Traditional chai is made from a strong black tea base, so it contains caffeine (typically 30–50 mg). If you order a "dirty chai" or a chai latte with an added espresso shot, the caffeine content will be significantly higher (100mg+).

Drink sizes are in fluid ounces (oz.) and milliliters (mL). Experts say up to 400 milligrams (mg) of caffeine a day may be safe for most adults. But if you get headaches or are restless or nervous after having caffeine, you may want to rethink how much caffeine is right for you. Another beneficial effect is keeping you awake and alert if you need to be on task, feel sleepy, or are sleep-deprived. Caffeine can keep a person awake to a certain point, but after that, they crash, making errors in judgment and nodding off to sleep without realizing it. Caffeine also enhances mood through feel-good dopamine reward pathways.

Straight out of the gate, we’re hitting you with something that’s not a true tea. Rooibos comes from the leaves of the Aspalathus linearis plant native to South Africa, where it is also considered the country’s national drink. Rooibos can stand in for breakfast tea, with a slightly earthy but sweet taste that won’t become bitter even with extended brewing.
Factors Affecting Caffeine Content
The type of tea leaf usedThere are a few factors that affect the levels of caffeine in your cup of tea. Generally, broken tea leaves, as found in tea bags, will impart more caffeine when brewed compared to whole leaves. Although matcha is a type of green tea, the difference in how it’s consumed warrants its own place on the list. Unlike most tea preparations, where the tea leaves are strained out, matcha is ground to such a fine powder that you end up with the whole lot in your cup. This pushes the amount of caffeine you’re consuming up a lot further than regular green tea. Matcha can contain anywhere from 19 to 44 mg per gram of powder, which is around half a level teaspoon.
Can caffeine content vary within the same tea type?
If you brew a delicate green tea with fully boiling water twisted tea recipe for a long time, its caffeine level can creep closer to that of a mild black tea. The caffeine in a cup of tea is not a fixed number on the box – it changes with how you brew. Steep time, water temperature, and how much leaf you use all influence the final caffeine level just as much as the tea type itself.
If you’re new to loose-leaf tea and want to experience the difference without the commitment, our Blueberry Bliss sample is the perfect introduction. It’s naturally caffeine-free, beginner-friendly, and comes with filters included—just add hot water. A single shot of espresso has about 127 mg of caffeine.
