Yes, most milk teas contain caffeine. The amount varies depending on several factors, including the type of tea used (black tea generally has more caffeine than green tea), the concentration of the tea, and the serving size.
Caffeine Content in Milk Tea
- Variations: While some milk teas contain high concentrations of caffeine (around 150 mg per 470 mL serving, as found in some tests), others have significantly less. This depends heavily on the tea base. For example, Thai milk tea, made with black tea, can contain 30-60 mg of caffeine, while milk teas using green tea will have less.

Factors Affecting Caffeine Content:
