Pumping Over
A process during the FERMENTATION of red wine in which the juice is pumped from the bottom of the container to the top and then sprayed over the CAP of skins to break it up and keep it wet. By trickling through this mass of skins, the juice picks up even more COLOR, flavor, and TANNIN. Pumping over also helps prevent the growth of undesirable bacteria that might spoil the wine or create off flavors.
