How to Convert a Wine Cooler Into a Humidor

A wine cooler is not just for storing your favorite vintages; it can also be transformed into a functional humidor for keeping cigars in optimal condition. This unique modification repurposes a wine cooler into a device that maintains the perfect temperature and humidity for storing cigars, very similar to the controlled environment that a wine cooler provides for wine. Converting a wine cooler into a humidor offers several benefits such as cost-effectiveness, ample space for storage, and the ideal conditions for preserving the flavor, aroma, and quality of your cigars.

In the following sections, we’ll guide you through the process of this conversion, helping you create the perfect haven for your cigars.

How to Convert a Wine Cooler Into a Humidor

Gather the Necessary Supplies

To convert a wine cooler into a humidor, you will need the following items:

  • A wine cooler (of any size)
  • Humidifier and hygrometer (to regulate humidity levels)
  • Spanish cedar planks or shelves (for cigar storage)
  • Distilled water (for humidification)

Cleaning and Preparing the Wine Cooler

Thorough Cleaning Process

Before you begin the transformation, it’s crucial to conduct a deep clean of the wine cooler. Start by unplugging and emptying the wine cooler. Use a mild detergent mixed with warm water to clean the interior surfaces. Use a soft cloth or sponge to avoid scratching or damaging the interior. Take care to cleanse every corner, crevice, and shelf, ensuring no residue or dirt remains.

Removing Any Residual Odors

Next, it’s time to address any lingering smells within the cooler. Wine, like cigars, has a strong aroma that can infuse into the cooler’s interior over time. To remove residual odors, prepare a solution of equal parts water and white vinegar. Wipe down the interior again with this solution and then leave the door open for a day or two to allow it to air out.

Ensuring Proper Insulation

Lastly, ensure that your wine cooler is well-insulated to maintain the stable temperature and humidity levels that cigars require. Check the door seals for any signs of wear or damage that could allow air to escape. If you find any issues, consider replacing the door seal or adding additional insulation.

Now that your wine cooler is clean, odor-free, and well-insulated, you’re ready to proceed to the next steps of the conversion.

Installing Humidity Control System

Humidity Control System

The device should be positioned in a way that allows for an even distribution of humidity. A typical practice is to place it on the lowest shelf or at the bottom of the cooler. This takes advantage of the fact that moisture naturally rises, ensuring all cigars are exposed to consistent humidity levels.

After installation, regularly monitor and adjust humidity levels. The optimal humidity for cigar storage is typically between 68% and 72%. Use a reliable hygrometer to monitor these levels. To increase low humidity, add distilled water to the humidifier. If the humidity is too high, briefly open the cooler door to release moisture. Regular monitoring and adjustment will keep your cigars in ideal condition.

NOTE: Choosing the right humidification system is essential for maintaining the ideal cigar environment. With options ranging from humidity pouches to electronic humidifiers, finding the perfect device for your needs is easier than ever.

Adding Spanish Cedar Lining and Shelves

Spanish cedar is the top choice for cigar humidors due to its benefits. It naturally repels insects, resists mold, and has a pleasant aroma that enhances cigar flavor. Additionally, it absorbs excess moisture, maintaining consistent humidity levels.

To fit the interior of your wine cooler, measure and cut the cedar planks or shelves. Spanish cedar is easy to work with using basic tools. Line the sides, back, and bottom of the cooler with the cedar planks. If using shelves, securely stack them inside the cooler.

Organizing and Storing Cigars

Arrange the cigars horizontally on Spanish cedar shelves, leaving space for air circulation. Avoid tightly packing or allowing them to roll around. Consider using trays or cigar boxes for a more organized system. They make categorization and management easier while preserving flavors and aromas. Place them on the shelves of the converted cooler, ensuring effective air circulation.

Locate your humidor in a place with a stable temperature and away from sunlight or heat sources. Also, try to limit the frequency and duration of the door opening to maintain stable internal humidity levels.
