A method of treating cut stem tobacco material by expanding the cut stem to provide a first expanded tobacco material having a fill value at least about 10% greater than the fill value of the untreated cut stem tobacco material; intermittently contacting the first expanded tobacco material with a heated surface to provide a second expanded tobacco material with a moisture content of from 0 to about 10% OV and a fill value at least 5% greater than the fill value of the first expanded tobacco material; and (c) adjusting the moisture content of the second expanded tobacco material from about 5% to about 30% OV to provide an expanded product, wherein the fill value of the expanded product is at least 50% greater than the fill value of the untreated cut stem tobacco material when measured at a normalized moisture content of 14.5% OV.
