A pressure regulating system 12 for a beverage container 2, comprising a first compartment 11 for containing a pressurized gas, in fluid communication with a surrounding space through at least a gas valve 13 for opening and closing a passage between the first compartment and surrounding space, wherein a gas valve control system is provided, comprising a deformable and/or movable wall or wall part 17, wherein said deformable and/or movable wall part is operably in contact with said gas valve for opening and/or closing said gas valve 13, wherein a second compartment 15 is provided at a side of the said deformable and/or movable wall part 17, said movable and/or deformable wall part 17 forming a wall of said second compartment 15, wherein the second compartment 15 forms a pressure regulating space and comprises a wall part formed by or comprising at least a gas permeable, liquid tight permeable wall part 24.

A pressure control device for controlling a pressure in a beverage container comprises a gas filled pressure control chamber enclosed by a wall of the pressure control device. The wall has an inner surface facing the chamber and an outer surface facing away from the chamber, the inner surface and outer surface defining a thickness of he wall. A scavenger material is provided in the pressure control device for capturing gas that enters, during use, into the pressure control chamber. The scavenger material is distributed over the wall thickness with a predetermined concentration from the inner surface towards the outer surface of the wall such that a rate of gas capture by the scavenger material changes over time.

Ingredient dispensing systems and methods are disclosed. A disclosed system includes an ingredient reservoir and an electromechanical valve configured so that, when the electromechanical valve is activated, an ingredient is dispensed from the ingredient reservoir. The disclosed system also includes a current sensor configured to measure a current draw of the electromechanical valve. The disclosed system also includes a controller programmed to sample the current draw from the current sensor and to detect a dispense error of the electromechanical valve based on the sampled current draw.

In some embodiments of a fluid dispensing system: (1) two or more mixing channels are fluidly connected to (a) a mixing chamber fluidly connected to a dispenser, (b) a particular two or more solvent reservoirs, and (c) a respective one or more ingredient reservoirs, wherein each of the ingredient reservoirs is configured to dispense into a respective one of the mixing channels; and (2) a controller is programmed to receive a request for a fluid mixture, and, in response control the system to: mix, in the mixing channels to form an intermediate fluid mixture, a respective predetermined amount of solvent from each of the particular solvent reservoirs and a respective predetermined amount of the ingredients from some of the ingredient reservoirs; flow, to the mixing chamber and then to the dispenser, the intermediate fluid mixture; and dispense the requested fluid mixture (including the intermediate fluid mixture) via the dispenser.
