrees. Humidity usually changes with the seasons, so you still need to install professional wine cellar air conditioners to keep the temperature and humidity in the basement. Then ventilation is required or not? We suggest that if your wine cellar is small, less than 50 square meters, it is completely unnecessary to install ventilation, only when your wine cellar is relatively large, you need to ventilate.

What kind of air conditioning units should I install for my cellar? Does a normal standard A/C is ok?

Nowadays, the wine cellar has become a standard feature in the decoration design of the villa and high performance building. The modern wine cellar design is professional with constant temperature and humidity, so what kind of equipment should people install for their cellar? And is it okay to install ordinary air-conditioning?

The wine cellar is dedicated to professional constant temperature and humidity, the temperature is 8-18 degrees, the humidity is plus or minus 5% of 65%, and it needs to be in a constant state. Let's look at ordinary air conditioners, the temperature control range of ordinary air conditioners is 16-30 degrees, this is just a set temperature, which is actually completely unreachable. Looking at the humidity, ordinary air conditioners will always dehumidify. As long as it is working in refrigeration, it will continue to dehumidify, the humidity level often at 30-40%. The state of the wine cork is very fatal, and it will quickly shrink the cork, and cause the wine to oxidize, which will deteriorate and become sour. From these two perspectives, it is impossible to install ordinary air conditioners in the wine cellar. It will directly harm the wine, but you should use a professional wine cellar cooling unit.

When Does The Build-in Humidifier Start Working?

The humidity sensor, located near the return air from cellar, will automatically turn on the humidifier whenever the cellar humidity is below the set point and turn it off when the cellar humidity reaches the set point. When the air passes through the wet-film pad, it absorbs moisture through evaporation of the water, this raises the humidity of the air taking into the cellar.
