PROBLEM TO BE SOLVED: To provide a method for efficiently producing ethanol without requiring a step for concentrating a saccharified liquid. SOLUTION: The method for producing ethanol by saccharifying waste having a high sugar content, fermenting the product and distilling the resultant product, includes subjecting a slurry obtained by adding additive water to the waste having the high sugar content to solid-liquid separation, fermenting the filtrate after the solid-liquid separation by directly introducing the filtrate into a fermentation vessel, converting the residue after the solid-liquid separation into a sugar solution by a saccharifying vessel, and fermenting the sugar solution by introducing the sugar solution into the fermentation vessel.
