How Much Caffeine Is in Tea?

The amount of caffeine in tea can vary depending on the type of tea, how it is processed, and how long it is brewed. In general, tea contains less caffeine than coffee, making it a popular choice for a gentler lift.

Average Caffeine Levels

Black tea: 40–70mg per cup
Green tea: 20–45mg per cup
White tea: 15–30mg per cup
Oolong tea: 30–50mg per cup
Herbal tea: 0mg (naturally caffeine-free)

What Affects Caffeine Levels?

Several factors influence how much caffeine ends up in your cup. These include the type of tea leaf, how finely it is cut, the water temperature, and the brewing time. Longer steeping times generally result in higher caffeine levels.

Loose Leaf vs Teabags

Loose leaf tea often contains whole or larger leaves, which release caffeine more gradually. Finer-cut tea in teabags can release caffeine more quickly, leading to a stronger initial infusion.

Reducing Caffeine in Tea

If you prefer a lower caffeine cup, you can shorten the steeping time slightly or choose teas naturally lower in caffeine, such as white or green tea. Herbal infusions are naturally caffeine-free.

Does Tea Give a Different Effect to Coffee?

Tea contains caffeine along with other natural compounds, which can provide a smoother, more balanced lift compared to coffee. Many people find tea less likely to cause the sharp peaks and drops sometimes associated with coffee.
