Pipe Smoking Tobacco Introduction covers the 3 basic kinds of pipe smoking tobacco.

Tobacco History is a brief history of pipe smoking tobacco.
When John Rolfe arrived in Jamestown in 1610, he attempted to grow a smokable tobacco leaf from
the small-leafed Nicotiana Rustica strain cultivated by the Virginia Indians. By 1612, Rolfe had
obtained and grown the seed of a large-leafed Spanish Tobacco, Nicotiana Tabacum, a subtropical
plant with a special taste and aroma. The new strain was shipped to England in 1613 and was an
instant success. This new harvest of golden-leaf tobacco saved the Jamestown colony by becoming
its first exportable commodity.

For a time, tobacco was a medium of exchange for the settlers. Through barter, it was used to pay
salaries and secure goods and services. By 1791, tobacco accounted for one-fifth of all American
exports. To this day, it is America's seventh largest cash crop with exports contributing billions
of dollars to the U.S. balance of trade.

Most pipe tobaccos are composed of several different kinds of raw tobacco, and in each raw tobacco there are different grades. More at Tobacco Grades (provides further information on the types and grades.)
