The Varies in Caffeine Content
Unlike a standard cup of coffee or tea, a coffee milk tea's caffeine level is not fixed. It is a blend of two potent caffeine sources, tea and coffee, and its final potency depends on several controllable factors. Consumers should be mindful that a seemingly simple beverage could deliver a significant energy boost.
The Tea Base
One of the primary variables is the type of tea used. Black tea is a common base for milk tea and generally contains higher levels of caffeine than green or white tea. An average 8-ounce cup of black tea can contain 40-70mg of caffeine, whereas green tea offers a more modest 20-45mg. The specific black tea variety also matters; for example, Assam tea tends to have a higher caffeine level. Some shops may even use a concentrated, strong brew to stand up to the milk and coffee, further increasing the total caffeine content.
The Coffee Element
Whether a coffee milk tea uses espresso, brewed coffee, or instant coffee makes a substantial difference. A single shot of espresso contains roughly 63mg of caffeine, so a drink with multiple shots can quickly accumulate a high caffeine count. In contrast, brewed coffee will contribute a different amount depending on the preparation. For instance, a stronger cold-brewed coffee may pack a more intense punch than a standard drip coffee. Hong Kong-style milk tea is an example of a brew known for its potent coffee and tea mix.
The Brewing Process
The preparation method is another critical factor. The temperature and duration of steeping affect how much caffeine is extracted from the tea leaves and coffee grounds. Hotter water and longer steeping times will generally result in a more caffeinated beverage. Some recipes, such as the famous Yuenyeung, involve a very strong coffee and tea combination, yielding a powerful brew. A fine grind for coffee or tea also increases surface area, leading to greater extraction.
Coffee Milk Tea vs. Other Caffeinated Drinks
It is useful to compare coffee milk tea's caffeine levels with other popular beverages. This comparison can help manage your daily intake and expectations. A typical coffee milk tea can fall anywhere in the moderate-to-high caffeine range, often surpassing a standard cup of brewed coffee.
| Beverage Type | Serving Size | Approximate Caffeine (mg) |
|---|---|---|
| Coffee Milk Tea | Large (e.g., 16-20 oz) | 100-330mg+ |
| Brewed Coffee | 8 oz cup | 95-100mg |
| Black Tea | 8 oz cup | 40-70mg |
| Espresso | 1.5 oz (double shot) | 150mg |
| Energy Drink | 16 oz can | 80-200mg+ |
Managing Your Caffeine Intake
Whether you are sensitive to caffeine or simply looking to control your intake, there are ways to customize your coffee milk tea to suit your needs. Here are some tips:
- Choose a milder tea base: Opt for a green tea or oolong base instead of black tea for a lower natural caffeine level.
- Request decaffeinated options: Many shops offer decaf coffee or tea versions, allowing you to enjoy the flavour without the stimulant.
- Adjust the strength: Ask for less coffee or tea concentration. Some boba shops offer customizable strength levels.
- Monitor your serving size: A smaller portion will naturally contain less caffeine. Consider ordering a smaller cup to reduce your intake.
- Consider the source: Understand that homemade coffee milk tea can be more potent depending on your recipe, while commercial products might be more standardized.
Conclusion
While a delicious and popular beverage, coffee milk tea is a significant source of caffeine, often exceeding a typical cup of coffee. The caffeine content is highly variable, depending on the tea used, the amount and type of coffee added, and the brewing process. By understanding these factors and making informed choices, consumers can enjoy this drink while effectively managing their caffeine intake.

Frequently Asked Questions
What affects how much caffeine is in coffee milk tea?
Several factors influence the caffeine level, including the type of tea (black vs. green), the amount and type of coffee used (espresso vs. brewed), the brewing temperature, and the steeping duration.
Is coffee milk tea more caffeinated than regular coffee?
It can be. While a standard 8 oz cup of brewed coffee has about 95-100mg of caffeine, a potent coffee milk tea with strong tea and espresso shots can contain significantly more, sometimes over 300mg.
Can I order a low-caffeine coffee milk tea?
Yes, you can. You can request a drink made with a green tea base instead of black tea, or ask for fewer espresso shots. Some shops also offer decaf options for both the coffee and tea.
What is the caffeine content of Hong Kong-style milk tea?
Hong Kong-style milk tea, which is often a strong blend of coffee and tea, has been reported to contain an average of 170mg of caffeine per cup, with some samples containing over 200mg.
Does adding milk to coffee milk tea reduce the caffeine level?
No, adding milk does not reduce the caffeine content. The caffeine is in the brewed coffee and tea, and mixing it with milk or other ingredients only dilutes it but does not remove it from the drink.
Does coffee milk tea give you a faster energy boost than coffee?
Both provide energy, but coffee typically delivers a quicker, more intense kick. The caffeine in tea is absorbed more slowly due to compounds like L-theanine, which provides a smoother energy curve. In a combined drink, the effect can vary.
What is a safe daily limit for caffeine?
For most healthy adults, a daily intake of up to 400 milligrams of caffeine is considered safe. However, individual tolerance varies. Those who are pregnant, breastfeeding, or have certain health conditions should limit their intake and consult a doctor.
