Oolong Tea: Origins and facts

Oolong tea is a different variety of tea that does not fall in the category of green or black tea. While black tea is fully oxidized and green tea is barely oxidized in processing, Oolong is a partially oxidized tea. The traditional process by tea masters in the making of this tea undergoes twisting and rolling to thin strands or balls. During rolling or processing the appearance of the tea changes its aroma and color. The final flavor of the tea also depends on the processing technique done by the artisan or tea master.

China and Taiwan are the countries of origin for Oolong tea, and it is highly popular in these countries. As per old stories, Oolong tea is said to be discovered by a farmer Wu Liang by accident which started to oxidize in the evening after picking them up the whole day. The best quality and most popular Oolongs are grown in the cool weather of the mountainous region. The rocky terrains and harsh environment are suitable for the tea to grow and attain a rich flavor. Oolongs grown in Taiwan are 10-40% less oxidized and green in color. These are also comparatively lighter than Chinese Oolongs. The other countries that are growing Oolong are India, Thailand, New Zealand, Sri Lanka, and Japan.

Tea processing is a traditional skill of the tea masters which needs a serious understanding. Camellia Sinensis is the plant that is the source of Green, Black and Oolong varieties. The processing plays a crucial and main role with the other factors like the terroir or type of the tea plant and geography or culture.

The main steps involved in Oolong Tea processing are as below:

  • The fresh leaves picked are shaken or tossed so that they are bruised, and oxidation is initiated.

The flavor depends a lot on the oxidation process. Now the leaves are spread under the sun to dry and wither. This makes the tea supple and soft and does not break during rolling or shaping.

  • The length of the oxidization process and the chemical reaction determines the color and the final appearance of the tea. Oxidation varies from 8-80% and it determines the kind or type of tea after processing.
  • Now the leaves are left to dry. Drying the leaves is important to reduce the moisture. When the moisture is reduced, it can be easily stored.
  • The sun-dried leaves are cooled and left to rest. This flattens the leaves which are good for rolling.
  • Now to halt the oxidation process, heat is applied for roasting. Roasting adds character and flavor to the final tea.
  • The dried tea is now sorted into separate groups of color and variety. It is segregated and separated into different grades and varieties as per their properties or flavor.

  • Next is the rolling process of leaves. Rolling makes them bruise and release oils and enzymes which again exposes them to oxidation. Rolling gives a shape to the leaves as well.
  • The final shape of Oolong tea is defined by shape. The partially dried leaves are again rolled for final flavor and appearance or results.
