ABSTRACT
The objective of this work was to assess and characterize two clones, 169 and 685, of Sauvignon grapes and to evaluate the wine produced from these grapes. The experiment was carried out in
São Joaquim, SC, Brazil, during the 2009 harvest season. During grape ripening, the evolution of physical-chemical properties, pounds, organic acids, and anthocyanins was evaluated. During grape harvest, ponents were determined for each clone. Individual and total phenolics, individual and total anthocyanins, and antioxidant activity were evaluated for wine. The clones were also assessed regarding the duration of their phenological cycle. During ripening, the evolution of pounds and of physical-chemical parameters was similar for both clones; however, during harvest, significant differences were observed regarding yield, number of bunches per plant and berries per bunch, leaf area, anic acid, polyphenol, and anthocyanin content. The wines produced from these clones showed significant differences regarding position. The clones showed similar phenological cycle and
