The invention relates to a berry or grape harvesting vehicle and a method for harvesting espalier fruit, especially berries or grapes of vines, and for further treatment of the espalier fruit, especially berries or grapes, to form a must on the harvesting vehicle. Said vehicle comprises a chassis (2) which is embodied in such a way as to overlap a row of plants to be reaped in a U-shaped recess, wheels (3) which are arranged on the chassis (2) on both sides of the U-shaped recess (9), a device for separating the espalier fruit from the vines, and preferably a stemming device for separating the berries from the stems, or the like. The invention is characterised in that a helical conveyor centrifuge, especially a solid bowl helical conveyor centrifuge (4) for further treating the mash, is arranged directly in the harvesting vehicle (1).
