The identification and quantification of anthocyanins and flavonols was attempted,while the metal content was examined throughout the vinification process and changes were correlated with the polyphenols variations. After the vinification process the wines were stored under modified atmosphere (50% N2, 50% CO2), which in a previous experimental work proved to protect wine against deterioration. Changes in polyphenol and metal content of wines were studied throughout a storage period of 1 year
