A method for converting a material comprising lignocellulose or cellulose into a substance convertible with yeast into ethyl alcohol, wherein a mixture comprising 1 part by weight of the material and 0.5 to 5 parts by weight of water is stirred at a temperature of 150 to 270 degrees C. in a vessel closed in terms of pressure in conditions of providing a high shearing force to be pulverized to an average of maximum dimensions of 1 to 20 micrometers, whereby the material is degraded and at least 15% by weight of the cellulose in the material is converted into a substance convertible into ethyl alcohol. It is possible to prepare saccharides for alcohol fermentation from lignocellulose or cellulose by using this method.
