A process for the production of ethanol from sugar- containing raw materials by extraction of the raw materials by means of an aqueous medium, fermentation of the saccharide-containing fermentable extract and distillative processing of the resulting ethanol-containing fermentation liquid. At least part of the water-enriched stillage incurring as a residue at the distillative processing of the fermentation liquid is recycled for extraction in counterflow to the raw materials. In a plant for carrying out the process, the extraction apparatus includes a series of vessels being under atmospheric pressure and connected with its each other, in whose interior a partition wall not reaching as far as to the bottom of the vessel is each provided.
