How to Choose Unroasted Oolong Tea

June 08, 2018

Here's a simple guide that defines and categorizes Taiwan's unroasted Oolong Tea in a way that will help you find your "cup of tea".

Alishan High Mountain Oolong Spring Harvest

What do the names mean?

The cryptic English spellings of the most famous tea names in Taiwan are one of the following:

  • A place name
  • A cultivar
  • A processing method

Place Name

The majority of unroasted Oolong Tea types fall under the first category of place names— Alishan High Mountain Oolong, Shan Lin Xi High Mountain Oolong, Li Shan High Mountain Oolong, Da Yu Ling High Mountain Oolong, and Wenshan Baozhong Tea.


Three popular names of Taiwan Tea fall under the second category of (hybrid) cultivar names— Jin Xuan Oolong, Tsui Yu Oolong, and Four Seasons Spring Oolong Tea.

Processing Method

Wenshan Baozhong Tea is the only one among our unroasted Oolong Teas that we need to distinguish by its processing method,

Place Names Representing Flavor Profiles Of High Mountain Teas

Place names represent geographic location and altitude. In Taiwan, the name High Mountain Tea classifies as any tea that is grown at 1000m elevation or higher.

Alishan is the southernmost High Mountain Tea producing region. This latitude offers both more direct and more abundant sunshine annually. The altitudes of the majority of tea farms in this region are 1000-1600m, with the highest farms at around 1600m.The climate conditions in this environment produce a milder, sweeter flavor profile with distinctly floral notes.

Heading north, Shan Lin Xi is the next High Mountain Tea producing region we reach. The geography and climate here are significantly different from the Alishan region. Tea gardens range from 1200-2000m elevation, and the environment has a much more "high alpine forest" feel. The steep forested slopes provide less sun, more fog, and cooler temperatures. This all adds up to producing a character of tea with a forest essence. It offers a tea with deep, green-leafy and pine notes, with a more full-flavored nutty character.


Continuing north, we reach the highest elevation tea growing region in Taiwan, which boasts the most renowned place names of Li Shan and Da Yu Ling  at altitudes above 2000m and geographically located in a mountain range with climate conditions that have proven to be the most ideal for High Mountain Oolong Tea production.

The produce from well managed tea gardens in this region, combined with skillful processing, makes the best unroasted High Mountain Oolong Tea available on the market. When minimally oxidized, the leaves offer a fresh green flavor profile with heady floral notes. Slightly more oxidation of the leaves result in a balanced, subtle fruity aroma with a rich, balanced profile that offers a purity of character that sets it apart. The substance of flavor and texture of high quality Lishan and Da Yu Ling High Mountain Tea are truly unsurpassed.

 Cultivars Representing Flavor Profiles

Jin Xuan / Tai Cha #12

Jin Xuan is often called "Milk Oolong" due to its distinctly buttery or milky notes in the flavor profile. It has a mild vegetal character with a smooth, buttery texture and aroma that makes it a friendly introduction to unroasted Oolong Tea.

Tsui Yu / Tai Cha #13

Tsui Yu literally means "blue/green jade", and is often translated as Jade Oolong. This hybrid cultivar is known for its distinct herbal/floral character and prominent aromatic qualities. It offers fresh, green, savory notes that set it apart from other strains of unroasted Oolong Tea. 

Four Season Spring

Four Season Spring is a naturally occurring hybrid that is now widely cultivated at lower elevations. It got its name due to the prolific year-round yield it produces. It has a distinctly bold floral character.

Processing Methods Representing Flavor Profiles

Wenshan Baozhong Tea is the only one of our unroasted Oolong Tea selections that is distinguished by its processing methods. And the most prominent aspect of processing that distinguishes the character of this tea is that it is not tightly rolled like all of the other types mentioned above. There is something about maintaining the natural integrity in the leaf by only gently curling the leaves as they are dried that offers a deep green vegetal quality with a well-rounded complex character that is unmatched.

This is what has kept Baozhong Tea in demand and alive in Taiwan's modern tea industry. It offers a fresh vegetal character with substance and balance, followed by a heady lingering aftertaste. It really does stand alone in the unroasted Oolong Tea category. Baozhong Tea is produced in the northernmost tea growing region, above Taipei, in the Wenshan/Pinglin mountainous area. This north-island environment offers plentiful rainfall, at altitudes of 500-800m.
