Mang Zhi

When one thinks of Gong Ting (Tribute Tea) one first thinks of Man Song and when one thinks of places of historical importance related to Puer tea in Xishuangbanna, one perhaps first thinks of Yibang or Yiwu, or maybe Gedeng, but Mang Zhi has its share too.

Man Ya is below Hong Tu Po and the quickest way to get up there is from the Xiang Ming road.

Once across the bridge, it’s quite a quick journey up to Man Ya where the ancient tea tree gardens are. Like many places here, the original village no longer exists and the inhabitants have all moved further down the mountain.

One reason that this has happened is because of a lack of water, or the need for it outstrips the resources. Another is simply convenience. Sometimes villages have also been moved by the authorities.

These trees, known by the villagers as Tian An Men provide a fitting entrance into the area where the gardens are. As with many places, the gardens are a mixed bag with some xiao shu near areas of older da shu and gu shu, but the general feeling is still good.

Most villagers make tea in or on the edge of the tea gardens, while several sell the fresh leaves they have picked to someone else from the village to process.

Many of the trees are similar to those in other Liu Da Cha Shan areas, but a few are significant, like the one below with a girth of 60 or 70cm.

The gardens have good ground cover with plenty of ‘za cao’ or weeds.

Lost in the undergrowth are a couple of tombstones which appear to be maybe Ming Dynasty and look like they were for government officials. One has been defaced, it seems by…. well you know the story. The other is still in relatively good condition.

It is said that tea from these gardens was also Tribute Tea – tea that was reserved for emperors or government officials.

Ya Nuo (You Le Shan)

There’s plenty of tea to be found on the road out from Jinghong to Jinuo Shan, but it’s not until you get some way past Jinuo Shan Town that you start to see anything that looks like you might want to try drinking it. And not until you get to Ya Nuo, some 10 km later, that you start to see some forest and ancient tea tree gardens.

Formerly known as Long Pa, Ya Nuo is a Jinuo village on the Menghun side of Jinuo Shan. It is one of two original ‘buluo‘ that the Jinuo inhabited. Originally, there were two extended families with fifty odd households living under one roof in a large bamboo structure with a grass roof. All the buildings in the village now are brick and concrete.

In the late 1970’s, when the Jinuo people were officially recognised by the National Government, the families in Ya Nuo were joined by families from the second village.

The Jinuo are a Tibeto-Burman group with a population of about 21,000. Their language shares some similarities with Burmese and belongs to the Yi branch of the Tibeto-Burman family. Jinuo people are animist and traditionally, hunter-gatherers and tea farmers. The Jinuo ‘creation myth’ is that they were born out of the sun drum – a large drum with pegs holding a taught skin over the end of the drum that radiate out resembling the sun’s rays. All Jinuo villages have a male and female drum which are of central importance in festivities as they embody sacred spirits.

Traditional Jinuo culture was egalitarian, with clan members hunting and farming together and sharing their spoils equally amongst all families. Tea was traded with ‘ma bang’ caravan traders in exchange for commodities that were needed, such as salt, cotton and ironware.

The most important festival is Temaoke or ‘Iron Forging Festival’ which falls early in the new year and is referred to as the ‘Jinuo New Year’. For Tamaoke, a cow is slaughtered and shared amongst the villagers such that each household gets an equal share of all parts of the animal.

Jinuo people tradionally make tea by wrapping it in a large leaf and roasting it in the embers of a fire. The leaves are then removed and brewed in a length of bamboo,or nowadays, in a large kettle. The resulting tea is strong and sweet.

Older Jinuo people – particularly women, chew betel nut ‘Burmese style’ using areca nuts and betel leaves and continue to wear traditional dress, but most younger people now only do so for special occasions.

At Ya Nuo, there are 2,800 mu of old tea tree gardens, owned by the original families of the village. In the 70’s, a co-operative, that is now defunct, was set up and tea bushes planted around the village. The later arrivals have no old tea tree gardens.

From the back of the village an area of protected forest extends all the way to Menglun, and it is mostly in this area that the ancient tea gardens are to be found, at altitudes ranging from 1300 to 1700 meters.

Naka

Naka -(Menghai Mengsong)

Naka is a Lahu village above Menghai Mengsong with around 100 households. They have a compratively small area of old tea gardens – about 500 mu of old tea trees. As early as the 1970’s tea manufacturers were sourcing tea from here. Read more about Naka here.

Conversations – On Picking Tea with Professor Chen

Like Picking Money from Trees III

I thought it would be interesting to get a more learned view on the issue of over-picking old tea trees. There’s always plenty of homespun logic available, but less easy to hear from the mouth of an academic, so I decided to get in touch with someone I’ve known for a year or so who’s just that: Professor Chen is on the staff at South China Agricultural University. He’s in the Tea Science Department.

I posed the question to him: When is an old tea tree over-picked?

His reply went pretty much like this:

‘On the problem over-picking tea trees, the main thing is to consider what is ‘appropriate’ picking. The aim of appropriate picking is to ensure a basis of a good, stable yield, to accomplish both ‘regular production’ and to ‘cultivate the tree’ – there is a paradox between the two.

The leaves of camelia sinensis are a vital organ which through the process of photosynthesis give the tree life. To maintain the trees strong vitality it is imperative to maintain stable, abundant foliage. The tree’s total leaf-surface area is an indices of its life-force.

At the same time, tips and young leaves are predominantly picked for tea production; appropriate picking practices can increase yield and also ensure the longevity of the tree. Accordingly, normal tea picking methods are to leave leaves on the tree. Research has clearly shown that if during spring picking a large leaf is left unpicked on the stem and in summer, the ‘fish’ or ‘milk’ leaf is left, it can improve both the quality and yield of the tree two years later.

Old tea tree gardens are somewhat different from plantations. They are less well managed and trees are more easily damaged. If through picking, the tree’s leaf area is reduced too much, i.e. too few leaves, it inevitably leads to early aging of the tree and in extreme cases, its death. Clearly, an appropriate degree of picking is important to maintain old tea tree gardens. Unfortunately, at the moment, there are no scientific research reports on appropriate approaches to harvesting of old tea tree gardens.

He suggested:

1. Old tea trees should not be picked harshly, (that is to say, pick the tree clean – all leaves, irrespective of size – in one go). Each time the tree is picked, a portion of the leaves must be left on the tree.

2. In the spring, during the first and second flush, a large leaf should be left on the stem because June is the time when the tree will lose leaves. In the summer, a ‘milk’ leaf should be left and in autumn, again leave a large leaf.

3. Pick according to the condition of the trees foliage; if old leaves are few, leave more on the tree. If old leaves are plentiful, pick more. In times of drought of course more leaves must be left on the tree. The older the tree, the easier it is to damage its life-force, so it is even more important to leave a proportion of tips and leaves on the tree.

4. When a tree is old it is very easily affected by over-picking. The tree is past its most productive stage and is in a period of decline.

Further research needs to be conducted to understand how over-picking impacts the quality of old tree tea.’

Some people say that the of type approach suggested by professor Chen is not that easy for tea farmers to take on board, and a simpler approach of getting them to re-establish traditional practices in cases where they have been lost would be more effective and would have the same result. However, it’s not all tea farmers who have a lore of tea cultivation in their culture – and certainly not of commercial tea production.

So it’s clear, if not conclusive, that there is, or at the least, there is potential for, a problem. But not so clear how widespread the problem is or how to deal with it. It’s unlikely the regional government, even if it had the will to grasp the issue, would have the ability to police it. So the onus of responsibility is on the farmers and the people who buy their tea.

Bada Wild Tea Tree – The end

Bada Cha Wang Shu

In the early 1960’s Yunnan University of Agriculture and Yunnan Tea Reasearch Institute conducted research on an ancient tea tree in the Da Hei Shan rain forest. The wild tree – camelia sinensis var. taliensis (Var. Dali), was at an altitude of 1900 metres, had a girth at its base of 2.5 meteres and was 34 metres tall. It was dated at 1700+ years old. It was said to be the worlds oldest living tea tree and helped add weight to the argument that southern Yunnan is the home of the tea tree.

The tree is said to have been weakened by termite and other insect infestation and also that wind and rain erosion further compromised its strength.

The trunk had become hollowed, which in turn had affected nutrient absorption. These factors coupled with wood rot caused the death of the tree which fell on the 9th of October, apparently, brought down by the wind.

The photo here was taken a few years ago by a friend, Wang Yun Song. The top of the tree had already been hit by lightening.

To try to understand the problem better, let’s first consider what the ‘norm’ is in order to understand what over-picking is.

Methods of picking tea:

To cut a long story short, there are four basic methods of picking that vary according to whether the intention is to maintain or encourage growth, according to season and prevailing weather, and the condition of the tree.

Typical leaf formations that are picked are tip and one, two, three and even four leaves. The leaves that are left on the plant affect growth; anything from 3 or 4 older leaves to a ‘milk’ leaf can be left on the tree.

Also, the age of the tree and the intention of the tea farmer further determine how the farmer picks the tree; whether they pick high or low, the outer or inner leaves, strong or gently.

See the notes at the bottom of the post for more detail

Here are images from Yunnan Cha Shu Zai Pei Ji Shu (云南茶树栽培技术) showing the basic approaches to tea picking. The fourth approach discussed below uses a combination of the the following methods. Puer tea uses the same approach though typically with Puer tea there has been less rigorous adherence to these standards with tip and four leaves not being uncommon.

Tree Age, Season and Picking Frequency

Tea trees are generally defined by three phases: young, mature and old. Tea plants in their prime have vigorous growth and can be picked several times a year. The picking encourages further growth so, in this way, productivity can be increased. Borrowing liberally from Yunnan Tea Cultivation Techniques:

A tree that has reached maturity is in its prime. It has many branches and its foliage is plentiful. It has a well developed root system and a strong capacity to transpire. Its ability to photosynthesise is strong. At this stage a tree is at the height of its productive cycle, producing plentiful, quality tea leaves. At this point it is important to maintain the trees abundant foliage. In this phase of the trees life the tree can be picked more lightly (i.e. leaving more leaves on the tree) in the spring, pick more strongly in the summer, and in the autumn leave ‘milk’ leaves on the tree.

To maintain the trees foliage density, spring picking should leave the ‘milk’ leaf, summer, leave one large leaf, and in the autumn again leave the ‘milk’ leaf. At the same time as paying attention to the trees condition, ‘leave fewer leaves higher in the tree, more leaves lower. Leave more leaves on the outside of the tree, fewer in the middle.‘

Once a tree has reached an old age, it’s growth is less vigorous, it’s ability to photosynthesise is no longer at its peak and the tree becomes weaker. The trees organic compounds are reduced. ‘Chicken feet‘ branches begin to appear in the crown of the tree and new growth is weaker. Branches begin to die. At this stage, picking should be stopped for one or two seasons to allow the tree time to recuperate…..

Typically, tea bushes are generally picked three times in the spring, again in the summer, and then again in the autumn. Occasionally, also in winter or very early spring.

Mature tea trees are typically not picked in the winter, but are still often picked two or three times in the spring and again in the summer and autumn.

When a tree reaches an old age, it is accepted practice to reduce the number of times it is picked. In this way, an older tree may be picked once or twice in the spring and then again in the autumn. Though summer picking is often considered necessary to promote an autumn harvest. Trees in their ‘N’ hundreds of years may well only produce leaves in the spring, so are only picked once.

Clearly, appropriate-picking must take into account the season and age of the tree in order to preserve tree health.

From Yunnan Cha Shu Zai Pei Ji Shu

1. The aim of this method is to encourage growth in the crown of a bush or tree. This is typically used when plants are only a few years old. In this method, a stem is left till it has 5 or 6 leaves on it, or until it stops growing further leaves, and then the tip and two or three leaves are picked, leaving 3 or 4 older leaves still on the plant. Each flush is picked one or two times in the same way – picking the upper leaves, leaving the lower to encourage the plant to branch and produce more profuse foliage in the crown.

2. The second method is a combined approach. In this method, trees are left to grow till they have tips and 3 or 4 leaves, or sometimes tips and 4 or 5 leaves before picking, at which point, tip and two or three leaf formations are picked, leaving one or two mature leaves on the tree. The aim is twofold: to encourage growth and to harvest tea. The decision to leave one or two leaves is determined by the season and the strength of the plant.

3. The third method is in Chinese referred to as ‘Leaving a fish’ method because the tea picker leaves a small leaf on the tree which perhaps looks like a small fish. It is also referred to as ‘liu nai ye’ – leaving a ‘milk leaf’ method. This is the principal method used in picking many kinds of tea. Generally, picking is done when there are new tip and one, two or three leaf formations. The small ‘milk leaf’ is left on the tree.

It is typical to pick a bush ‘clean’ as if this is not done it will influence the following flush.

4. The last approach is to pick ‘according to local conditions’. This is understood as ‘whichever leaves sprout first, pick first, whichever leaves sprout later, pick later’. i.e. ‘Pick those leaves that have reached the standard (e.g. tip & one, two or three leaves), those that have not reached the standard, leave till the next phase of picking, those that have already passed the standard, pick according to the standard.’ Superfluous leaves are left on the tree. In this way, the tree is picked clean and there is an even distribution of both young and older leaves and whilst suiting the requirements of the tea farmer, picking is determined by the trees age, rate of growth, season, etc. In this way a tree can be picked many times in a year.

Autumn Tea – Flowers, Nuts & Yue Guang Bai

Autumn is the time for tea flowers and nuts.

This is an ancient tea tree near Shi Tou zhai near the old Nan Nuo Shan Cha Chang.

On the way, I dropped in on a tea farmer we work with who had made some yue guang bai. Made, in this case, from old tea trees Yue Guang Bai is shade dried and does not undergo any other processing.

An inescapable sweet fragrance fills the work area where the tea has been drying. The tea is a little more astringent than spring harvest, but the fragrance is fine and the broth sweet. There is a little hint of fermentation, probably related to the slight oxidation that inevitably occurs during drying. This could be more or less, depending on the weather.

The spent leaves look a little like black tea as there is inevitably some oxidation in the drying process.

Over-picking Puer tea

Periodically, there is some comment online about Puer tea and over-picking of tea trees, so I thought it would be interesting to explore this further, and try to tease (‘scuse the pun) out what exactly this means in practice, and what the effects and implications are. It’s also important to consider this in relation to the Puer tea market to understand how it too may be impacting tea cultivation practices.

The broad picture is that concerns about the quality of Puer tea are becoming more frequent, and the explanations typically include climate/drought, overpicking and the use of a range of methods that are aimed at increasing productivity.

There are a number of factors:

1. The last few springs have been particularly dry which has inevitably affected yield, if not flavour.

2. At least in recent history, prior to 2005, the majority of people in the Puer tea supply chain – farmers down to customers – didn’t distinguish between old trees and bushes when picking tea. Old tree tea was not specially sought after so there was not the potential to over-pick and stress trees that there is now.

3.There is increasing demand for tea, with ever more people seeking a limited, and probably dwindling supply of old/ancient tree Puer.

4. Farmers have been using practices which, for them at least, are new – from turning the ground around tea trees to applying chemical fertilizers – in an attempt to increase yield. There are concerns about how these practices are impacting tea quality.

4. In recent years, methods of picking have:

a) had the propensity to disregard time honoured wisdom about tea tree cultivation, especially vis-a-vis the impact of weather.

b) been minimally influenced by research and understanding that has emerged and is recommended by tea colleges, universities and government organisations.

b) possibly fallen prey to the pressure of demand amidst a growing global market and big economic shifts for local farmers, many of whom previously lived subsistence lifestyles.

If we assume that inappropriate-picking, above all other factors, is having an adverse effect on tree health and tea quality, we should first consider what is ‘normal practice’ for tea picking, and specifically for old tea trees.

Ban Zhang & Hekai Old Tea Trees

ma hou pao – 马后炮

A friend told me today of some news from Lao Ban Zhang and He Kai: “Ban Zhang and Hekai have decided not to pick summer tea.” It seems a little disingenuous since we’re already into the autumn tea season, but it’s a step in the right direction, as long as they haven’t changed their minds by next year. Or is it?

The issue of over-picking tea, particularly on old tea trees is important, and not that straightforward. There are some seemingly common misunderstandings about exactly what ‘over-picking’ implies.

Not picking summer tea, the least sought after/cheapest harvest of the year, is not going to suddenly make everything right if other issues aren’t addressed. Ban Zhang autumn gu shu is on the market at 1,500 yuan/kilo, so the cynic might say they can afford not to pick summer tea, but whilst it would have given trees a chance to recover a little had it happened, it won’t necessarily improve next spring’s harvest.

Over the next few posts, I hope to explore this issue further and try to get to a deeper understanding of what the issues are, and how they would best be resolved.

* ma hou pao, is an expression that translates as something like ‘Firing the artillery after the horses have charged.’ Rather like ‘shutting the door after the horse has bolted’.

There and Here – more on puer storage

After comparing two Bulang Peak teas whilst I was in the UK, I thought it might be interesting to bring some of the 2010, UK stored tea back to ‘Banna to compare with some of the same tea that has been stored here in Jinghong.

This therefore, is more an ‘apples with apples’ comparison than the one in the UK which was comparing a 2010 tea stored in the UK for 18 months with a 2011 tea that had been in Jinghong. This time we have the same tea, same batch.

UK cake on left, 'Banna on the right

The first thing is that the difference between the teas is not that obvious. Looking at the colour of the cakes, the broth colour and the dregs, there is some difference to be detected, but it’s not that pronounced.

There is a slight difference in colour between the two cakes – most visible in the tips which are a little darker in the ‘Banna stored tea and in the slightly ‘greener’ hue to the UK stored cake. The top photo (right) is the UK stored cake, the lower one the ‘Banna stored tea. It’s not obvious in the photos here but the ‘Banna tea also looks a little richer, more moist than the UK stored cake, but perhaps I’m just imagining that.

The broth also produces marked difference – at least of the kind that I might have anticipated.

The broth from the first steepings of both teas looks pretty similar in tone.

I started using these two cups – the UK stored tea is on the left – but then realised my mistake as the shape of the cups and their translucency was affecting the appearance of the broth.

So I switched to two identical cups to see how the appearance of the broth was altered. I tried to steep the teas as close to simultaneously as I could in order to minimise any differences caused by oxidation of the broth and steeped the UK stored tea first, so that oxidation would not exaggerate any difference.

As can be seen in the photo above, there is no very obvious difference. Possibly the broth on the left (UK) is a mite lighter than the ‘Banna broth. Both are the third steeping.

Here is the broth from both teas after steeping for 5 minutes. This time the broth on the right (‘Banna) is more noticeably darker, but it’s still not much.

The difference is most clear in the flavour – perhaps as one might have expected. The UK stored cake has kept more of its youthful floral/fruity notes and is very sweet. At the same time it is very slightly more astringent than the ‘Banna stored tea.

The ‘Banna stored tea has lost most of those fruit/floral notes and has started to show hints of something deeper, though as yet, no obvious chen wei. Both teas, when pushed, show a decent kuwei and both resolve quickly to produce a good huigan.

So is there a conclusion?

Of sorts, there is an interim one. It could be that the astringence in the UK stored cake is due to the fact that it has aged more slowly than the ‘Banna tea (and we have forgotten how it was when young) and that with further storage it will diminish. The other possibility, it seems, is that it has been influenced by the dryness of the UK conditions and this has produced the astringence. Only further storage time will tell.
