1. What is black tea?
Black tea is a caffeinated drink made from the leaves of the Camellia sinensis tea plant. It is traditionally drunk around the world and known for its earthy, bitter taste and varied aromas.
Black tea also contains important active compounds, vitamins and minerals that contribute to health. It naturally contains caffeine, though considerably less than Guayusa, coffee or mate. For a detailed comparison, see our article “Guayusa and mate tea caffeine content compared”

| Type | Caffeine |
|---|---|
| Guayusa | 3%–7.6% |
| Coffee | 1.4%–3.2% |
| Yerba mate | 1.4% |
| Tea | 1.2% |
2. Caffeine in black tea
Black tea contains less caffeine than Guayusa tea or coffee, for example. A 2017 study reports an average of 32 mg of caffeine per cup of black tea (237 ml). By comparison, a cup of Guayusa contains about 80–95 mg.
Caffeine levels in black tea vary by variety, processing and preparation. Teas fermented for a long time may contain more caffeine than less-fermented teas. Milk or cream can reduce the caffeine content because caffeine is water-soluble, not fat-soluble.

3. Benefits of black tea
Its intensely bitter taste makes black tea appealing to people who also enjoy coffee. Bitter compounds promote circulation and digestion, strengthen the immune system, and stimulate fat metabolism in the liver and gallbladder.
4. Downsides of black tea
Black tea’s bitter taste can be a drawback for people who prefer milder teas such as Guayusa. Its caffeine content is much lower than commonly believed.
Black tea stains teeth yellow because of its tannins, just like coffee. If you want to keep your teeth white, drink black tea in moderation.
Another downside is the environmental footprint of growing black tea, which is poor because even organic black tea is grown only in monocultures. Read our detailed article on cultivation methods here.
5. Conclusion
Black tea contains caffeine, like green tea, coffee and Guayusa, but may not be the best pick-me-up because its caffeine content is too low. Guayusa tea is a better option: it contains more caffeine than both black tea and coffee. To learn more about Guayusa’s effects, read our article “Guayusa tea: effects and what you need to know”
