The idea of aging your wine in the refrigerator may seem practical to many, but in reality, it’s harmful to wine quality.
This article, brought to you by the Oeni app, available on iOS and Android, takes a deep dive into why this practice is discouraged and offers alternatives for optimal aging.
Unsuitable Temperature
Home refrigerators are generally set between 1 and 4 degrees Celsius, far too cold for most wines. According to Leonara Varvoutis, general manager and sommelier, that temperature shocks the wine. As a result, the wine’s tartaric acid crystallizes into “wine diamonds,” throwing off the balance and complexity of its flavors. This disruption leaves the wine unbalanced and negatively affects how it evolves over time.
Wine ages best at a steady temperature, slightly below room temperature, around 12 to 15 degrees Celsius. Too low a temperature slows the maturation process, preventing the wine from developing its complex aromas and flavors.
Humidity and Condensation
Another consequence of storing wine in the refrigerator is excess humidity, which can suffocate the cork. This lack of oxygen exchange prevents the wine from aging properly, or even aging at all. A damp, stifled cork can no longer regulate the airflow needed for harmonious maturation. Excess humidity can also encourage mold growth, compromising the integrity of the cork and, in turn, the wine.
Compressor Vibrations
Refrigerators, with their constant vibrations, are also harmful. Carolyn Lassen, sommelier at Husk Nashville, explains that these vibrations disturb the sediment in wines meant for aging, changing their flavor in an unpleasant way. Wines age better when they’re still, allowing sediment to settle naturally. Vibrations can also trigger unwanted chemical reactions, altering the wine’s structure.
Exposure to Light
Light, especially UV rays, can degrade wine over time. Home refrigerators aren’t designed to protect against these rays, increasing the risk of spoilage. UV exposure can lead to premature oxidation, reducing the wine’s quality and longevity.
Atmospheric Pressure
One often overlooked factor is the atmospheric pressure inside the refrigerator, which can also affect the cork and the wine. Fluctuations in pressure can cause the cork to contract and expand slightly, allowing air to seep in unevenly.
Temperature Fluctuations
Frequent opening of the refrigerator creates temperature swings that aren’t ideal for wine. Every time the door opens, the temperature shifts, exposing the wine to a cycle of cooling and warming. This back-and-forth can cause thermal stress, speeding up aging unevenly and often in damaging ways.
Alternatives for Aging Wine
- Store bottles on their side : Keeping wine bottles on their side helps maintain contact between the wine and the cork, preventing it from drying out and keeping unwanted oxygen out. This position also helps keep sediment evenly distributed.
- Dark, cool spaces : A wine cellar is ideal, but a closet can also do the job, as long as it stays cool and dark. The ideal temperature is between 12 and 15 degrees Celsius, with relative humidity of 60 to 70%. A basement can often provide the perfect conditions.
- Invest in a wine cellar : For those investing in rare bottles, a temperature- and humidity-controlled wine cellar is essential. These cellars provide the ideal environment for aging, preserving the wine’s qualities over the long term. Modern cellars are also often equipped with anti-vibration systems and UV-protective doors.
- Thermoelectric wine cabinet : For those who can’t afford a wine cellar, a thermoelectric wine cabinet is a good alternative. It offers a stable temperature without excessive vibrations and without the drawbacks of a traditional refrigerator.
- Specialized storage containers : There are also specialized storage containers that can be placed in the home to simulate the aging conditions of a cellar.
Conclusion
In short, while a refrigerator may seem like a practical way to store wine, it isn’t suited to aging. Temperatures that are too low, excess humidity, vibrations, and light can all alter the wine’s quality and evolution. To make sure your wine ages in the best possible conditions, it’s better to invest in a wine cellar or find a cool, dark place for storage. Protecting your precious bottles is well worth it if you want to enjoy a superior wine in the future.
