• It improves fermentation and increases the quality of tobacco
  • It provides elasticity of outer sheets
  • It prevents loss of aroma during the storage of finished products
  • It prevents drying and crushing of cigars and cigarettes in warehouses and stores

Tobacco is extremely hygroscopic (absorbs or releases moisture until a balance between tobacco and air is achieved). The air extracts moisture from tobacco if the tobacco is damper than the ambient temperature in which it is located. This is a simple drying mechanism. If the drying of stored tobacco is to be avoided, it is enough to ensure a balance between the moisture content of the air and the desired moisture content in the tobacco.

Recommended values of relative humidity of air in the warehouse and processing of tobacco:

“Walk-In” humidors

55 – 60%

* Fermentation is also improved without presence of mold.

** In order to achieve the desired elasticity of the outer sheets, the air must be saturated with moisture.

*** The appropriate air humidity ensures that cigarettes slightly lose their humidity and that they are stored on a humidity level suitable for packaging. The air that is too dry causes a loss of aroma. The air that is too damp leads to the formation of mold.
