A tapping stem is used with a liquid dispenser for dispensing liquid from a disposable liquid container. The stem has a generally elongated body including a piercing end, a discharge end and a peripheral flange affixed to the discharge end. The piercing end has a generally cylindrical portion and an adjacent tapered portion terminating in a sharp tip for piercing the wall of the container. The stem body includes an intake passage and a discharge passage aligned along generally separate, parallel axes and dimensioned to intersect each other. The intake passage forms a channel in the piercing end, which channel extends substantially to the tip.
