Beverage Dispensing Assembly Comprising an Ingredient Container Receiving Means and a Gas Pressure Regulator and Method of Dispensing a Beverage with Such Assembly

A beverage dispensing assembly for preparing and dispensing a beverage has a source of pressurized base liquid containing dissolved CO2, N2 or N2O and a gas pressure of at least 0.5 bar overpressure at 2° C. A beverage unit with a liquid flow path has a liquid inlet at one end in fluid communication with the base liquid in the base liquid source and a beverage outlet at an opposite end. An ingredient container receiving means has an ingredient container installed so the contents are in fluid communication with the liquid flow path for mixing the contents with a base liquid in the liquid flow path. A gas pressure regulation unit has a pressure chamber in the liquid flow path downstream of the communication between the liquid flow path and the ingredient container contents. A gas ingredient inlet is in fluid communication with the pressure chamber.
