Wine Bladder presses offer a gentler yet more efficient press with less operator effort and the ultimate in press-control. You will extract more juice and less tannin.
Attach a standard garden hose to the included hose fitting. Water fills up the interior rubber bladder which expands and presses the grapes against the outer stainless steel screen. 35 p.s.i water pressure (2.5 bar) is the maximum pressure you would need to operate.
There is a outer plastic sleeve that is placed over the top of the press to keep the pressed fruit from squirting out. After pressing, the entire stainless basket rotates and can be modified to turn 180 degrees face down for easy clean-up.
