Abstract: The present invention provides a method for efficiently producing ethanol from a lignocellulosic raw material. More specifically, the present invention provides a method for producing ethanol from a lignocellulosic raw material, which comprises a step of performing multiple parallel fermentation while continuously or intermittently adding an additional saccharification enzyme to a fermentation liquid comprising a lignocellulosic raw material, a saccharification enzyme and a yeast so that the physical property value of the fermentation liquid itself is maintained within a preset range.
