Is oolong tea caffeinated？

Yes, oolong tea is caffeinated. Oolong is a traditional Chinese tea that falls somewhere between green and black tea in oxidation. Although the exact caffeine content can vary depending on the specific oolong tea blend and how it’s prepared, it generally contains less caffeine than black tea but more than green tea.

On average, an 8-ounce (about 240 milliliters) cup of oolong tea contains between 30 and 60 mg of caffeine. This is less than the average cup of coffee but enough to have a noticeable stimulant effect for most people.

As with green tea, factors such as the quality of the tea, how the leaves are processed, steeping time, water temperature, and the amount of tea used will affect the caffeine content. To control the amount of caffeine you consume from oolong tea, you can adjust these variables when brewing your cup.
