Tobacco can

The present invention relates to methods for hindering formation of tobacco-specific nitrosamines during processing of dark fire tobacco, as well as a facility in which at least portions of these methods may be conducted. According to the present invention, dark fire tobacco that has been harvested and that is generally green and/or yellow is exposed to an uncontrolled, yet active, ambient airflow so as to provide a substantially aerobic environment about the tobacco. This exposure of the dark fire tobacco to the ambient airflow may be done until the tobacco is substantially brown and/or substantially free of enzymatic activity. Subsequently, the tobacco is exposed to gaseous emissions (e.g., smoke) from combusting sawdust/wood. This step may be conducted at least until the tobacco exhibits a moisture content of no more than about 16% and/or until the tobacco exhibits a gloss or shine on a surface of the tobacco.
