Does Chai Tea Have Caffeine? The Ultimate Guide
A 240 ml serving of chai latte contains 50 mg of caffeine.
- 240 ml chai latte ≈ 50 mg caffeine (dataset value).
- Plain black tea (240 ml) ≈ 47 mg; masala chai made with black tea will be similar.
- A 240 ml cup of drip coffee has 96 mg, about twice the caffeine in a chai latte.
- After 6 hours roughly 48% of a caffeine dose remains (population-average).
What is chai tea?
Chai (Hindi: "tea") typically refers to spiced tea made by brewing black tea leaves with milk and a mix of spices (cardamom, cinnamon, ginger, cloves). In many Western cafés "chai latte" is the steamed-milk version of that brew; the dataset entry "chai latte | 240 ml | 50 mg" matches that common café serving. Traditional masala chai uses a black tea base, so its caffeine profile follows black tea more than herbal or rooibos blends.
Caffeine content in traditional masala chai
When masala chai is brewed from black tea, expect caffeine close to the black tea benchmark in our dataset: 240 ml black tea = 47 mg. Commercial chai lattes are formulated to deliver a consistent caffeine amount; the dataset lists a 240 ml chai latte at 50 mg. Differences of ±10–20% are normal depending on leaf quantity and steep time.
How chai compares to other teas and coffee
Use the table below to compare common beverages in the dataset. These exact numbers come from the supplied dataset and public compositions like USDA/FoodData Central for tea types.
| Drink (serving) | Volume | Caffeine (mg) |
|---|---|---|
| Chai latte | 240 ml | 50 mg |
| Black tea | 240 ml | 47 mg |
| Matcha (1 tsp) | 240 ml | 70 mg |
| Green tea | 240 ml | 28 mg |
| Drip coffee | 240 ml | 96 mg |
| Cold brew | 240 ml | 200 mg |
| Espresso (single) | 30 ml | 63 mg |
Variations of chai and their typical caffeine levels
Masala chai (black‑tea base)
Masala chai brewed with standard black tea will fall near the black tea value (≈47 mg per 240 ml). Stronger blends, more tea leaves, or longer boiling increase extraction and raise caffeine; shorter brews reduce it.
Chai latte (café style)
The dataset lists chai latte at 50 mg per 240 ml — that’s a practical baseline for café servings. Many chains use a concentrated tea syrup or tea‑espresso blend; check nutrition info for exact numbers.
Decaf or herbal chai
Rooibos or other herbal chai blends contain 0 mg (dataset: herbal tea 240 ml = 0 mg). Decaffeinated black‑tea chai will still have trace caffeine — not listed in the dataset — so treat decaf chai as a low‑but‑not‑zero option and consult specific brand data.
What affects caffeine in chai?
- Tea variety: black teas (English Breakfast, Earl Grey) are ~47–50 mg/240 ml in the dataset; oolong and green are lower.
- Leaf amount and steep time: more leaves and longer steeping extract more caffeine.
- Preparation method: boiling tea in milk (traditional masala chai) extracts differently than a quick steep or syrup concentrate.
- Serving size: a large (350–473 ml) serving multiplies the per‑cup number — always check volume.
How long does caffeine from chai last? (decay math)
Caffeine elimination follows first‑order kinetics in populations; use a 5.7‑hour half‑life as the average. The dataset values plus standard decay multipliers give concrete remaining amounts.
| Time after 50 mg dose | % remaining | mg remaining (50 mg) |
|---|---|---|
| 3 hours | ≈69% | ≈34.5 mg |
| 6 hours | ≈48% | ≈24 mg |
| 9 hours | ≈33% | ≈16.5 mg |
| 12 hours | ≈23% | ≈11.5 mg |
For a higher‑caffeine drink like 240 ml cold brew (200 mg in the dataset), the same multipliers give:
| Time after 200 mg dose | % remaining | mg remaining (200 mg) |
|---|---|---|
| 3 hours | ≈69% | ≈138 mg |
| 6 hours | ≈48% | ≈96 mg |
| 9 hours | ≈33% | ≈66 mg |
| 12 hours | ≈23% | ≈46 mg |
Health, safety and timing vs. sleep
Authoritative limits: FDA recommends ≤400 mg/day for healthy adults; some authorities (e.g., U.S. and European guidance) advise ≤200 mg/day during pregnancy. The American Academy of Pediatrics discourages caffeine use in adolescents. One 240 ml chai latte at 50 mg is well under the 400 mg limit, but multiple caffeinated beverages add up quickly.
Timing: because ~48% remains after 6 hours, an evening chai can still contain substantial caffeine at bedtime and disturb sleep. If sleep is a concern, choose herbal chai (0 mg) or decaf alternatives earlier in the day.
Practical tips and tracking
To lower caffeine in chai: use fewer tea leaves, shorter steep, or a rooibos/herbal base. To estimate your daily intake, add dataset values for each beverage you drink. Apps like CoffeeLog automate logging and calculate remaining caffeine over time so you can plan drinks relative to sleep or pregnancy limits.

Frequently asked questions
Do chai teas have caffeine?
Yes. Masala chai made with black tea and a 240 ml chai latte both contain caffeine — the dataset lists chai latte at 50 mg/240 ml and black tea at 47 mg/240 ml.
Is chai stronger than coffee?
No. A 240 ml chai latte (50 mg) has about half the caffeine of a 240 ml drip coffee (96 mg) in the dataset. Espresso shots (63 mg per 30 ml) are more concentrated by volume.
Can I get caffeine‑free chai?
Yes. Rooibos or herbal chai blends contain 0 mg (dataset: herbal tea 240 ml = 0 mg). Decaffeinated black‑tea chai will have small traces and depends on brand.
How long does chai caffeine affect me?
Using a population half‑life of 5.7 hours, about 48% remains after 6 hours. From a 50 mg chai, roughly 24 mg remains at 6 hours and ~11.5 mg at 12 hours.
Is chai safe during pregnancy?
Guidance commonly recommends limiting caffeine to about 200 mg/day during pregnancy. One 240 ml chai latte at 50 mg is within that, but total daily intake matters; consult your provider.
How can I track my chai caffeine intake?
Log serving sizes and beverage types and add the dataset values. Tools like CoffeeLog can automate entries and show cumulative caffeine and remaining mg over time.
