A tap adapter (38) suitable for use in dispensing an alcohol beverage from a keg (12) which tap adapter has a hollow arm (120) adapted for mounting to a valve assembly (40) in fluid flow communication with a beverage dispensing valve (54) in the valve assembly. The arm may contain a dispensing tube (128). A first end portion (122) of the arm is adapted to releasably connect to the beverage dispensing valve to open the valve and has a tap (14) permitting beverage to flow through the hollow arm and out the tap. An airline passageway (50) is adapted to be connected to a second valve (56) in sealed fluid flow communication therewith passing through the valve assembly or keg. A source of air (10) is connected to the airline passageway for supplying pressurized air to the second valve and into the keg. A relief valve (190) is provided which can be opened to allow air to pass into the discharge tube upstream of the discharge end portion (124) whereby the beverage in the discharge tube downstream of the relief valve freely flows out of the discharge end portion.
