SIMURG
pumping over
EN
c. n.
Wine-making operation involving the circulation of fermenting red wine with the grape skins. 1
Generally, pump-over's are more gentle and shorter when the grapes first go into the tank. At the start of fermentation it is effective, it is less so when done towards the end of fermentation. It is at this stage where the colour is slowly coming out of the skins and there isn't any heat or alcohol to help with extraction. Once the fermentation begins, the pump-over's become more frequent and longer in an attempt to pull out the best of the flavours by moving larger volumes of juice through the warm skins but the warmer it is, the faster the fermentation progresses and the less time it leaves to get all that the grapes have to offer. It can be common practice to pump-over a third to a half of the tank each time. 2
In the winery, a Must Pump is used to transfer the juice and skins of the grape, whether it be to the fermenter from the crusher/destemmer, or during the ferment to pump the fermenting wine over and break up the cap. 3
