Winery work: fining of the wines under the students responsibility
Chemical and sensorial evaluation of the effect of the different fining agents on wines’s quality. Physical-chemical characterization and evolution of the treated wines: chromatic characteristics, total anthocyanins, degree of ionization of anthocyanins, ionized anthocyanins, total pigments, polymerization index, polymerized pigments, total phenols index, wine turbidity. Sensorial analysis. Selection of the best technical solution
