Red Tea

 

Known as black tea in the West, red tea is one of the most commonly produced style of teas in the world. A well-made red tea by definition is fully fermented – all enzymes exhausted – making it the sweetest, smoothest category of all teas.

 

 

HISTORY

 

Unlike other teas, red tea has almost a linear history that’s simple, yet profoundly international and impactful. The world’s oldest red tea is Zheng Shan Xiao Zhong, aka, Lapsang Souchong. The origin of Xiao Zhong is not very clear with its birth estimated from 300-500 years ago. Before 19th century, it was the only known red tea existed (and many still argue it was wu long then). In fact, Zheng Shan Xiao Zhong was so singular in its existence, the name - only given after other red teas started to come about - literally means THE small-leaf tea from THE mountain, to distinguish itself from the rest.

 

Zheng Shan Xiao Zhong was the tea that Robert Fortune took from its still off-limit-to-foreigners origin of Tong Mu to India and what later became Darjeeling, ending China’s monopoly on tea in late 1800.

 

Because red tea was long viewed as a “messed-up” green tea by Chinese connoisseurs, its spread and production was largely organized for exportation purpose – quite a different route from the teas that were meant for Chinese aristocracies. This is a very important distinction as it sets the perimeter for the development of red tea’s terroir and making technique.

 

As beloved and popular as Xiao Zhong was in Europe, it has serious limitation to production and transportation due to its amazing but secluded location. The first Xiao Zhong substitute for organized tea production and exportation was Ning Hong – red tea from Xiu Shui, a city 360 miles northwest of Tong Mu, with easy access to waterways. Build upon the techniques Xiao Zhong had, and made specifically for the Western market, Ning Hong go through an unique process called “Gong Fu”, opening an era of Gong Fu red teas (see more explanation in the next topic).

 

From late 18th century to 19th century, multiple locations in China took turns to establish themselves as central hub for red tea exportation. Most notably are the Fu Jian Gong Fu Trio: Zheng He Gong Fu, Tan Yang Gong Fu and Bai Ling Gong Fu; and Qi Men Gong Fu, or known in the West as Keemun.

 

Throughout the development of red tea - its popular rise in the West and the rest of the world, and its direct cause to Opium War, which marks the decline of the Imperial China - few Chinese drank red tea.

 

Red tea remained primarily as an exportation tea that sells for lower price than other categories of teas in China, till 2005. A new red tea called Jin Jun Mei, from the fateful location of Tong Mu – home to Xiao Zhong, was created using only single buds and debuted with some say the most genius marketing tactic in Chinese tea history. Selling for a couple thousand USD a pound, Jin Jun Mei started what’s called Red Tea Renaissance. Since then, Chinese connoisseurs started to appreciate red tea with enthusiasm not seen before, reviving many historical red tea regions and inspired a few new, bringing up the overall red tea price in China.

 

 

MAKING RED TEA

 

Please note that the following is the best practice that tea makers do not necessarily follow nowadays.

 

Wilting – After the fresh teas are picked, the leaves are left out in a cool, shaded area to slowly loose its moisture. Some big leaf varietals are also sun-wilted first. This could take many hours. Most makers now use oxidation bed to wilt the tea, drastically accelerate the process but also compromise the quality.

 

Rolling – After the stems have lost enough moisture to snap, the wilted leaves are then rolled vigorously to sufficiently break the membranes to allow thorough oxidation that facilitates the fermentation later on. Red tea is also rolled for the longest among all teas, often times more than an hour.

 

Fermentation – The rolled leaves are shaken loose and evenly layered into a bamboo basket and then covered with wet clothes. One method is cold fermentation, where the tea is then left under room temperature over night, which is usually cold in the Spring in tea country. There’s also warm fermentation, where the tea is placed into a enclosed space with maintained moisture and temperature – can be done through charcoal ash and water bin, or machine. There’s also the wet fermentation with added moisture directly to the leaves, which is new and controversial. The time to ferment the tea varies depends on the environment. It can be as little as 2 hours or as long as over 10.

 

Picking – There will always be strings that are not fermented and will affect the flavor of final tea. While the tea is still wet and the discoloration easier to see, a tedious step where greener leaves are picked out takes place.

 

Baking – The teas are then evenly spread on baking trays and baked dry in the oven or over charcoal ash. Some are also lightly dried and rubbed in the wok first for shine and aroma. But the tea temperature at no times should be higher than 80-85C.

 

Ti Xiang – For details of the difference between this step and baking and other roasting methods, please check out our past blog post. This is a baking technique that is designed to enhance and purify the tea’s aroma, WITHOUT altering its original flavor profile. It is usually done at least three weeks after the tea had been baked. It is a tricky step that many opt to skip because if not done correctly can quickly ruined an otherwise mediocre tea. On the other hand, sometimes a red tea can be ti xiang twice, with usually three weeks time in between.

 

 

GONG FU HONG CHA

 

While it is also called “gong fu”, the term is not to be confused with either the martial art (written differently in Chinese) or the style of brewing that is called gong fu cha. Gong fu in Chinese means time and effort, so it is not a surprise that it is used to describe the following time consuming tea making techniques.

 

Traditionally, after a red tea had been dried, it is then broken into small segments using a technique called Da Dai. This is a highly skilled and interesting step where a tea maker rhythm swings a bag of tea to make contact with a stone placed on the ground. If not done right, the tea turns into dust and the person can hurt his back. However, when done expertly, the teas are broken following how naturally a bud and leave will fall off the stems, with rounded edges. It is a disappearing art; most tea makers nowadays chop the teas into smaller size using machine, safe and fast.

 

The broken teas are then sorted multiple times according to its length and width, into the many grades the tea maker sells. Traditionally, this is done using bamboo trays weaved with different sizes of slots on the bottom so only the desired size falls through. It is another highly expertized step that is very time consuming and can ruin the tea if not done correctly. Most teas are now sorted by machine.

 

For full demonstration of how Gong Fu Hong Cha is done, please check out our tea trip videos.

 

The “refining” steps were necessary to making Gong Fu Hong Cha because mass production and exportation called for standardization – both the tea’s flavor and its price.

 

Counter-intuitively, the most traditional red teas are the broken ones, because it was a tea made with a defined end purpose in mind – mass production. It was the very reason that made red tea popular internationally and dismissed by domestic connoisseurs for centuries. This is where the topic “does traditional means better” should be debated, or even more importantly, how do we carry on and improve without forgoing tradition.

 

 

ZHENG SHAN XIAO ZHONG

- Lapsang Souchong

 

Though for a while there’s only one Zheng Shan Xiao Zhong, now there have been multiple styles of teas coming out from the same region in the past decade that a listing of them is necessary to understand what really is a Zheng Shan Xiao Zhong.

 

Zheng Shan Xiao Zhong and its related teas come from the restricted national reserve area near Tong Mu Guan with two villages within the checkpoint being the most famed – Gua Dun and Ma Shu. Everyone not native to the villages within the area needs a special permit to go inside and it is completely off the limit to foreigners. A overwhelming majority of Zheng Shan Xiao Zhong both in the Chinese and overseas market are NOT from Zheng Shan, which is part of the tea’s name to signify the importance of its location.

 

Zheng Shan Xiao Zhong in the most traditional sense means a smoked broken red tea made with Qing Lou. Qing Lou, though in layman term actually means a pleasure house/brothel (yes, there are many Chinese jokes about this), in the tea profession it is the name of a unique smoke house built for making Xiao Zhong. The house is three-story high, with flexible bamboo sheets tiling its floors - one has to be careful and strategic walking on it to not fall through because it is not solid ground. Down below the Qing Lou is where a combination of local pine needles and pinewoods are burned and the smoke is channeled through brick cannels that are similar to the underground structure of a roman bath. Tea trays, depend on the stages of their making (wilting, drying, smoking), are “stuck” onto the wooden ceiling shelves right below each bamboo tile to be gently “flavored” by the smoke that comes up through spaces between bamboo weavings.

 

However, the real Zheng Shan Xiao Zhong was facing an unappreciative market in the 90s and early 2000s with many criticize it being inferior because it is a broken tea, and it is flavored (many claim it should not be considered a real tea). The following variation of Zheng Shan Xiao Zhong since then was created with the debut of Jin Jun Mei, pushing red tea to a new height of awareness.

 

You Yan Xiao Zhong – this is the only kind that resembles the traditional Xiao Zhong where the tea is smoked.

 

Zheng Shan Xiao Zhong Smoked and Broken, varies grades (consider this a prototype of Gong Fu Red Tea)

 

Zheng Shan Xiao Zhong Smoked but not Broken (more common now with less requirement on facility but a Qing Lou is still needed)

 

Wu Yan Xiao Zhong - Zheng Shan Xiao Zhong not smoked and not broken

 

Chu Kou Xiao Zhong -

This is a touchy point, but there’s a Lapsang Souchong directly smoked with pine grease or with added smoke flavoring for export-only teas. It’s easily identifiable with overly pungent smokiness. This tea is not sold nor drank in China.

 

Jin Jun Mei - Single bud red tea

 

Yin Jun Mei - Red tea with one bud and one leaf

 

Xiao Chi Gan - Red tea with one bud and two leaves

 

Da Chi Gan - Red tea with three leaves

Zheng Shan Xiao Zhong uses cold fermentation and because of its unique microclimate (above 1000m elevation in a relatively northern tea region, one of the coldest), the red tea from the area has a subtle but lingering sweetness and often has notes of apple skin. Jin Jun Mei is also known for being very umami.

It’s worthy noting that Xiao Zhong is also the name of the indigenous varietal in Tong Mu. However, unavoidably, there are many new varietals now including lots of cliff tea cultivars. This adds complexity to understanding the teas. Due to the very cold climate of the region and the late budding tendency of Xiao Zhong, it is usually the last tea region in China to harvest, even after the Wu Long season. Old varietal Jin Jun Mei (buds) usually harvest around mid April and Zheng Shan Xiao Zhong mid May.

 

 

QI MEN HONG CHA

- Keemun

 

Known for the outstanding fragrance that’s unrivalled by any other red tea, Qi Hong since its creation had occupied the first place among red teas. It is also the only red tea that’s ever made to a China’s Ten Famous Teas list – a prestige title. Qi Men is a township in the Yellow Mountain range, An Hui Province and the red teas from the region is often referred to as Qi Hong. The top prized locations in Qi Men are Li Kou, Shan Li, Ping Li - with Li Xi, Gu Xi, Ruo Keng of Li Kou demands the highest prices, in the said order.

 

Qi Hong started as a Gong Fu Red Tea and is still the most mature with its techniques such as Da Dai. However, since the privatization of tea making in the 80s and 90s, Qi Hong had been continuously reinventing itself to keep up with the market as well as work around the limitation of farmers tea making capacity (Gong Fu Red Tea needs space and additional labor).

 

Current styles of Qi Hong are:

 

Qi Men Gong Fu – broken and sold in varies grades

 

Hong Mao Feng (Red Mao Feng) – red tea with minimum shape making (all red teas have to be rolled). It is one of the most popular form of Qi Hong right now, and also a rough tea for making Gong Fu Red Tea.

 

Hong Xiang Luo – a red tea that’s been rolled into spiral shape, its name drew inspiration from the famous green tea, Bi Luo Chun.

 

Hong Song Luo – a red tea that’s been made into pearl shape, its name drew inspiration from the legendary tribute tea in Tang Dynasty, Song Luo.

 

The indigenous varietal of Qi Men is called Chu Ye, one of the most studied group varietal of tea, thanks to Qi Men being the home to An Hui Tea Research Institute (moved to Tun Xi early 2016). Common clone varietals of Qi Hong are Hong Qi #1 and Da Bai.

 

 

DIAN HONG

- Yun Nan Black

 

Every Chinese province has a one-word (single syllabus) acronym. For Yun Nan, it is Dian. Hong means red. Because red tea is known as black tea in the West, the translation for Dian Hong, though quite literal, is confusingly Yun Nan Black. Like the name suggests, Dian Hong comes from Yun Nan. Though Dian Hong is very much a new comer to the red tea party - created in 1939 - it is currently among the most popular red teas from China.

 

Though originally developed in Feng Qing of Yun Nan, Dian Hong is now produced throughout the province. Dian Hong price hierarchy currently follows the same convention as Pu Er, which is leading by terroir, then age of the tea tree, then crafting. Because varietal of Pu Er is closely related to the age of the tea tree, it is an assumed factor. The broad location reference of Dian Hong in the name suggests that it is a tea with lots of details yet to be classified and standardized, demands a generally lower price than other red teas.

 

Dian Hong by default is a big leaf varietal red tea that takes a string shape. It is generally known for having more body than its small leaf peers.

 

 

ONE MORE NOTE

 

Though each style of red tea have its own characteristics, there’s still consented flavor notes hierarchy of red tea following tea’s natural fermentation cycle. They are listed below as a general guideline.

 

Longan > Dry Red Dates > Yam > Fresh Red Dates (slightly sour)
