Anhua and compressed dark tea - bricks, logs and golden flowers

Among the dark teas (heicha) there is a region that grew into a true legend: Anhua in Hunan province. It is one of the cradles of Chinese post-fermented tea, famous for forms you will not see anywhere else - from pressed bricks to a giant log of dozens of kilograms wrapped in bamboo. Anhua is the homeland of the famous Fu Zhuan brick, covered inside with the golden flowers of a beneficial fungus, and of Qianliang Cha, the thousand-tael tea. They are teas of a deep history, reaching back to the Ming dynasty, and of unique forms tied to the old trade on the tea road. Here is a guide to Anhua: where this compressed dark tea comes from, what the golden flowers are, what the Qianliang log is and why the region has heritage status.

Anhua - the homeland of dark tea

Anhua is a county in the city of Yiyang in Hunan province, one of the main regions of Chinese dark tea (heicha). It is a post-fermented tea, processed by microorganisms, of an earthy, mature character - a separate world from green or black. Anhua is famous for several characteristic forms, traditionally divided into three groups: three tips (San Jian - the Tianjian, Gongjian, Shengjian teas), three bricks (San Zhuan - Fu Zhuan, Hei Zhuan, Hua Zhuan) and one roll (Yi Juan - the famous Qianliang Cha). This shows that Anhua is not one tea but a whole family of forms and types. The region has a deep tradition reaching back centuries. Understanding that Anhua is the homeland of compressed dark tea of many forms is the starting point for the rest. It is one of the most important and characteristic regions of heicha. We cover post-fermentation itself more in post-fermentation in heicha.

Why the tea is compressed

A characteristic feature of Anhua dark tea is its compression into dense forms - bricks, logs, cubes. Where did this idea come from? The answer is historical and practical. Anhua lies far from the old markets, and the tea was transported over thousands of kilometres on the tea road, to Russia, Mongolia and even Europe. Compressed tea was simply more convenient to transport: it took up less space, was more resistant to damage and easier to count and pack than loose leaves. But compression also had an advantage for the tea itself: the dense form favours a slow, controlled post-fermentation and maturation over time, as in the case of pu-erh. This is why dark teas are often compressed into bricks or cakes. The form is therefore a combination of transport practicality and the favouring of maturation. Understanding why the tea is compressed explains these unusual shapes. It is the heritage of the old trade written into the form of the tea.

Fu Zhuan and the golden flowers

The most famous tea of Anhua is Fu Zhuan - a compressed brick of dark tea of a unique feature: golden flowers (Jin Hua). They are fine, yellow specks visible inside the brick when you break it. Fascinatingly, it is not a fault nor a random mould, but a beneficial fungus (Eurotium cristatum), which in the case of Fu Zhuan is deliberately introduced into the tea, to improve its flavour. The golden flowers develop during a special stage of fermentation in controlled conditions of humidity and temperature. They add to the tea characteristic, sweet, mushroomy, gentle notes and deepen its mature character. This is why Fu Zhuan is so prized - the golden flowers are a mark of quality and a unique flavour. The producer aims for their abundant development as a sign of a successful, healthy fermentation. Understanding that the golden flowers are a desired fungus, and not contamination, is the key to this tea. It is the tea equivalent of the noble mould in cheese. We cover this fungus more in post-fermentation in heicha.

Qianliang - the thousand-tael log

The most spectacular form of Anhua is Qianliang Cha, the thousand-tael tea. It is a giant, compressed log of tea, wrapped in bamboo, weighing about 36 kilograms and measuring over a metre and a half tall - a true colossus among teas. The name refers to an old unit of weight (taels). This enormous roll is compressed from mature leaves and stems, and its form is the peak of the art of compressed dark tea. The flavour of Qianliang changes dramatically with age: young it tastes of pine smoke, and matured for a decade or longer it transforms into something extraordinary - a cool, sweet, almost medicinal tea of a famous, fresh note of watermelon rind. It is a collectible tea, maturing for years like the best pu-erh. Understanding that Qianliang is a giant, maturing log shows how far the art of compressed tea can go. It is one of the most remarkable objects in the world of tea.

The table shows the diversity of Anhua: from bricks with golden flowers, through giant logs, to looser tip teas. It is a whole family of forms of one compressed dark tea.

History and the tea road

Anhua has a deep, fascinating history. Although tea drinking in Hunan reaches back to the Tang dynasty, the identity of dark tea (hei cha) as a particular commodity crystallised in the Ming dynasty. A key moment is the year 1524, when in a memorial to the throne the first written mention of the production of dark tea in the region appears. From then on the fame of Anhua grew. The peak of prosperity came in the Qing dynasty, when Anhua tea was exported through the famous ten-thousand-mile tea road to Russia and even to Europe. It was precisely this distant trade that shaped the compressed forms of tea, convenient for transport. Anhua was therefore not only a region of production but also an important link in the old tea trade. Understanding this history shows that the forms of Anhua are not a whim but the heritage of centuries of trade. We cover Chinese tea more in Chinese tea.

Heritage and maturation

The uniqueness of Anhua was recognised at the highest level. In 2008 the traditional craftsmanship of making Qianliang and Fu Zhuan tea from Anhua was inscribed on the second list of China’s national intangible cultural heritage. It is a recognition that the art of compressed Anhua dark tea is a precious heritage, and not just a product. Like pu-erh, the dark teas of Anhua deliberately mature with time - the compressed form favours a slow microbial transformation over years. Young Anhua tea is often rawer and smokier, and matured it mellows, sweetens and gains depth. This makes them collectible teas, prized the more the older they are. The key is proper storage, allowing the microbes to work healthily. Understanding that Anhua is a living heritage maturing with time completes its picture. We cover the maturation of dark teas more in pu-erh sheng and shou.

How to sense it in the brew

Anhua dark tea is easy to recognise by its characteristic profile. The brew is dark, from red-brown to deep, and in the flavour earthy, woody notes of forest floor dominate, sometimes mushrooms and mature, sweet tones. Fu Zhuan with golden flowers has a characteristic, gentle, mushroomy sweetness and smoothness. Young Qianliang is often smoky and rawer, and matured it surprises with a cool, sweet, almost medicinal note of watermelon rind. Unlike an astringent young tea, mature Anhua is gentle, smooth and soothing. If a tea is dark, earthy, gently sweet and comes from a compressed brick or log, that is a good clue that it is Anhua. It is worth crumbling off a piece of the brick and brewing it many times, because dark tea withstands numerous infusions well. Over time you will start to recognise the earthy, mature character of Anhua. It is a higher level of appreciating tea.

The essentials in brief

Let us gather it up. Anhua in Hunan province is one of the cradles of Chinese dark tea (heicha), famous for its compressed forms. The tea is compressed into bricks and logs for historical reasons (the convenience of transport on the tea road to Russia and Europe) and practical ones (favouring slow post-fermentation). The most famous form is the Fu Zhuan brick with golden flowers (Jin Hua) - a beneficial fungus deliberately introduced for flavour. The most spectacular is Qianliang Cha, a giant log weighing about 36 kilograms, maturing for years like pu-erh. Anhua has a deep history from the Ming dynasty (first mention 1524) and national heritage status (2008). The teas deliberately mature with time, mellowing and gaining depth. Now you know where this compressed dark tea comes from, what the golden flowers are and why Anhua is a legend.
