Wine Cellar Cooling Systems – How to Build A Cool One

The cellar cooling systems are specifically designed to maintain a constant temperature between 55 and 57 degrees Fahrenheit and humidity levels between 50 and 70 percent. Proper humidity levels will keep the corks sufficiently moist and swollen, ensuring a firmer seal while the proper temperature will moderate the aging process of your wine.

Always remember:

• If the humidity is too low, the corks dry out, thus allowing air to enter the bottle and if oxidation occurs, the wine will surely be ruined.

• If the humidity is too high, you run the risk of mold forming on corks, labels, and bottle racks.

• If the temperature is too cold, the wine becomes sluggish and would end up with a flat taste rather than fruity and sparkling.

• If the temperature is too high, you run the risk of cooking the wine and aging it prematurely.

Ideally, however, the basement room should be precisely designed and built with the right conditions for these temperature and humidity variables to the function.

The wine room

Before installing a wine refrigeration system, make sure the room is sealed against steam and properly insulated.

• All walls and ceilings must scale with a vapor barrier on the "warm side" of the walls. 6 or 8 mils plastic sheeting is highly recommended.

• Interior walls must be insulated with a minimum of R-19. We recommend the use of a rigid foam board. Also, all cracks should be filled with expanding spray foam.

• All walls have a moisture-resistant green board finish.

• Doors must be solid wood and / or insulated and weatherstripping is vital for a tight seal.

• Glass must be double pane with a minimum 1/2 "gap.

• Lighting should be of low power.
