COMPARISON BETWEEN TWO TYPES OF WINEMAKING TANKS FOR THE PRODUCTION OF QUALITY WINES CV. NERO D’AVOLA
AbstractThe aim of this work is to compare two types of winemaking tanks, horizontal and vertical, using Nero d’Avola grapes, in order to assess the capacity of extraction of phenolic compounds that determine the quality of red wines. The study shows that in wine made by horizontal winemaking tanks, both anthocyanins and polyphenols have a higher decrease in time compared to wine made by the vertical type. The higher values of polyphenols found in the horizontal type appear to show that wines produced by this type of winemaking tank have a better quality in terms of health for antimicrobial, antioxidant and antiinflammatory properties of these molecules.
