A portable beverage dispenser system is housed within a rigid back pack transported on the back of a vendor. A beverage dispensing container, dispensing hose, and a pressurized gas container is housed within the back pack. The beverage dispensing container has a rigid wall surrounded by a flexible thermally insulating and cushioning jacket and an access opening at the top end of the dispensing container receives a removable flexible liner. A releasably locked closure lid is removably mounted within the access opening and has a gas fill valve and liquid fill and dispensing valve thereon with passages extending through the closure. The flexible liner is inserted into and withdrawn from the dispensing container in a collapsed condition and substantially conforms to the shape of the interior of the container in an installed liquid filled condition. The liner has an open end releasably engaged on the lid closure and forms a fluid pressure sealed envelope for containing the liquid beverage and the pressurized gas. The pressurized gas container is connected to the gas fill valve to maintain pressurization of the liquid in the dispensing container, and the dispensing hose is connected at one end to the liquid fill and dispensing valve and has a manually operable dispensing valve at the other end for dispensing the pressurized liquid.
