【Green Jade Oolong】Taiwanese Tea No. 13


There are many different varieties of tea trees. We often hear about Sijichun, Jinxuan, Yingxiang, and Jade, which we will introduce today. Different tea trees undergo different degrees of roasting to make black tea, green tea and oolong tea. Among them, oolong tea is one of the representative baked teas in Taiwan.

Green Jade Oolong is the No. 13 Taiwanese tea, an improved variety officially announced by the Taiwan Council of Agriculture. Jade tea tree varieties are most suitable for making Baozhong tea and lightly fermented oolong tea. The most distinctive feature of oolong tea made from the Jade tea tree species is the rich aroma of wild ginger and sweet-scented osmanthus. Because of its special aroma, it is a popular option for many tea drinkers who like the taste of green tea. Jade Oolong is highly recommended for beginners who have not been in touch with tea as the delicate and elegant taste is a tea aroma that everyone can accept.


What is Green Jade Oolong?

Why is it called Green Jade Oolong and where does the name originate?

In 1945, the Japanese left more than 500 tea tree saplings, and after more than 30 years of research, breeding, improvements and innovation, a brand new variety evolved. The Agriculture Committee came to the decision after many discussions, that a code name was incompatible with the artistic flavour of this tea tree. Finally, Mr. Wu Zhenduo, a senior employee of Tea Research and Extension Station, Council of Agriculture, Executive Yuan, who is also the “Father of Taiwan Tea”, used his mother’s name “Jade” to name Taiwanese Tea No. 13. With such an elegant naming method, it is no wonder that Jade instantly became popular, and has been able to retain such a loyal customer base. The official system code of Taiwanese No. 13 is 2029, so Jade Oolong is also known as “Erjiuzai (29zai)”.
