Taiwanese oolong tea is a type of semi-fermented tea that is renowned for its unique aroma and flavor. There are several important steps involved in the production of oolong tea, which are briefly outlined below:

1. Picking the tea leaves: High-quality tea trees are selected, and the tender leaves are picked during the appropriate season (spring and autumn). The quality of the tea leaves is affected by factors such as the cultivation area, climate, and tea tree variety.

2. Withering: The picked tea leaves are placed in a well-ventilated and shaded area to allow the leaves to naturally wither. This process causes the water in the leaves to evaporate, softening the leaves and generating a unique aroma.

3. Shaking: The tea leaves are gently shaken by hand or machine, causing the leaves to be abraded and the edges of the leaves to oxidize. This step contributes to the unique aroma and color of oolong tea.

4. Green-fixing: The tea leaves are placed in a high-humidity environment for a short period of time to undergo partial fermentation. This process helps to oxidize the tea leaves and form the unique characteristics of oolong tea.

5. Kill-green: The tea leaves are placed in a hot wok to suppress the enzymatic activity of the leaves, stopping the oxidation process. This step has a significant impact on the taste and aroma of the tea leaves.

6. Rolling: The tea leaves are rolled into tight strips, allowing the substances inside the leaves to fully dissolve and enhancing the aroma and color of the tea soup. The rolling process also affects the shape of the tea leaves.

7. Drying: The rolled tea leaves are placed in an oven or exposed to sunlight for drying. The drying process helps to extend the shelf life of the tea leaves and reduce the bitterness of the tea.

8. Roasting: Some oolong tea undergoes a roasting process to enhance the aroma and flavor of the tea leaves. The roasting process affects the quality and color of the tea leaves.

9. Grading and packaging: Finally, the finished oolong tea is graded and packaged to ensure consistency in quality.

Despite the seemingly complex process, each step contributes to the quality and taste of Taiwanese oolong tea. The unique color, aroma, and flavor of Taiwanese oolong tea are the result of the careful production and blending of these steps.
