Who thinks about storing Milk? There are a few simple things that you should keep in mind to help keep your milk fresh.
Do you get the plastic jug or the carton? When you buy milk, you should get it in the carton. The carton helps insulate the milk and keep it at a more even temperature. This will help it from spoiling as quickly.
Your refrigerator should be kept at 40 degrees, and the milk should be stored on a shelf inside the refrigerator and not on the door. The door has too drastic of temperature changes every time the door is opened.
No matter what the expiration date on the carton, you should dispose of milk that has been opened for more than one week.
If you need to store it for longer, freeze it. You can store milk frozen for up to 3 months.
