Abstract

In some embodiments of a fluid dispensing system: (1) two or more mixing channels are fluidly connected to (a) a mixing chamber fluidly connected to a dispenser, (b) a particular two or more solvent reservoirs, and (c) a respective one or more ingredient reservoirs, wherein each of the ingredient reservoirs is configured to dispense into a respective one of the mixing channels; and (2) a controller is programmed to receive a request for a fluid mixture, and, in response control the system to: mix, in the mixing channels to form an intermediate fluid mixture, a respective predetermined amount of solvent from each of the particular solvent reservoirs and a respective predetermined amount of the ingredients from some of the ingredient reservoirs; flow, to the mixing chamber and then to the dispenser, the intermediate fluid mixture; and dispense the requested fluid mixture (including the intermediate fluid mixture) via the dispenser.
