An installation for the preparation of multicomponent liquid mixes in the production of alcoholic liquors includes a plurality of feed tanks, a dispensing pump unit for feeding respective ones of the liquid components, a plurality of suction pipings each of which communicates between a respective feed tank and a respective dispensing pump of the dispensing unit, a header for collecting the liquid components, a plurality of delivery pipings each of which communicates between a respective dispensing pump and the header and a receiving tank adapted to receive the mixed liquid components. A throttling mixer is arranged substantially at the outlet of the header means and includes normally closed membrane valves which are provided with respective membrane actuators having above-membrane chambers. The above-membrane chambers of the membrane actuators communicate with the suction pipings and a common delivery pipe which itself communicates between the outlet of the throttling mixer and the receiving tank.
