Thai Iced Tea Caffeine Content
Thai iced tea is built on black tea, so it carries real caffeine - but usually less than a coffee. A typical glass lands around 20-60 mg. Here is what drives the range and how it stacks up.
The quick numbers
A standard glass of Thai iced tea made with about 4 tablespoons of mix per two servings delivers roughly 20 to 60 mg of caffeine per glass. The wide range exists because vendors and recipes vary enormously in how much tea they use and how long they steep.
| Drink | Typical caffeine |
|---|---|
| Thai iced tea (1 glass) | ~20-60 mg |
| Brewed coffee (8 oz) | ~95 mg |
| Espresso (1 shot) | ~63 mg |
| Matcha (1 tsp) | ~60-70 mg |
| Black tea (8 oz) | ~47 mg |
| Cola (12 oz) | ~34 mg |
What changes the caffeine in your cup
- Amount of mix. More tea, more caffeine - the single biggest factor.
- Steep time. A 5-minute steep extracts noticeably more than 2-3 minutes.
- Water temperature. Hotter water pulls caffeine faster.
- Ice melt. A heavily iced glass dilutes the concentration per sip.
Brew it yourself to control the dose
Making it at home is the only way to actually know your caffeine. Start with a good mix and adjust the quantity to taste.
Consistent strength so you can dial your caffeine in by the tablespoon.

Use less mix, steep for 3 minutes instead of 5, or blend in a caffeine-free roasted barley or rooibos to bulk the flavor without the buzz. A decaf black tea base also works, though the spiced character softens.
FAQ
Is Thai tea high in caffeine?
Moderate. It generally has less caffeine than a cup of coffee but more than a cola, depending on how strong it is brewed.
Can kids drink Thai iced tea?
It does contain caffeine and a lot of sugar, so it is best treated as an occasional drink for children rather than a daily one.
Does the milk reduce caffeine?
No - milk does not remove caffeine, it only changes flavor and texture. Dilution from ice is what lowers the per-sip concentration.
