Abstract: The present invention provides an automatic mixing and dispensing device that includes a plurality of storage reservoirs for various liquids interposed between a source of pressurized gas and a mixing and dispensing unit. The device further includes a final receiving area into which the liquids can be dispensed. The invention also provides a method for storing and delivering fluids to a centralized mixing and dispensing unit, which can include dispensing a mixed beverage to a final container, such as a cup. The method includes applying pressure to a reservoir tank holding a desired liquid, thus forcing the liquid from the tank into the mixing and dispensing unit. The amount of time that the pressure is applied to the reservoir tank correlates to a specific amount of volume delivered. The method can be accomplished using a computer.
