A beverage dispensing system includes a base to which a dispensing head is removably attached without additional fasteners. Beverage-forming liquids are supplied through a plurality of separate conduits in the base. Each base conduit has a normally closed valve that normally blocks fluid flow. The dispensing head has at least one passageway that receives liquid from an associated one of the base conduits. A projection associated with each dispensing head passageway opens the associated conduit valve to allow fluid flow from the base to the head. Dispensing valves in the dispensing head regulate the dispensing of the beverage. By selectively opening the dispensing valves, a plurality of beverages are formed from combinations of one or more liquids. A dispensing head includes an inlet opening and an outlet opening at each end of a passage extending through a body, the inlet opening having a smaller cross-sectional area than the outlet opening.
