In summary, we have identified several non-Saccharomyces yeast
strains with interesting features in order to reduce alcohol levels in
wine, by taking advantage of their respiratory metabolism. Determination
of RQ values using pH and glucose levels similar to grape must
has been useful but not decisive in this identification. In contrast, we
consider acetic acid yield on glucose, under aerobic conditions, and
the ability to maintain a highly active metabolism in must, as especially
relevant features for this purpose
