We have created a system to feed grapes through the crusher destemmer and pump to fermenter or press via a cooling circuit. This has removed a lot of the manual work of getting grapes from bin to crusher. The grapes are 2009 Hunter Shiraz machine harvested. Since then the system has been further improved. When processing hand picked Hunter Semillon or Hunter Chardonnay grapes the cooling of the "grape must" allows pressing cold which helps a lot with the quality. I prefer all grapes to be hand picked even if it costs a little more.
