Tea is a beloved beverage across the globe, enjoyed for its comforting warmth, health benefits, and endless flavours. While loose-leaf tea has its devotees, most people brew their tea with tea bags for convenience. But how much do you know about tea bag safety, shelf life, and the best ways to use—or even reuse—them? Let’s dive into the important facts you should know.
Are Tetley tea bags safe?
Yes, Tetley tea bags like these ones that we have are considered safe for consumption. They undergo strict quality checks to ensure they meet food safety standards. However, like many popular brands, questions have been raised about the materials used in tea bag production. This leads us to the next question many tea lovers are curious about.
Do Tetley tea bags have plastic in them?
Tetley’s traditional heat-sealed tea bags do contain a small amount of plastic—specifically polypropylene—used to seal the bag and keep it from falling apart in hot water. While the amount is minimal and approved for food contact, eco-conscious consumers may prefer plastic-free options, such as Tetley’s string-and-tag paper bags or switching to loose-leaf tea with reusable infusers.
Do ants hate tea bags?
Yes—ants are deterred by certain types of tea, especially peppermint. Placing used peppermint tea bags near entry points can help discourage ants naturally. However, this is more of a short-term solution than a permanent fix but you can try these Higgins & Burke peppermint tea bags.
What is a good alternative to tea bags?
If you want to avoid microplastics, reduce waste, or simply enjoy fresher flavour, try:
· Loose-leaf tea (buy from here)
· Compostable tea sachets from eco-conscious brands
· French press brewing for herbal teas and tisanes
These methods let you control portion size and enjoy richer aromas without the potential downsides of bagged tea.
How to tell if tea bags are bad?
Tea bags don’t exactly “spoil” like perishable foods, but they can lose flavour and quality over time. Signs your tea bags have gone bad include:
· A stale or musty smell
· A change in colour of the leaves inside
· Weak or flat taste after brewing
While drinking old tea isn’t usually harmful, the flavour and health benefits may be significantly reduced.
Can mold grow in tea bags?
Yes—especially if tea bags are stored in humid environments or left wet after brewing. Mold thrives in moisture-rich conditions, so keeping tea bags dry and sealed in an airtight container is key.
How to know if a tea bag has mold?
Look for:
· White, grey, or green fuzzy spots
· A sour or earthy odour
· Clumping or dampness in unused bags
If you spot any of these signs, it’s best to discard the tea bag.
Why should you not boil tea bags?
Boiling tea bags can make the tea taste bitter and astringent. The high temperature can also degrade delicate compounds in the tea leaves, reducing flavour complexity. For best results, heat water to the ideal temperature for your tea type—usually between 80°C to 100°C, depending on the variety—and then steep.
Why should you stop throwing away used tea bags?
Used tea bags can be surprisingly useful. Tossing them out means missing opportunities to:
· Fertilize plants (used tea leaves add nitrogen to soil)
· Deodorize spaces (dried tea bags absorb odours in fridges or shoes)
· Soothe skin (cool, damp tea bags can relieve puffy eyes or minor burns)
How to repurpose tea bags?
Here are some creative ways to reuse tea bags:
1. Gardening – Add steeped tea leaves to compost or directly into soil.
2. Cleaning – Use damp tea bags to polish wooden surfaces.
3. Cooking – Infuse rice or pasta water with herbal tea for unique flavours.
4. Pest control – Certain teas deter insects (more on that below).
Why do you not squeeze a tea bag?
Squeezing releases extra tannins, which can make your tea overly bitter. It can also push tiny leaf particles and potential microplastics into your cup. Instead, let the tea bag drip naturally before removing it.
Why shouldn't you leave a tea bag in a cup?
Leaving a tea bag in your cup too long can:
· Over-extract tannins, making the tea taste harsh
· Increase caffeine content beyond what’s desirable
· Cause the bag to break down, releasing particles into your drink
It’s best to follow the recommended steeping time, then remove the bag.
Should you pour water directly on a tea bag?
Pouring water directly on a tea bag is fine—but make sure the water is the right temperature for your tea type. For green tea, cooler water preserves its delicate flavours. For black tea, near-boiling water brings out richness without bitterness. Pouring water over the bag ensures even saturation, helping release flavour quickly.
