• a controlled gas system fluidly connected to the manifold;
• and
• an adaptor module releasably connected to the manifold and releasably coupled to the controlled gas system and the tap through the manifold, wherein the adaptor module is configured to be attached to the beverage container
• wherein the manifold includes a first surface configured to slidably receive a corresponding second surface on the adaptor module such that the first surface and the second surface are in contact when the adaptor module is fluidly coupled to the controlled gas system and the tap, and
• wherein the adaptor module is configured to be attached to the beverage container before being coupled to the controlled gas system and the tap and is configured to provide fluidic coupling from the beverage container to the controlled gas system, such that a beverage may be dispensed from the tap with the aid of positive gas pressure disposed on a beverage surface within the beverage container.
