Hartley's clarifies jam storage guidelines recommending fridge over cupboard

Hartley’s, a British jam brand, has clarified that opened jam should be stored in the fridge. This recommendation comes as homes are warmer, which can lead to quicker spoilage when jam is kept in a cupboard. The brand states that properly refrigerated jam can last at least six weeks after opening. For homemade jams, they should be stored in an airtight container in the fridge and consumed within 72 hours. While jam is often found on supermarket shelves due to its airtight seal, refrigeration after opening is essential to prevent spoilage and maintain quality.
