Environmental humidity of the wine cellar: the relative humidity requirement in the wine cellar is 55%-70%, the lower limit of relative humidity is not less than 50%, and the upper limit of relative humidity is not higher than 75%. We all know that the cap of red wine is cork stopper. And the red wine is generally placed obliquely in the wine cabinet. One end of the cork will be in contact with the wine for a long time, so that the placement can provide a certain sealing effect.
If the humidity in the wine cellar is too low, the air contact end of the cork will gradually dry out, causing the cork to shrink into the bottle. When contracted to the mouth of the bottle and exposed to red wine, the outside air accelerates the oxidation of the wine. Long-term storage can cause wine to deteriorate. Of course, the humidity is not as high as possible, because too high humidity will cause mildew in the cork and breed bacteria. At the same time, too high humidity will cause damage to the interior decoration. It is recommended that the optimal setting relative humidity be 55%-65%.
For small areas, air conditioning can be used for air temperature control, and humidity control requires the use of a wine cellar humidity control
