Abstract
Abstract A method of forming aromatic tobacco by heating the tobacco to a predetermined temperature and then cutting the tobacco while hot, for example, at a temperature such as 140* to 150* F. to thereby obtain improved smoke, aroma and appearance characteristics of the tobacco. The tobacco is moisturized before the cutting so that it manifests a moisture content of 21%-26%. During the cutting the tobacco is maintained under a pressure of 2,000-5,000 pounds externally applied.
