Store in a cool dry place and refrigerate after opening. Proper fridge storage: Store perishables (basically anything without vinegar or spice) in the center of the fridge/main portion and NOT the door. The main portion of the fridge is a consistent temperature, which is the goal. The door changes temperature degrees, sometimes drastically, depending on how often the fridge is opened, how long it stays open, etc. If not using immediately, store in a cool, dry place for up to a year for maximum freshness unopened. The shelf life for marmalades is about 2 years.
