Abstract: The invention described herein is a beverage cooler, equipped with an external valve or spigot in fluid communication with an internal bag or bladder, the bladder containing the beverage to be dispensed. The bag is typically connected to the external spigot by a length of hose or other conduit. The bag or bladder includes a fitting, and the hose includes a complimentary fitting that allows the bag to be attached to the conduit for dispensing of the beverage, and subsequent removal from the conduit or hose when the bladder is empty. Once the bag is connected, ice can be placed in the cooler to keep the beverage cold.
