Wine Cellar Cooling System

As we all know,climate control 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. Thenow wine cellar constant temperature and humidity system can maintain the proper wine storage enviornment in the range of 10~16 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 65-75% RH. This way, the corks are kept tight for long periods.

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.

What is the difference between a regular air conditioner and wine cellar cooling system?
  • Regular air conditioners are meant to go down to 18 ℃, possibly 16 ℃ at the lowest. But wine is meant to be stored at around 12oC in order to age and evolve properly.
  • Standard AC units are built to cool the air quickly and to draw the humidity out of the air to make the room feels comfortable.The humidity helps to keep corks moist. While the wine cellar cooling units are designed to cool the air at a much slower rate to maintain the humidity in the room.
  • Normally wine cellar cooling units are always designed to run all year round without interruption. However,the failure rate of standard AC units is very high at such a frequency running.
  • Humidification is optional for Thenow's wine cooling units,this is obviously a normal AC unit cannot provide.
Wine Cellar Cooling Units Split System
Thenow wine cellar cooling units split system is intended for cellars without access to proper ventilation. They are known for their efficiency and longevity. Each unit is designed to maintain a consistent temperature and humidity in spaces where proper ventilation is not feasible. The units are functionally divided into two sections,the evaporator and the condenser. The evaporator is installed inside and the condensing unit can be placed as far as 30m away with external ductwork connections. Since it exhausts outside, split cooling systems operate quietly and reduce vibration inside the cellar, which is believed to negatively affect the quality of wine.

Wine Cellar Cooling Units Self-contained
Thenow wine cellar cooling units self-contained is best suited for home or light commercial proper wine storage. This unit is intended for use in cabinets or smaller wine storage rooms up to 15 cubic meters. Designed to lower the temperature at its best scope 10~16 degree centigrade, and maintains the humidity at optimal levels, between 50 and 75 percent. There are cabinet cooling units with optimized bottom return air and top return air,it is free to install the unit in the top and bottom of the cabinet.Multiple options of rear or top or bottom return grille with little duct work are convenient for various wine room installations.
