Quince-supported biocatalyst, prepared by the immobilization of an alcohol resistant psychrophilic yeast Saccharomyces cerevisiae AXAZ-1 on quince pieces, was suitable for room and low-temperature continuous winemaking. Continuous fermentation was carried out for 46 days without diminution of wine and ethanol productivity (up to 750 and 71 g/l, respectively) which at 5 degrees C was equal to that usually obtained by traditional fermentation at 22-25 degrees C.
