Improvements in a single serve point of consumption beverage dispensing valve is disclosed. The valve includes a fresh water input fitting, a carbonated water inlet fitting a vacuum pump that transfers concentrated from a flavor bullet and diffuses the concentrate with water an optionally carbonation to provide a consistent mixture. The flavor bullet manifold is self-cleaning to eliminate flavor cross-contamination. An initiation lever starts the mixing, diffusion and dispensing that is monitored and controlled with a micro water flow metering system that controls flow solenoids and dispensing of the mixed beverage.
