A dispensing nozzle includes an outer housing defining an interior and a nozzle outlet. A mixing nozzle insert is positioned within the nozzle housing. The insert has a central elongate core that includes a top end that is positioned adjacent inlets for water and juice concentrate, and a bottom end opposite there from adjacent the outlet of the nozzle. The insert includes a concentrate disk on its top end having a perimeter edge positioned closely adjacent an interior surface of the nozzle housing. This disk includes one or more flow holes extending there through. The insert also includes, below the concentrate disk, a plurality of mixing projections having alternating extensions integral with the central core and extending outward there from along the length thereof. The insert and the nozzle housing are designed so that the syrup concentrate is introduced above the concentrate disk and the water is introduced at a level just below the concentrate disk. In operation, when a pour is signaled, concentrate immediately flows through the concentrate disk holes to mix with the water there below. After the pour is stopped, the syrup concentrate is retained above the concentrate disk, as a lack of pressure prevents the concentrate from readily flowing through the orifices thereof. Prior to the following pour, there exists no syrup collected below the concentrate disk that would contribute to an initial pulse of darker concentrate.
