A beverage dispense system has a dispense nozzle with inlet sections for connection to beverage supplies that merge into an outlet section sized to match the flows such that a unit volume of beverage can be dispensed more quickly. The inlet sections are provided with separate valves controlling the flow so that beverage can be dispensed through either one or both inlet sections. The nozzle is automatically drained on completion of a dispense by air admitted to the nozzle via a passageway.

I claim: 1. A dispense head comprising a plurality of inlets for connection to separate beverage supply lines, each said inlet communicating with a respective one of a plurality of dispense valves and through its respective dispense valve with an associated one of a plurality of inlet sections that merge into a common outlet section leading to a common dispense nozzle, and including means for operating the dispense valves to provide a flow of beverage therethrough and from the dispense nozzle, such that a lower flow rate of beverage is provided from said dispense nozzle at one or both of the start of dispense of beverage and the end of dispense of beverage from said dispense nozzle by selectively opening and closing said dispense valves such that at one or both of the start of dispense of beverage and the end of dispense of beverage from said dispense nozzle at least one, but less than all, of said dispense valves are closed. 2. A dispense head according to claim 1, wherein said dispense valves are on/off solenoid valves. 3. A dispense head according to claim 1, wherein said dispense valves are operable via a control unit in response to user actuation of a dispense. 4. A dispense head according to claim 1, wherein said outlet section has a cross-sectional area matching the combined cross-sectional areas of said inlet sections. 5. A dispense head according to claim 1, wherein said inlet sections are inclined relative to said outlet section and converge to merge smoothly into said outlet section avoiding sudden changes in the direction of flow. 6. A dispense head comprising a plurality of inlets for connection to separate beverage supply lines, each inlet communicating with a dispense valve opening to a common dispense nozzle having a lower beverage outlet, wherein means is provided for draining the dispense nozzle downstream of the dispense valve when the dispense valve is closed, and wherein the drain means comprises an airway for admitting air to the dispense nozzle upstream from the outlet at the end of the dispense to drain beverage from the dispense nozzle through the lower outlet, wherein the airway comprises a passageway controlled by a drain valve that is closed to prevent air being drawn into the nozzle during beverage dispense. 7. A dispense head according to claim 6 wherein, when the dispense valve is closed at the end of the dispense, the drain valve is opened allowing air to be drawn into the nozzle by the vacuum created by the flow of the beverage and allowing the nozzle to drain fully. 8. A dispense head comprising an inlet for connection to a beverage supply line, said inlet communicating with a dispense valve opening to a dispense nozzle having an outlet, and means for draining said dispense nozzle downstream from said dispense valve through said dispense nozzle outlet when said dispense valve is closed, said draining means including means for admitting air to said dispense nozzle downstream from said dispense valve and upstream from said outlet, wherein said means for admitting air comprises an air inlet to said dispense nozzle upstream from the said outlet for admitting air into said dispense nozzle to drain said dispense nozzle on completion of a dispense. 9. A dispense head comprising an inlet for connection to a beverage supply line, said inlet communicating with a dispense valve opening to a dispense nozzle, and means for draining said dispense nozzle downstream from said dispense valve when said dispense valve is closed, wherein said drain means comprises an inlet for admitting air to drain said dispense nozzle on completion of a dispense, wherein said inlet for admitting air comprises a passageway controlled by a drain valve that is closed to prevent air being drawn into said nozzle during beverage dispense, and wherein a short time delay is provided on completion of a dispense before opening said drain valve. 10. A dispense head comprising an inlet for connection to a beverage supply line, said inlet communicating with a dispense valve opening to a dispense nozzle having a lower beverage outlet, and means for draining said dispense nozzle downstream of said dispense valve when said dispense valve is closed, wherein said drain means comprises an inlet for admitting air to said dispense nozzle upstream from said outlet to drain said dispense nozzle through said lower beverage outlet on completion of a dispense, and wherein said inlet for admitting air comprises a passageway controlled by a drain valve that is closed to prevent air being drawn into said nozzle during beverage dispense.
