What Is Cold Brew Tea?

Cold brew tea is made by steeping tea leaves in cold or room temperature water for 6 to 12 hours, instead of using hot water. This slow extraction process creates a lighter, sweeter flavor and preserves certain nutrients that can be damaged by heat.

Cold brewing helps preserve polyphenols and reduces tannin extraction, making tea smoother and easier on the stomach.

Top Cold Brew Tea Benefits

1. High in Antioxidants

Cold brewing preserves more catechins, EGCG, and flavonoids—especially in green and white tea—compared to hot brewing at high temperatures.

These compounds:

Fight oxidative stress
Support immune health
May reduce inflammation and cellular aging

Catechins like EGCG in green tea are associated with lower risks of cardiovascular disease and metabolic issues.

2. Lower Caffeine, Same Focus

Cold brew extracts less caffeine than hot water, which makes it ideal for those wanting:

Gentle alertness without jitters
A calmer energy boost
Evening or late-afternoon sipping

Cold-brewed tea contains about 30–50% less caffeine than hot tea brewed for the same duration.

3. Easier on the Stomach

Less heat means fewer tannins are extracted, which reduces:

Stomach upset
Acid reflux triggers
Astringent or dry mouthfeel

This makes cold brew tea a great choice for sensitive stomachs or those who don’t enjoy strong, bitter teas.

4. Hydration with Benefits

Cold brew tea is hydrating and rich in electrolytes (especially when using herbal blends like hibiscus, rooibos, or mint). It can:

Support hydration during hot weather or workouts
Add variety without sugar or calories
Replace soda or energy drinks

Herbal teas like hibiscus and rooibos are naturally caffeine-free and rich in antioxidants and electrolytes.
