A nozzle 20 has a fluid flow passage 26 which defines a fluid flow path from an inlet 5 end of said passage towards an outlet end of said passage. A restrictor 29a is movable under the control of an actuation system 27 relative to the passage to vary the minimum cross-sectional area of the fluid flow path through the passage. The restrictor 29 is moved to project into the passage to provide a restricted opening in the passage or removed from the passage to allow an unrestricted flow through the 10 passage. The nozzle 20 is particularly suitable for use in a beverage preparation machine to generate microfoam in a beverage. When the restrictor 29 is retracted from the passage 29, the passage and the restrictor can be cleaned by flushing the nozzle. The restrictor 29 may be a pin-like member aligned with the passage and moveable parallel to the axis of the passage.

A pressurized beverage dispensing device that includes a vessel, a gas reservoir, a pressure regulation device, a primary filter, and a tap assembly. The gas reservoir is configured to supply pressurized gas within the vessel. The pressure regulation device is configured to maintain a pressure within the vessel that is above ambient pressure. The primary filter is configured to fit inside the vessel and to be removable from the vessel. The tap assembly includes a tap valve, a restrictor, and a flow straightener. The tap valve is configured to control dispensing through an outlet path. The restrictor is within the outlet path of the tap assembly and is configured to accelerate a flow of beverage to a turbulent flow. The flow straightener is within the outlet path of the tap assembly, downstream of the restrictor, and is configured to recombine, slow, and straighten the flow of beverage.

A beverage dispenser is for dispensing a consumable beverage. A processing line having a fluid path with an input end is fluidly connectable to a source container of liquid for receiving liquid from the container via a driving force, and for processing the liquid into the consumable beverage to be dispensed. A Venturi injector is provided along a fluid segment of the fluid path of the processing line, the Venturi injector being configured for selectively and adjustably injecting gas bubbles into the consumable beverage to alter at least one resulting parameter of the consumable beverage to be dispensed. The beverage dispenser also includes a tap fluidly connectable to an output end of the fluid path of the processing line for receiving the consumable beverage with at least one resulting parameter having been altered, and for selectively dispensing the consumable beverage via an activation of the tap.

Certain aspects relate to systems and techniques for smart draft beer taps that can dynamically vary flow rate and control the amount of dispensed head based on one or more of sensed parameters of the beer, the draft beer environment, characteristics of the beer, and on brewery specified pouring standards. The disclosed systems provide networked data communication relating to bar draft beer pouring conditions.

A dispense tap with integral gas/liquid infusion for dispensing a beverage at a given dispensing point inside a restaurant, a coffee shop, a bar, or a convenience store, features a mixing chamber having at least one gas input port configured to receive at least one incoming gas stream; at least one liquid input port configured to receive at least one incoming liquid or concentrate stream; and an infuser configured to mix the at least one incoming gas stream and the at least one incoming liquid or concentrate stream at the given dispensing point within the dispensing tap, and provide a mixing chamber stream containing a gas infused liquid mixture of the at least one incoming gas stream and the at least one incoming liquid or concentrate stream for dispensing as a beverage. The degree of absorption of the at least one incoming gas stream and the at least one incoming liquid or concentrate stream in the gas infused liquid mixture depends at least in part on sensed gas, liquid or concentrate pressure characteristics of one or more of the at least one incoming gas stream received by the infuser, the at least one incoming liquid or concentrate stream received by the infuser, or the gas infused liquid mixture provided from the infuser.
