Bright Leaf Tobacco Seed Types
"Brightleaf tobacco is commonly known as "Virginia tobacco", regardless of where in the world it is harvested. Prior to the American Civil War, most tobacco grown in the US was fire-cured dark-leaf. This type of tobacco was planted in fertile lowlands, used a robust variety of leaf, and was either fire cured or air cured.
Sometime after the War of 1812, demand for a milder, lighter, more aromatic tobacco arose. Ohio, Pennsylvania and Maryland all innovated quite a bit with milder varieties of the tobacco plant. Farmers around the country experimented with different curing processes. But the breakthrough did not come until around 1839.
Growers had noticed that sandy, highland soil produced thinner, weaker plants. Captain Abisha Slade, of Caswell County, North Carolina had considerable infertile, sandy soil, and planted the new "gold-leaf" varieties on it. Slade owned a slave, Stephen, who around 1839 accidentally produced the first true bright tobacco. He used charcoal to restart a fire used to cure the crop. The surge of heat turned the leaves yellow. Using that discovery, Slade developed a system for producing bright tobacco, cultivated on poorer soils and using charcoal for heat-curing."
