The hot must which drains into the ring-shaped tank 2 is recycled to the steeping ring 31 through a pump 6 via an exchanger 7. Blades 23, 24, 25 are driven in rotation around the axis zz1 of the unit and sweep the bottom of the steeping and draining rings and of a trough 17 for draining the cold grapes.
