Gochujang, a traditional Korean chili paste, can last for up to two years if stored in the refrigerator after purchase. However, it is important to keep an eye on its expiration date as, much like other condiments, gochujang should be disposed of after its 'best by' date has passed. Contrary to popular belief, it is not safe to use past this date even if the product looks and smells okay. This is because food products can contain bacteria that will cause sickness and even lead to more serious health problems. Therefore, when it comes to gochujang it is always best to err on the side of caution and discard any tubs that are beyond their use-by-date.
