What is Oolong Tea?
Oolong tea is a type of tea that is partially oxidized, sitting somewhere between green and black tea. Also known as “Wulong,” oolong tea means “black dragon” in Chinese. This name comes from the dark-colored and curled appearance of the tea leaves. Depending on the level of oxidation, oolong tea can be light (close to green tea) or dark (close to black tea), which determines the tea's characteristic features.
Oolong tea is primarily produced in China and Taiwan, with both regions having developed their own unique varieties of oolong. Chinese oolongs are generally lighter and more floral, while Taiwanese oolongs have a creamier and fruitier profile. This type of tea holds a special place among tea enthusiasts due to its complex aroma and rich flavor.
The History of Oolong Tea
The origin of oolong tea dates back to the 16th century in Fujian province, China. According to legend, a tea producer was disturbed by a deer after picking the tea leaves and forgot to process the leaves. The next day, he noticed that the leaves had partially oxidized and discovered this new type of tea. This story describes the accidental discovery of oolong tea.
Oolong tea gained popularity during the Qing Dynasty (1644-1912). During this period, Chinese emperors particularly favored oolong tea, and this type of tea held a special place in the palace. In the 19th century, oolong tea was brought to Taiwan, where it developed its own characteristic features. Today, both China and Taiwan produce some of the world's highest quality oolong teas.
The Production Process of Oolong Tea
The production of Oolong tea is a combination of green and black tea production. The first stage is the harvesting of tea leaves. For Oolong, more mature leaves are generally preferred. The harvested leaves undergo a withering process. At this stage, the moisture content of the leaves is reduced, and they gain flexibility.
After the withering process, the leaves are crushed or rolled. This process breaks down the cell walls, allowing enzymes to be released. Then, a controlled oxidation process begins. The uniqueness of Oolong tea comes from the control of this oxidation process. When the producer reaches the desired level of oxidation, they stop the oxidation by roasting the leaves at a high temperature.
The oxidation level determines the character of oolong tea. Lightly oxidized oolongs (10-30%) have a profile close to green tea and possess a floral, fresh aroma. Medium oxidized oolongs (30-50%) have a balanced profile. Darkly oxidized oolongs (50-70%) have a profile close to black tea and feature a roasted, earthy aroma.
Health Benefits of Oolong Tea
Oolong tea combines the health benefits of both green and black tea. Thanks to its high polyphenol content, it has strong antioxidant properties. These antioxidants fight free radicals in the body and prevent cell damage.
Regular consumption of oolong tea may assist with weight management. Research shows that oolong tea accelerates metabolism and increases fat burning. Additionally, it is known that oolong tea reduces feelings of hunger and boosts energy levels.
Oolong tea also supports heart health. Regular consumption lowers bad cholesterol (LDL) levels and increases good cholesterol (HDL) levels. Additionally, it is known that oolong tea regulates blood pressure and reduces the risk of heart attack.
Oolong tea can also improve dental health. Thanks to its fluoride content, it prevents tooth decay and strengthens tooth enamel. Additionally, oolong tea is known to reduce bad breath.

How to Brew Oolong Tea?
For a perfect cup of oolong tea, the right temperature and brewing time are very important. Oolong tea should be brewed at different temperatures according to its oxidation level. The ideal temperatures are 80-85°C for lightly oxidized oolongs, 85-90°C for moderately oxidized oolongs, and 90-95°C for darkly oxidized oolongs.
Brewing time varies depending on the type of tea. Generally, 3-5 minutes is sufficient. Oolong tea can also be brewed using the multiple infusion (gongfu cha) method. In this method, a small amount of tea is used and brewed multiple times for short intervals (30 seconds – 2 minutes). Different flavors emerge with each infusion.
Oolong tea is usually consumed on its own. Due to its complex aroma and rich flavor, it does not require any additional sweeteners. However, if desired, a light sweetener can be added. A quality oolong tea already has its own unique taste and does not need any extra ingredients.
