Summary: This study was conducted to evaluate the acceptance of grape juice elaborated by classical and artisanal extraction methods. The juices were obtained from a blend of varieties Isabel Precoce (80%) and BRS Violeta (20%). Four extraction techniques were performed: Hot Press (HP) - maceration hot and pectolytic enzyme; Cold Press (CP) - maceration at room temperature and the enzyme; Hot Break (HB) - heating to 80 ° C, with temperature reduction, maceration at 60 ° C and enzyme, and a Steam Extraction (EV) - extraction between 80° and 85° C without enzyme. The juices were evaluated by 120 tasters, not trained.
