Most Common Problems of Glass Wine Cellar

Let's take a look at the most common problems that glass wine cellars face and learn some tips on how to prevent and address them.

1. Heat and Moisture

Glass Wine Cellars Absorb Heat From Your Home | Wine Coolers Empire - Trusted Dealer

The thing is, glass isn't the best material for wine cellars. Glass absorbs and conducts heat much better than insulated drywall, so it can be a bit of a problem when it comes to keeping the temperature consistent.

Think of it this way, the glass acts like a bridge between your climate-controlled wine cellar and the rest of your home. So, if your cellar is at 55 degrees and your home is at 70 degrees, the glass will absorb that heat difference and make it harder for your cooling system to maintain the right temperature. This glass paneling will cool a portion of your home and puts stress on your wine cooling system.

Another issue with glass wine cellars is that they often don't usually have weather stripping on the door. This means that heat and moisture can get into the cellar much more easily than they would in a traditional cellar with weather stripping. It's a small detail, but it can make a big difference. So, when you're planning your glass wine cellar, make sure to include weather stripping on the door to help keep the heat and moisture out.

2. Noise

Noise in Glass Wine Cellars | Wine Coolers Empire - Trusted Dealer

Another thing to keep in mind with glass wine cellars is that glass doesn't do a great job of absorbing sound.

This can be especially noticeable if you're planning to use your cellar as a place to entertain guests or enjoy your wine. So, when you're choosing a cooling system for wine cellars, it's important to consider the noise level and installation type. We'll provide some recommendations below.

3. Temperature Fluctuations

Temperature fluctuations are one of the most significant issues faced by glass wine cellars. These fluctuations can cause the wine to expand and contract, leading to cork failure and spoilage of the wine. This can happen for a variety of reasons like poor insulation, inadequate wine cellar cooling systems, or even just the placement of the cellar.

But, don't worry! There are ways to prevent this from happening. To keep your wine at the ideal temperature, make sure your glass wine cellar is properly insulated and invest in a high-quality, modern wine cellar cooling unit.

4. Humidity

Wine storage humidity is another critical factor, and glass wine cellars are particularly susceptible to humidity issues. High humidity levels can cause mold and mildew to grow on the labels and corks of your wine, while low humidity can dry out the corks, allowing air to enter the bottle and spoil the wine. To maintain proper humidity levels, invest in a wine cellar humidifier or dehumidifier, and monitor the humidity levels regularly.

5. Lighting 

Lighting is another potential problem for glass wine cellars. Direct sunlight or artificial light can cause the wine to become light-struck, leading to spoilage and loss of flavor. Causes of lighting problems may include poor location of the cellar, inadequate window coverings, or insufficient ventilation. To prevent lighting issues, ensure that your glass wine cellar is placed in a location that is not exposed to direct sunlight, and use window coverings or UV-filtering film to block out light.

6. Vibration

Vibration can also be a problem for glass wine cellars, as it can cause sediment to be disturbed, affecting the wine's flavor and aroma. Causes of vibration include heavy foot traffic, nearby construction, or appliances that generate vibrations. To prevent vibration issues, place your glass wine cellar in a location that is away from heavy foot traffic, and keep appliances that generate vibrations, such as washing machines and dryers, away from the cellar.

7. Condensation

Lastly, condensation is another issue that glass wine cellars face with cooling systems. When cold air is blown directly onto the glass, this can cause condensation to form inside your cellar. It can also cause mold and mildew to form on the labels and corks of the wine, which alters the wine's flavor and aroma.

Best Solution for Glass Wine Cellar

No need to worry, we've got you covered with our recommended solutions for glass wine cellars. By addressing these challenges, you can ensure that your wine collection is well-protected and can age and develop its full flavor and aroma.

1. Proper Insulation and Vapor Barrier 

We recommend traditional drywall construction with 2x4 or 2x6 studs. It's important to make sure that the walls and ceiling are well-insulated, with a minimum of R-17 for interior walls and R-30 for ceilings and exterior walls.

Additionally, have a vapor barrier in place to prevent water vapor from entering or leaving the cellar. This will help keep your glass cellar in the best possible condition.

If using glass in your entire wine cellar construction, it’s best to use dual-pane insulated glass to reduce heat transfer and improve energy efficiency. If you have a glass door in your wine cellar, make sure to add weather stripping including the bottom sweep to prevent heat and moisture from entering the cellar.

Pay attention to the joints where the glass panels connect. These areas can often be sources of air leaks, which can negatively impact the overall efficiency of your cellar environment. To prevent this, make sure to seal these joints properly to ensure an airtight seal.

2. Upsize the Cooling System

A glass-enclosed cellar will require a wine cooling system powerful enough to keep the heat out and the moisture levels stable. This means oversizing the cooling system.

A good rule of thumb is to go for a wine cooler unit that's 2-3 times bigger than what you would normally use for traditional wine cellars. And instead of going by the size of the cellar, it's better to choose a system based on its BTU rating. This will ensure that your cellar stays at the right temperature and humidity level.

3. Use Fully-Ducted Wine Cellar Cooling Systems

They offer efficient cooling in addition to being the quietest wine cellar cooling units. Also, make sure the wine room cooler is not directly blowing toward the glass to prevent condensation from forming. Ceiling-mount wine cellar cooling units are also a great choice.
