Passive vs Active Wine Cellars
Passive cellars
A passive cellar relies on the natural temperature of a below grade space. In climates with hot, humid summers like the Chattanooga area, few spaces stay cool and stable enough all year without help.
Active cellars
An active cellar uses insulation, a vapor barrier, and a dedicated cooling unit to hold conditions steady regardless of season. Most collectors in the region choose active cooling.
Testing a space
If you are considering a passive cellar, place a recording thermometer and hygrometer in the space for a full summer before building.
Hybrid approach
Some homeowners start with a well insulated room and add cooling later. If you plan that way, run the electrical and leave space for the unit during construction.
