Active wine cellars are highly insulated and need to be properly constructed. They require specialized wine cellar conditioning and cooling systems to maintain the desired temperature and humidity. In a very dry climate, it may be necessary to actively humidify the air if you live in Palm Springs or Indian Wells, CA, but in most areas this is not necessary. Passive wine cellars must be located in naturally cool and damp areas with minor seasonal and diurnal temperature variations—for example, a basement in a temperate climate. Installing wall stone on the inside and outside of a wine room or cellar helps you in achieving a true passive cellars that will cost you nothing to operate and are not affected by power outages if you live in places like the Midwest or even sometime the east coast of the US.
