Do tea bags expire? The short answer is yes and no. Most tea doesn’t truly expire but - just like coffee - the freshness of the tea will start to deteriorate beyond the expiration date. While some pure blend teas can be consumed past their expiration date (though it’s not recommended), any blend that contains added perishable ingredients like fruit should be more carefully examined after the expiration date before drinking.


Picture this: you're steeping along and start sipping on the comforting cup of tea you just made, only to realize the box says it expired months ago! If you're worried that drinking expired tea after the best by date will make you instantly ill, don't worry - only in extreme cases will old tea make you sick. However, it's likely that any tea consumed beyond a recommended best by date will start to taste bad and bitter, a natural sign that your tea has gone bad. Also, you can tell if tea is really expired and unsafe to drink if it's been exposed to extreme humidity or liquid and has developed mold, which can make you sick or upset your stomach.


When stored properly, tea can last for up to 1-2 years. After that, most teas start to lose its original flavor and nutritional benefits. The less fermented and more broken tea leaves are, the faster they expire. As a result, tea bags can expire faster than loose leaf tea because they usually contain broken leaves and tea dust that lead to the deterioration of the tea’s flavor. However, the flavor of individually wrapped tea bags will usually last longer than open tea sachets when stored properly. When kept in an airtight and dark container, loose leaf tea will last longer and retain its flavor even more than tea bags.

Certain types of tea will also expire faster than others. The most oxidized teas will stay fresh the longest, which is why black tea leaves last the longest when stored properly. Green tea expires faster than black tea because it’s less oxidized and similar to the more minimally processed teas like white tea and oolong tea. Herbal tea can expire when there are added ingredients like berries and flavoring that can get old. An exception is pu-erh, a fermented tea that will only get better with age. Most well kept pu-erhs are aged for 2-10 years, but some can be up to 50 years old!


We know now that most teas don’t expire, the flavors will just degrade over time. However, some teas can go bad if they’re stored improperly and exposed to humidity, they absorb different flavors, or they get wet and develop mold. You can tell if your tea has gone bad by the smell, taste, and feel of the tea.

Don’t drink your tea if it smells musty because it has become too moist. Or, if it has no scent at all and the flavor of your tea is dull then it is also too far gone.

It might be hard to notice mold on tea leaves at first if you’re not looking for them, but if you’re worried about your tea then start by checking around the tea package, inside tea bags, and on the bottom of tea tins or tea boxes for loose leaf tea. If you think there could be mold, take out a scoop of your loose tea to inspect them on a plate or napkin.

Finally, you can check the texture of your tea leaves to tell if they’re still fresh or not. Fresh tea leaves will feel smooth and strong, while old tea leaves tend to crumble and break up in your hand.


The key to keep your tea from expiring too soon, and maybe even to extending the freshest flavor of your tea beyond the expiration date, is proper storage. Loose leaf tea, tea sachets, and even individually wrapped tea bags should always be stored in airtight containers like a tea tin, jar, box, or sealable bag. This will protect your tea from getting wet (until you want to steep it!) so it doesn’t develop mold. These should be placed in a dark, cool, and dry area like a cabinet or pantry shelf away from other strong scents like spices.

You should never store your tea bags or loose leaf tea in the fridge or freezer. Tea easily absorbs other scents and is sensitive to moisture. When stored in the fridge or freezer, tea is exposed to a humid environment and other flavors that mingle with the tea leaves and make them go bad prematurely. However, the only exception is if you're cold brewing tea or storing iced tea! Cold brewed tea and iced tea can last 2-5 days in the fridge when stored in an airtight container like a jar or pitcher.



Don't worry if you think your impressive collection of tea is about to expire, it doesn't have to go to waste! Here are a few ways to use up some of your extra tea before it goes bad.

  • Throw a tea party. Bake up a few batches of delicious tea cookies or scones, and invite your friends and family (virtually or in person!) for a classic afternoon tea party.
  • Plan a mug swap. Tell everyone you invite to bring a mug or teacup and once they arrive let the exchanging begin! Once everyone has a new mug in hand, brew up a few pots of tea so your guests can try them out. You can even make tea goodie bags to send them home with a few new teas to try.
  • Send tea care packages, because who doesn't love snail mail and tea!
  • Have a crafting day! Drink tea and make your own tea infused candles.
  • Embrace summer with all things tea. Learn how to start making tea popsicles and how to turn any tea into a smoothie!
