Filtration is an essential aspect of the winemaking process. If the filtration is inadequate or contamination is introduced during production, the wine must be refiltered. The refiltration problem at Gallo Modesto is significant, affecting approximately 11% of the filtered product annually. Most refiltrations occur due to high microorganism concentrations. The basic cause for high microorganism growth is the interaction of wine with oxygen and unsanitary equipment. This study explores methods for reducing the amount of refiltrations performed at Gallo Modesto.
