We consider the averaging process on an infinite connected graph with bounded degree and independent, identically distributed starting values or initial opinions. Assuming that the law of the initial opinion of a vertex has a finite second moment, we show that the opinions of all vertices converge in L² to the first moment of the law of the initial opinions. A key tool in the proof is the Sharing a drink procedure introduced by Olle H\"aggstr\"om.
