Oolong tea is often regarded as one of the most complex and captivating tea varieties in the world. With a rich history, diverse flavors, and intricate processing techniques, it stands out among all tea types. 


The beauty of oolong tea lies not only in its flavor but also in the craftsmanship that goes into producing it. The variation in production methods, geographical locations, and even the weather during processing means no two batches of oolong tea are ever exactly the same. 


In this article, we will explore the delicate art of making oolong tea, dive into its different varieties, and explain why it’s such a beloved tea worldwide.

The Intricate Process of Making Oolong Tea

The production of oolong tea involves a sophisticated and labor-intensive process that sets it apart from other tea varieties like green or black tea. While all teas come from the same plant, Camellia sinensis, it’s the method of processing that gives oolong its unique flavor profile.

Key Steps in the Oolong Tea Crafting Process:


  • Withering: The tea leaves are first withered under the sun to reduce moisture and soften the leaf structure. This step is essential for the subsequent processes.
  • Shaking: This step is the most defining feature of tea production. The leaves are gently shaken to bruise the edges, which promotes oxidation. It’s during this stage that the leaves start to develop the signature flavor and aroma of oolong tea. The method, intensity of shaking, and the weather conditions during this process can vary, creating a wide range of flavor profiles. The shaking process encourages water movement within the tea leaves, where water moves from the stems and veins to the surface of the leaves and then evaporates. This water loss impacts the tea's final fragrance and taste.

  • Oxidation : Unlike green tea, which is unoxidized, and black tea, which is fully oxidized, oolong tea undergoes partial oxidation. This oxidation process can vary between 10% to 70%, giving rise to different types of oolong tea, from lighter, more floral notes to darker, roasted flavors.
  • Fixation : After the desired level of oxidation is achieved, the leaves are heated to halt the oxidation process, locking in the flavors.
  • Rolling : The leaves are rolled to shape them into tight, twisted forms or small pellets, depending on the desired appearance. This rolling process also helps release the oils and flavors in the tea leaves.
  • Roasting : Some oolong teas undergo a final roasting process, which can further develop the flavor, adding a rich, toasty aroma to the tea. This step is more common in darker oolong varieties, while lighter oolongs often skip this process.

Famous Oolong Tea Regions and Varieties

Oolong tea is produced in several regions, each offering its own distinct taste, texture, and aroma. The most well-known oolong-producing regions are in China and Taiwan, each contributing something unique to the world of tea.

1. Wuyi Rock Tea from Fujian, China


Wuyi Mountain in the Fujian province is perhaps the most famous region for producing oolong tea. Wuyi Rock Tea, also known as “yancha,” is grown in the rocky terrain of the Wuyi Mountains, giving the tea its characteristic mineral-rich flavor, often referred to as a “rock taste.” The tea is known for its complex layers of flavor and aroma, ranging from floral to roasted notes.Within this region, tea is classified based on where it is grown:

  • Zhengyan : This refers to tea grown in the core rock area, considered the highest quality.

  • Banyan : Tea grown in the peripheral regions around the core.

  • Waiyan : Tea from areas outside the protected national park, which is still high-quality but doesn’t carry the prestigious "yancha" label.


The variety of Wuyi rock teas is vast, with over 800 distinct types of tea bushes recorded, many of which are named “famous bushes.” The most well-known types include Da Hong Pao, Shui Xian, and Rougui.

2. Anxi Tieguanyin from Southern Fujian, China


In southern Fujian, the Anxi region is renowned for producing Tieguanyin , one of the most beloved oolong teas in the world. 


Tieguanyin is characterized by its floral fragrance, light oxidation, and tightly rolled leaves that unfurl beautifully when steeped. The flavor is often described as smooth, creamy, and floral, with hints of orchid.


Tieguanyin can be found in different levels of oxidation and roasting, giving it a wide flavor spectrum, from bright and floral to richer, roasted versions.

Phoenix Dancong, produced in the Guangdong province, is another famous type of oolong tea known for its intense and varied aromas. Dancong teas are harvested from single tea bushes, each offering a distinct flavor profile. 


The most famous aromas include Osmanthus, Ginger, and Almond. One of the most unique and surprising varieties is “Ya Shi Xiang,” which translates to “duck poop aroma,” a name stemming from its unusual fragrance.


Dancong teas are typically darker and more oxidized than Anxi Tieguanyin, with a fuller body and richer, fruitier flavors.

4. Taiwan Oolong Tea


Taiwan has gained international recognition for producing some of the finest oolong teas in the world. The high-altitude tea plantations in Taiwan’s central mountain ranges are famous for their high-mountain oolongs


The cool, misty environment results in tea leaves with a bright, fresh flavor and a natural “cold fragrance” that is highly sought after.


Some of Taiwan’s most well-known oolongs include:

  • Ali Shan Oolong : Grown at high altitudes, this tea is floral, sweet, and buttery, with a refreshing finish.

  • Dong Ding Oolong : A more roasted variety, Dong Ding offers a complex flavor with hints of caramel, nuts, and honey.

How to Brew the Perfect Cup?

Brewing oolong tea is an art in itself. Here’s a simple guide to making the perfect cup of oolong tea:

  1. Water Temperature: For lighter teas, heat the water to around 185°F (85°C). For darker oolongs, slightly higher temperatures around 203°F (95°C) work well.

  2. Amount of Tea: Use about 1 to 2 teaspoons of loose-leaf tea per cup of water.

  3. Steeping Time: Let the tea steep for 3 to 5 minutes, depending on your taste preference. Shorter steeping times produce a lighter, more delicate flavor, while longer times bring out a more robust flavor.

  4. Multiple Infusion: Oolong tea is perfect for multiple infusions. With each infusion, the flavors evolve, so don’t discard your leaves after just one steep!
