Draft beverage is cooled in a cooling water tank in a cooling unit under a drinks bar. It is then cooled in a thermoelectric cooler, and transferred to a font in pipe which is surrounded in a water jacket of cooling water from the tank. The water jacket is connected to a further water jacket for a tube of cooling water which is also supplied to the font for cooling a glass into which the beverage will be dispensed. The waterjacket keeps the beverage in the pipe cool, but above freezing point, when it is static prior to dispense.
