Abstract: A rotationally molded transparent back bar freezer unit having an insulating double wall. A housing receives an inner compartment 30 made of a thermally-conductive material. A recess contoured to match a shape of a fluid container is formed in the inner compartment 30 and defines a second volume. A cooling material, such as ice and salt added to a first volume within the inner compartment 30 cools the fluid container in the second volume through the flexible wall. An access door facilitates presentation, loading and extracting of the fluid container into and from the recess that forms the cooling compartment.
