What is Oolong Tea?

Oolong tea is a type of tea that originated in China and is known for its complex flavour profile and unique processing methods. This tea is produced in a variety of regions, including China, Taiwan, and India. However, the majority of oolong tea production occurs in China, where it has been produced for more than 400 years. It is a semi-oxidized and semi-fermented tea. That means this tea is somewhere between green tea and black tea in terms of processing. Oolong tea comes from the Camellia sinensis plant and is characterized by its partially oxidized leaves.

What Makes Oolong Tea Different?

The oxidation level of oolong tea can differ from 10–80%. This oxidation process is what determines the aroma and flavour of the tea. Ideally, oolong tea is considered to have a very complex and unique flavour. The flavour of oolong tea leaves can be grassy, woody, earthy, light, and sweet at the same time. But the proportion of each tasting note depends on the harvesting process. In terms of the harvesting process and oxidation level, oolong tea leaves are categorized into two categories.

Green Oolong Tea Leaves: Green oolongs are harvested in high-altitude areas from April to autumn. These tea leaves are oxidized up to 30–50%.

Dark Oolong Tea Leaves: Whereas, the harvest of dark oolong tea leaves starts from the end of spring. These tea leaves are oxidized up to 60–80%. For this reason, dark oolong tea leaves are mildly strong compared to green tea oolongs. Because of the texture, flavour, aroma, and of course the dark colour, earlier the tea used to be called "Black Dragon". 


How is Oolong Tea Made?

The mystery behind the dark flavour of oolong lies in the post-plucking manufacturing process. Let’s see what necessary processes oolong tea leaves undergo.

  • Withering: Raw tea leaves are very fragile and contain moisture. These tea leaves are tossed and kept under the sun to wither and lose moisture. After withering, the tea leaves are kept under shade so that the temperature gets reduced before oxidation.
  • Oxidation: Tea Oxidation is the process where the tea leaves are exposed to open air, or more precisely, to oxygen. This process will determine the types of tea leaves that are going to be formed. The more the tea leaf oxidizes, the stronger it becomes. For oolong tea, the oxidation process defines the colour and the aroma.
  • Final Rolling: Oolong tea leaf harvest needs the craftsmanship of the manufacturer. After oxidation, the tea leaves automatically start being rolled. But this natural rolling is not enough. Tea leaves need to be rolled properly so that they take on a shape.
  • Roasting: After rolling, tea leaves are left to dry for several hours. Then it is roasted at a low temperature to reduce the moisture completely. This roasting is important just before packaging. If oolong is packed, even with a little bit of moisture, it will lose its authenticity.

At the end of these manufacturing processes, the tea leaves finally become market-ready. Now it can be packaged to sell in the market.
