Although humidity levels are almost always referred in terms of Relative Humidity, the actual value that is important is the amount of water vapor present in a given volume of air, known as Absolute Humidity. As air will hold varying amounts of water vapor at different temperatures, no discussion
of humidification would be complete without a discussion of temperature and it's effect on absolute humidity. Relative humidity is an easily measured value that relates the measured humidity to the maximum humidity that is possible at that temperature. Thus, 70% RH at 70 ºF is not the same as 70% RH at 80 ºF.
We are aiming to maintain the same amount of water (mgm/liter) around our cigars as seen at 70% RH at 70 degrees F (which is 13.15 mmHg water vapor pressure).
So, to be able to know what is happening with our cigars at temperatures other than 70 degrees F, we must use a table of adjusted relative humidity values to make sure that our humidors keep our cigars in the peak of condition.
Temperature, water vapor pressure and relative humidity required to equal 70% RH at 70 degrees (13.15mmHg).
Water Vapor Pressure
It is not possible to attain an absolute humidity level that will keep cigars from drying out at temperatures below 60 degrees F. This observation will put to rest the fallacy that the refrigerator is a good place to store cigars. Not only do we have to worry about our premium cigars beginning to acquire the flavors from left over foods but the cigars will dry out and become essentially unsmokable. The freezer is an even worse place to store cigars. The humidity becomes virtually zero, and the loss of moisture from cigars will accelerate to produce a bone-dry smoke.
