So you’ve found some tea in the back of your pantry, probably past its expiration date, and you’re wondering if it’s safe. Can tea really go bad? Or are those dates just there to make you buy more?
Here’s the honest answer: tea doesn’t “expire” like milk or meat, but it can still get nasty if not stored right. Mold, stale flavors, and lost benefits are all things that can come with expired bags. But just because the flavor is weaker doesn’t mean it’ll make you sick unless something’s grown in it.
The crucial part is that it is mostly safe, but there are reasons to be cautious.
In this breakdown, we’re covering exactly what you need to know about drinking expired tea.

So, Can It Actually Make You Sick?
Consuming it expired is usually safe, but there are risks if it has been stored improperly or contains signs of mold or bacterial growth. While tea itself doesn’t “go bad” like fresh foods, exposure to moisture, air, and heat can turn it into a breeding ground for harmful bacteria or mold.
Expired tea can cause illness if it becomes contaminated, particularly if the tea shows signs of spoilage like mold or an unpleasant odor. The primary risks of drinking expired tea include gastrointestinal symptoms like nausea, vomiting, and diarrhea due to the potential growth of harmful bacteria and mold.
Symptoms can range from mild to severe and may include abdominal pain and, in rare cases, fever and dehydration. While expired bags that are properly stored might lose flavor without becoming harmful, it’s essential to avoid those that look or smells off to prevent possible foodborne illnesses
Risks of Drinking Expired Tea
- Bacterial Contamination: Expired bags, especially in humid environments, can harbor bacteria like Salmonella or E. coli. Drinking contaminated beverage can lead to food poisoning with symptoms including abdominal pain, dehydration, and fever.
- Mold Growth: Mold is more likely in bags stored without proper airtight sealing. Mold exposure can cause respiratory or digestive issues. Experts recommend that you avoid bags with visible mold or an unusual odor to prevent any adverse reactions.
- Loss of Nutritional Value: The antioxidants and beneficial compounds degrade over time. Although this doesn’t pose an immediate health risk, it reduces the health benefits, which can affect its efficacy as a wellness beverage.
Dr. Ketan Desai, Chief Educator at VAHDAM India, notes that tea stored in cool, dry places remains safe longer, but it’s essential to inspect leaves regularly, especially if they’ve been stored for extended periods.
Proper Storage to Reduce Health Risks
Tea should be stored in a cool, dry place, in airtight containers that block light and moisture. Avoid storing it near heat sources or in humid locations like the refrigerator. These conditions help prolong the tea’s shelf life and reduce the likelihood of contamination.
When to Discard Expired Bags?
Look for these indicators that it’s time to toss out:
- Visible mold or discoloration
- An unpleasant or musty odor
- Stale, bitter, or “off” taste
How Expired is “Too Expired”?
Leaves don’t truly expire in the way that fresh foods do, but the quality and safety change as they age. Typically, packaged bags have “best by” dates that suggest when it will be at peak quality, which usually ranges from 18 to 24 months for green tea and up to 3 years for black tea if stored properly.
- Green and white are more delicate, with freshness lasting 6 to 12 months, as they lose flavor and nutrients faster due to minimal oxidation.
- Black and dark are heartier, staying fresh for up to two years or longer when stored in airtight containers, thanks to their higher oxidation levels.
- Herbal and floral generally have shorter shelf lives (around 6 to 12 months) as their ingredients degrade quicker.
When to Discard Old Tea Bags?
If there are visible signs of mold, a musty or acidic smell, or discoloration, it is best to throw it out. Moisture can lead to bacteria or mold that may cause digestive issues. Even if there’s no visible mold, a stale or “off” smell warns that the tea’s quality has declined, making it unsuitable for use.
Properly stored leaves can often remain safe beyond its labeled “best by” date, although fresher tea will always provide a more enjoyable and potent brew.

Creative Ways to Give Expired Tea New Life
When tea is past its drinkable days, don’t rush to throw it out. Here’s how to turn those old tea bags and leaves into something useful and creative around the house.
1. Boost for Plants
Expired tea leaves can give your plants an extra lift. Sprinkle loose tea or bag contents around your garden or indoor pots. The natural nitrogen and minerals in tea enrich the soil, making it a great organic fertilizer.
2. Natural Odor Absorber
The leaves work well to absorb odors. Dry out old bags and place them in shoes, gym bags, or the fridge to neutralize bad smells.
3. Eye Compress for Puffiness
Expired bags can help with puffy eyes. Just wet them with cold water, chill them, and place them over closed eyes for a refreshing fix.
According to an article on Healthline by Emily Cronkleton, using tea bags as a cold or warm compress on the eyes can offer relief for several common eye issues. Cold bags help reduce puffiness, dark circles, and even irritation from the pink eye by constricting blood vessels and calming inflammation. Warm bags can be beneficial for conditions like blepharitis, where applying gentle heat loosens flakes from the eyelids and helps prevent clogged oil glands, easing symptoms effectively. Using black or green for these compresses also provides the added benefit of antioxidants that soothe the skin around the eyes
4. Gentle Wood Polish
Use brewed, cooled black tea as a gentle polish for wooden furniture. Simply dip a soft cloth in the tea and wipe down wood surfaces. It helps bring out a natural shine and cleans dirt or dust.
5. DIY Hair Rinse
Tea, especially black, can be used as a final rinse for your hair, adding shine and even enhancing darker tones. Brew a strong batch, let it cool, then use it after your regular shampoo routine. It’s a simple, natural hair boost.
6. Compost Ingredient
Add leaves to your compost pile. They break down easily and contribute nitrogen, enriching the compost. Just remember to remove any non-biodegradable elements, like staples in tea bags, before adding them in.
7. Bath Soak
Old herbal teas, especially those with chamomile or lavender, can be added to a warm bath for a relaxing soak. Drop a few tea bags in your bath, and they’ll add a gentle, natural aroma to the water.
FAQs
Can Expired Tea Attract Pests?
Yes, if expired tea is stored in a humid environment, it can attract pests like pantry moths or weevils. Keeping tea in airtight containers can prevent this issue.
Are There Any Teas That Should Not Be Used After Expiration?
Delicate teas, like matcha and some floral or herbal blends, may degrade faster and lose their effectiveness entirely after expiration. In addition, teas with added flavors, oils, or fruits can spoil quicker, and they may not be suitable for any use if they have turned rancid.
Can I Use Expired Tea to Dye Fabric?
Yes, black tea especially can be used to dye fabrics naturally, even if expired. The natural tannins in black tea give fabrics a subtle earthy tone, but keep in mind the results will be softer than with fresh tea.
Is There a Limit to How Long Expired Tea is Useful for Repurposing?
Most teas are useful for non-drinking purposes within two to three years past expiration if they show no signs of mold, odor, or other contamination. After this period, the tea’s beneficial compounds may degrade significantly, reducing its effectiveness even for repurposing.
Final Words
Expired tea can still serve a purpose beyond the cup. As long as there’s no mold, off-smell, or discoloration, properly stored tea often stays safe beyond its “best by” date, though fresher tea will always deliver better taste and benefits.
For those bags past their peak, don’t be quick to toss them. There are plenty of creative ways to use tea around the house.
