How to Make Cold Brew Tea: Your Complete Guide
When summer temperatures rise, few drinks are as refreshing as a glass of cold brew tea.
Traditional iced tea is brewed hot, then chilled. If you use ice to cool speed up the process, the flavor becomes diluted. Cold brew tea is steeped slowly in cold water over several hours. The result is a smoother, naturally sweeter tea with little to no bitterness.
The best part? It's incredibly easy to make.
If you're wondering what cold brew tea is or how long to cold brew it, this guide covers everything you need to know.
What Is Cold Brew Tea?
Cold brew tea is simply tea that is steeped in cold water instead of hot water. Rather than quickly extracting flavor with heat, cold water slowly draws flavor compounds from the tea leaves over time.
This gentle brewing method creates a tea that is:
- Smooth and refreshing
- Naturally sweeter
- Less bitter
- Easy to prepare
- Perfect for warm weather
Almost any tea can be cold brewed, including green tea, black tea, oolong tea, white tea, and herbal teas.
Green tea can become bitter when brewed with water that is too hot or the steep time is too long. Cold brewing green tea reduces this risk of bitterness. The result is a crisp, refreshing drink that highlights the tea's natural flavor.
How to Make Cold Brew Tea
One reason cold brewing has become so popular is its simplicity.

How Long to Cold Brew Tea
One of the most common questions is how long to cold brew tea.
The answer depends on the type of tea you're brewing.
| Tea Type | Recommended Steeping Time |
| White Tea | 6-8 hours |
| Oolong | 8-10 hours |
| Black Tea | 8-12 hours |
| Green Tea | 8-12 hours |
| Herbal Tea | 8-12 hours |
For most teas, overnight steeping produces excellent results.
If you prefer a stronger flavor, simply allow the tea to steep a little longer.
Why Is Cold Brew Tea So Difficult to Oversteep?
One of the biggest advantages of cold brew tea is that it's incredibly forgiving.
When tea is brewed with hot water, flavor compounds, tannins, and caffeine are extracted quickly. Leave a tea bag in hot water for too long and the tea can become bitter or astringent.
Cold water works differently.
Because cold water extracts flavor much more slowly, the compounds responsible for bitterness are released at a gentler pace. This creates a smoother tea and makes it much harder to accidentally oversteep.
Hot brewed tea steeped too long can quickly become unpleasantly bitter. Cold brew tea left in the refrigerator for a few extra hours will usually still taste refreshing,
For beginners, this forgiving nature is one of the reasons cold brewing is often easier than traditional tea preparation.
Does Cold Brew Tea Have More Caffeine?
Many people assume that steeping tea for several hours must produce more caffeine.
In reality, cold brew tea typically contains slightly less caffeine than hot brewed tea.
Hot water extracts caffeine more efficiently than cold water. While cold brew tea still has caffeine, the slow extraction usually leads to less caffeine than hot brew tea.
Several factors affect caffeine content, including:
- Tea variety
- Amount of tea used
- Steeping time
- Leaf size
- Tea bags versus loose leaf tea
If you're looking for a smooth tea experience with a gentler caffeine profile, cold brewing can be an excellent option.
Is Cold Brew Better With Tea Bags or Loose Leaf Tea?
The answer depends on what matters most to you.
Tea Bags: Best for Convenience
Tea bags make cold brewing incredibly simple.
Just drop them into water, refrigerate, and remove them when brewing is complete.
Tea bags are ideal for:
- Beginners
- Single servings
- Quick preparation
- Travel
- Minimal cleanup
Loose Leaf Tea: Best for Flavor
Loose leaf tea always provides a richer and more nuanced flavor experience.
Because the leaves have more room to expand during brewing, they can release a wider range of flavors and aromas.
Loose leaf tea is ideal for:
- Tea enthusiasts
- Premium tea varieties
- Flavor exploration
- Customizing brewing strength
Cold Brew Tea Pouches: The Best of Both Worlds
Cold brew tea pouches offer the ease of tea bags with the many flavor of whole leaf tea.
They offer:
- Easy cleanup
- No measuring
- Excellent flavor extraction
- Convenient pitcher brewing
- Consistent results
For many tea drinkers, cold brew pouches provide the perfect balance between convenience and flavor.
Best Teas for Cold Brewing
Most think of black tea when it comes to iced tea. But nearly any tea can be cold brewed. Some varieties are particularly refreshing.
Green Tea
Green tea is one of the most popular choices for cold brewing. The process helps reduce bitterness while highlighting the tea's natural sweetness and fresh flavor.
Jasmine Green Tea Pearls release a floral aroma that is especially crisp and refreshing when served cold.
Bright citrus notes of Jade Citrus Mint tea pair perfectly with the smooth character of cold brew tea.
Vanilla Oolong Tea
Cold brewing enhances the creamy vanilla notes while maintaining a light, refreshing finish.
Herbal Teas

Common Cold Brew Tea Mistakes
Using Too Little Tea
Cold water extracts flavor more slowly than hot water. Don't be afraid to use an extra tea bag or additional tea leaves if you prefer a stronger brew.
Using Poor Quality Water
Filtered water often produces the cleanest tasting tea.
Leaving Tea at Room Temperature
For best results, always brew tea in the refrigerator. Steeping with room temperature water extracts flavor and caffeine a bit faster than steeping in the fridge. It still takes longer than using boiling water.
Sun Steeping
Sun-steeping isn’t recommended. In most cases, the water warms only to about 105°F–130°F. This range produces an ideal environment for bacterial growth.
That lukewarm temperature squarely in the “danger zone”. Disease-causing organisms—such as E. coli—can reproduce quickly at that temperature and reach unsafe levels.
Forgetting to Experiment
One of the joys of cold brewing is experimentation. Discover how different teas develop unique flavor profiles when brewed slowly in cold water.
