A bottle filling apparatus is provided in which a non-contact choke val ve is employed. The choke valve comprises a disc having an outer cylindrical wa ll which is received within a valve seat having an inner cylindrical wall. The cylindrical walls have a close tolerance fit, preventing flow therebetween b y molecular action and surface tension. Additionally, the bottom surface of th e seal and the top surface of the seat have similar tapers such that, with the seat below the seal in a normal dispensing operation, beverage flow is directed into th e bottle without turbulence and the resultant foaming action.
