Of the possibilities investigated for alcohol reduction by microbiological and biochemical means, positive results were found for the use of enzymes (glucose oxidase), the use of non-sSaccharomyces yeasts and the dosed addition of must sugar to a yeast suspension. In the case of enzyme utilisation using GOX as well as "non-sSaccharomyces", the application is relatively easy and entails a low to medium financial input. The use of current genetically modified yeast strains did not produce satisfactory results. Legal regulations are necessary for all the processes examined.
