How to Make Cold Brew Tea at Home

Ingredients and Tools You’ll Need

Making cold brew tea requires only a few simple items:

Ingredients:

• 1–2 teaspoons loose-leaf tea or 1 tea bag per cup (8 oz) of water

• Fresh, cold filtered water

• Optional: lemon slices, mint, honey, or fruit for flavor

Tools:

• Glass jar, pitcher, or bottle

• Tea infuser (for loose-leaf tea)

• Refrigerator

• Fine strainer (if not using an infuser)

That’s it—no kettle required!

Step-by-Step Guide: How to Make Cold Brew Tea

1. Measure Your Tea

A good starting ratio is:

• 1 teaspoon loose-leaf tea per 8 ounces of water

• Or 1 tea bag per 8–12 ounces of water

If you prefer stronger tea, slightly increase the amount of tea rather than steeping too long.

2. Add Cold Water

Place your tea in a jar or pitcher and pour cold, filtered water over it. Make sure all leaves are fully submerged.

Filtered water makes a noticeable difference in taste, especially since cold brewing highlights subtle flavors.

3. Steep in the Refrigerator

Cover the container and place it in the refrigerator.

Steeping times vary depending on the type of tea:

• Green tea: 6–8 hours

• Black tea: 8–12 hours

• White tea: 6–8 hours

• Herbal tea: 8–12 hours

Avoid steeping longer than 12–14 hours, as the flavor can become flat or overly strong.

4. Strain and Serve

Once steeped, remove the tea bag or strain out loose leaves. Pour over ice if desired, or enjoy it straight from the refrigerator.

You can store cold brew tea in the fridge for up to 3 days for the freshest taste.

Best Teas for Cold Brewing

Almost any tea works for cold brewing, but some varieties truly shine.

Green Tea

Light, grassy, and refreshing. Cold brewing reduces bitterness and enhances its natural sweetness.

Black Tea

Smooth and bold without the harsh tannins that sometimes come from hot brewing.

White Tea

Delicate and floral. Cold brewing preserves its subtle flavor profile beautifully.

Herbal Tea

Caffeine-free options like chamomile, hibiscus, peppermint, or fruit blends create vibrant, refreshing drinks.

Experimenting with different teas allows you to discover new flavor combinations.

Why Cold Brew Tea Tastes Better

Cold water extracts fewer tannins - the compounds responsible for bitterness and dryness in tea. Heat accelerates tannin release, which can sometimes overpower delicate notes.

With cold brewing:

• Flavor extraction is slower and gentler

• Bitterness is reduced

• Sweet and floral notes are more noticeable

The result is a naturally smooth beverage that often requires little or no sweetener.

Tips for Perfect Cold Brew Tea

To elevate your cold brew tea, keep these tips in mind:

Use Quality Tea

High-quality loose-leaf tea generally produces better flavor than low-grade tea bags.

Use Filtered Water

Impurities in tap water can dull or alter the taste.

Don’t Over-Steep

Longer is not always better. Follow recommended times for optimal balance.

Try Fruit Infusions

Add sliced strawberries, oranges, cucumber, or mint during the steeping process for a naturally flavored twist.

Make It Sparkling

After straining, mix with sparkling water for a refreshing fizzy tea.

Cold Brew Tea vs Iced Tea

Though often confused, cold brew tea and iced tea are different.

Iced Tea:

• Brewed hot, then cooled

• Stronger and sometimes more bitter

• Faster to prepare

Cold Brew Tea:

• Steeped in cold water

• Smoother and less acidic

• Takes longer but requires less effort

If you prefer a mellow and refreshing drink, cold brew tea is an excellent choice.

Health Benefits of Cold Brew Tea

Cold brew tea offers many of the same benefits as traditionally brewed tea:

• Rich in antioxidants

• Supports hydration

• May support heart health

• Contains natural compounds that promote relaxation

Because it’s less bitter, you may not need added sugar—making it a healthier alternative to many store-bought beverages.

Herbal cold brew teas also provide caffeine-free options for evening enjoyment.

Frequently Asked Questions

Can you cold brew tea at room temperature?

Yes, but refrigeration is recommended to prevent bacterial growth and maintain freshness.

Is cold brew tea stronger?

It can be smoother but not necessarily stronger. Strength depends on the tea-to-water ratio and steeping time.

Can you reuse tea leaves?

You can sometimes reuse high-quality loose leaves for a second, lighter batch, but flavor will be milder.

Does cold brew tea have less caffeine?

It often contains slightly less caffeine than hot-brewed tea because caffeine extracts more efficiently in hot water.
