As widely reported in literature, a number of stress factors
occurring during the process, the lack of micro and macronutrients
necessary for yeasts, unsuitable reaction temperatures, too low pH
values, the presence of significant concentrations of inhibitors (ethanol,
phenols, etc.) in the reaction medium, the development of dangerous
microorganisms as well as the alteration of ionic equilibrium can
induce a deep modification of the alcoholic fermentation kinetics [1,2]
