How Much Caffeine Is in Green Tea?

Green tea typically contains less caffeine than coffee, but the exact amount can vary depending on the type of tea and how it is brewed.

One 8-ounce (240ml) cup of green tea contains about 25-40mg of caffeine, while the same serving of coffee contains around 100-120mg of caffeine.

The caffeine content of green tea can also be affected by several other factors, such as:

- The type of green tea leaves used (some varieties, like matcha, contain more caffeine than others).

- The temperature of the water used for brewing (hotter water extracts more caffeine).

- The steeping time (longer steeping times result in higher caffeine levels).

It's worth noting that the amount of caffeine in green tea can also vary between brands and individual plants, so the actual content may differ from the averages mentioned above.
