Caffeine content in tea
Caffeine Content in Tea
Tea contains caffeine – but not in the way many people think. Compared to coffee, its effect is gentler, more even, and often longer-lasting. Here you can find out why this is the case and how much caffeine different teas contain.
Does tea really contain caffeine?
Yes. The tea plant (Camellia sinensis) naturally contains caffeine. Previously, it was referred to as "theine." Chemically, however, it is identical to the caffeine in coffee. The difference lies not in the substance itself, but in its effect in combination with the other ingredients of the tea.
Why does tea affect you differently than coffee?
In addition to caffeine, tea also contains tannins and amino acids like L-theanine. This combination ensures that caffeine is released more slowly. The effect is gentler, lasts longer, and is often perceived as clearer and more balanced. While coffee often creates a quick "peak," tea has a more even effect.
How much caffeine is in each type of tea?
The caffeine content depends on several factors: tea variety, leaf grade, brewing time, and water temperature.
Green Tea
Green tea has a moderate caffeine content and is stimulating, but usually harmonious and clear.
Black Tea
Black tea generally has more caffeine and is often perceived as stronger and more invigorating.
Oolong
Oolong, depending on the degree of oxidation, falls between green and black tea and accordingly shows variable values.
White Tea
White tea is often underestimated. It can also contain a noticeable amount of caffeine, especially if young buds were processed.
Matcha
Matcha contains comparatively a lot of caffeine, as the entire leaf is consumed when drinking it. The effect is intense, but at the same time calm and focused due to L-theanine.
Herbal and Fruit Teas
These teas are naturally caffeine-free and are ideal for the evening or for sensitive individuals.
Does brewing time affect caffeine content?
Caffeine dissolves relatively quickly in water. However, a longer brewing time also increases the proportion of tannins, which balance the effect. A tea brewed for longer, therefore, does not necessarily have a stronger effect, but often a more astringent and even one.
Which tea is suitable for the evening?
For the evening, herbal or fruit teas, decaffeinated varieties, or mildly infused green teas with a short brewing time are recommended. Those who are sensitive to caffeine should specifically opt for caffeine-free blends.
Conclusion
Tea contains caffeine – but its effect is more complex than that of coffee. The combination with natural plant compounds creates a balanced sense of alertness that many find more pleasant. If you are specifically looking for an invigorating or a mild tea, you will find a large selection of green, black, and herbal teas with us – suitable for any time of day.
