How to Lower the Humidity in My Wine Cooler

Jump to Section

If you're a wine enthusiast, you should know how important it's to preserve your wine cellar. Your wine collection is a significant investment, so you want to make sure that it's properly taken care of. One of the things that you need to control is the humidity level inside your wine cellar.

If the humidity is too high, it can cause the cork to dry out and allow oxygen to enter the bottle, which will ruin the wine. This can also allow mold and mildew to form, which can damage the labels and ruin the flavor of the wine.

Here are some of the ways how to cut down on humidity inside a wine cooler:

Install a Cooling System

The first and most obvious way to lower the humidity in your wine cellar is to install a cooling system. This will help to regulate the temperature and keep the air dry. There are a few different types of cooling systems that you can choose from. Make sure to do some research on the best coolers and fridges with better cooling units before you make a purchase. The system will work independently to keep levels steady and consistent by cycling warm air through its compressor, reducing heat and humidity.

There are also a number of factors you need to consider when choosing the best type of cooling unit for your cellar. You need to consider the size of the cellar and the unique variables that can affect its temperature. You should also consider the amount of space and airflow required for a cooling system, the noise it can generate, and its budget.

Create a Vapor Barrier

You can also create a vapor barrier in your cellar by installing an insulation system. This will help keep the air dry and cool and reduce the amount of energy required to maintain the temperature in your cellar. Wine storage may require a different temperature than the rest of the house or outside environment.

This can create temperature imbalance, leading to condensation, increased humidity, and mold growth. The vapor, therefore, acts as a barrier between the cellar and the outside environment, preventing external air from upsetting the controlled atmosphere within the cellar and regulating the humidity levels.

To be effective, a vapor barrier should encapsulate the entire cellar and lie between the foundation wall and the insulation. The most common vapor barrier material is high-density closed-cell foam. This is used in place of plastic sheeting and acts as a vapor barrier and insulation.

Install a Temperature and Humidity Gauge

Install a temperature and humidity gauge in your wine cellar. This will help you keep track of the conditions in your wine cellar and make necessary adjustments to ensure that your wines are stored at the optimum temperature and humidity. By knowing the daily levels and fluctuations that occur, you'll have the opportunity to make temporary, seasonal, or permanent changes to humidity levels when needed.

A hygrometer will help you measure the amount of water vapor in the air surrounding your wine collection. There are also smart hygrometers that you can pair with your smartphone, instantly sending you a notification if levels change, enabling you to act in a timely manner.

Run a Dehumidifier

If you don't already have a dehumidifier in your wine cellar, now's the time to invest in one. By removing excess water vapor from the air, a dehumidifier can help maintain ideal humidity levels for wine storage, preventing everything from corks drying out and shrinking to mold growth. Wine cooling units for wine cellars in humid climates should be sized to operate long enough to dehumidify the air.

Don't Open Your Wine Cellars More Than Necessary

Every time you open your wine cellar door, humid air from outside rushes in, potentially raising humidity levels and putting your collection at risk. Limit the number of times you open your wine cellar to only when absolutely necessary and close the door as quickly as possible. 

Understand Your Wine Fridge Controls

Most wine fridges come with a humidistat, a thermostat for humidity. By understanding how your humidistat works, you can make sure that your fridge is set to the ideal humidity level for wine storage, usually between 50% and 70%. Learn how cold a wine cooler gets to know the right temperature to use so you don’t exceed the limit.

Store Your Wine Cooler in a Dry, Cool Environment

One of the best ways to help keep humidity levels in your wine fridge low is to store the fridge itself in a dry, cool environment. If your wine cooler is located in a kitchen or other warm area of your home, consider moving it to a cooler, drier spot.

Remove Mold and Mildew from Your Wine Cooler

Before taking this step, make sure you know how to remove mold and mildew from your wine fridge. If you find mold growing inside your wine cooler, it's important to clean it as soon as possible. Not only is mold unsightly, but it can also affect the flavor of your wine. To clean mold from a wine cooler, start by unplugging the fridge and removing all of the bottles of wine. Next, clean the fridge's interior with a solution of equal parts water and bleach.

Pour a little bleach on a soft sponge or cleaning rag, then apply it directly to the molded areas. Apply bleach sparingly, as too much can damage the interior of your fridge. Once you've cleaned the mold, rinse the area with clean water and dry it thoroughly with a soft cloth.

Check the Drainpipe

Make sure you check your wine cooler's drain pipe before summertime. A clogged pipe will leak and cause condensation. Take out your drainpipe from the wine refrigerator, then take a snake and push the clog through the drainpipe. If it doesn't budge, sprinkle a teaspoon of baking soda into the drainpipe and pour two cups of water down the drainpipe.

FAQs on How to Lower Humidity in a Wine Cooler
