Although a great number of references, providing a lot of
information on the different aspects of alcoholic fermentation,
are available in literature, it is still difficult to identify the possible
causes of slowing or stuck fermentations even if the change of some
compositional parameters (ex: D-glucose/D-fructose ratio, glycerine
produced/hexoses converted) or an unusual accumulation of
intermediates of sugar catabolism could be assumed as valid signals of
a possible deviation from Saccharomyces metabolic pathways
