Abstract

A beverage dispenser and process of dispensing a beverage may include pumping a micro-ingredient from a micro-ingredient container via a fluid path toward a nozzle to dispense a beverage inclusive of the micro-ingredient. The micro-ingredient may be reverse pumped via the fluid path back to the micro-ingredient container to cause an air bubble in the fluid path to be pushed into the micro-ingredient container.
