Types of Oolong Tea

The majority of the oolong tea types belong to the most treasured teas in the world. Their quality depends to a large extent on the person making it, as well as the amount of care taken during the cultivation process. A simple mistake in the production methods may create an unpleasant aroma that can directly affect its taste.

How is Oolong tea made

When oolong is correctly produced, however, the result is a tea that improves with each steep in a way that green or black tea never can. A good quality oolong tea can be steeped many times and may produce a different, more pleasurable taste experience with each brew. Try this with English breakfast tea, and all you’ll end up with is brown water…

Oolong Is All About the Oxidation

Oolongs are sometimes known as ‘partially oxidized’ teas, and it’s easy to understand why. Oxidation begins the moment the tea is picked. A prolonged oxidation process produces a malty black tea with high levels of acidity. Depending on the type of oolong, the qualities and bright to dark green physical appearance is preserved by interrupting oxidation at exactly the right time. This interruption is caused by heating the oolong leaves at precisely the right stage of the cultivation method. Technically speaking, the term ‘oolong’ can be applied to any tea whose oxidation falls between 8-80%.

Oxidation and caffeine difference between teas

Timing is crucial, but it’s not the only critical factor in oolong production. Oolong cultivation comprises methods and guidelines which must be strictly followed. It all depends from the amount of time the leaves are withered to the way they are mixed, blended, rolled and pressed. All at specific humidity levels and temperatures. These processes take place before the final roasting, after which most teas are considered fit to drink.

Oolong Tea Production

The cultivation of oolong tea is a process handed down over the centuries, and much depends on the skill and knowledge of traditional oolong farmers. As you can imagine, production takes a number of days, and involves as many as a dozen different phases.

Oolong tea production process

The water in the leaves must be vaporized to the correct levels. The tea must be precisely pressed and bruised to allow the leaves to develop the desired taste and aroma. By looking at the leaves, smelling, feeling, and touching them, expert oolong farmers know exactly which ingredients their teas require.

On the other hand, modern oolong producers are not above making use of substantial machines and state-of-the-art thermoregulation instruments to guarantee a reliable, quality, beneficial and delicious product.

As an integral part of their culture, China and Taiwan are well-known as the main producers of oolong teas. However, the teas from these two very countries differ in many ways. Each has its own unique taste, texture, and leaf shape.

China Oolong Teas

Fujian

In Fujian, the production of tea mainly takes place in two regions: Anxi county and the Wuyi Mountains. These areas are both major centers for the production of oolong tea in China.

Wuyi Mountains

This is where the most expensive and exotic oolong teas are produced. Labeled as ‘famous Chinese teas’ or Si-da Ming Cong Teas, they are one of the most famous Wuyi Oolong teas. The location is also accredited for its traditional, organic production methods. Here are some well-known cliff teas:

  • Da Hong Pao is a prized tea, as well as Si Da Ming Cong tea.
  • Shui Jin Gui is also referred to as “Golden Water Turtle”: it is a Si Da Ming Cong tea.

Dancong was originally the term used when people referred to Phoenix teas that were all picked from the same tree. More recently, however, it has become the term used for all of the Phoenix mountain oolong teas. Authentic dancongs, while still produced, are no longer common outside of China.

Different Oolong Tea types

Taiwan Oolong Tea

In the 18th century, the cultivation of tea began in Taiwan. Nowadays, many of the Fujian grown teas are also cultivated in Taiwan. Since the 1970s Taiwan’s tea industry has advanced rapidly to keep in step with the rest of its economy. Since Taiwan has such a tea-loving culture, plus a very high domestic demand, most of their tea production is bought and consumed by its own population.

Because the weather in Taiwan is very unpredictable, the quality of their tea can vary with each season. Taiwan is not a very large island, and it has many geographic variations. Frequent mountains tower above very low coastal plains. The varying weather, temperatures, and differences in soil per region lead to a huge amount of aromas and flavors of Taiwan tea. Varieties that grow in very highly elevated areas are known to produce a unique, sweet tea that carries quite a hefty price tag.

  • Dongding (“Ice Peak/ Frozen Summit”): Named in honor of the Nantou County mountain. Cultivated in the central part of Taiwan this tea is snuggly rolled and produces an unforgettable aroma.
  • Oriental Beauty Oolong tea

Grown at elevations of 1,000 to 1,400 meters the tea has only a small time frame to benefit from strong sunlight. This results in a less astringent, yet sweeter brew. The tea is daffodil yellow with fruity notes.
  • High Mountian (Gao Shan) oolong teas: Being grown close to the Lishan mountain in north-central Taiwan, this brew is quite similar in looks to Alishan teas. It grows at elevations above 1,000 meters. Lishan, Fusou, and Dayuling are the most widely known regions for the teas of Lishan. The tea is frequently grown on the obscure Taiwanese Mango, a relative of the tropical mango tree. The thin branches provide excellent exposure to the sun and offer excellent support for the vines of the tea plant.
  • Pouchong: This the most floral and lightest of oolongs, with leaves of a pale green to brownish hue when unrolled. Although grown in Fujian originally, today it is widely produced near Taipei, in the Pinglin Township.
  • Jin Xuan - Milk Oolong tea

    Jin Xuan: A group of oolong teas created in 1980. Also called “Milk Oolong,” this tea is known for its smooth, frothy, and easy to drink texture and taste. However, traditional milk oolong doesn’t contain any dairy products and originates from Taiwan.

  • Tieguanyin: Muzha Tea Co. transported tea from Anxi County, developing Taiwan’s own innovation of the tea. It is now grown on the hills of Muzha area close to Taipei. With more than a century of cultivation, the tea has developed a unique flavor all of its own.

Vietnamese Oolong Tea

For centuries, tea has played a significant role in the Vietnamese culture. And its no wonder. The climate in Vietnam is ideal for cultivating tea, and the country has excelled as a producer for both domestic and international consumption. In fact, if it hadn’t been for Vietnam’s tragic history of armed conflict, the country would today be one of the major tea produces in the world.

Thankfully, this situation has now changed, and Vietnam is well on its way to becoming a major player in the global tea industry.

Vietnamese Imperial oolong tea

Imperial oolong tea

As with other oolong tea types, the Vietnamese oolong uses the larger leaves of the plant, unlike other teas that focus solely on the bud. Vietnamese oolong traditionally relies on its century-old craftsmanship to create a host of high-quality teas. One of the most famous Vietnamese oolongs is the curly-leafed, dark green Imperial variant. Once infused, this tea turns light green, a tell-tale sign of low oxidation levels, and produces a tea with the soft and sweet nuances of honey.

Other Oolong Tea Types

Other notable varieties include:

  • Darjeeling oolong: An Indian tea grown according to Chinese techniques.
  • Assam smoked oolong: This tea is smoked over open flames, and also made following Chinese methods.
  • Zealong: Grown not far from Hamilton, New Zealand.

Such is the enormous diversity of oolong, the tea is not only sorted into different types, but also into different categories. Some of the most notable groupings of oolong tea include monkey picked and milk oolong tea.

Monkey Picked

The most popular money picked tea is the Tie Guan Yin which is also among the rarest oolongs in the world. Discovered in the 18th century in Fujian province, monkey picked derives its name from a folk tale which claims that monkeys, native to the mountainous region were trained by local monks to pick the tea from the highest branches.

The term later evolved to mean tea of the very highest quality, as in Tie Guan Yin. Monkey picked teas are considered to be among the most authentic oolong teas. It is still produced on a small scale and is prepared by traditional family tea handlers.

Milk Oolong

The title ‘milk oolong’ comes from the tea’s floral aroma and its milky sweet taste. It should not be confused with intentionally adding milk into your tea. Milk oolong has gained popularity as one of the most delicious oolong teas thanks to its light yet flavorful taste. One of the most famous tea in this category is the Jin Xuan.

Milk (Jinxuan) Oolong Tea brewed

The oxidation process of milk oolong twists the leaves and gives them the dark green/brown color. Once the tea master is satisfied with the level of oxidation, the leaves are heated to stop the oxidation. This process is repeated a number of times until the desired result is reached.

It should come as no surprise that the best oolongs are grown in harsh, mountainous regions. The location of the plant plays a crucial role in the nutritional facts, producing the unique of flavor the tea acquires after oxidation. The best creamy teas benefit from the environmental conditions of their surroundings to fully develop their aromas and flavors.
