In this article, we’re going to be discussing how exactly you can reduce the humidity in a wine refrigerator. This is so that you can keep your wine collection in a cool environment, which is conducive to maintaining its condition.

Now, it might seem a little odd to think that minimizing humidity is such a big deal. As a general rule, the cooler your refrigerator is, the less volatile the air will be, and the less moisture will appear inside the wine fridge itself.

You can tell if a wine fridge is too humid, because the back wall of the unit will attract moisture, and water droplets will form and drip onto the bottom panel of the unit.

So how can you reduce the humidity within your wine cooler?

Although this video describes how to eliminate mold in a conventional refrigerator, the same solutions apply to a wine fridge:

However, here are some basic proven methods that you can implement:

1) Store your wine cooler in a dry, cool environment

This is one of the simplest, yet most effective ways to reduce internal humidity within your wine cooler. It works because it means that if external air is somehow getting into the unit, that air is not hot, and therefore cannot increase humidity.

One of the best locations to keep your wine cooler is in a cellar, as they are known for their cooler temperature. Additionally, your kitchen is still a great environment, for as long as the wine fridge is not in direct view of sunlight.

2) Understand your wine fridge controls

Another more obvious tip on the list, it’s understanding the controls on your wine fridge, because a lot of them actually have humidity controls. If this means referring to the unit’s instruction manual one evening, we highly recommend making that time investment to learn everything there is to know about controlling your wine cooler.

3) Don’t open your fridge more than necessary

Opening your wine fridge (and leaving it open) regularly will cause warm air to enter the unit, causing condensation and moisture to form, which increases the humidity.

Therefore, it’s important to make sure that you’re not opening the unit too often. Additionally, the environment that the unit is stored in will also have an impact on this, which is why we recommend positioning the wine fridge in a dry, cool environment, such as a wine cellar.

For most people, they’re opening their wine cooler to either replenish or remove wine, so with some preparation, this can usually be done at the same time.

4) Use a desiccant dehumidifier

Another effective way to minimize internal humidity is to simply use a desiccant dehumidifier, which can easily be placed on the inside of the wine cooler. As the name suggests, the main purpose of this product is to reduce humidity, so it’s perfect for the task.

Frequently Asked Questions

In this section, we’ve addressed some of the most common questions that we receive about reducing humidity in a wine fridge.


What happens if you see mold forming in your wine fridge?

If you’re beginning to see mold forming in your wine fridge, it simply means that there is too much humidity and moisture in the wine cooler, and therefore you’ll want to follow these instructions to resolve the situation:

  1. Remove all of your wine collection from the wine fridge and store the bottles in a cool, dark environment for the time being.
  2. Turn your wine refrigerator off and unplug it from the mains supply, especially whilst cleaning.
  3. Spray some bleach (if in sprayable form) on the area where mold is forming, or use a cloth/sponge with some bleach, and begin to wipe the area, making sure that the bleach is in surplus, covering the mold itself.
  4. Leave for a few minutes and then test to see if the mold is loosening
  5. Once the mold is loose enough, remove it with a cloth
  6. Use a fresh damp cloth, to wipe the area to remove any excess bleach
  7. Dry the area using a paper towel (avoid a towel unless you’re sure all of the bleach has been removed).
