The Importance of Wine Cellar Humidity


You probably already know how important storing your precious wine collection in a cool, dark place is. But here's something you might not have considered: Humidity.

Maintaining the ideal wine storage humidity is crucial if you plan on aging your wine. However, it's easier said than done. Controlling humidity can be quite tricky, and unless you're equipped with specialized gear or a top-notch wine cooling system, it's almost impossible to get it right.

In this post, we'll take a closer look at why wine cellar humidity is important and how a wine cellar humidifier can help you achieve the ideal cellar environment for your wine collection.

What is Humidity?

What is Humidity | Wine Coolers Empire - Trusted Dealer

Humidity refers to the level of moisture or water vapor present in the air, which is usually expressed as a percentage of the maximum amount of water vapor that the air can hold at a given temperature and pressure. It is influenced by various factors such as temperature, precipitation, and wind, which can cause significant variations in humidity across different environments and weather conditions.

For instance, warmer temperatures tend to hold more moisture and generate higher humidity levels, whereas cooler temperatures hold less moisture and create lower humidity levels. Humidity plays a vital role in various aspects of our lives, including weather patterns, indoor air quality, comfort, and even wine storage.

The Importance of Humidity in Wine Cellars

Wine cellar humidity refers to the level of moisture in the air within a wine cellar. It plays a critical role in the storage and aging of wine, as too little or too much humidity can have negative effects on the quality and flavor of wine.

The ideal relative humidity for storing wine is 50 to 70 percent. Without the ideal wine cellar humidity level, it can negatively impact the quality of the wine in many ways.

Low Humidity Levels

Low humidity in wine cellars (below 50%) can cause corks to dry out and shrink, allowing air to seep into the wine bottle. This can oxidize the wine which can lead to off-flavors and aromas. In addition, low humidity levels can cause the wine to evaporate through the cork, which can result in a loss of volume and flavor concentration.

High Humidity Levels

High humidity in wine cellars (higher than 70%) can create a breeding ground for mold and mildew to grow. Mold can damage the labels on wine bottles and cause cork deterioration, which can ultimately result in an unpleasant odor or flavor in the wine and potentially make it unsuitable for consumption.

Other Factors That Affect Wine Storage

There are several factors besides humidity that can affect wine storage, including:

  • Temperature: The ideal wine cellar temperature and humidity are important to ensure that wine does not spoil or age too quickly. The best temperature for wine cellar is between 55-57°F (13-14°C), as temperatures that are too high can cause the wine to oxidize and develop off-flavors and aromas, while temperatures that are too low can slow down the aging process and prevent the wine from reaching its full potential.

  • Light: Exposure to light, especially ultraviolet light, can lead to premature aging. Wine should be stored in a dark or dimly lit area to prevent light damage.

  • Vibrations: Excessive vibrations can disrupt the sediment in the wine bottle, affecting the flavor and aroma of the wine. Wine should be stored in a location where it will not be subjected to excessive vibrations.

  • Air quality: The quality of the air in the wine cellar can affect the wine. Strong odors from cleaning agents or other chemicals can permeate the cork and affect the flavor of the wine. We recommend integrating a UV-C light bulb into your wine cooling unit to serve as an air purifier. The UV-C Light Technology effectively kills bacteria and prevents mold formation within the system.

Monitor and Control Humidity in Wine Cellars

Monitoring and controlling wine cellar humidity is essential to preserving the quality of wine. Here are some tips for maintaining proper humidity levels in a wine cellar:

  1. Seal the wine cellar. Make sure that the wine cellar is well insulated and properly sealed to prevent moisture from entering or leaving the space. Inspect the cellar regularly for any leaks or drafts.
  2. Maintain consistent temperature. As mentioned earlier, temperature can also affect wine storage. Keep a consistent temperature by installing a wine cellar cooling system.
  3. Use a hygrometer to measure the humidity level in the air. Place a hygrometer in the wine cellar to monitor the humidity levels regularly. Ideally, the humidity level should be between 50-70%.
  4. If the humidity level is too high, consider installing a wine cellar dehumidifier to reduce the humidity level. Wine room dehumidifiers can help prevent mold growth and label damage.
  5. If the humidity level is too low, consider installing a wine cellar humidifier to increase the humidity level. Humidifiers are specifically designed for adding humidity to a wine room.
