Chinese oolong tea does contain a certain amount of caffeine. Oolong tea is a variety of semi-fermented tea within the green tea category. It undergoes a complex process, including harvesting, withering, shaking, oxidizing, fixing, rolling, and baking, to create a distinct tea profile.
Oolong tea contains a moderate amount of caffeine and theanine, which, when consumed, stimulates the cerebral cortex, helping maintain fluid regulation in the central nervous system. As a result, it has a moderate fatigue-relieving effect on the body. Apart from oolong tea, common types of green tea, black tea, yellow tea, and white peony tea also contain some caffeine.
When it comes to choosing between oolong tea and coffee for a pick-me-up, it depends on the circumstances. Oolong tea typically contains about 2%-5% caffeine, which dissolves in water when brewed. Therefore, a regular 200 milliliter cup of oolong tea contains approximately 12-18 milligrams of caffeine. In contrast, a cup of coffee can have caffeine concentrations ranging from 20 milligrams to around 200 milligrams, depending on the coffee type.
In summary, oolong tea generally has lower caffeine content compared to coffee. However, because oolong tea also contains theanine, catechins, and other alertness-promoting compounds, the choice between oolong tea and coffee for a pick-me-up depends on various factors and personal preferences.
