A method for designing or producing a coffee container system includes the step of constructing a sample of a coffee container system, where the container system includes a main container, a lift-off top, and a seal mechanism for the opening between the lift-off top and the container. Thereafter, oxygen ingress into the container system is measured when the lift-off top is in place and the seal mechanism is in operation. A sealing effectiveness of the seal mechanism is then modified to achieve a desired oxygen ingress for the container system, so that container systems housing coffee and having the modified seal mechanism providing the desired oxygen ingress can be manufactured. In addition, a method for retarding oxygen ingress into coffee contained in a container system is provided by infusing the coffee with a high molecular weight gas compatible with the coffee during manufacture of the finished coffee container system.
