Method and device for dispensing from liquid concentrates beverages having multi-layer visual appearance

摘要

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.
