How Much Caffeine Is in Chai Tea? (Earl Grey & Thai Tea Too)
Yes, chai tea contains caffeine. The caffeine comes entirely from the black tea base that is the foundation of every traditional masala chai recipe. The spices (cardamom, cinnamon, ginger, cloves, pepper) contribute no caffeine. So the amount of caffeine in your cup depends on the strength of the tea base, how much tea you use, and how long you steep it.
How Much Caffeine Is in Chai Tea?
| Tea Type | Caffeine per 8oz | Notes |
|---|---|---|
| Chai Tea (loose leaf) | 40 to 70 mg | Depends on base and steep time |
| Earl Grey | 40 to 60 mg | Ceylon or Darjeeling base |
| Thai Tea | 40 to 60 mg | Strong Ceylon base, often served with sweetened milk |
| Strong Assam Black Tea | 50 to 70 mg | Higher with longer steep |
| Drip Coffee | 80 to 100 mg | For comparison |
| Espresso (2oz) | 60 to 70 mg | For comparison |
A standard 8-ounce cup of chai brewed from quality loose leaf sits at about 40 to 70 mg of caffeine. That is roughly comparable to a moderate black tea and about half to two-thirds the caffeine of a typical cup of drip coffee.
Why Chai Feels More Stimulating Than Plain Black Tea
Many people report that a cup of chai feels more energizing than a plain black tea with the same amount of tea leaf. The reason is almost certainly the spices.
Ginger has a mild stimulating effect on circulation and digestion. Cardamom and black pepper have alerting, aromatic qualities that engage the senses before the caffeine even takes effect. The overall warmth of a chai blend creates a full-body sensory experience that a plain black tea does not. The caffeine is doing the actual stimulating work, but the spice profile makes it feel like more is happening.
This is also why chai works so well as a morning drink: the combination of moderate caffeine and activating aromatics produces a complete waking-up experience rather than just a caffeine delivery mechanism.
Chai Latte vs Brewed Chai: Caffeine Differences
A chai latte from a coffee shop is typically made with a concentrated chai syrup mixed with steamed milk. The caffeine content depends heavily on how much tea concentrate is in the syrup and how much concentrate the shop uses per serving. Commercial chai lattes can range from 50 to 120 mg of caffeine per serving depending on the brand and recipe.
A home-brewed chai from quality loose leaf tea is more controllable. You choose the amount of leaf (1 to 2 teaspoons per cup is standard), the steep time (3 to 5 minutes is typical), and the water temperature (near boiling). This gives you a predictable caffeine level in a way that a pre-made syrup does not.
Our Chai-huahua Spice is a hand-blended masala chai with an Assam black tea base. Brewed at 1.5 teaspoons per cup for 4 minutes, it produces a robust, spicy cup with approximately 50 to 65 mg of caffeine.
How Much Caffeine Is in Earl Grey?
Earl Grey uses a lighter base than traditional Assam chai (typically Ceylon or Darjeeling), which produces a slightly lower caffeine level: roughly 40 to 60 mg per 8-ounce cup. The bergamot oil that gives Earl Grey its signature citrus aroma is purely a flavoring and contributes no caffeine.
Our Earl Greyhound uses premium Darjeeling and Ceylon bases with high-quality bergamot oil, producing a balanced cup with a moderate caffeine profile that works well as a morning or mid-morning drink.
How Much Caffeine Is in Thai Iced Tea?
Traditional Thai iced tea is made with a strong brew of Ceylon black tea (or a Thai tea blend), often steeped at a high leaf-to-water ratio, then poured over ice with sweetened condensed milk or evaporated milk. The base brew tends to be strong: roughly 40 to 60 mg of caffeine per 8 ounces of tea, though the final drink is often diluted with ice and milk to a total of around 30 to 50 mg per serving.
Our Thai Tails and Trails is a Thai-inspired blend that captures the warm, slightly floral-spiced character of Thai tea for home brewing.
Does Chai Have Less Caffeine Than Coffee?
Yes, in most cases. A standard cup of chai (40 to 70 mg) has about half to two-thirds the caffeine of a standard drip coffee (80 to 100 mg). If you drink a 12-ounce chai latte made from scratch, you are still generally below a single 12-ounce coffee in total caffeine.
For people who want to reduce their caffeine intake without giving up a warm, flavorful morning drink, chai is a practical middle ground. For those who want to eliminate caffeine entirely, our Citrus Setter Rooibos and Chamomile Flowers are completely caffeine-free options that still deliver warmth and flavor.
