The Process of Making Oolong Tea

The production of Oolong tea is a traditional craft involving multiple intricate steps, each of which contributes to the quality and unique flavor of the tea. Below is an outline of the basic process involved in making Oolong tea:

1. Picking

The picking of Oolong tea typically takes place in spring. The standard for picking is one bud and three or four leaves, with the ideal stage being when the first leaf and the second leaf of the new shoot have opened to between one-third and two-thirds.

2. Withering

After picking, the tea leaves undergo withering, which can be done either in sunlight or indoors. The purpose of withering is to allow the leaves to lose some moisture and to initiate chemical changes within the leaves, preparing them for the next step in the process.

3. Oxidation (Rolling)

Oxidation, also known as “bruising,” is the most crucial step in the production of Oolong tea. It involves a series of actions, including tossing, resting, and re-tossing the leaves. This process damages the edges of the leaves, promoting enzymatic oxidation, which results in the unique aroma and color changes characteristic of Oolong tea.

4. Fixing (De-enzyming)

After oxidation, the tea leaves must be quickly heated to stop the fermentation process. This step, known as “fixing,” can be done by either pan-firing or baking the leaves. The purpose of fixing is to preserve the green color of the leaves and their fragrance.

5. Rolling

Rolling is the process of shaping the tea leaves into specific forms, whether long strands or pellets. This step also helps release the aromatic compounds within the leaves.

6. Roasting

Roasting is the process of removing excess moisture from the tea leaves, fixing their shape, and further developing their aroma. Oolong tea is typically roasted in stages, with an initial roast followed by subsequent roasts to refine the tea’s flavor and increase its shelf life.

7. Refining

Finally, the roasted tea leaves undergo refinement, which includes sorting, grading, and packaging to ensure the quality of the tea and meet market demands. The production techniques of Oolong tea vary depending on the region and specific type of tea, such as Wuyi Rock Tea, Tieguanyin, and Phoenix Dancong, each having its own unique crafting methods and styles.

Flavors of Oolong Tea

Understanding the diverse flavors and brewing techniques of Oolong tea will provide better insight into its unique taste profile.

Common Flavor Characteristics of Oolong Tea

• Floral Notes: Many Oolong teas have rich floral notes. This is due to chemical reactions that occur during the production process, releasing floral aroma compounds. For example, the Honey Orchid variety of Phoenix Dancong has pronounced honey and orchid aromas. This floral fragrance is fresh and elegant, and when brewed, the aroma is captivating, evoking the sensation of being in a garden.
• Fruity Notes: Fruity notes are another common characteristic of Oolong tea. Some Oolong teas have the aroma and taste of fruits like peach or longan. This is likely due to a combination of factors such as the soil nutrients absorbed during the tea plant’s growth, climate conditions, and the production process. Some Taiwanese high-mountain Oolong teas, for instance, have a subtle peach flavor, adding richness and allure to the tea.
• Roasted Aroma: Roasting is a crucial step in the production of Oolong tea, and roasted Oolong teas develop a unique roasted aroma. This fragrance resembles toasted nuts or baked bread, giving off a warm and full-bodied sensation. For example, after proper roasting, Dahongpao develops a caramel-like aroma. The roasted fragrance blends with the tea’s natural aroma, enhancing its complexity and depth.

The Influence of Different Fermentation Levels on Flavor

• Light Fermentation (10% – 30%): Lightly fermented Oolong teas, such as fragrant Tieguanyin, retain much of the original tea leaf flavor. These teas have a fresh and crisp taste, with noticeable floral and fruity aromas reminiscent of freshly picked flowers and ripe fruits. Due to the low fermentation level, there is less oxidation of compounds like polyphenols, resulting in a lighter, yellow-green tea liquor with a relatively mild taste and a subtle sweetness.
• Medium Fermentation (30% – 60%): Moderately fermented Oolong teas exhibit more complex flavors. While floral notes are still present, the tea starts to develop unique fermentation-driven aromas, such as honey-like sweetness. Fruity flavors become more pronounced and fuller, and the tea liquor takes on a golden hue. The taste becomes richer and more full-bodied, with a distinct and lingering sweetness. Some varieties of Phoenix Dancong fall into this category, offering a combination of floral, fruity, and tea-specific undertones.
• Heavy Fermentation (60% – 80%): Heavily fermented Oolong teas, such as some types of Dahongpao, have flavors dominated by the effects of fermentation. The roasted aroma is more intense, with complex notes like ripe fruit or caramel. The tea liquor is deep orange or even reddish, and the flavor is rich and mellow. The taste is full-bodied with a strong, long-lasting aftertaste, and the tea’s characteristic “rhyme” becomes more pronounced, delivering a powerful and impactful drinking experience.

Brewing Techniques for Oolong Tea

How exactly should you brew Oolong tea to achieve the best flavor? The following guidelines will greatly help you.

1. Water Temperature for Brewing Oolong Tea

Different water temperatures affect the flavor of the tea in various ways. Below are the recommended temperatures for different types of Oolong tea for your reference:

• Lightly Fermented Oolong Tea: It is recommended to use water at 85 – 90°C. Since this type of Oolong tea is relatively delicate, high temperatures can destroy its aromatic compounds and nutrients. Brewing with water in this temperature range helps to bring out the fresh floral and fruity notes.
• Moderately Fermented Oolong Tea: The ideal water temperature is between 90 – 95°C. This range allows the tea leaves to fully release their aroma and flavor compounds, showcasing the tea’s complex floral, fruity, and fermentation notes.
• Heavily Fermented Oolong Tea: For heavily fermented Oolong tea, you can use boiling water at 95 – 100°C. Due to the extensive chemical changes in the tea leaves, their structure is more stable, and the high temperature helps extract the deep roasted aromas and rich flavors, such as roasted notes and robust tea “rhyme.”

2. Tea-to-Water Ratio

Now let’s take a look at the tea-to-water ratio and how it impacts the number of infusions, along with other key factors.

• General Ratio: In general, the tea-to-water ratio for Oolong tea is 1:20 – 1:30. This means that for every 1 gram of tea leaves, you can use 20 – 30 milliliters of water. For example, if you use 5 grams of tea leaves, you can brew with 100 – 150 milliliters of water.
• Adjustments Based on Personal Preference: If you prefer a stronger tea, you can increase the amount of tea leaves, adjusting the ratio to 1:15 – 1:20. For a milder tea, you can reduce the amount of tea leaves, adjusting the ratio to 1:30 – 1:40.

3. Steeping Time

The steeping time of the tea leaves significantly impacts the flavor. Here are some important points to consider:

• First Infusion Steeping Time: The first infusion typically has a shorter steeping time. For lightly fermented Oolong tea, steep for 10 – 15 seconds; for moderately fermented Oolong tea, steep for 15 – 20 seconds; and for heavily fermented Oolong tea, steep for 20 – 30 seconds. The first infusion primarily serves to awaken the tea leaves, allowing them to unfurl and release their initial aromas and flavors.
• Subsequent Infusions: With each additional infusion, the steeping time can be gradually increased. For lightly fermented Oolong tea, add 5 – 10 seconds for each subsequent infusion; for moderately fermented Oolong tea, add 10 – 15 seconds; and for heavily fermented Oolong tea, add 15 – 20 seconds. High-quality Oolong teas can typically be steeped 5 – 7 times or even more, with each infusion revealing different layers of flavor.

Health Benefits of Oolong Tea

What are the health benefits of drinking Oolong tea? Let’s take a look at some of its key health advantages.

1. Boosting Metabolism

Several studies suggest that the compounds in Oolong tea may help to boost metabolism. For example, Oolong tea contains catechins, and according to some Japanese studies, catechins may increase energy expenditure. Epigallocatechin gallate (EGCG), one of the main catechins, is believed to promote fat oxidation by influencing enzyme activity related to fat metabolism, thus accelerating the rate of metabolism.

2. Lowering Cholesterol

Research indicates that the polyphenols in Oolong tea may help reduce cholesterol levels. A study on individuals with hyperlipidemia found that after drinking Oolong tea for an extended period, there was a reduction in total cholesterol and low-density lipoprotein cholesterol (LDL-C). Polyphenols may lower cholesterol by inhibiting its absorption in the intestines and regulating the expression of genes related to cholesterol metabolism in the liver.

3. Aiding Blood Sugar Control

Some animal studies have shown that the active compounds in Oolong tea may be beneficial for controlling blood sugar. Oolong tea may help regulate blood sugar levels by improving insulin sensitivity and enhancing the action of insulin.
