Origin and history
Pu erh tea, a dark, fermented tea with a rich history, takes root in Yunnan province, China. Historically famous, this tea has endured a development closely intertwined with China's trade and cultural exchange.
Old empires and the tea horse road
At the time of the Han dynasty, the legendary 'Tea Horse Road' (茶马古道, Chá Mǎ Gǔ Dào) emerged. This trade route connected remote Yunnan with the rest of China and neighbouring countries. Tea was exchanged for horses and other goods, which was essential for the expansion and consolidation of the Chinese empire. The route had far-reaching implications for the region's social and economic fabric, transforming Yunnan into a critical hub for the spread of tea.
The Qing dynasty to the present
During the Qing dynasty, Pu erh tea gained prominent recognition and appreciation, even at the imperial court. The quality and varieties of tea reached new heights and production methods were standardised. China's cultural and culinary traditions went hand in hand with the refinement of Pu erh. To this day, Pu erh tea remains an important part of the Yunnan identity and enjoys worldwide fame for its unique flavours and purported health benefits.
What is Pu erh tea?
Pu-erh tea is known for its unique fermentation process and deep, complex flavours. Originating from the Yunnan province in China, it constitutes a special class of dark tea appreciated all over the world.
Definition of Pu-erh
Pu-erh tea, sometimes written as pu'er, puer, or pu'erh, is a type of dark tea traditionally produced in the Yunnan province of China. Fermentation forms the core of the production process, causing the tea to develop a distinctive aroma and flavour. Unlike other teas, pu-erh undergoes a post-fermentation process, meaning it continues to mature and evolve even years after production.
Differences between Raw and Ripe Pu-erh
There are two main varieties of pu-erh tea:
- Rawful (sheng) pu-erh: this variety undergoes a natural maturation process after initial fermentation. Sheng pu-erh can mature for years or even decades, with the flavour developing gradually.
- Mature (shou) pu-erh: here, an accelerated fermentation process is applied to imitate the tea's maturation process. This results in a softer and richer profile that is more readily accessible for consumption.
| Species | fermentation process | Maturation |
|---|---|---|
| Rawful pu-erh | Natural, slow | Years/Decades |
| Mature pu-erh | Accelerated, artificial | Shorter |
The Camellia Sinensis plant
Pu-erh tea comes from the Camellia sinensis plant, which is known to be the source of all traditional teas. The tea bushes in Yunnan are renowned for their age, and the region's rich biodiversity contributes to the complexity of pu-erh flavours. The leaves are harvested, dried and then rolled before undergoing the unique fermentation that gives pu-erh its distinctive qualities.
Production process
The production of pu erh tea is a fascinating process that combines traditional methods with natural maturation that creates its unique flavour and aroma.
Picking and Withering
During picking, only the best leaves and buds are selected by hand. Once the leaves are picked, they undergo the process of withering where they are spread out on bamboo mats to partially dry. This is crucial to reduce moisture content and promote the oxidation process.
Fermentation and oxidation
After whiteing, the special fermentation process begins. For 'sheng' (raw) Pu erh tea, the fermentation process is natural, which can take years. 'Shou' (mature) Pu erh tea undergoes an accelerated fermentation process called wo dui, in which the tea leaves are moistened and kept warm in a controlled manner to stimulate fermentation. Oxidation takes place during this process and can vary depending on the desired flavour intensity.
Moulding and compression
The fermented tea leaves are then pressed into various forms, including cakes, bricks and birds' nests (tuos). Before forming, the moisture of the leaves is checked to ensure even pressing. Compressing is essential to maintain shape during the long ripening process and is often done with a traditional mould and weight, either manually or by machine. The tea lover can then break it with a tea knife and prepare it with a gaiwan.
Health benefits and medical uses
Pu erh tea, derived from the Camellia sinensis plant, is known for its impressive health benefits. Fans appreciate it not only for its deep, earthy flavour, but also for its positive health benefits, such as promoting weight loss and lowering cholesterol.
Blood pressure and cholesterol
Pu erh tea has an impressive ability to regulate cholesterol levels and can help lower high blood pressure. Science shows that drinking this tea regularly can lead to a significant decrease in both LDL cholesterol ("bad" cholesterol) and an increase in HDL cholesterol ("good" cholesterol).
Weight loss and digestion
This thousand-year-old beverage is an ally in the battle against the kilos. Pu erh stimulates weight loss and promotes healthy digestion. By improving metabolism rate, it helps a person burn calories more effectively. Moreover, it supports digestion by speeding up the breakdown of fats.
Antioxidants and heart health
Pu erh tea is rich in antioxidants, which counteract cellular damage and may help protect against heart disease. Studies suggest that the antioxidants in Pu erh support heart health by promoting blood circulation and stabilising blood sugar, reducing the risk of heart-related diseases.
Cultural significance
Pu-erh tea has deep cultural significance in China, merging indigenous customs and traditional Chinese medicine.
Pu-erh in Chinese medicine
In Chinese medicine, Pu-erh tea is highly valued for its health-promoting properties. It is believed to help with digestion, fat reduction and detoxifying the body. The fermented tea, rich in antioxidants, is traditionally used to restore balance in the body and support the immune system. Consistent use of Pu-erh is also said to contribute to improved circulation and reduced risk of cardiovascular disease.
Pu-erh and Dai Culture
The Dai ethnic group, from the Yunnan region of China, has a long history with Pu-erh tea. The Dai community has a rich tradition of cultivating and consuming this tea, with it being an integral part of social ceremonies and daily use. The unique terroir of Yunnan plays a crucial role in the tea's distinctive flavour, which is closely linked to the identity of the Dai culture. Pu-erh is more than just a drink for the Dai; it symbolises their connection with nature and respect for traditional farming methods.
Drinking Pu-erh tea
Pu-erh tea, often described as the 'fine wine' among teas, offers a unique experience that is particularly appreciated for its deep, earthy flavours that develop through the ripening process.
Brewing techniques
The brewing of pu-erh tea is an art form in itself. Enthusiasts recommend first briefly rinsing the tea leaves with boiling water to remove any impurities and 'wake up' the leaves. For actual brewing, people often use a Yixing teapot or a Gaiwan, both of which help develop the flavour. A basic guideline for brewing pu-erh is to use about 5 to 10 grams of tea for every 150ml of water. The ideal water temperature is just below the boiling point, around 95°C. The first infusion is usually short, around 15 to 20 seconds, after which the duration of successive infusions can be slowly lengthened to unlock a range of flavours.
Pu-erh tea comes in two varieties: raw (Sheng) and aged (Shou) Pu-erh. Brewing time and technique can vary depending on the type. Pu-erh tea can be re-brewed several times, with each infusion revealing a new layer of complex, earthy flavours that can delight the drinker.
Storing Pu-erh tea
The way pu-erh tea is stored is crucial to the development of its unique flavour profile. Unlike most teas, pu-erh tea can continue to mature and improve with time. An ideal storage area is well-ventilated, odour-free, and has a constant temperature and a certain level of humidity, allowing the tea to 'breathe' and mature gradually. Direct sunlight and strong odours should be avoided, as these can negatively affect the quality of the tea.
It is common to wrap pu-erh tea in paper or breathable material and then store it in a clay holder or wooden box. These materials support an ideal ripening environment and allow the tea to 'live'. When pu-erh is stored properly, the timely development of its earthy aroma and complex flavours makes for an enriched drinking experience.
Flavours and variants
Pu erh tea is a fascinating beverage with a rich variety of flavours and variants, which develop through careful maturation. Each variant offers a unique taste experience that intrigues tea lovers.
The flavour profile
Pu erh is known for its deep, earthy flavour profile that sets it apart from other teas. The maturation process gives this tea its distinctive flavour that is often compared to the complex notes of a well-aged wine. Young Pu erh varieties have a fresher, lighter flavour, while older Pu erh teas develop rich, deeper notes. The following characteristics can usually be recognised in Pu erh tea:
- Young Pu erh: Fresh, lively notes with a hint of sweetness.
- Mature Pu erh: Full-bodied, earthy notes likened to the aroma of rich soil.
Comparison with other teas
Pu erh tea differs from other popular teas such as green, black and oolong teas due to its unique ageing process and fermentation.
- Green Tea: This tea is not fermented and has a fresher, grassy flavour. In comparison, Pu erh offers a more robust and rich flavour profile that develops over time.
- Black Tea: While both are full-flavoured, black tea has a more pronounced malty character, while Pu erh is known for its earthy notes.
- Oolong Tea: Oolong tea balances between green and black tea in terms of fermentation. Pu erh, on the other hand, often has a stronger flavour development through its maturation process, much like that of wine, and can offer a surprisingly wide range of flavours as it ages.
The maturation of Pu erh can be compared to the ageing process of wine, with subtle flavours emerging more strongly as time passes. This makes each Pu erh tea an experience in itself.
