Canadian Virginia Tobacco \ Tobacco Types
Flue-cured is also known as Bright and Virginia by the world trade. It is used almost entirely in cigarette blends. Some of the heavier leaves may be used in mixtures for pipe smoking. Some English cigarettes are 100% flue-cured.
Flue-cured leaf is characterized by a high sugar: nitrogen ratio. This ratio is enhanced by the picking of the leaf in an advanced stage of ripeness, and by the unique curing process which allows certain chemical changes to occur in the leaf.
Cured leaves vary from lemon to orange to mahogany in color. The leaves are relatively large with the largest at midstalk. A well grown plant will be topped at a height of 39 to 51 inches with 18 22 - harvestable leaves.
Burley is light air-cured type derived from the White Burley which arose as a mutant on a farm in Ohio in 1864. Burley is used primarily in cigarette blends. Some of the heavier leaf is sued in pipe blends and also for chewing.
Cured burley leaf is characterized by low sugar content and a very low sugar to nitrogen ratio (high nicotine). This is enhanced by high N. fertilizer, harvesting at an early stage of senescence, and the air curing process which allows oxidation of any sugars
which may have occurred. Burley has a tremendous capacity to absorb flavorings (25% of its own weight vs. 7 8% - for flue-cured).
Burley is produced in around 55 countries but only a small amounts in over 1 2 / of these. The main producers and trades are the U.S., Italy, Korea, Brazil, and Mexico. In the U.S. production is in Kentucky, Tennessee, Ohio, Virginia, North Carolina, West Virginia and Missouri.
The dark air-cured term encompasses a number of types used mainly for chewing, snuff, cigar, and pipe blends. Most of the world production is confined to the tropics.
These are heavy type leaves, highly fertilized and topped low to around 10 12 - leaves. Dark air-cured leaf is high in nicotine and used in chewing and snuff and some pipe mixtures. The plants are stalk cut.
Oriental tobacco gives a mild smoke with very characteristic aroma. Resins, waxes and gum exuded by glandular hairs (trichomes) furnish the aroma. Nicotine is low averaging around 1.0%.
Oriental leaf is characterized by its small size, leaf length is 3 10 - inches and is 2 3 - times the width. Average plant heights are 3 5 - ft. The leaves are hand primed, normally sewn on a string, and are dull yellow to rich brown in color. The leaves are sun- cured.
