The short answer is yes. Tea bags can and will expire. You will likely never look at the expiration date on a tea box and immediately throw it out because it’s gone bad and is no longer drinkable. There are a few other things to consider before making that decision. Don’t throw out that box quite yet.

Tea bags can stay fresh for years if they are stored properly. But that doesn’t mean that they will taste good forever. A tea bag may not get moldy, but it will still lose taste and value as it gets older.

The tea will get drier and lose its natural oils. Those natural oils are what give the tea that amazing flavor. It’s pretty easy to spot a cup of tea made with a fresh tea bag vs. an old one. That will be up to personal preference. If you are ok with drinking a less flavorful cup of tea, you’re likely to fare just fine with keeping your tea bags stored for a few months.

Most tea bag boxes will have a “best by” date. This date means that the tea is best consumed prior to this particular date. Brewed tea might not taste as good if you wait to drink it until after the “best by” date. All tea will taste best prior to the “best by” date. It just might taste a little different if you wait until after that date.

The “best by” date on most tea boxes is one to two years after the production date. This does not mean that the tea is expired and unsafe to drink past this point. This is a date, set by the manufacturer, that is a recommendation.

They recommend that you drink the tea before this date for the best tasting product. Drinking the tea bag before this date is going to guarantee exceptional flavor. The box might even state the amount of time that the tea bags are good after the expiration or “best by” date.

The tea bags will need to be stored properly in order to even live up to it’s “best by” date. It is important to keep tea bags in a sealed container. This is especially important if they are not individually wrapped tea bags. You will want to take proper storage steps with the tea bags as soon as it’s opened. Even if you don’t plan on keeping all of the tea for long term store, it’s important to store the bags correctly.

How Do You Know When Tea Goes Bad?

know when tea goes bad

Yes, tea bags can still go bad. Tea bags can still become unusable even when they are stored properly. Whether they are in or out of their original packaging, there is a chance that they might go bad. Most of the packaging provided by the manufacturers will not suffice for proper storage. Sometimes tea bags are stored in a simple paper bag and that will not suit for long term storage.

You can tell if a tea bag has gone bad by looking for a few things.

Inspect the box carefully if you haven’t opened the box yet and it’s past the “best by” date. Most tea bags will come sealed in plastic, but some may not. Check the box for any holes or rips. Sometimes little critters might want to chew their way through a box of delicious smelling tea. That’s not a good thing. Be sure to dispose of the box immediately if you think a small critter has gotten into the box.

Also, make sure that the box has not gotten wet at all. If the box seems damp, it should be thrown out. If a box has gotten wet and has not been opened for a long time, it might have developed mold. Check both the outside and inside of the box. Smell it, too. The box should not smell like mildew.

If the box seems ok, you can open it and start to inspect the tea bag. You want to be sure that the tea bag has not been broken or compromised in any way. If the tea bag has a hole in it, it is no longer usable. Throw it away immediately and find a new tea bag.

The tea bag should also be free of any bugs on the inside or outside. Sometimes very small bugs can get into the bags even if there are not any holes. Thoroughly check to be sure that there is nothing foreign in the tea bags. If you find any bugs, it’s safe to say you should discard that tea bag and any other tea bag it was stored with.

Tea bags should smell like tea bags. It should be easy to tell if your tea bag smells different than the type that you originally purchased. If for some reason the tea bag smells tangy or like mold, it should be thrown out right away. Again, if this is the case, it’s best to throw out all other tea bags that were stored with the smelly tea bag.

There should be no mold on the tea bag or inside of it. This might be easier to spot on some tea bags over others. Some bags are very translucent, and you will be able to see if there is any mold or mildew on the tea bag. You can hold the tea bag up to a light or a bright window if you are having trouble seeing through the bag.

Fortunately, tea is inexpensive and can be replaced easily. If for some reason you do find something wrong with your stored bags of tea, you shouldn’t worry. Simply find another tea that is safe to drink.

The “best by” date is not the date that you need to throw the tea bags away. Most teas are going to be just fine long after the “best by” date.

Can You Drink Expired Tea Bags?

Can You Drink Expired Tea Bags

It is usually perfectly fine to drink a tea bag past its expiration or “best by” date. It’s crucial that you do check the tea bags to make sure that they are still safe to use. The tips noted previous are the best ways to be sure that the tea bags are safe to use.

There are a few things you might notice if you are drinking expired tea. The tea bags might not have as much flavor as they originally did. The tea bags are also going to be much drier than when you originally purchased them. This causes the loss of extra flavor.

There are a few teas that might change flavor quicker than others if kept for too long. Green and white teas, especially those that are flavored, are going to lose their flavor faster. The natural flavorings and oils that are added to the tea to enhance the taste will cause them to taste different after time. For example, a peach green tea bag is not going to stay as fresh as a standard green tea bag. Some of the more exotic and interesting flavors are also going to lose their flavor quicker.

Teas that are less expensive are going to lose flavor faster as well. You’ll notice these as more of the gimmicky flavors like pumpkin spice tea or berry-flavored teas. The flavors that are being used to enhance these teas are not usually natural parts of the tea. The shelf life of the additional flavors isn’t expected to be very long either. Be mindful of that when purchasing the next unique tea box, you come across. That unique box of tea is not going to last as long as some of the classic flavors, like black or green tea.

Black teas are generally unaltered and will stay consistent as time goes on. You can rely on black tea to stay flavorful for years. It’s usually in its natural state with no other additional flavors. This makes it one of the best teas to keep on hand for long term storage.

Drinking expired tea is perfectly fine if you understand the flavor might have altered a bit. Drinking tea past its prime date is safe as long as you are ok with drinking a tea that doesn’t have its original, robust flavor.

Can Old Tea Make You Sick

It’s very true that old tea bags could make you sick. Even when stored properly, it’s important to check tea bags before brewing. Following a few precautions while you’re brewing can help you avoid getting sick as well.

  • Water needs to be boiling and at least 175F/80C prior to brewing. Once the tea is brewing, be sure to let it sit for at least five minutes. This is going to kill any hidden, harmful bacteria.
  • It’s best to consume expired tea right away. If you do not plan on drinking it immediately, store it in the refrigerator.
  • Consume the tea within 24-48 hours if you opt to keep it in the refrigerator.
  • Countertop brewing and sun brewing are not recommended with expired teas. The water is not guaranteed to be hot enough to kill any potentially harmful bacteria.

Again, always check to be sure that the tea bags are safe prior to brewing them. If you did end up using a tea bag that had mold or bugs, and you weren’t able to brew it at a high enough temperature, there is a chance you could get sick. There is the potential that your tea bag could be carrying a food-borne disease, and nobody wants that.

It’s always safer to check the tea and discard it you question it at all. Tea is relatively inexpensive and easy to replace. It is not worth the risk of brewing a questionable tea bag.
