The grape press has a funnel (4) with two corrugated rollers (5), whose horizontal parallel axes rotate in opposite directions, and a press (1) with a helicoidal screw (6). The funnel is mounted directly over the feed opening for the press so that the grapes crushed by the rollers are driven by the helicoidal screw and are pressed against a grill (9) which surrounds the end of the screw, where the juice is extracted.
