Oolong tea is a type of tea made from the Camellia sinensis plant where the tea leaves are withered and oxidized by sunlight, which causes them to twist or curl.
The Chinese word for Oolong tea means "black dragon tea" and it comes in 2 different styles.
The Journal of Food Science recently tested several varieties of Oolong tea and they discovered varying levels of caffeine.
|Oolong Tea Brand||Size (fl.oz. using 2g tea)||Caffeine|
|Pu-erh Oolong (Stash)||8||41.6mg|
|Tea Ren Oolong||8||16.6mg|
|China Oolong (Stash)||8||33.4mg|
|Exotica Champagne Oolong (Stash)||8||55.4mg|
Depending on the brand/variety chosen, Oolong tea can range from just 16.6mg/cup to 55.4mg/cup. We took the average of the 4 types listed above and used this number as our caffeine content listing.
Oolong tea became more popular a few years ago since it was promoted as a weight loss beverage. However, this hasn't been proven and is likely no better for weight loss than drinking green or black tea.
