Pu’er tea, renowned for its unique flavor and potential health benefits, is a type of fermented tea originating from the Yunnan province in China. Its production involves intricate steps that blend traditional techniques with modern methods to ensure the tea retains its distinct characteristics. Below is an overview of the production process of Pu’er tea in English.
1. Leaf Harvesting
The journey of Pu’er tea begins with the careful selection and harvesting of tea leaves, typically done during the spring when the leaves are tender and rich in nutrients. Leaves from older trees or bushes, known as “da ye” (big leaf) or “gu ye” (old tree leaves), are often prized for their superior quality. Harvested leaves are then quickly transported to the processing facility to prevent oxidation.
2. Withering
Upon arrival, the fresh leaves undergo withering, a process where they are spread out to lose moisture content naturally or through gentle heating. This step helps soften the leaves and浓缩 the flavors, preparing them for the next phase.
3. Rolling
After withering, the leaves are rolled into tight balls or long strips by hand or machine. Rolling promotes the release of natural juices, essential for the subsequent fermentation process. This step also helps shape the tea leaves into the desired form for Pu’er cakes, bricks, or loose-leaf forms.
4. Oxidation (for Sheng Pu’er)
For Sheng (raw) Pu’er, the rolled leaves undergo controlled oxidation, similar to how black tea is processed but to a lesser extent. They are left to rest in cool, ventilated areas for several hours to a day, allowing enzymatic reactions to occur, developing the tea’s initial aroma and color.
5. Drying
Once the desired level of oxidation is achieved, the leaves are dried to halt further fermentation. This is usually done using hot air or sun-drying, ensuring the tea maintains its freshly developed flavors and prepares it for long-term aging or immediate consumption.
6. Fermentation (for Shou Pu’er)
In contrast, Shou (ripe) Pu’er undergoes an accelerated fermentation process to simulate the natural aging of Sheng Pu’er. The dried leaves are piled up and sprayed with water to create an ideal environment for microorganisms to thrive. This controlled fermentation lasts from several weeks to months, resulting in a tea with a mellow, earthy flavor profile ready for immediate enjoyment.
7. Sorting and Grading
After drying or fermentation, the tea leaves are sorted and graded according to size, color, and quality. This ensures consistency in each batch and allows for the creation of different grades of Pu’er tea tailored to consumer preferences.
8. Pressing
Selected leaves may then be pressed into various shapes such as cakes, bricks, or logs for easier storage and transportation. This involves compressing the leaves under heavy machinery, often wrapped in cotton or rice paper, and allowing them to dry further in this compressed form.
9. Aging
Both Sheng and Shou Pu’er can benefit from aging, though Sheng Pu’er is particularly known for its transformation over time. Properly stored in cool, dry, and ventilated conditions, Pu’er tea continues to evolve in flavor, texture, and aroma, often becoming more valuable with age.
Conclusion
The production of Pu’er tea is a testament to the harmony between nature and human craftsmanship. Each step, from harvesting to aging, contributes to the tea’s unique characteristics, making it a cherished beverage worldwide. Understanding this process not only appreciates the artistry behind Pu’er tea but also enhances one’s enjoyment of its complex and evolving flavors.
