The first and second liquids are supplied to a suction side or an inlet of the constant volume pump and the second liquid supplied to the pump is measured by a measuring device to adjust it to a predetermined amount so that the first and second liquids are mixed in the predetermined ratio. The apparatus is suitable for mixture of beverages and for this purpose includes evacuating the tank for the first liquid to eliminate oxygen contained in the first liquid.
