Why Climate Control Is Important In Wine Cellars

Wine is a delicate and complex product that requires careful handling and storage to maintain its quality. For wine enthusiasts, collectors, and producers alike, understanding the significance of climate control in wine cellars is essential. Ask any seasoned wine aficionado and they’ll agree: climate control is an important step in maintaining a healthy wine cellar. Subtle nuances in temperature and humidity can ruin an otherwise perfect bottle, or barrel, of wine. To learn more about this phenomenon and how to prevent it, keep reading.

How Well Are You Controlling Wine Cellar Humidity?

Most likely, you keep your commercial wine cellar above ground – despite many in the past being built underground. You already know a wine cellar needs to stay cool in order to gain the best results. Generally, this means maintaining the temperature at around 55F.

Humidity can become a hidden problem if you’re not properly monitoring it. Your wine cellar humidity could be affected by some hidden ventilation issues that could affect the cork in all the bottles – as well as, the oxygen in the wine.

How does the wine cellar humidity affect the wine’s oxygen and cork quality? It’s time to take a look at the facts and find out what’s really happening if not readily apparent to the eye.

Why Climate Control is Essential

Traditionally, cork has been used to seal bottles of wine. Even though some producers have moved to using screw tops, purists argue that corks allow wine to breathe and mature effectively. Wine climate control and humidity control is important, since low levels of moisture in the air can cause corks to dry out. This can lead to problems with sealing. Wines of a certain quality are best stored at precise temperatures, and humidifier systems enable manufacturers, distributors and private collectors to keep their supplies under the best conditions.

Preservation of Wine Quality

Wine is sensitive to changes in its environment. Factors such as temperature fluctuations and humidity levels can significantly affect its flavor, aroma, and overall quality. Proper climate control helps preserve the integrity of the wine over time.

  • Temperature Stability: Wine should ideally be stored at a consistent temperature between 50°F to 59°F (10°C to 15°C). Fluctuations outside this range can lead to premature aging or spoilage.

  • Humidity Control: Maintaining the right humidity level (between 60% and 70%) prevents corks from drying out or becoming overly saturated, both of which can compromise the wine’s quality.

Preventing Oxidation

Oxidation occurs when wine is exposed to air, leading to undesirable flavors and aromas. A stable environment minimizes the risk of oxidation by ensuring that bottles are sealed tightly with healthy corks. Proper climate control reduces the chances of air infiltration, preserving the wine’s intended profile.

Thankfully, there are some steps you can take to protect your wine from the destructive effects of humidity-caused oxidation. One simple yet effective preventive measure is to store your wine bottles on their side. Doing so exposes the interior section of the cork to the wine, giving it a natural barrier of protection against drying out. This alone isn’t going to protect your wine corks from excessively dry air, however, so you should take additional measures to protect your investment.

The Role of Humidity in Wine Cellars

Another element to consider when storing wine in a cellar (or any other area) is humidity. If there’s not enough moisture vapor in the air, the wine bottles’ corks may dry out and even crack. This isn’t going to happen overnight, but months of storing wine in a low-humid environment can and will damage the cork. And when the cork is damaged, it will allow air to enter the wine; thus, promoting the destructive effects of oxidation.

Ideal Wine Storage Humidity

The most important thing when it comes to wine storage is regulating humidity. It is important to have ideal wine storage humidity so that it can provide you with a better taste. In addition to this, it is important to keep on controlling the humidity now and then so that you can protect the wine from change in taste. At Smart fog, you will be provided with all the information that you need when it comes to controlling the humidity.

Humidity plays a vital role in wine storage. The right humidity level ensures that corks remain moist and intact, preventing spoilage due to oxidation.

  • Too Low Humidity: If humidity falls below 50%, corks can dry out, leading to shrinkage and potential exposure of wine to oxygen.

  • Too High Humidity: Excessive moisture can lead to mold growth on corks or labels, compromising both aesthetics and quality.

The Way Low Humidity Affects Wine Corks

Having low humidity ultimately affects the oxygen level inside your wines. Unfortunately, this could end up ruining the full potential of the wine’s quality. The problem is that low humidity can dry out natural materials in your cellar. As such, the cork you use could dry out and begin to shrink.

When the cork shrinks, it allows air into the wine bottle where you could experience what’s called cork taint.

Imagine this happening to all of your wines after months of hard work. Your entire wine collection could ruin and turn into a major business disaster.

High Humidity Can Affect Corks and Surrounding Surfaces

Don’t forget about high humidity and the issues it brings. When humidity goes high, you’ll start to see mold developing on surfaces where it shouldn’t. This includes mold on all your wine corks, hence affecting the cork’s quality.

Additionally, mold could ruin the labels on all the wine bottles and start to encroach on the walls or ceiling. Workers who spend time working there could breathe the mold and create bronchial illnesses.

These are just a few of the potential issues you will face unless you find some way to maintain relative humidity in your wine cellar without relying strictly on your main cooling system.

Controlled Humidity Solutions for Wineries

To achieve optimal humidity levels in wine cellars, various solutions are available:

  1. Humidifiers: These devices add moisture to the air, maintaining a stable humidity level. SmartFog offers advanced humidification systems that provide precise control over moisture levels without oversaturation.

  2. Dehumidifiers: In cases where humidity exceeds the ideal range, dehumidifiers can help remove excess moisture from the air.

  3. Climate-Controlled Wine Cabinets: For smaller collections or limited spaces, climate-controlled cabinets provide an all-in-one solution for temperature and humidity management.

Wine Cellar Cooling Systems

Wine cellar cooling systems are created to mimic the same conditions found in a wine cellar located deep underground. For optimal wine aging conditions, wine cellar cooling systems should keep the temperature steady at 50 to 55 degrees Fahrenheit during the entire aging process (which can be years). If the system can also regulate the humidity of the wine cellar, another important factor in aging is taken care of.

Temperature Management

The single most influential element in the long-term storage of wine is temperature. When wine is stored in environments warmer than 72 degrees Fahrenheit, there’s a high chance of it spoiling. The warmer temperatures promotes new chemical processes known as oxidation. As the oxidation occurs, it transforms the existing compounds to create additional chemicals, some of which may possess a bitter or sour taste.

Maintaining a consistent temperature is as vital as managing humidity. Wine cellar cooling systems are designed specifically for this purpose:

  • Cooling Units: These systems regulate temperature within wine cellars by circulating cool air evenly throughout the space. They prevent hot spots that could adversely affect wine quality.

  • Thermal Insulation: Proper insulation helps maintain stable temperatures by minimizing heat exchange with the external environment.

So, what’s the proper temperature in which to store wine? It really depends on the particular variety, as white wines are generally stored at a cooler temperature than reds. Familiarize yourself with the different varieties to find out which temperature is best suited for your wine. A climate between 50 and 59 degrees Fahrenheit may work well for most white varieties, but red wine may store better in a slightly warmer climate of 55 and 64 degrees.

Integrated Systems

Modern wine storage solutions often integrate both cooling and humidification systems for comprehensive climate control. This integration ensures that both temperature and humidity are monitored continuously, providing a stable environment for aging wines.

Essential Accessories for Wine Cellars

Good wine cellars need more than racks for holding bottles or stout oak barrels – humidifiers make essential wine cellar accessories. The right temperature ensures that wine matures properly and does not become oxidized to the point that it is like vinegar. By keeping ambient humidity levels consistent, wine-makers and connoisseurs can ensure that their wines keep well. If corks are kept under humid conditions, there is no chance of their drying out, thus effective sealing is ensured.

Humidifiers as Essential Accessories

When setting up a wine cellar, investing in high-quality humidifiers is essential. They not only maintain ideal humidity levels but also enhance overall air quality within the cellar. Features to look for include:

  • Automatic Controls: These allow for real-time monitoring and adjustments based on environmental changes.

  • Energy Efficiency: Look for models that consume less energy while providing effective humidification.

Additional Accessories

Other essential accessories include:

  • Thermometers & Hygrometers: Monitoring tools that help track temperature and humidity levels accurately.

  • Wine Racks & Shelving: Proper organization aids airflow around bottles, contributing to even temperature distribution.

Finding the Right Wine Storage Area

Choosing an appropriate location for your wine cellar is crucial for successful long-term storage. Considerations include:

  • Temperature Stability: Avoid areas with significant temperature fluctuations such as garages or attics.

  • Humidity Levels: Ensure that the chosen space has natural humidity control or plan for mechanical solutions.

How it Works?

Smart Fog’s (formerly DryFog.US) Fogger supplies high-humidity “dry fog” with droplets of 4.2 microns in diameter. The droplets evaporate into the air before reaching the ground. No free water collects on the barrels and the storeroom floor stays dry.

The Smart Fog System has a large non-clogging orifice needing minimal maintenance. The HumiSense Humidistat uses optical technology to control high humidity up to 95-98% RH – where other humidity meters get stuck. It allows full computer control and tracking of the humidity level in the storeroom.

High humidity reduces evaporation and reduces the need for topping. This table shows the benefits of increasing relative humidity:

Reduced topping means less labor and less chance of mixing batches.

Humidity Solutions for Wineries

The barrels remain dry, preventing mold. High humidity (water vapor in the air) is sometimes confused with wetness (freestanding water on a surface). Mold can only form in freestanding water, not high humidity. The high humidity reduces evaporation without danger of mold, and helps preserve the barrels.

Easy installation and low maintenance make the Smart Fog the only choice for “dry fog.” The Smart Fog System’s large 1.5 mm orifice won’t clog like pinhole foggers, so easy annual maintenance is sufficient.

Conclusion

Effective climate control in wine cellars is indispensable for preserving the quality and integrity of wines over time. By understanding the importance of both temperature and humidity management, along with utilizing modern technology such as humidifiers and cooling systems, wine enthusiasts can create an ideal environment for their collections. Whether you’re a casual drinker or a serious collector, investing in proper climate control will ensure that your wines age gracefully and provide enjoyment for years to come.

If you really want to ensure your wine cellar is safe and suitable for long-term storage, you should invest in a humidifier. These devices are designed to monitor the relative humidity (RH) of the surrounding air, and when necessary, release moisture vapor. You can rest assured knowing that your wine is safe from the effects of dry out with a proper humidifier in place.
