The temperature of the wine cooler is of paramount importance for the ideal wine storage. Inappropriate temperature can expand or shrink certain substances in the wine, causing oxidation and damage to its organoleptic properties.

The ideal wine storage temperature is between 10° and 16°C, avoiding temperature variations as much as possible and trying to maintain the ideal temperature between 14° and 15°C. A temperature above 25°C, on the other hand, will irreparably compromise the characteristics of the wine.
 
Mono or dual temperature?
According to your wine storage needs, you can choose between a single- or dual-zone wine cooler.

Single Zone Wine Coolers
They are perfect for long-term storage and aging of the wine collection. You can set a single temperature for the whole wine cooler.

Dual Zone Wine Coolers
Perfect for immediate wine consumption, it keeps and preserves bottles, just ready to be uncorked.  In the dual zone wine coolers, the upper cabin temperature must always be lower than in the cab below. It is advised not to exceed the 5° temperature grades of difference between the two areas. Too large temperature difference between the two zones forces a continuous on and off switching of the heater and that consequently increases energy consumption. 

Where to place your wine cooler
The outside temperature also affects the degrees and performance of the wine cooler, so avoid placing the wine cooler in areas subject to high temperature changes, such as a terrace where the temperature may be too high due to constant sun exposure, or in a garage where the degrees may drop too low. Make sure that there is enough air flow.
 
Wine coolers with static refrigeration
The display indicates the inside temperature of the cooler that will never be equal to the display setting, since the internal temperature is altered by many factors such as:

outdoor temperature, how many times is opened and closed the door, the cooler’s position, corners, sun, floor heating, storage of bottles, etc.

The display shows the desired temperature, internal and external probes give a signal to the compressor as soon as the cooling has reached about 2° below the set degrees. For this reason there can be a difference between the set and the internal temperature about even 3°.



Between the top shelf and the lower shelf can also be 3° of difference.



Wine coolers DO NOT HEAT the temperature from the outside, but they lower the temperature, therefore if the environment in which it is positioned is lower than the set temperature in the wine cooler, the set temperature will not match.



In wine coolers with static refrigeration a temperature difference between the lower and upper area is normal.
The compressor pumps cold air from above into the wine cooler. Cold air is heavier than warm and it falls down. Therefore is the lower part of the wine fridge the coldest area where to store white wine bottles. The upper area is more temperate and intended to store red wines. The difference in degree is not quantifiable as it depends on the outside temperature, the inside temperature and the humidity.



In the wine cooler with static refrigeration exists an ideal climate between temperature and humidity, which is suitable to store wine. This wine cooler has no ventilation and it is therefore more subject to condensation. This might happens especially in the summer months, when temperature differences between the inside of the wine cooler and the outside environment prevail.
If the door is opened continuously, or there are large temperature differences between in and out, ice may build up in the wine cooler. Turning off the wine fridge for 24 hours can easily fix this.
