The invention relates to a method for dispensing a beverage with the visual appearance of multi-layers obtained from dilution of concentrates in proper dilution ratios. A first liquid layer is first delivered with a controlled density. A second liquid layer is diluted to a density that is lower than the density of the first liquid layer so that the first and second layers form a stable layered arrangement with the second liquid layer of lower density remaining spatially above the first liquid layer to provide a visually distinct layer as compared to the first liquid layer in the container. The invention also relates to a dispensing device and to a machine readable program enabling the device to deliver the multi-layer appearance beverage according to the method of the invention.

What is claimed is: 1. A method for dispensing a beverage with two or more superimposed liquid layers in a container, which comprises: providing at least one source of first liquid concentrate and at least one source of second liquid concentrate; pumping a metered amount of the first liquid concentrate from the source and delivering it into a containter to provide a first liquid layer therein; pumping a metered amount of the second liquid concentrate from the source, mixing it with a metered amount of water to form a second, diluted liquid layer from the second concentrate, and delivering the diluted second concentrate into the container and first liquid layer to form a second liquid layer; wherein the second liquid layer is diluted to a density that is lower than that of the first liquid layer so that the first and second layers form a stable layered arrangement in the container with the second, diluted liquid layer of lower density remaining spatially above the first liquid layer to provide a beverage having a visually distinct upper layer upon a lower layer in the container. 2. The method according to claim 1, wherein the first liquid layer is obtained by mixing the metered amount of first liquid concentrate with a metered amount of water and wherein the density variation between the first and second liquid layers is set by controlling the concentrate-to-water dilution ratio of the first liquid layer with respect to the concentrate-to-water dilution ratio of the second liquid layer. 3. The method according to claim 2, wherein the density variation between the first and second liquid layers in the container is controlled to be equal to or higher than 0.1%. 4. The method according to claim 3, wherein the density variation between the first and second liquid layers in the container is controlled to be comprised between 0.1 and 40%. 5. The method according to claim 1, wherein the first and second liquid layers are delivered in a gentle manner without causing significant turbulence in the container. 6. The method according to claim 5, wherein the metered amounts of dilution water provide flow rates to dilute and mix respectively with the amounts of first and second concentrates are each set to not exceed 20 mL/s for a container size of between 50 and 500 ml. 7. The method according to claim 6, wherein the water flow rates are between 5 and 10 mL/s. 8. The method according to claim 5, wherein the dilution water to dilute and mix respectively with the amounts of first and second concentrates are each set to have a flow linear velocity that does not exceed 120 cm/s. 9. The method according to claim 8, wherein the flow linear velocity is between 30 and 100 cm/s. 10. The method according to claim 1, wherein a pause is provided between the pumping of the first concentrate and the pumping of the second concentrate. 11. The method according to claim 1, wherein during or after delivering the first liquid layer, a metered portion of concentrate is mixed with water and further whipped to deliver foam directly onto the first liquid layer so as to slow down the delivery of the second liquid layer to the container. 12. The method according to claim 2, wherein the concentrate and dilution water for the first and second liquid layers form concentrate-to-water dilution ratios that are adjusted relative to each other to provide a temperature difference between the first and second layers in the container of at least 5% with the second layer having a higher temperature than the first layer. 13. The method according to claim 1, wherein the first and second concentrates have different visual and taste attributes. 14. The method according to claim 1, wherein the first and second concentrates have a different intrinsic density and different initial solids contents. 15. The method according to claim 14, wherein the first liquid concentrate is a milk based concentrate having between 15 to 33 wt. % total solids and a specific gravity of between 1.01 to 1.15 g/mL. 16. The method according to claim 14, wherein the second liquid concentrate is a coffee based concentrate having between 45 to 60 wt. % total solids and a specific gravity between 1.05 to 1.28 g/mL. 17. The method according to claim 16, wherein the amount of milk concentrate to water is present at a ratio that does not exceed 1:3 and the amount of coffee concentrate to water is is present at a ratio that is equal to or higher than 1:5. 18. The method according to claim 1, which further comprises pumping a metered amount of a third liquid concentrate from a source, mixing the metered amount of liquid concentrate with water, and delivering a third diluted liquid layer into the container, wherein the density of the third layer is set lower than the density of the first layer but higher than the density of the second layer. 19. The method according to claim 18, wherein the mixing and delivery of the diluted third concentrate is controlled to at least partially overlap with the delivery of the diluted first and/or second concentrates. 20. The method according to claim 18, wherein the delivery of the third concentrate is controlled to follow the delivery of the first layer from the first concentrate but to precede the delivery of the diluted second concentrate. 21. The method according to claim 1, wherein the third concentrate is a liquid sweetener. 22. The method according to claim 1, wherein the at least first and second concentrates are selected from the group consisting of coffee, milk, cocoa, sugar, micronutrients, fruits, plant extracts and combinations thereof.
