Here's How Long Coffee Creamer Lasts Once You've Opened It

You've found your favorite flavor of coffee creamer, but can you be sure it's still good to drink days or even weeks after opening it? First, you shouldn't rely on the date printed on the label. Although we've come to think of those numbers as an expiration date, actually it's only a best assessment of when the quality of the product has changed. The general guideline from the USDA for liquid creamers is roughly two weeks once opened. If stored properly in the refrigerator, a sealed container should remain fresh for a couple of months.

To prolong the life of your creamer you could try freezing it in ice cube trays for individual servings, though be sure to seal these away in an airtight container once frozen to avoid picking up freezer funk. If you use containers made for the freezer, your creamer should last about six months.

It doesn't matter if your creamer is dairy or nondairy, as the USDA maintains that the shelf life remains the same. Just remember that the temperature of your fridge, exposure to light, and even the type of container used will affect the overall quality and shelf life of the product. Your best bet is to use an airtight vessel stashed closer to the back of the fridge, where temperature and light fluctuations are less likely.

There are three things that you can do if you're unsure about your dairy creamer. First, give it a sniff. If it smells sour or otherwise off, then it might be expired. Second, take a close look at the contents of the container — you might even wish to pour some into a clear glass for a better look. If you notice chunks, off-color or even mold, these are clear signs to pitch it. Finally, you might taste it (which is only advisable if you're still unsure). If it at all tastes weird, be safe and get rid of the stuff.

Mind you, all of this information is for liquid creamer bought in the refrigerated section. Those shelf-stable, individual cups of the sort you might find at your local diner are a different story. With these, always check the use-by date that should be printed on the package. These products generally have a year-long shelf life. As long as they're unopened, you typically have a month past that date to consume (though always use your senses and best judgment upon opening that package).

Powdered creamers, on the other hand, can remain on your pantry shelf for about two years as long as the temperatures and humidity levels in your storage area stay moderate. After opening it, keep powdered creamer in an airtight container to keep it from losing quality.
