Abstract
A feed containing a sterilie aqueous solution of fermentable sugar and minor amounts of sugar oligomers and/or sugar repolymerizates is continuously converted by fermentation to dilute aqueous ethanol ("beer") in a series of agitated fermentation vessels employing at least two strains of yeast, the first of which provides relatively high rates of conversion of the fermentable sugar to ethanol and the second of which provides relatively high rates of conversion of the sugar oligomers and/or sugar repolymerizates to ethanol.
