One of the main types of blended cigarettes, which are made with a mixture of tobacco varieties. The most popular of the blended cigarettes, these are made with a mixture of fluecured, burley, and oriental tobacco. The specific percentage of each type varies from brand to brand, but, generally, flue-cured is around 50 percent of the blend while oriental is the smallest percentage of the blend at around 12 percent.
Those tobaccos in a blended product that are primarily responsible for the aroma and flavor of the cigar, cigarette, or smoking tobacco.
A process by which tobacco is sold by an auctioneer on a bid basis to a group of buyers, as is the case in the United States, Zimbabwe India and Malawi. Today, tobaccos are sold at auction as well as by contract in these markets.

This term refers to a cube of tobacco. Flue-cured tobacco bales weigh approximately 750 pounds each. There are two types of bales for U.S. burley tobacco: unitized bales, which weigh approximately 450 pounds, and farm bales, which weigh approximately 75 pounds. Tobacco is packaged in bales to facilitate storage and/or transport. Internationally, bales vary in size depending on the farming and sales systems.
The string onto which tobacco leaves must be threaded before they can be hung in a curing barn. The space between the leaves varies depending on the tobacco type and curing method.
The tobacco leaf that holds the filler together in a cigar and gives the cigar its shape. In some cases, the binder may be covered by another tobacco leaf called a top binder. The binder or top binder is then covered by the wrapper, resulting in a finished cigar.
Another name for dark tobacco or tobacco that is dark in color and strong in taste. Black or dark tobacco is primarily used in cigars and dark cigarettes.
On a tobacco plant, the extended part of the leaf that is divided from the base to the tip by the stem; its framework is provided by the veins that extend from the stem. This term is used to refer only to the blade itself—it does not include any portion of the stem. In contrast, the term whole leaf is used to refer to both the blade and stem of a leaf. Also known as the lamina or web.
A mixture of tobacco varieties. The purpose of creating a blend is to produce a quantity of tobacco that meets a customer’s specifications of quality, flavor, and aroma.
Most of the cigarettes smoked today are blended, which means they are made with a mixture of tobacco varieties. The main types are American-blend, Oriental-blend, German-blend, English-blend (or Virginia), Maryland, and dark cigarettes.

A term for a large quantity of tobacco.
A type of curing barn used to cure bulked tobacco. Because the leaves are in stacks, rather than hung individually from the rafters, a bulk barn must be sealed so that enough air will pass through the dense piles of tobacco.
Curing loose leaves of tobacco in racks or boxes. This method of curing is only used on tobacco that requires a great deal of artificial heat.
Tobacco leaves held together prior to processing with a tie leaf, string, or raffia. Also known as a hand.
A type of tobacco that is usually air-cured and light brown to deep reddish-brown in color, with an aroma similar to cocoa. There are two types of burley: Filler type is generally light in body and neutral in flavor, while flavor type is similar in weight to flue-cured tobacco and has a stronger flavor.
Someone who purchases tobacco for a leaf merchant. Buyers purchase tobacco to fill specific customer orders and/or to have tobacco on hand for orders that have yet to be placed. Buyers must be able to determine if the quality and quantity of a tobacco purchase will meet the customer’s requirements and acquire the tobacco at a price that will allow the leaf merchant to make a profit when selling the tobacco to its customer.

The color of tobacco is a significant indicator of ripeness and overall quality. Monitoring color changes during ripening, curing, and fermentation plays a significant role in producing high-quality tobacco and tobacco products.
The process of adding moisture to tobacco so that it will be pliable enough to withstand handling, processing, and manufacturing without breaking into smaller pieces. Special care must be taken to avoid over-conditioning, as this lowers the quality of the tobacco.
A process of selling tobacco that involves contracting a farmer’s entire tobacco crop to one specific buyer.
A cigar that has a thick body, a spherical mouth end, and a straight-cut burning end. The name stems from the La Corona cigar factory in Havana, Cuba, which was the first to manufacture cigars with these characteristics.

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.
One of four main methods of curing, which involves removing all of the natural sap and moisture from tobacco leaves. As its name suggests, this particular method of curing involves exposing tobacco to the heat and smoke of open fires; doing so allows the leaves to absorb the aromatic substances in the smoke, which will in turn affect the tobacco’s taste. The type and age of the wood, as well as the duration of the tobacco’s exposure to the smoke, all affect the tobacco’s taste, which is why these factors vary depending on the end-product that is desired.
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 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. The process generally takes about a week. This method produces cigarette tobacco that is high in sugar and has medium to high levels of nicotine.
A type of tobacco that is cured with artificial heat, after which it ranges from light yellow to dark orange in color and possesses a sweet aroma. It is sometimes referred to as bright leaf or Virginia tobacco.
One of four main methods of curing, which involves removing all of the natural sap and moisture from tobacco leaves. This method of curing uses only artificial heat, such as that provided by oil or petroleum. Flue-curing barns are outfitted with pipes that supply the heat and fans that circulate the heat for even distribution.
On a burley tobacco plant, the groupings of leaves that are closest to the ground. They are typically thinner and drier and, subsequently, often used as cigarette fillers.
A whitish spot on tobacco leaves that gives the tobacco a ripe appearance; the spot is actually the result of a disease.
A method of preparing cigar filler that involves removing the stem of a tobacco leaf in such a way that the two halves of the leaf remain joined at the top; this is said to resemble a frog’s legs, hence the name. The resulting “frog-strips” are used as long filler in cigars.
Using chemicals to control and/or eliminate insects. When tobacco is stored, the storage facility must be fumigated to protect the tobacco from the damage insects can cause.
G
One of the main types of blended cigarettes, which are those made with a mixture of tobacco varieties. These are similar to American-blend cigarettes, but more oriental tobacco is used in the blend. Also, these cigarettes have a milder taste because the tobacco is not as heavily cased and flavored as in American-blend cigarettes.
A symbol, letter, number, or some combination of the three, which is given to tobacco as an indicator of its quality. The tobacco’s stalk position, color, texture, elasticity, and leaf size are among the factors taken into account when determining its grade. B4F, which signifies “fair quality orange leaf,” is an example of a grade.
Assigning pre-defined symbols, letters, or numbers to tobacco as an indicator of its quality. The tobacco’s stalk position, color, texture, elasticity, and leaf size are among the factors taken into account in the grading process. Most tobacco is graded before it is sold; the grade it receives determines (in part) the price a buyer will be willing to pay for the tobacco. Manufacturers and leaf dealers also have their own grades that are used internally.
The uppermost leaves of U.S. flue-cured, burley, or dark air-cured tobacco that are still green in color after drying has occurred.
1) Tobacco that has not yet been re-dried or processed.
2) Tobacco that has not ripened and been properly cured, and consequently remains green in color even after processing has occurred. Sometimes referred to as crude tobacco.

h
A group of five to 30 tobacco leaves held together prior to processing with a tie leaf, string or raffia. Also known as a bundle.
The process of collecting tobacco leaves from the field at the time when leaf maturity has reached its desired stage; harvesting can be done by either manual or mechanical means. Flue-cured and oriental tobaccos are harvested in stages, meaning that individual leaves are removed from the stalk as they ripen, rather than all at once, a process called priming. (The leaves generally ripen from the ground up.) Harvesting burley tobacco can be done in stages or by cutting the entire stalk near the ground and removing all of the leaves at the same time; the process used is generally determined by the climate conditions of the growing region.
A round, wooden container used to hold tobacco while it is transported, stored, or aged. Cardboard boxes and tersa bales are other packaging containers that serve the same purpose as hogsheads.
i
A term used to describe tobacco that has not reached its peak of ripeness in the field.

3) In fire-cured and dark air-cured tobacco, a general term for all of the leaves located in the top third of the tobacco plant.
Tobacco that is cured primarily with natural rather than artificial heat and is typically brown or light brown in color. In contrast to dark air-cured tobacco, which is fermented, light air- cured tobacco is not fermented at all. Also known simply as “air-cured tobacco.”
As its name suggests, loose leaf is tobacco that has not been grouped together in bundles; it is usually in the form of a bale or pile.
A method of selling tobacco in which the tobacco is laid out in piles on the auction floor for inspection by potential buyers; it is popular because it eliminates the expensive and time- consuming task of bundling the tobacco or tying it in hands before it is sold.
1) On a flue-cured tobacco plant, the second grouping of leaves from the ground.
2) The largest leaves on a burley tobacco plant, located near the middle of the stalk.

Water or other liquid diffused in a small quantity as vapour, within a solid, or condensed on a surface.
The amount of water within tobacco leaves. High moisture content gives the leaves elasticity, whereas low moisture content makes the leaves brittle. For this reason, the moisture content of tobacco is carefully controlled so that handling, storing, and manufacturing does not detract from the tobacco’s quality or cause it to break into smaller, less desirable pieces. Moisture content is essential to the fermentation process.
n
Tobacco that has been deceptively packaged so that only high-quality leaves are visible, and the presence of poor-quality leaves and/or non-tobacco-related material is concealed.
Nicotine is a chiral alkaloid that is naturally produced in the nightshade family of plants and is widely used recreationally as a stimulant
and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve
withdrawal symptoms.
Any material other than tobacco that is inadvertently included with tobacco leaves, such as stones, glass, string, pieces of metal, etc. Removing non-tobacco related material during processing is called picking the tobacco.

A subdivision of the lugs on the U.S. flue-cured tobacco plant, primings are the leaves located closest to the ground. Because of their proximity to the ground, these leaves often come in contact with sand and soil and, consequently, must be cleaned before they can be processed. Also known as sand leaves.
The area in a processing facility where (processed) tobacco is packaged and weighed prior to being stored or shipped to a manufacturer.
A general term for all of the processes applied to tobacco after it has been cured and before it is used in the manufacture of tobacco products. Processing involves various stages, including blending, threshing, re-drying, and packaging.
r
Tobacco that has been cut into fine strips for use in cigarettes. Also known as cut rag.
Recently harvested tobacco that has not yet entered the curing phase.
Tobacco in which a pre-determined moisture content has been obtained in the leaves by the re-drying process.
One of the stages in tobacco processing, the purpose of which is to obtain a uniform moisture content specified by the customer. Re-drying involves removing moisture from the tobacco leaves by applying heat and then injecting the leaves with steam until a pre-determined moisture level is obtained.
Prior to being purchased, tobacco is given a grade that serves as an indicator of its quality. Once purchased, the tobacco is sent to a processing facility where it is graded again, a process known as re-grading. The purpose of re-grading is to maintain consistency and ensure that the quality is uniform throughout, especially with respect to customer blends.
A significant amount of the shredded brown innards of most modern cigarettes is a paper product called “reconstituted tobacco” or “homogenized sheet tobacco,”
which is made from a pulp of mashed tobacco stems and other
parts of the tobacco leaf that would otherwise go to waste.
Paper-like sheets of tobacco comprised mainly of scrap and stems. Reconstituted tobacco is produced by a variety of methods, all of which have a single purpose: to allow cigarette manufacturers to make the most efficient use of their tobacco by utilizing scrap and stems instead of discarding them. The paper-like sheets of reconstituted tobacco are then cut into strips and used in cigarettes.
On a burley tobacco plant, the second grouping of leaves from the top.
A process generally reserved for dark tobaccos that will be used in pipe mixtures or dark cigarettes. Roasting controls the moisture content of the tobacco and enhances the aroma.
The name given to cigarettes that are made by hand with cut tobacco and cigarette papers; they do not have filters.
A processing phrase used to describe a blend of tobacco that includes leaves from all of the different stalk positions on a tobacco plant. Because the quality of a leaf is partially determined by its position on the stalk, a run of the crop blend contains a mixture of various qualities. Creating a run of the crop blend is expeditious and lowers processing costs, thereby making the blend cheaper for customers.
Roll-your-own cigarettes refer to cigarettes made from loose tobacco also called shag and rolling paper. Factory-made cigarettes are called tailor-made cigarettes.
s
A small quantity of tobacco (around two kilos) typically pulled from the process after the re- drying operation and compressed into a block measuring approximately 13 inches wide by 17 inches long by 4 inches thick. The purpose of a sample is to provide a representation of the overall quality and color of the tobacco being processed and to ensure consistency and uniformity within the blend.

The process of threading tobacco leaves onto a string or piece of twine so that the leaves can be hung up for curing. Using a needle, the stem is pierced near the base of the leaf and the string is then pulled through the hole. The spacing of the leaves on the string varies according to the type of tobacco and curing process. For the most part, stringing is done by hand.
1) The process of removing stems from tobacco leaves; it can be done by hand, as it is for cigar wrappers, or by machine, as it is for cigarette tobaccos. Also known as stemming.
2) The process of removing tobacco leaves from the stalk; primarily associated with burley tobacco.
Long pieces of leaf that have been threshed or cut away from the stem. At this point, the strips will be blended, compressed, and cut to produce rag.
Removing suckers from a tobacco plant; this can be done by hand during harvesting or, at an earlier stage, by cutting the suckers or spraying the plant with a chemical that inhibits the growth of suckers.
Side shoots that grow after the flowering head of a tobacco plant has been removed. Because suckers rely on the main plant for water and minerals, their growth can lower the quality of the main leaves. Suckers are removed when the quality of the plant justifies the labor and expense needed for their removal. They can be removed by hand or with the use of chemicals.
Sun-cured tobacco dries uncovered in the sun. This method is used in Turkey, Greece, and other Mediterranean countries to produce oriental tobacco. Sun-cured tobacco is low in sugar and nicotine and is used in cigarettes.
One of four main methods of curing, which involves removing all of the natural sap and moisture from tobacco leaves. This method of curing involves exposing tobacco leaves to full sunlight, thereby drying the leaves completely. All oriental tobacco and certain types of Virginia tobacco are sun- cured.
t
A term for loose tobacco leaves that have been randomly layered to form a bale or package. Straight-laid leaves, in contrast, are packed in rows with all of the stems facing the same direction.
A chemical substance made when tobacco is burned. Tar contains most of the cancer-causing and other harmful chemicals found in tobacco smoke. When tobacco smoke is inhaled, the tar can form a sticky layer on the inside of the lungs. This damages the lungs and may lead to lung cancer, emphysema, or other lung problems.
A specific type of import quota that allows a certain quantity of imports at a low tariff rate and subjects imports above that quantity to a very high tariff rate. In the past, imports of leaf tobacco into the United States have been subject to tariff-rate quotas.

A large cube of packaged tobacco; the head and base are wooden and the sides of the cube are wrapped with a clear plastic material. Other containers used to package tobacco include wooden hogsheads and cardboard boxes. The word tersa is an acronym for Tabaco en Rama S.A. , the Mexican company that first developed this type of packaged bale.
A general term for tobacco leaves that grow on the lower half of the stalk; as their name implies, these leaves are thinner than the bodied tobacco that grows on the upper portion of the stalk.
A machine used in tobacco processing facilities to cut the blade of the leaf away from the stem.
A stage in tobacco processing that involves cutting the blade of the leaf away from the stem with a machine called a thresher, resulting in fairly small pieces of leaf blade suitable for use in cigarettes. The threshing process is a key operation in achieving particle size distribution of re-dried tobacco.
A tobacco leaf that is used to tie several leaves together at the base of their stems. Once tied together, the leaves are called a hand.
The filter and tobacco rod are held together by tipping paper, often with an imitation cork pattern printed on it using ink. This paper may also have holes in it to admit air.
