  text: In the food industry, and especially in wines as products thereof, ethanol
    and sulfur dioxide play an equally important role. Both substances are important
    wine quality characteristics as they influence the taste and odor. As both substances
    comprise volatile matter, electronic noses should be applicable to discriminate
    the different qualities of wines. Our study investigates the influence of alcohol
    and sulfur dioxide on the discrimination ability of wines (especially those of
    the same grape variety) using two different electronic nose systems. One system
    is equipped with metal oxide sensors and the other with quartz crystal microbalance
    sensors. Contrary to indications in literature, where the alcohol content is discussed
    to have a large influence on e-nose results, it was shown that a difference of
    1 % ethanol was not sufficient to allow accurate discrimination using Linear Discriminant
    Analysis by any system. On the positive side, the analyzed concentrations of ethanol
    (about 12 %) did not superimpose other volatile information. So difference in
    sulfur dioxide content gave an accuracy for sample discrimination of up to 90.6
    % with MOS nose. Thus, we are so far partially able to discriminate wines with
    electronic noses based on their volatile imprint.
