Expiration & Storage Tips
When does whole milk expire?
If unopened, whole milk typically keeps in the refrigerator for about seven to ten days past the date printed on the package. However, once opened, it's usually good for approximately five to seven days, provided you keep it refrigerated at all times. In the case of frozen whole milk, it can last up to three months in the freezer, but for the best quality, it's wise to consume it within a month. Just remember, freezing may cause slight changes in texture and taste upon thawing.
How do you tell if whole milk is bad?
Whole milk that's gone bad typically develops a sharp sour odor that's pretty unmistakable once you've experienced it. The texture may also change, starting to clump or form chunks. If you notice either of these signs—give it a whiff or a quick look before tasting—you should discard the milk. Remember, it's always better to be safe than sorry with dairy products!
Tips for storing whole milk to extend shelf life
• Always keep your milk refrigerated—the back of the fridge is best since it’s the coldest part.
• Don’t leave your milk out on the counter for long periods. Return it to the fridge as soon as possible after using it.
• To freeze milk, ensure there's enough headspace for expansion in a airtight, freezer-safe container. Thaw it out in the fridge (not on the counter), and give it a good shake before using to redistribute any separated fats.
• Try not to store milk in the fridge door, as the temperature fluctuates more in this area which can affect its quality and lifespan.
