Chai Tea Caffeine: How Much Is in Your Cup?
Posted by Ricardo R. Matos, Founder of Tea The World on Apr 3rd 2025
Quick answer: A cup of chai made with black tea usually has about 40–70 mg of caffeine per 8 oz, roughly half of a typical cup of coffee. The exact amount depends on the tea, how much you use, and how long you simmer it.
The Origins of Chai
“Chai” simply means “tea” in Hindi. Masala chai, the spiced version loved around the world, is black tea simmered with spices such as cardamom, cinnamon, ginger, cloves, and black pepper, then mixed with milk and sugar. Every family has its own recipe.
Understanding Caffeine
Caffeine is a natural stimulant found in tea, coffee, and cacao. You can feel it within about 15 minutes, and its effects can last for hours. Moderate amounts boost alertness, but too much can cause jitteriness, anxiety, or trouble sleeping. Sensitivity varies from person to person.
Caffeine in Different Types of Tea (per 8 oz)
| Tea Type | Typical Caffeine |
|---|---|
| Black tea (classic chai base) | 40–70 mg |
| Green tea | 20–45 mg |
| Oolong tea | 30–50 mg |
| White tea | 15–30 mg |
| Herbal tea | 0 mg |
Chai blends made with an herbal base like rooibos are caffeine-free.
What Affects Caffeine in Chai
- Tea leaves: Assam, Ceylon, and other black teas vary in caffeine.
- Brewing method: Simmering longer extracts more caffeine.
- Tea-to-water ratio: More leaf means more caffeine.
- Commercial mixes and concentrates: These vary widely, so check labels.
Chai vs. Other Drinks (Approximate)
| Beverage | Caffeine |
|---|---|
| Chai (black tea, 8 oz) | 40–70 mg |
| Brewed coffee (8 oz) | about 95 mg |
| Espresso (1 shot) | about 63 mg |
| Energy drink (8 oz) | 70–80 mg |
| Cola (12 oz) | 30–40 mg |
What Research Says About Chai’s Ingredients
- Black tea: Contains polyphenols, and observational studies link regular tea drinking with heart health (associations, not proof).
- Ginger: Studied for easing nausea, mostly in supplement form.
- Cinnamon: Studied for modest effects on blood sugar, usually at supplement doses far above what’s in a cup of chai.
- Cardamom, cloves, and pepper: Aromatic spices with traditional digestive uses.
Traditional chai also includes milk and sugar, so adjust the sweetness to suit your goals.
How to Make the Perfect Cup of Chai
- Bring 1–2 cups of water to a boil in a saucepan.
- Add whole or crushed spices and simmer for a few minutes.
- Add 1–2 teaspoons of loose black tea and simmer 3–5 minutes.
- Add milk and sugar to taste (traditionally about 1 part milk to 2 parts water).
- Bring to a gentle boil, then simmer a couple more minutes.
- Strain and serve hot.

Tips for Less Caffeine
- Use decaffeinated black tea (usually about 2–5 mg per cup).
- Use rooibos as a caffeine-free base for chai spices. Try Green Rooibos Bonita.
- Use less tea or simmer for a shorter time.
