Excerpt from Curing and Fermentation of Cigar Leaf Tobacco Considerable variation has been found in the total nitrogen content 01 the fresh leaves, as well as in the amido nitrogen content of the cured leaves. The amount of the former may vary in American, Greek, and German tobaccos from 2, 3, or 4 per cent to 8 per cent of the dry leaf. One-third of this and even more can turn into amido compounds in the curing process. Regulation of heat and. Moisture - Further changes, relating to color and navor, -set in with the death of the cells. However, it requires a most judicious regulation of the moisture, temperature, and ventila 'tion of the barn where the tobacco leaves are hung up to obtain those changes which characterize cured tobacco of a superior quality. This curing process may last four weeks or even much longer.2 When the weather is too dry all the chemical changes in the leaves come to a pre mature stop, but on the other hand when it is too moist the danger of mold development arises. In the former case the barns must be eventually kept closed and water introduced, while in the latter case careful application of heat may be resorted to.
