Red Jade Black Tea: Taiwan's Black Tea Specialty

April 03, 2019

What is called "red tea" (紅茶 / 红茶) in Chinese is known as Black Tea in English. Taiwan has its own special Black Tea named Red Jade Black Tea due to its luminescent reddish-ochre brew. Also known as Taiwan Tea No. 18, Red Jade Black Tea is a hybrid of the Assam tea plant and the wild tea tree that grows naturally in the mountain forests of Taiwan.

Hybrid Creation

This strain of tea was created by the government subsidized Tea Research Extension Station in the Sun Moon Lake tea growing region of Nantou County. Since it possesses the DNA of a wild plant in the local eco-system, it has natural immunity to some of the “pests” that tend to compromise the health of the more conventionally cultivated tea plants. Consequently, this tea type can be cultivated without the use of any chemical fertilizers or pesticides. Our source uses no chemical products in his farming methods.

Special Type of Black Tea

These wild tea qualities, in combination with the Assam tea plant that was originally a native plant to South and Southeast Asia produces an extraordinary type of Black Tea. The processing of Black Tea involves full oxidation of the leaves after being harvested, followed by low-temperature drying without any roasting. Unlike the production Taiwan Oolong Teas, Black Tea is processed without being exposed to high temperatures to cease oxidation or subsequent roasting. Because of this, it maintains more of its natural character – similar to that of dried fruit or nuts. Summer is considered to be the prime harvest time for Black Tea, when the leaves contain the most catechins, providing more flavor and astringency. However, some prominent Black Tea makers are of the conviction that spring harvest makes the most complex flavor profile in the brewed tea.

Family-Run Production

This batch of tea was harvested from a farm that has been managed by a local farmer for well over a decade. In recent years however, our friend who is an organic tea farmer has contracted this farm to cultivate its crop naturally, using no chemical farm products whatsoever. Our friend began with a commitment to procure 1/3 of the seasonal crop, and in less than 3 years has increased his procurement to 2/3, based on demand for his naturally cultivated Red Jade Tea that he processes himself in his home factory. He has had these leaves tested annually with consistent ND results, which indicates zero chemicals in the tea leaves. This new generation with an integrated sustainable approach to tea production is the kind of development in the industry we seek to support.

Our friend lives in the Songbolin tea producing region, and his home factory is equipped for Black Tea processing, which was used by previous generations in his family, but was dormant for many years before this new development. He has repurposed his inherited factory for the production of naturally cultivated Black Tea from a nearby region. He processes his Black Tea himself, using his own factory, which reduces cost and allows him to market it at competitive prices. This also is the kind of sustainable business approach that we are committed to supporting in the local industry. 

How to Brew

These leaves are best brewed with slightly below boiling temperature water and with a conservative amount of tea leaves, although the unrolled tea leaves make it look like more in volume than its tightly rolled Oolong cousins. Quick, repeated steepings are ideal for this tea type for maximum fragrance and minimum astringency.

These leaves were harvested by hand from the residential farm that is our ongoing source of Dong Ding Oolong Tea. They were also de-stemmed by hand and roasted extensively to meet the competition standard. The brewed tea has a bold roasted character that is balanced out by a rich, smooth textured and complex flavor profile. It is reminiscent of fire-roasted yams and butternut squash.

This month's edition of the Eco-Cha Tea Club is from the same day's harvest of spring tea that our source received the Top 2% Award out of 750 odd participants in the spring 2019 competition. This month's batch of tea was prepared the same way as the award winning tea — removing the stems by hand and undergoing repeated roastings to meet the standard of quality set by this local competition. Only residents of this small community of traditional tea makers are eligible to enter this competition. But this is the heart of Dong Ding Oolong Country, and this community boasts the densest population of traditional Oolong Tea artisans in Taiwan, and probably in the world!

The complex aroma of the brewed tea leaves has subtle hints of a bug bitten character, but not very obvious. The sufficient oxidation offers a fresh scone scent, with a touch of honey, making us think that there is some influence from the Green Leafhopper. It is very likely that this note is subtle due to the fact that it had rained very near harvest time, which is said to dilute or dissipate the chemical compounds that are responsible for this character of flavor. The texture is smooth and balanced, with delicate complexity.
