Evolution of metal and polyphenol content over a 1-year period of vinification: sample fractionation and correlation between metals and anthocyanins

Tempranillo grape variety (Vitis vinifera) samples obtained from a 0–345-day period of vinification were analysed. Fe, Cu, Zn and Mn were quantified as well as polyphenols and anthocyanins. A good correlation has been found for both Fe and Cu with total polyphenols and anthocyanins. A selected sampl...

Sumario:Tempranillo grape variety (Vitis vinifera) samples obtained from a 0–345-day period of vinification were analysed. Fe, Cu, Zn and Mn were quantified as well as polyphenols and anthocyanins. A good correlation has been found for both Fe and Cu with total polyphenols and anthocyanins. A selected sample was fractionated through an open column, allowing the individual correlation of both Zn and Cu with cyanidin-3-glucoside to be established.
