A method and an apparatus for determining the filling capacity of tobacco are described. A predetermined quantity of tobacco (R) is filled into a volume of known cross-section, closed on one side by a movable plunger (2), and the length of the tobacco column and the force acting on the tobacco via the plunger (2) are measured as a function of time. The data are acquired and processed automatically by at least one computer while the tobacco is being packed into packaging containers (22A) by means of a press, or during an additional pressing by a press after packing. The length of the tobacco column is determined from the measured (52, 54) distance covered by the movable plunger (2) of the press which compresses the tobacco (R) and in doing so moves it into the packaging container (22A), or which carries out the additional pressing of the tobacco. The force acting on the tobacco is measured from the pressure (57) required to drive the plunger (2), or from the supporting force (56) required to hold the packaging container (22A), or from the force occurring at the plunger or its drive elements. Additional parameters governing the value of the filling capacity are determined in independent measurements (60, 62) and fed into the computer. The method is preferably applied to leaf tobacco.
