Cold-brew tea has quickly transformed from a niche trend into a daily essential for many people. Whether you prefer a cleaner flavor profile, want something easy on the stomach, or simply enjoy a refreshing drink throughout the day, cold-brew tea has become one of the most popular ways to enjoy tea.
In this guide, we’ll explore why cold-brew tea is rising in popularity, its benefits, how to make it with loose leaves or tea bags, which teas work best, and an emerging quick-brew alternative known as “Fresh-Shake Tea.”
Why Cold-Brew Tea Is Becoming So Popular
1. Less Bitterness and Astringency
Traditional hot brewing extracts more tannins, higher caffeine and bitter compounds because of the higher temperature. Cold-brew tea, however, uses room-temperature or chilled water, releasing fewer harsh components.
The result is a naturally smoother, sweeter and rounder flavor with noticeably less bitterness.
2. Low Tannins, Gentler for Sensitive Stomachs
Tannins are responsible for the dryness or “scratchy” feeling some people get from hot tea. Cold-brewing significantly reduces tannin extraction, making the tea more soothing and easier to digest.
For people with sensitive stomachs or those looking for a lighter drinking experience, cold-brew offers a much gentler alternative.
3. Lower Caffeine Extraction
Caffeine is extracted more slowly at lower temperatures. This means cold-brew tea usually contains less caffeine, making it suitable for all-day drinking and less likely to affect sleep.
4. Cleaner and Fresher Aroma
Cold-brewing highlights delicate notes that are often overshadowed in hot brews. Floral, milky, grainy or vegetal aromas come through more clearly, depending on the tea type.
It creates a refreshing, subtle and clean taste that works well year-round.
How to Make Cold-Brew Tea
Cold-brew tea is simple and reliable whether you prefer loose-leaf tea or convenient tea bags.
Method 1: Loose-Leaf Cold-Brew
- Use about 1 gram of tea per 50–100 mL of water (for example, 10g tea for 500–1000mL water).
- Steep in the refrigerator or at room temperature for 4–10 hours depending on the tea.
- Strain and enjoy.
This method draws out the deeper character and complexity of high-quality tea leaves.
Method 2: Tea-Bag Cold-Brew
Tea bags are now one of the most popular ways to cold-brew because of their convenience.
- Add one tea bag (3–7g depending on the type).
- Pour in 500–1000 mL of cold water.
- Refrigerate for 4–12 hours.
Tea-bag cold-brew is clean, fast and consistent, making it ideal for daily hydration and busy routines.
Best Tea Types for Cold-Brewing
Certain teas perform exceptionally well when cold-brewed:
Oolong Teas
Light-floral or lightly roasted oolongs become soft, aromatic and smooth when brewed cold.
Green Teas
Cold-brewing reduces the bitterness and enhances clean notes like seaweed, soybean and meadow-fresh aromas.
Grain and Roasted Teas
Barley tea, buckwheat tea, roasted black bean tea and grain blends deliver a naturally toasty, nutty profile. Many are caffeine-free, making them suitable for evening drinking.
Herbal and Rooibos Blends
Cold-brew highlights gentle floral, citrus or botanical notes, producing a bright, refreshing cup.
