Unopened milk lasts differently based on its type. Pasteurized milk can last up to one week past the printed date if kept in the fridge. UHT (Ultra High Temperature) processed milk, which doesn’t need refrigeration until opened, can last for two to four weeks past the date if stored in a cool, dark pantry, and up to a month in the fridge after opening. Always sniff and taste test before use to ensure it's still good.
FAQs & Answers

- Can unopened milk be frozen to extend shelf life? Yes, milk can be frozen to extend its shelf life, but it may change texture when thawed and should be used promptly after thawing.
