A must clarification device is provided comprising a vat into which the must is introduced in either a continuous flow or in batches. Located within a circular chamber in the vat is a turbine rotatable by external means. The must is introduced into the chamber by a centrally located pipe. An air pipe is located concentrically within the must pipe. The pipes are arranged to create a venturi effect to suck the air into the chamber. The turbine mixes the air and must and expells it from the chamber so that the air bubbles cause the impurities to rise to the surface where they are removed.
