Methods and systems to deliver foamed beverages from liquid concentrate(s) through a dispenser machine are presented. 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).

The invention is claimed as follows: 1. A method for producing a foamed beverage, the method comprising: dosing at least one product component at a first concentration; dosing a diluent; combining the product component and diluent together to form a mixture; and mixing the mixture to form the foamed beverage, wherein the dosing of the product component and diluent is controlled so that the product component concentration in the diluent increases during at least one cycle of combining and mixing, wherein the product component concentration is increased by a step selected from the group consisting of increasing a rate of introduction of the product component during dosing of the product component, decreasing a rate of introduction of the diluent during dosing of the diluent, and combinations thereof. 2. The method of claim 1, wherein the mixing comprises whipping. 3. The method of claim 1, wherein the product component is a liquid and the concentration of the product component is increased by increasing a flow rate of the liquid relative to a flow rate of the diluent. 4. The method of claim 3, wherein the liquid flow rate increases during a preparation cycle and the diluent flow rate is selected from the group consisting of substantially constant, decreases and combinations thereof. 5. The method of claim 3, wherein the liquid flow rate increases stepwise. 6. The method of claim 3, wherein the liquid flow rate remains substantially constant and the diluent flow rate decreases. 7. The method of claim 3, wherein the liquid flow rate remains substantially constant and the diluent flow rate intermittently stops for at least 1 second. 8. The method of claim 3 comprising at least two separate steps lasting at least 2 seconds each. 9. The method of claim 3, wherein the liquid flow rate is adjusted by a controller and a pump. 10. The method of claim 1, wherein the product component is a powder and a concentration of component-to-diluent is increased by increasing a dosing speed of the powder. 11. The method of claim 10, wherein the dosing speed is increased stepwise. 12. The method of claim 10, comprising at least two separate steps lasting at least 2 seconds each. 13. The method of claim 10, wherein the powder is dosed by a device selected from the group consisting of a volumetric screw, auger and combinations thereof, wherein the device is driven by an electric motor having a speed controlled by a controller. 14. The method of claim 1, wherein a diluent flow rate can be controlled by a device selected from the group consisting of an active pressure valve, pump and combinations thereof. 15. The method of claim 1, wherein the product component comprises a foaming component selected from the group consisting of dairy creamers, milk concentrates, milk powders, whey proteins, non-dairy creamers, non-dairy fats, non-dairy oils, premixes having foaming agents and non-foaming components, emulsifiers and combinations thereof. 16. The method of claim 15, wherein the product component includes a non-foaming component selected from the group consisting of coffees, cocoas, sweeteners, preservatives, flavorings, colorings, nutritional ingredients and combinations thereof. 17. The method of claim 1, wherein the beverage is produced by mixing at least one additional product components from another source. 18. The method of claim 1, wherein the product component is maintained in a condition selected from the group consisting of chilled, shelf-stable and combinations thereof. 19. The method of claim 2, wherein the whipping is performed in a standard rotary whipping device in a range between about 10,000 to 15,000 r.p.m. 20. The method of claim 2, wherein the whipping is achieved by jets streams. 21. The method of claim 1, wherein the diluent is water. 22. A system for producing a foamed beverage, the system comprising: a first dispenser capable of dosing at least one product component at a first concentration; a second dispenser capable of dosing a diluent; and a whipper for mixing and whipping the product component and diluent together to form the foamed beverage, wherein the dosing of the product component and diluent is controlled by a controller so that the product component concentration in the diluent increases during at least one cycle of mixing and whipping, wherein the product component concentration is increased by a step selected from the group consisting of increasing a rate of introduction of the product component during dosing of the product component, decreasing a rate of introduction of the diluent during dosing of the diluent, and combinations thereof. 23. The system of claim 22, wherein the product component is a liquid and the concentration of the product component is increased by increasing a flow rate of the liquid relative to a flow rate of the diluent. 24. The system of claim 23, wherein the liquid flow rate increases during a preparation cycle and the diluent flow rate is selected from the group consisting of substantially constant, decreases and combinations thereof. 25. The system of claim 22, wherein the product component is a powder and a concentration of component-to-diluent is increased by increasing a dosing speed of the powder.
