It is important to heal tobacco after harvest and before it can be consumed. Treating tobacco is also known as curing color, because the tobacco leaves are healed in order to change their color and reduce their chlorophyll content.

Histori
Curing tobacco is always a necessary process to prepare the leaves for consumption because, in raw, freshly picked, green tobacco leaves are too wet to burn and smoke. In recent years, traditional maintenance granaries in the United States are no longer in use, as the tendency to use prefabricated metal packaging boxes has become increasingly prevalent. Temporary preservation boxes are often found in locations on tobacco farms.

Process
Curing and subsequent aging allows slow oxidation and degradation of carotenoids in tobacco leaves. It produces various compounds in tobacco leaves that provide preserved dry tobacco, tea, rose oil, or flavorful fruit flavors that contribute to the "smoothness" of the consumed product. Non-age or low quality tobacco are often artificially flavored with naturally occurring compounds. The tobacco seasoning is a significant source of income for the aroma and fragrance industry.
The aging process continues for several months and often extends to the post-curing harvest process.
After the tobacco is healed, it is transferred from the preservation warehouse to the storage area for processing. If the whole plant is cut, the leaves are removed from the tobacco rod in a process called stripping. For tobacco that is cut and drawn, the leaves are then sorted into different values. In the colonial period, tobacco was then "cherished" into a boar for transportation. In bright tobacco areas, weighting is replaced by accumulating "hands" wrapped into loose stacks for sale at auction. Currently, the most healed tobacco is impregnated before sales are made under a pre-sale contract.
Method
Cut the retrieved plants or leaves immediately into the tobacco warehouse (kiln house), where they will be healed. The preservation method varies with the type of tobacco grown, and the design of the tobacco warehouse varies accordingly.
Air
Air-cured tobacco is hung in a well-ventilated vent and allowed to dry within four to eight weeks. Air-cured tobacco is a low sugar, which gives light tobacco smoke, sweet taste, and high nicotine content. Cigar tobacco and air burley.
Fire
Fire-cured tobacco is hung in a large warehouse where hardwood fires are stored in continuous or intermittent low smolders and take between three days and ten weeks, depending on the process and tobacco. Fire curing produces low sugar tobacco and high nicotine. Pipe tobacco, chewing tobacco, and burning tobacco fire.
Flue
Tobacco smoke was originally assembled into tobacco rods, which hung from tier-poles in drying barns (Aus: kilns), also traditionally called oasts. These barns have a chimney coming from an externally fed fire box, heating tobacco without exposing it to smoke, slowly raising the temperature during the curing process. In 1960 the conversion to a gas-fueled system such as Gastobac Burner SystemÃ,® was common. This process will usually take about a week. This method produces high sugar tobacco and has a moderate to high nicotine. Smith's Tobacco Warehouse is an example of a traditional burning tobacco store.
Sun
Sun-cured dried tobacco is found in the sun. This method is used in Turkey, Greece, Bulgaria, Macedonia, Romania and Mediterranean countries to produce oriental tobacco. Sun-cured high tobacco sugar and low nicotine. In India, sun curing is used to produce so-called "white" snuffs, which are smooth, dry, and amazingly potent.
Fermentation
Some tobacco (mainly Cavendish and Perique) are subjected to a second stage of curing known as fermentation or sweat . Cavendish Tobacco undergoes pressurized fermentation in a solution containing sugar and/or flavoring.
