Zanimljivosti
Around 1839 an enslaved man named Stephen accidentally produced the first true bright leaf tobacco. He used charcoal to restart a fire used to cure the crop, and the surge of heat turned the leaves yellow. In India, so-called "white" snuff is made by sun-curing varieties of burley and milling the leaf very finely into a dry, unusually potent powder.
