The present disclosure relates a method for extending a shelf life of at least one packaged composition within a consumer accessible cooling device adapted to cool the at least one packaged composition to a composition temperature which is a first supercooled temperature. The method comprises storing the at least one packaged composition within the consumer accessible cooling device at a first supercooled temperature and increasing the composition temperature to a second temperature during a time period in which the at least one packaged composition will not be removed from the consumer accessible cooling device by a consumer. The at least one packaged composition comprises a pressurized composition in a liquid phase within a sealed container. The pressurized composition comprises a solvent and a solute substantially dissolved in the solvent and is at a pressure greater than atmospheric pressure. The pressurized composition remains liquid while the at least one packaged composition is maintained at the first supercooled temperature in the consumer accessible cooling device and at least partially freezes in response to the sealed container being removed from the consumer accessible cooling device and opened or agitated by the consumer.
