Tobacco is cured to dry and age it in preparation for human consumption. A byproduct of curing is changing the color of the aged leaf, also known as color curing. Tobacco is cured directly after it is harvested in nearly all instances where it is to be used for smoking or chewing. [1]

Curing tobacco has always been necessary to prepare the leaf for consumption because in its raw freshly picked state the green tobacco leaf is too wet to ignite and be smoked, and too acrid to chew. In recent times, traditional curing barns in the United States have been replaced with prefabricated metal curing boxes. Temporary curing boxes are often found on location at tobacco farms.
Curing and subsequent aging allow for the slow oxidation and degradation of carotenoids in the tobacco leaf. This produces various compounds in the tobacco leaves that give cured tobacco its sweet aromatic aroma, characteristic flavor, and degree of "smoothness" to the consumed product. Non-aged[ citation needed ] or low quality tobacco is often artificially flavored with these otherwise naturally occurring compounds. Tobacco flavoring is a significant source of revenue for the flavor and fragrance industry. [1]
Aging continues for a period of months, and often extends into the post-curing process.
After tobacco is cured, it is moved from the curing barn into a storage area for processing. If whole plants were cut, the leaves are removed from the tobacco stalks in a process called stripping. For both cut and pulled tobacco, the leaves are then sorted into different grades. In colonial times, the tobacco was then "prized" into hogsheads for transportation. In brightleaf tobacco regions, prizing was replaced by stacking wrapped "hands" into loose piles to be sold at auction. Today, most cured tobacco is baled before sales are made under pre-sold contracts.
Cut plants or pulled leaves are immediately transferred to tobacco barns (kiln houses), where they will be cured. Curing methods vary with the type of tobacco grown, and tobacco barn design varies accordingly, including the newer use of field-side curing frames. [2]
Air-cured tobacco is hung in well-ventilated barns and allowed to dry over a period of four to eight weeks. Air-cured tobacco is low in sugar, which gives the tobacco smoke a light, sweet flavor, and a high nicotine content. Cigar and burley tobaccos are air cured. [3]
Fire-cured tobacco is hung in large barns where fires of hardwoods are kept on continuous or intermittent low smoulder and takes between three days and ten weeks, depending on the process and the tobacco. Fire curing produces a tobacco low in sugar and high in nicotine. Pipe tobacco, chewing tobacco, and snuff are fire cured. [4]
Flue-cured tobacco was originally strung onto tobacco sticks, which were hung from tier-poles in curing barns (Aus: kilns), also traditionally called oasts. These barns have flues which run from externally fed fire boxes, heat-curing the tobacco without exposing it to smoke, slowly raising the temperature over the course of the curing. In the 1960s conversion to gas fueled systems such as the Gastobac Burner System® [5] was common. The process will generally take about a week. This method produces tobacco that is high in sugar and has medium to high levels of nicotine. The Smith Tobacco Barn is an example of a traditional, flue-cured tobacco barn. [6] Flue-cured tobacco requires an estimated one tree per 300 cigarettes. [7]
Sun-curing tobacco involves simply drying the leaves uncovered in the sun until they are brown and withered. [8] This method is predominantly used in Turkey, Greece, Bulgaria, North Macedonia, Romania and throughout the Mediterranean basin to produce oriental tobacco, [9] however sun-cured tobacco is also produced in India and Africa as well. Oriental sun-cured tobacco is low in both sugar and nicotine but fragrant, herbal, and spicy. It is prized among pipe tobacco blenders for this quality. [10] In India, sun-curing is used to produce so-called "white" snuff from varieties of burley. The sun-cured burley tobacco is very finely milled into a dry powder, and unusually potent. [11]
Some tobaccos such as Cavendish and Perique are subjected to a second stage of curing known as fermenting or sweating. [12] Cavendish tobacco undergoes a process of fermentation under great pressure (often in a large press) and steam. Before being steamed, it is "cased" in a solution which mainly consists of sugar, but can sometimes include flavorings. [13] Perique is special in its process of fermentation, as after it is air-cured, it is traditionally fermented under enormous pressure (via large weights or a hydraulic press) for several months to a year. The process produces a very strong tobacco in both flavor and nicotine, and is prized by pipe tobacco blenders for its uniquely peppery and savory flavors and aromas. [14] [15]
A tobacco pipe, often called simply a pipe, is a device specifically made to smoke tobacco. It comprises a chamber for the tobacco from which a thin hollow stem (shank) emerges, ending in a mouthpiece. Pipes can range from very simple machine-made briar models to highly prized hand-made artisanal implements made by renowned pipemakers, which are often very expensive collector's items. Pipe smoking is the oldest known traditional form of tobacco smoking.
Tobacco is the common name of several plants in the genus Nicotiana of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used in some countries.
A cigar is a tobacco product made to be smoked. Cigars are produced in a variety of shapes and sizes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, for appearance and flavor, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars can come with two or more, highlighting special qualities such as age and origin of the tobaccos used.
A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term cigarette, as commonly used, refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or a herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, different smoking method, and paper wrapping, which is typically white.
Smoking is the process of flavoring, browning, cooking, or preserving food by exposing it to smoke from burning or smoldering material, most often wood. Meat, fish, and lapsang souchong tea are often smoked.
Snus is a Swedish tobacco product and non-tobacco nicotine product consumed by placing a pouch of powdered tobacco leaves or powdered non-tobacco plant fibers under the lip for nicotine to be absorbed through the oral mucosa. Whereas the nicotine in tobacco-based snus derives from tobacco leaves, the nicotine in non-tobacco snus can be either naturally or synthetically synthesized.
Burley tobacco is a light air-cured tobacco used primarily for cigarette production. In the United States it is produced in an eight-state belt with approximately 70% produced in Kentucky. Tennessee produces approximately 20%, with smaller amounts produced in Indiana, North Carolina, Missouri, Ohio, Virginia, Maryland, Pennsylvania and West Virginia. Burley tobacco is produced in many other countries, with major production in Brazil, Malawi and Argentina.
Chewing tobacco is a type of smokeless tobacco product that is placed between the cheek and lower gum to draw out its flavor. It consists of coarsely chopped aged tobacco that is flavored and often sweetened; it is not ground fine like dipping tobacco. Unwanted juices are spat while chewing.
Nicotiana rustica, commonly known as Aztec tobacco or strong tobacco, is a rainforest plant in the family Solanaceae native to South America. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of Nicotiana such as Nicotiana tabacum. More specifically, N. rustica leaves have a nicotine content as high as 9%, whereas N. tabacum leaves contain about 1 to 3%. The high concentration of nicotine in its leaves makes it useful for producing pesticides, and it has a wide variety of uses specific to cultures around the world. However, N. rustica is no longer cultivated in North America, as N. tabacum has replaced it.
Cavendish tobacco is tobacco that has been heat treated with fire or steam and then subjected to heavy pressure in order to produce a sweet taste with a moist texture. American, Dutch, and Danish varieties involve the addition of flavorings; while British Cavendish, commonly known as unsweetened or unflavored Cavendish brings out the natural sugars in the tobacco through pressure applied during the preparation process. Cavendish tobacco is named after Sir Thomas Cavendish.
Nicotiana tabacum, or cultivated tobacco, is an annually grown herbaceous plant of the genus Nicotiana. N. tabacum is the most commonly grown species in the genus Nicotiana, as the plant's leaves are commercially harvested to be processed into tobacco for human use. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 and 2 meters. Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, N. tomentosiformis, and possibly N. otophora.
Perique is a type of tobacco from Saint James Parish, Louisiana, known for its strong, powerful, and fruity aroma. When the Acadians made their way into this region in 1776, the Choctaw and Chickasaw tribes were cultivating a variety of tobacco with a distinctive flavor. A farmer named Pierre Chenet is credited with first turning this local tobacco into what is now known as Perique in 1824 through the labor-intensive technique of pressure-fermentation. It is reported by authorities on tobacco that Perique is based on a variety of Red Burley leaf. The Tobacco Institute says perique has been shipped out of New Orleans for more than 250 years and is considered to be one of America's first export crops.
Latakia tobacco is a sun-dried and smoke-cured tobacco product. It originated in Syria and is named after its major port city of Latakia, though large production has permanently moved to Cyprus due to varying and compounding sociopolitical issues within Syrian borders. It is in the family of fire-cured tobaccos in which the leaves are dried(cured) over burning hard wood. What sets Latakia apart from other fire-cured tobaccos is the use of heavy volumes of smoke from both dried and live material from aromatic woods.
Snuff is a type of smokeless tobacco product made from finely ground or pulverized tobacco leaves. It is snorted or "sniffed" into the nasal cavity, delivering nicotine and a flavored scent to the user. Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made "snuffing" device.
The history of commercial tobacco production in the United States dates back to the 17th century when the first commercial crop was planted. The industry originated in the production of tobacco for British pipes and snuff. See Tobacco in the American colonies. In late 18th century there was an increase in demand for tobacco in the United States, where the demand for tobacco in the form of cigars and chewing tobacco increased. In the late 19th century production shifted to the manufactured cigarette.

The Toscano cigar is a brand of Italian cigars manufactured in Tuscany, Italy. They are made with fermented Kentucky tobacco. The brand was established in the late 19th century. It is an established brand in Italy and also in Switzerland and in Austria.
Smokeless tobacco keratosis (STK) is a condition which develops on the oral mucosa in response to smokeless tobacco use. Generally it appears as a white patch, located at the point where the tobacco is held in the mouth. The condition usually disappears once the tobacco habit is stopped. It is associated with slightly increased risk of mouth cancer.
