Your Guide to Caffeinated Teas at Starbucks
For those who prefer a clean, smooth, or spiced energy boost over coffee's intensity, Starbucks offers a diverse and surprisingly caffeinated tea menu. Beyond the familiar Chai and Matcha Lattes, the menu includes classic iced teas and new, high-caffeine Iced Energy drinks. Understanding the caffeine content and characteristics of each can help you find the perfect beverage for your energy needs.
The Heavy-Hitters: High-Caffeine Tea Lattes
When it comes to a significant and noticeable jolt of energy, two drinks stand out: the Matcha and Chai Tea Lattes. These are often the first stop for anyone asking what tea gives you energy at Starbucks.
- 
Chai Tea Latte: Made with black tea concentrate, this creamy, spiced favorite delivers a powerful caffeine punch. A grande size contains about 95mg of caffeine, putting it on par with a standard cup of brewed coffee. The energy from the black tea is complemented by spices like cinnamon and clove, creating a warm, comforting, and energizing experience. For an even stronger kick, some customers order a "Dirty Chai," which includes a shot of espresso. 
- 
Matcha Green Tea Latte: This is another top contender for caffeine, offering a different kind of energy. Because matcha is a powdered green tea where you consume the entire leaf, it has a high concentration of both caffeine and L-theanine. L-theanine is an amino acid that promotes a state of calm alertness, mitigating the jittery effects sometimes associated with caffeine. A grande Iced Matcha Latte has around 65mg of caffeine, providing a smooth and sustained energy boost without a harsh crash. You can also ask for extra scoops of matcha for an increased caffeine level at no extra charge. 
Modern Alternatives: Sparkling Iced Energy
For a more modern, fruit-forward, and sparkling lift, Starbucks introduced its line of handcrafted Iced Energy drinks in 2024. These drinks feature a high amount of plant-based caffeine.
- 
Tropical Citrus Iced Energy: This option combines bright citrus and passionfruit flavors with a green tea base. For a venti size, it offers a robust caffeine boost comparable to a grande cold brew, containing between 180-205mg of caffeine. It is sugar-free and only 5 calories, making it a powerful and light energy option. 
- 
Melon Burst Iced Energy: Featuring flavors of melon and cucumber with a Passion Tango tea base, this sparkling drink is another potent, zero-sugar energy choice. Similar to the Tropical Citrus flavor, a venti provides a significant caffeine hit. 
The Lighter Choices: Brewed Iced and Hot Teas
If you're seeking a milder, more subtle lift, Starbucks' standard brewed teas are a great choice. They are excellent for a gentle afternoon boost or for hydrating with a splash of caffeine.
- 
Iced Black Tea: A straightforward option, a grande Iced Black Tea contains around 25-30mg of caffeine, offering a classic tea flavor with a moderate boost. Ordering it with light ice can provide a slightly higher concentration of tea and caffeine. 
- 
Iced Green Tea: The Iced Green Tea is lighter in caffeine, with a grande containing about 25-30mg. It is refreshing and provides a minimal energy lift. 
- 
Hot Royal English Breakfast Tea: For a traditional hot brew, the Royal English Breakfast tea is a reliable choice. The caffeine content varies depending on how long it's steeped, but it is derived from black tea, which generally contains higher levels of caffeine than green or white tea. 
Comparison of Starbucks Caffeinated Teas (Grande Size)
| Drink | Caffeine (mg) | Energy Profile | Flavor Profile | 
|---|---|---|---|
| Chai Tea Latte | ~95 | Strong, steady boost | Warm, spiced (cinnamon, clove) | 
| Matcha Green Tea Latte | ~65 | Clean, sustained focus | Earthy, vegetal, slightly sweet | 
| Iced Black Tea | 25-30 | Gentle, subtle lift | Classic, robust black tea | 
| Iced Green Tea | 25-30 | Mild, hydrating boost | Light, fresh green tea | 
| Royal English Breakfast Tea | Varies | Traditional, moderate lift | Full-bodied, malty black tea | 
| Tropical Citrus Iced Energy | 180-205 (Venti) | Strong, sparkling kick | Fruity, tart citrus and passionfruit | 
How to Maximize Your Tea's Energy
For those who need an extra push, there are several ways to customize your Starbucks tea to increase its caffeine content:
- Add an Espresso Shot: A "dirty" chai or matcha is a popular off-menu modification. Adding a shot of espresso to either your Chai Tea Latte (making it a Dirty Chai) or your Matcha Latte can significantly boost the total caffeine. A single shot of Starbucks signature espresso has about 75mg of caffeine.
- Order Extra Matcha Scoops: If you're a fan of the matcha flavor, simply ask for an extra scoop or two of matcha powder. Each scoop adds approximately 27mg of caffeine and does not come with an additional charge when added to a matcha beverage.
- Request "Light Ice": For iced teas, less ice means more liquid tea concentrate is used. This is a simple and free trick to get a slightly higher dose of caffeine.
- Double the Tea Bags: When ordering hot brewed tea, you can ask for two tea bags instead of one to increase the steeping strength and caffeine extraction.
Conclusion
Whether you need a powerful morning stimulant or a gentle afternoon pick-me-up, Starbucks has a tea for you. For the highest caffeine content in a classic tea drink, the Chai Tea Latte is your best bet, providing a spicy and warm boost. If you prefer a clean, focused energy with less chance of a crash, the Matcha Green Tea Latte is an excellent choice due to its L-theanine content. For a modern, high-intensity energy drink, the new Iced Energy beverages pack the most punch, though they contain plant-based caffeine rather than tea leaves. By knowing your options and utilizing simple customization techniques, you can confidently navigate the menu and get exactly what you need to power your day.
