Wine Cellar Construction Basics

Proper wine cellar construction is one of the most important aspects of your project to assure the health of your wine. In order to maintain this ideal environment, your conditioned wine cellar must be constructed according to the specifications below. This will guarantee that your wine cellar cooling unit will be able to provide the proper temperature and wine cellar humidifier will keep the proper humidity levels and prevent possible moisture damage to areas adjacent to the wine cellar. Check your local building codes for more information.
