Methods and systems for delivering foamed beverages from liquid concentrates through a dispenser machine

A method and system to deliver foamed beverages from liquid concentrate(s) through a dispenser machine is disclosed. In an embodiment, the method and system for improving foam quality by generating foam with the desired texture, stability and bubble size distribution comprises use of a low viscous liquid(s) to generate a primary foam, which is then stabilized by mixing it with liquid(s) of higher viscosity. To create high quality foam, different dosing protocols including two approaches such as delivery of foaming liquid concentrates at different concentration, or getting different concentration by varying water dosing times and/or flow rates were used. Positive results were found for the dispensing systems using milk and other liquid concentrates at specific dispensing conditions (flow rates and times).
