COOLING UNIT BUYING GUIDE

The Difference Between Wine Cellar Cooling Unit and an Air Conditioner

Customers are always asking us why can't they just put a regular window AC in their wine cellar, or just have a duct from their home Central AC run into their wine cellar? It's a great question as you would think as long as the room is a little cool it would be fine. However there are a few large distinctions between how these two types of units function. Your regular home air conditioners are meant to go down to around 65 degrees, possibly 60 at the lowest. But wine is meant to be stored at around 55 degrees in order to age and evolve properly. So even though 60-65 feels cool, and is the appropriate serving temperature for red wine, it is still a little warm for long term storage and can speed up the aging process.

But many people also feel that 60 is close enough to 55, and if they are not aging their wines for extended periods of time (more than a few years) that the temperature difference won't really affect the wines. If it was just a matter of temperature that could possibly be the case. But as important as temperature is humidity. Standard AC units are built to cool the air quickly and to draw all of the humidity out of the air so that you and I are comfortable in a room. That is about the worst thing you can do for your wine. The humidity helps to keep the corks moist, as if they dry out and air gets into the bottle, you have just turned your expensive bottle of wine into an expensive bottle of vinegar.

Wine Cellar Cooling Units are designed to cool the air at a much slower rate in order to maintain the humidity in the room. In certain units you can even add a humidification component to help raise the humidity if the wine cellar is in a dry area. So it is really the combination of the wine cellar cooling unit's ability to cool down to those lower mid 50 degree temperatures and doing so without drying out the air that makes them quite different then your standard air conditioning units.
