Why “Seal” my wine cellar? – Custom Wine Cellars Texas

Why do I need to “Seal” my wine cellar?

Only this week I was confronted by a builder in Texas who was showing me the room that he was turning into a custom wine cellar for his customer.

He mentioned he knew about adding the correct vapor barrier and insulation. Then, in the next breath, he said “and I am leaving ½” open below the door so that the room gets good air circulation!”

 Air circulation coming from the next room in your home into your wine cellar is exactly what you do NOT want.

Your wine cellar must be sealed like a package. See How to Build Your Wine Cellar. The reason for the vapor barrier is to insure that the temperature and humidity inside the room, controlled by your wine cellar cooling units, is kept at a lower temperature and a higher humidity than in the rest of your home.

To age and preserve wine properly you need to maintain the very stable temperature of 55 to 60 degrees and 50 to 70 percent humidity inside you wine cellar. Leaving a gap under the door allows the cold air to escape and warm air to enter the room, creating difficulty maintaining the correct temperature and humidity. All air going into our coming out of the room should be going through the wine cellar climate control system you have chosen.

Yes, it is possible to maintain the room’s temperature and humidity with this gap. However, you will need a larger wine cellar cooling unit and your unit will run longer, causing an increase in expense to the homeowner’s electric bill.

The gap under the door is the most often cause of cooling loss in a wine cellar!

An easy remedy is to install an exterior door with the same weather stripping you would use if the door were to the outside. Another remedy is to install a door with an automatic door bottom. The doors offered by the award winning Wine Cellar Specialists have the option of the wood threshold or the automatic door bottom at no additional charge. This is highly recommended.

Wine Cellar Design Basics – Remember:
1. Seal any gaps.
2. A vapor barrier is absolutely necessary.
3. The more insulation, the better.
