Wine Cellar Humidity

Along with temperature, wine cellar humidity is one of the most important aspects of preserving wine. For this reason, it is absolutely essential to ensure your wine cellar humidity level stays constant and is exactly where you need it to be. Because wine “breathes” through the cork, and this is how it ages, fluctuations in wine cellar humidity can speed up the aging process and can even result in corked wine.

The recommended level of wine cellar humidity for premium and stable aging of wine is anywhere from 55-75%, depending on a number of factors. Not only does humidity above 75% accelerate the aging process, but mold often forms above 80%, causing destruction to the label and integrity of the bottle, as well as any wooden racking. Further, wine cellar humidity that is too low can dry out the cork, letting excess air in and causing the cork to split when opening the bottle.
