Air-cure tobacco by hanging the tobacco in a well-ventilated barn and allow it to dry over a period of four to eight weeks. Air-cured tobacco is generally low in sugar content, which gives the tobacco smoke a smooth, semi-sweet flavour. Air-cured tobacco leaves usually have a high nicotine content.
