operate wine pumps
Connect pumps between wine tanks and turn valves to pump wine from one tank to the other. Pump the wine from fermenting and fortifying tanks to cooling tanks, then on to clarifying tanks when cooled, and add appropriate chemicals to wine. Pump the clarified wines through filtering tanks and a pasteuriser. Pump the pasteurised wine through another filtering device to collect sediment and precipitates. Finally, transfer the finished wine into tanks in the bottling room.
