About Benefits of Oolong Tea
A lot has changed since tea was discovered by chance by a Chinese emperor, Shen Nung. Initially, it was used only for medicinal purposes; then, by the late 17th century, tea had become the regular beverage of the elite. (Benefits of Oolong Tea)
But today, not only black teas, but also some other teas with much more health benefits are popular. One such tea is Oolong tea, which is said to be very healthy. So, let’s take a deep dive into what this Oolong tea is and what magical benefits it has. (Benefits of Oolong Tea)
What is Oolong Tea?
It is a semi-oxidized Chinese tea that has gone through a unique process, including withering in direct sun and then partially oxidizing the leaves. This is why oolong tea is also called semi-fermented tea.
Oolong tea originated in the Chinese province of Fujian, but is now widely produced in Taiwan as well. It is still processed according to three centuries old traditions. (Benefits of Oolong Tea)
Basic Steps in Oolong Tea Making
The processing of oolong tea is described in the following easy steps.
Harvesting
The tea leaves for oolong tea are typically harvested 3-4 times a year, with some farms even having the possibility of 6 harvests.
Withering
Thanks to the enzymes that initiate a chemical reaction in the leaves, the leaves begin to wilt after the harvest. It is up to the tea grower how to control this withering process to achieve the desired taste of oolong tea.
Oxidation
Chemically speaking, in this step the cell walls of the tea leaves are broken. That is, leaves are exposed to air or other methods where they can be oxidized.
It is normally made by putting leaves on long woven bamboo cylinders
Kill-Green Step
This is the control step where oxidation is stopped when the desired oxidation level is reached.
Kill Green is the translation of the Chinese term ‘Shaqing’ which means to kill the green.Rolling and Drying
Finally, when the Kill Green process is finished, the Rolling and Drying process begins. The oxidized leaves are wrapped with the help of modern machines and left to dry. (Benefits of Oolong Tea)

Caffeine | (mg/8 ounces) | 10-60 | 9-63 | 42-79 |
Flavonoids: | 49.4 | 125.6 | 25.4 | |
Epicatechin- EC | (mg/100ml) | 2.5 | 8.3 | 2.1 |
Epicatechin Gallate – ECG | (mg/100ml) | 6.3 | 17.9 | 5.9 |
Epigallocatechin – EGC | (mg/100ml) | 6.1 | 29.2 | 8.0 |
Epigallocatechin Gallate – EGCG | (mg/100ml) | 34.5 | 70.2 | 9.4 |

Types of Oolong Tea
There are two main types of Oolong tea, depending on the processing method you follow. One is slightly oxidized, undergoing oxidation of 10% to 30%, giving it a bright green, floral and buttery appearance.
Dark oolong tea, on the other hand, is oxidized up to 50-70% to look more like black tea. (Benefits of Oolong Tea)

Are Oolong and Green Tea the same? (Oolong and Green Tea)
Most people think so, but they are not the same. Both teas are derived from the same plant, Camellia sinensis, but the difference still lies.
The difference is the processing methods of the two. Green tea is not fermented whereas oolong tea is semi-fermented. (Benefits of Oolong Tea)
Green tea involves using young tea leaves that do not go through any fermentation process after withering. Here, the pan-cooking method is used to prevent it from fermenting.

Black tea is called fermented tea. The leaves are allowed to ferment for several hours before being steamed, flame-lit, or smoke-ignited.
In the first step of processing black tea, the first tea cloves are exposed to air to oxidize. As a result, the leaves turn brown and the flavor intensifies and is then heated or left as is.
Oolong tea, on the other hand, is semi-oxidized, meaning they are much less exposed to air than black tea.
In terms of chemistry, black tea leaves are completely crushed to maximize the reaction between catechin and polyphenol oxidase.
They are low in monomeric flavins and rich in Thearubigins and Theaflavins, as they are allowed to oxidize before they are completely dried. Theaflavins are known to have higher antioxidant capacity than others. (Benefits of Oolong Tea)
