Oolong Tea: Health Benefits, History, Nutrition Facts

Etymologically speaking, Oolong tea derives its name from two words, meaning “black” and “dragon” – a reference to the shape and color of the tea leaves. This semi-oxidized tea offers a perfect middle ground between the fully oxidized black tea and the barely oxidized green tea. Hence, this tea is excellent for those who do not like the strong bitter taste of black tea but don’t fancy the grassy notes of green tea either. Depending on the degree to which the tea leaves are oxidized (8—85 %), this tea is available in various flavor textures – from the lighter, more floral green variants to the deeper, more woody blacker teas.

The processing of the tea – right from picking to rolling – is integral to the flavor of Oolong. Shortly after the tea leaves are picked, they are withered and partially oxidized by keeping them out in the sun and then in the shade. After that, the tea leaves are basket-tossed to break down the cells on the surface of the leaves. The natural oxidation process is halted by roasting the leaves in a wok, either over charcoal or wood, which adds to the unique flavor of the tea. Finally, the leaves are curled or rolled into tight balls or thin strands. The rolling of the tea leaves is a crucial step, which defines the final flavor of the tea.

History of Oolong Tea

Three widely accepted theories explain the origin of Oolong tea.

If the “tribute tea” theory is believed, this tea was discovered in China’s Fujian province during the reign of the Tang dynasty. The tea’s predecessor, Beiyuan tea, was served to the emperor after being compressed into cakes, as was the tradition then. This tribute was then known as the Dragon-Phoenix cake after the two different types of tea found in the cake. Later, when the tea became popularised in its loose form, its name was changed to “black dragon” tea or oolong tea.

The second theory assigns the origin of Oolong to the Wuyi mountain region, with the tea named after the part of the Wuyi mountain where it was produced. This theory is supported by poems written during the Qing dynasty – the first instance of documentation recorded in Oolong’s history.

The third theory, which is the most famous legend, says that the tea was discovered by accident during the reign of the Qing dynasty in the province of Fujian. According to the legend, a tea farmer was picking tea one day when he got distracted by a deer that he set out to hunt. He only got back to the plucked leaves the next day, by which time the tea leaves had already started to oxidize. The result was a completely new flavor that was strong and sweet but without any bitterness. This tea farmer’s nickname was Oolong, after which the tea was named.

In the early 1800s, a Fujian tea merchant carried some Oolong seeds to Taiwan, which led to widespread tea production in that region. However, it was not before 1868, when John Dodd set up tea processing units in Taipai, that this tea began getting exported worldwide from Taiwan. Now, the cultivation of Oolong has spread to various parts of Asia, including even Indian and Nepal. However, the best oolong tea still comes from the Anxi or Fujian regions of China or Taiwan.

How to Prepare a cup of Oolong

Since the oxidation level of Oolong varies depending upon the type of tea, the quantity, brewing temperature, and steeping time are different for different variants. Hence, it is a good idea to request the vendor for specific brewing instructions. However, generally, Oolongs can be steeped at temperatures ranging anywhere between 180°F to 190°F, i.e., before the water reaches boiling point. And as a general rule of thumb, 1 teaspoon of rolled Oolongs and 1 tablespoon of longleaf Oolong can be used for 240 ml of water.

It is recommended to steep Oolong tea multiple times, for each steeping unfurls the leaves further, unlocking more decadent flavors. The same tea leaves can be steeped 3—5 times, offering a different flavor profile each time. When brewing Oolong, be careful not to over-steep the tea. The ideal steeping time is anywhere between 1 minute to 3. You can taste your brewed cup after a minute of steeping and check how much more you’d like to steep the tea, if at all. To get the best flavors out of this tea, brew your Oolong in a ceramic or clay vessel.

The Best way to Consume Oolong

The subtleties and different shades of Oolong’s flavor can be best enjoyed without any additives, such as milk or sweetening agents. However, the darker variants might require some sweetening for those who like the bitterness of their tea diluted. If you belong to this lot of tea-drinkers, please add some honey or sugar to your tea. However, adding milk runs the risk of taking away from this tea its interesting, complex flavors. This tea should be consumed black.
