The invention relates to a method for improving the filling ability of tobacco, such as cut tobacco leaves, or ribs, or tobacco additives, whereby the tobacco material with an initial water content of up to 15 wt % is treat ed with a gas, comprising nitrogen and/or argon, at pressures from 50 to 1000 b ar with a continuous, or staged compression, followed by a continuous or staged decompression, whereby the compression and decompression steps occur in, either an autoclave, or a cascade-like series of several autoclaves and, finally, a thermal after-treatment of the withdrawn tobacco material. The invention is characterised in that the compression is carried out at a worki ng temperature of over 55 ~C, preferably from 60 to 90 ~C and the final water content of the tobacco is in the range of 8 to 14 wt. %.
