Chai Latte Caffeine: How Much Is in Your Drink?

A standard 240 ml chai latte contains 50 mg of caffeine.

• 240 ml chai latte = 50 mg caffeine (dataset value).
• Compared to drip coffee (240 ml = 96 mg) a chai latte has ~46 mg less caffeine.
• After 6 hours about 24 mg remains from a 50 mg chai latte (population half-life ≈ 5.7 h).
• FDA recommends healthy adults limit caffeine to 400 mg/day; pregnancy guidance ≈ 200 mg/day

How much caffeine is in a chai latte?

The dataset standard for "Chai latte" is 240 ml with 50 mg of caffeine. That number reflects a typical milk-based brew made from spiced black tea concentrate plus milk. Because chai is made with black tea as the base, its caffeine is similar to milder black tea servings rather than espresso-based lattes.

Chai latte versus common coffee and tea drinks

To understand where a chai latte sits on the spectrum, this table lists a mix of coffee, tea and chai values from the dataset so you can compare serving-for-serving.

This shows chai lattes sit close to a cup of black tea (240 ml black tea = 47 mg) and are substantially lower than typical brewed coffee or cold brew.

Starbucks, chains and homemade chai — what to expect

The dataset does not list a Starbucks chai latte specifically; do not assume Starbucks chai equals the dataset chai. Chain espresso lattes and flat whites are much higher in caffeine: for example, Starbucks Caffè Latte (Grande, 473 ml) = 150 mg, Starbucks Flat White (Grande, 473 ml) = 195 mg. A homemade chai latte will depend on tea strength, amount of concentrate or bags, and portion size; USDA FoodData Central lists typical black tea values, which helps estimate when a recipe is unknown.

Estimating homemade chai

If you brew strong black tea (two tea bags in 240–300 ml) you can approach or exceed 60–70 mg; a single standard steep yields nearer 40–50 mg. Use trackable logging (for example, CoffeeLog) to record how many tea bags or shots you use and get a precise running total.

How caffeine from a chai latte decays over time

Use the population-average half-life of caffeine ≈ 5.7 hours to estimate how much remains after sleep or between drinks. The rule-of-thumb percentages: ~69% at 3 h, ~48% at 6 h, ~33% at 9 h, ~23% at 12 h.

Example: a 50 mg chai latte consumed at 6 pm would leave roughly 24 mg of caffeine in an average adult’s system by midnight. Individual metabolism varies due to genetics, medications, and liver function (CYP1A2 activity).

What affects chai latte caffeine?

Primary factors that change caffeine in a chai latte:

• Tea strength and quantity — more tea bags or a longer steep increases mg.
• Type of black tea — some blends or Assam-forward mixes deliver higher caffeine per ml than lighter blends; the dataset lists black tea at 47 mg per 240 ml as a baseline.
• Serving size — a 240 ml single is 50 mg; double-size drinks or concentrate-heavy recipes scale up linearly.
• Espresso addition — some chains add espresso shots; a single espresso shot in the dataset is 63 mg (30 ml), which would dramatically raise total caffeine.

Decaf and lower-caffeine chai options

Decaf coffee in the dataset is 240 ml = 3 mg, showing decaffeination reduces caffeine but usually does not eliminate it. For chai, use decaffeinated black tea or caffeine-free rooibos to get near-zero caffeine. You can also reduce steep time or use a single weak tea bag to lower caffeine to the 20–30 mg range (estimate).

Health, safety, and timing

FDA guidance for healthy adults sets ~400 mg/day as an upper daily limit; pregnant people are commonly advised to limit to ~200 mg/day (see FDA and some obstetric guidance). The American Academy of Pediatrics discourages regular caffeine for adolescents. For those with anxiety, arrhythmia, pregnancy, or on interacting medications, consult a clinician before increasing caffeine intake.

Because a 240 ml chai latte is 50 mg, it is modest within those limits: four such drinks equal 200 mg; eight equals the 400 mg upper limit. Track cumulative intake across coffee, tea and energy drinks — for example, a single 473 ml Starbucks Pike Place Brewed (Grande) = 310 mg per the dataset and can push daily totals quickly.

Practical tips to manage caffeine from chai

• Order smaller sizes or request fewer tea bags/shots if you want lower caffeine.
• Choose decaf or rooibos for late-afternoon or evening drinks to protect sleep.
• Use a tracker like CoffeeLog to sum mg from different sources automatically: chai (50 mg) + espresso shots (63 mg each) + coffee adds up fast.
