Placing sustainable, forest-based tea agriculture




I've not met up with Sasha Abramovich or Nok recently, and I finally did again this past weekend.  A local tea celebrity of sorts dropped by, Kenneth Rimdahl of Monsoon teas.  I'll say a little about what we tried and then run through some news related to Kenneth.  He's been doing a lot with a sustainable, forest-friendly tea sourcing that's the main theme here, with just a little on that meeting covered first.

a first outdoor tasting trial awhile back, last year


Tasting tea and hanging out


Sasha brewed two Tea Side teas for us, a 1980 sheng (reviewed here) and a 2006 sheng (re-reviewed here, in comparison with what turned out to be a different 2006 HTC Thai sheng).  It was interesting trying two teas I was already familiar with in a different setting.  The second tea is the first aged sheng cake I ever bought, so I have some at home, but I don't drink it often.  It's nice tea.

Sasha also brewed a few nice sheng samples from Tea Dee, commissioned or shop-produced tea versions that represent the best respected tea shop in Bangkok, owned by Khun Zhang.  Double Dog is as well known but for being a Chinatown cafe, and they also sell tea, but no other Thai business comes close to matching that shop's local reputation related to pu'er.  Oddly I've only visited them once, in a location that has since moved (now in Thanya Park), because that shop is way out towards the airport from where I live and work in the city center.  There's a nice park out there we visit once in awhile, Rama 9 / Suang Luang, but I never get my wife to agree to add tea shopping to the list of days' activities when we visit it.

Not much of a review of teas we tried so far, but I didn't intend for this to go into that.  There's more I could say about the Tea Dee cakes but it would only be a general impression due to writing this days later.  They seemed different from each other, generally sweet and floral in different ways, and like quite good tea material.  They didn't seem to be made in a drink-right-now modern style (more traditional instead), but not overly bitter, astringent, and unapproachable.  They seemed to represent tea that could still be a good value even if selling for over $100 per cake when "young," before aging; that's probably saying enough.

Kenneth brought a couple samples of interesting Ceylon / Sri Lankan teas.  I probably shouldn't say more about one that seemed unique in style and appearance since it represents a work-in-progress for a new product development.  A second (green tea, I think it was) was unique for being able to change color, to switch from the pale gold that green teas are to pink with a little lime added.  That transition capacity is familiar from blue pea / butterfly pea tisane but I've not seen actual tea that does that, until this one.  I definitely like green teas the least of any broad category but that tea was fine too.  The black tea version was a good bit better than "fine;" it was quite nice tea, and not exactly like other better Ceylon I've tried in style.

Onto news about Kenneth then, which does skip a lot of what we discussed that day, and how it went in general.  It was a nice outing.  We drank too much tea but I sort of saw that coming and only tried a couple of tisanes with breakfast.


Kenneth and Monsoon update


Monsoon opened a Bangkok branch around three weeks ago.  I've seen news related to that, but just didn't get around to visiting there or mentioning it here.  It's way out in the South-East of town, not as far as Tea Dee, but closer to that than to city center, my job (the main site), or where I live.  The second main site for the company I work for (not related to tea; the subject is a hobby interest) is actually out in Bangna, on Bangna-Trad road.  It's even further out than that Monsoon shop, and a ten minute drive from Thanya Park (but I use the sky-train here for commuting).

Monsoon's primary theme is selling tea blends, with a focus on Thai-produced forest-friendly tea.  I reviewed a white tea version a couple of years ago and that was nice.  Kenneth talked about that at a TedX talk a year or so back, and the Bangkok Post ran a story on him and the forest friendly tea theme. 

On a related subject, I ran through details of a different type of related sustainable-production initiative carried out in Laos in this post (which reviews two local tea versions), with a website of the related participating NGO covering more details.

I have mixed feelings about this forest-friendly theme, and the background can be a bit complicated, so that I'll say more about all that here than I did about trying 8 or 9 novel teas earlier in the post.  Kenneth is nice, and he seems genuinely concerned about that sustainability concern; at least that seems to be a good starting point.


Forest-friendly sustainable tea production


Let's get the reservation and potential problem out of the way first:  this theme is at least in part a marketing approach. 

Teas really are healthy, but when a vendor promotes how healthy a tea is they trying to make a sale based on ideas that aren't usually as well-grounded as they represent them to be.  I think there is a good chance that green tea is good for cardiovascular health, and there is some research evidence supporting that, but when a tea vendor makes that claim it comes across more as sales-pitch than them trying to be helpful and informative.  I don't drink green tea much anyway; I don't like it as much, and other versions would overlap in terms of beneficial compounds present.

Some of that type of concern probably applies here.  A complete critique of how the factors are likely to balance isn't possible, self-interest based marketing versus broader-interest based sustainability focus.  It is possible to run through my take on how "real" I think this particular sustainability theme is, so I will cover that.

It's real, but it's not an important factor if the consideration is limited only to being related to tea in Thailand.  Let's back up and examine why I think that (and note that it is only my impression, to an extent).

This 2008 research reference offers us a dated snapshot of tea production in Thailand:




This 14 year old production summary converts to a total land space of 75,076 rai used to make tea.  That converts to 29,600 acres, or 47 square miles, an area of 6 miles by 8 miles.  It's a good bit of land, but essentially nothing at all compared the land used to grow rice, fruit, or palm oil here. 

Let's check on that and use the latter (palm oil production) for comparison:

According to this reference there are (as of 2015) approximately 700,000 hectares of land in use in Thailand for production of palm oil.  That equates to 17.2 million acres.  Put another way there is 58 times more land in use to produce palm oil than tea in Thailand.  That's based on these numbers; tea production probably has increased, and I wouldn't be surprised if that palm oil estimate is on the low side, based on driving past palm plantations for hours in the South, lands that had been cleared of all native vegetation for that use.  The palm oil production growth and land-use are escalating much more quickly too, since the tea industry is probably quite a bit more developed and mature now, with demand leveled off, making it a lot more of a development concern, as shown by this reference:




That's happening mostly in the South of Thailand, related to what climate supports growth of that palm plant type best.  The general idea is that scale of tea production just isn't on the same scale as other agricultural production, so the risk for environmental destruction directly related to tea farming also cannot be.  For all I know logging impact may well be more of a competing concern in the North than other forms of agriculture are, and land-use study might not be as easy to pin down for that kind of thing.

That would seem to point back towards this being a good story that sells tea, a basis for presenting ideas through different channels to promote a business, but not mostly based on a real issue.  Not so fast though; there seems to be more to this, and it doesn't reduce to only being a factor related to tea.


Forest conservation as a broader trend


There are definitely competing interests that relate to land use and forest preservation; this much is clear.  Destruction of standing old-growth forests to produce tea may well be a relative non-issue, compared to the scale of other agricultural-use concerns, but preservation of those forests definitely is an issue.  Thailand, like most other countries, has set up environmental reserves and protections that tie to a broad range of concerns.  I highly recommend reading this background summary on Forest Management in Thailand, prepared by the International Forestry Cooperation Office, a branch of a government protection agency that also involves Thai Royal family support.  Their summary outlines the current status and goals:


...There is no doubt that remaining forests need to be protected and that deforested areas need to be replanted. Moreover, there is no disagreement that local people must be involved in conservation efforts if they are to succeed...

...Forest resources provide a multitude of goods and services, including pulp, timber, nontimber products, medicinal and edible plants, as well as other raw materials such as rattan and bamboo. More than 1,000 recorded species of plants contain medical properties and 30,000-40,000 households harvest them on a full-time basis. Furthermore, 60% of the rural population or roughly 30,000 communities living near forests rely on edible plants for their daily needs and more than 500 species of these plants are sold in local markets throughout the country... 





The past history and regulatory efforts in place described in that short work are too detailed to summarize here, even in citation sampling format like that.  One general theme meets back up with what Kenneth is promoting related to tea:

...Communities located within and near forests have been motivated to participate in the sustainable management of natural resources through well designed conservation policies and legal frameworks, especially those pertaining to forests, which have been amended to address rapid social change and emerging environmental issues...

...Thailand, which once exported timber, is now a net importer and has high expectations of the role forests will play in nature conservation. Since 1989, all natural forest (25% of total area) is protected by law from commercial exploitation...

...Community forests in Thailand are classified into two types: natural and rehabilitated or developed. They can be established on three categories of land: national reserved forest or public and overgrown areas; land under the jurisdiction of other government agencies (e.g., monasteries, educational institutes, military areas); and private locations.

The first type consists of natural forests where people in nearby communities join together to protect them in order to benefit from their productive capacity and to maintain their norms and culture... 


I'm sure that there are functional programs and other initiatives in place that support sustainable, natural-growth land use, even beyond what is described in that reference.  At the same time the more that minimal impact land use can enable economic development the more effective and functional those programs will be in practice.


One additional context detail:  the tea is already there


This part I almost left out, as familiar ground to me since I've been reviewing this relevant background for a couple of years (based mostly on input from Kenneth, and also other sources prior to talking to him), but it wouldn't be familiar to many.  The tea plants are already there, essentially growing wild.  Tea was introduced into areas in Southern China, Myanmar, Northern Vietnam, Laos and Thailand well over a millenium ago. 

Which forms of the tea plants are the most original and native, and the role people played in distributing them are debated, but the consensus take is that wild forms of Assamica (one of two varieties of Camellia Sinensis) first originated in Yunnan, and that movement of the plants to a broader region was probably helped out quite a bit by people.  Thailand was settled by waves of people from China and other places extending back well prior to known history.

It's really something of an unrelated tangent here, but I'll include a citation about the plant-history of tea that relates, and a link to support further reading:

The tea plant was initially domesticated in China over 4,000 year ago (Yamanishi, 1995)... 

...we calculated China type tea and Assam type tea as having first diverged approximately 22,000 years ago, and Chinese Assam type tea and Indian Assam type tea as having diverged from each other approximately 2,770 years ago... 


There is a lot more to that story.  The short version:  tea plants are there, growing relatively wild in the North of Thailand, almost certainly put there by groups of people who aren't well-documented by a known history (but some pre-history is described here).  Kenneth emphasizes that earlier use relates to miang consumption, to practices of eating tea that are common to those in Myanmar (and in Northern India, I think?), and probably other places.  I'm not sure if eating tea really did pre-date brewing tea, locally or elsewhere, or if it's possible to place the two in relation to each other as regional traditional practices over a long time-frame.

Deeper detailed history aside, what I'm trying to summarize here would seem very odd if the idea was to plant some sort of community farms inside forested areas, versus using leaf material from plants that are already growing there (the actual case).  If these forests are destroyed for alternate use, or perhaps even just used for logging (depending on tree-harvesting process used), many of the tea plants and other useful bio-diverse plant-life might be destroyed.



Onto conclusions


It might seem like I'm concluding that every little bit helps, and that what Kenneth is promoting is one small step in the right direction, joining other government initiatives and land-use themes.  That seems at least partly true, if potentially a bit optimistic.  Not all government programs are effective at achieving intended goals, and I'm not sure how much economic benefit "wild" tea development currently has on such concerns, or what the future potential is.

All the same these ideas map together in an obvious way.  The theory and broad government-control directive requires other steps and drivers to support it; that much was cited here in that Ministry of Natural Resources and Environment summary.  It's not "sustainable" in one deeper sense for only government restrictions and NGO monitoring and education efforts to prevent high-impact forest land use; a positive economic driver could potentially also play an important role.


Is it better for the Thai natural environment to buy Monsoon wild-grown tea instead of plantation-produced oolong?  Maybe a little.  There wouldn't be a significant effect from that personal choice on a small scale but to some extent the small inputs would "roll up."  I suspect that Kenneth and Monsoon's efforts round down to making no difference taken alone, but that all such forest-use initiatives considered together are a significant factor, and one that can potentially be extended. 

To me this leads directly on to considering other factors.  If you buy a tea blend sold in a small tin, what about the pit-mine impact from producing that metal, versus use of some other type of packaging?  The mine for the metal ore might be in Laos, with the packaging production in China, and the likely end point for the tin as a landfill in Thailand, with transportation related impact all through those steps. 

This is part of our current set of challenges; sorting out which inputs and causal connections really do make a difference, and identifying how to maximize the cumulative effects of our choices.  It starts out as simply as choosing paper or plastic bags, or deciding to carry re-usable cloth bags instead.  If one person's choice in some regard extends to a factor of a thousand times more impact than which tea source they choose then more focus is better directed there.

In conclusion, how much difference this really makes is hard to place.  But it is one representative part of a very important subject that does need to be addressed.  Probably palm oil farming represents a real land-use issue that needs to be considered and monitored at a national level, more so than tea production.  Of course China is destroying natural areas much faster to ramp up tea production there, because tea is a much larger industry there.


clear-cut tea farming (but not in Thailand or China)


It would be nice if personal beverage choices could make a marginal difference in long-term land use in Thailand.  To some limited extent Monsoon products represent that potential, whether that is actually the main driver for their sourcing framework or not.  I think Kenneth's intentions are good, but of course businesses also need to be profitable, so goals tend to mix.  If profit is motivating this development and natural-growth forest preservation and use is also being supported then it represents a case of multiple forms of values matching up.

For me personally I try to remain skeptical about claims and background descriptions made about tea across a broad range, but also stay open to new ideas, and remain somewhat optimistic.  Drinking a different version of tea won't make much difference, but helping make a little difference could reasonably be experienced as a positive thing.

Kinnari Tea sheng comparison (Nyot Ou district in Phongsaly, Laos)



I'm reviewing two sheng versions from Anna of Kinnari Tea; these should be really interesting.

They're Laos sheng, from the far North.  One lists it's from the "bai hao" cultivar, a tea plant type more typically used to make white tea.

William of Farmerleaf was also involved with an NGO project to conduct local training workshops in producing more standard and consistent sheng pu'er versions there, along with Anna and a supporting agency, with details about that in this video.

William mentions a link to more details about that project here, from the Comité de coopération avec le Laos (with an alternate Facebook page reference here).  Part of the introduction goes into that background:


In Nyot Ou, the northernmost district of Laos, tea trees grow in the wilds of the tropical forest covering the slopes of the mountains bordering the Chinese province of Yunnan. The wild tea stems from the variety Assamica, one of the two main varieties of tea. In China, this variety is called “the high tree with larges leaves”.

Growing tea has a long history in the Yunnan region: large tea leaves were used as medicine for at least three millenniums and seem to have already been a popular drink around the second century B.C.

Wild tea trees in Nyot Ou can grow as high as fifteen meters. Old pruning marks observed on some of them suggest that they could have be planted hundreds of years ago. In this case, they can be considered as “Ancient tea”, namely a tea tree resulting from a selection of wild tea varieties.


The rest of the background story is compelling.  I would highly recommend reviewing William's summary video explanation and at least scanning that NGO web page.

This really is the "wild, forest friendly" tea that comes up in discussion and sometimes in marketing claims.  The tea is something else; how it turned out depends on lots of factors, the plant type, growing conditions, processing, etc.  So I'll review it without adding more about all that, but I will pass on a few photos taken from that reference page to visually add more about it.

Review background


Something unusual came up related to this review; I was discussing my impression with Anna and it didn't match hers.  In particular that related to describing the level of bitterness in the Bai Hao version (sheng version made from a cultivar usually used for white tea production).  I decided to re-taste the teas, without referencing the notes, in order to see if my take was the same.  It was but it wasn't; related to that level of bitterness my impression was different.  

Instead of including the typical round-by-round description (which I now have two sets of notes on) I'll summarize findings for both from both notes.  I can't completely explain the discrepancy, the difference in interpretation or assessment of the aspects, especially that one, but I'll mention some possible factors in a section after the review summary.  It was interesting how even though the rest of the reviews seemed relatively consistent, beyond that one point about level of bitterness in one, interpretation of the flavor aspects did vary some.

Review


First tasting round, Bai Hao Left, Workshop version right






Workshop tea (I'll go tea by tea across rounds in this format).  This tea was on the subtle side but the character it did have was pleasant.  It was a little more intense than the other version related to flavor input, but the "Bai Hao" tea had a creamy fullness to the feel that filled in that experience more.  A warm tone stood out; described in different parts of both reviews as possibly related to autumn leaf or a warm version of mineral, like South-Western US sandstone.  Bitterness was very light; part of what might have been occurring related to seeing the "Bai Hao" version as bitter was noticing a relative difference (with more on that in the other review and explanation).

Some amount of floral tone was present in this version, which trailed into a light version of dried fruit in later rounds.  The tea was noticeably darker than the other version, related to the leaves, and the brewed liquid, which might indicate that it had oxidized a bit during processing (hard to imagine what else that could relate to).  That could also help explain the character.  It wasn't really like a black tea but the normal degree of bitterness dropping out and the flavors extending from light and bright into a warmer, softer, earthier range would all be explained by that.  It even had a mild savory quality to it (only picked up in one of the two review notes versions), a bit like sun-dried tomato.


Bai Hao plant-type sheng:  this tea was much milder in overall character, light in flavor intensity, with a degree of bitterness identified as very low in one tasting and only moderate in another, but the dominant aspect in the experience.  In the review where bitterness seemed stronger a flavor along the lines of green wood paired with that; in the other review the tea was described more as mild, light in flavor, and floral.  A flavor along the line of hay or mild version of wood was identified in the other set of notes; that would probably correspond, but seems interpreted as different in regards to level of bitterness and related flavor.  Feel seemed full in both review impressions, a bit creamy even, and the character pleasant, with enough sweetness to give the tea good balance, but a mild overall flavor.  A mild floral tone filled in background complexity, just light in tone, and subdued in character, how chrysanthemum or even chamomile can come across.

That cuts out a lot of the specific observations but covers the main themes and impression.  To be clear (and probably to repeat myself) the Bai Hao version didn't seem relatively bitter, as young sheng goes, but it did seem more bitter in the first tasting, and very mild in the second.  The rest of the aspect description generally matched.

All of this might be implying some judgement of bitterness as a bad thing, which doesn't necessarily work.  I made this observation in the first round, related to that:

The bitterness is at a great level; for some people less would always be more, but to me this balances well.  

That aspect seemed more pronounced than in the other tea, and stronger in one tasting than the other (the one this comment came from), but to me bitterness can work really well in sheng if the balance of the rest compliments it well. 

Second tasting session; Bai Hao left, Workshop tea right





Possible reasons for variation


This provides a good background for talking through why reviews might be inconsistent; these two in particular, but also in general.  I'll list individual potential reasons for variation and talk through background more within that format.


I'm not a consistent input:  teas can seem different depending on changes related to the person tasting them; energy level, mood, background conditions changing perspective, etc.  Even though I've tried a lot of teas over a long time and feel I probably have a decent taste-memory I suspect that trying a lot of teas of a certain range shifts an interpretive baseline.  For example, I'd guess that if I'm trying a lot of very mild versions of sheng for weeks that my impression of what is a bitter version would change to including a lot less of that aspect as an input.  Quality level probably also shifts as an expectation; if I'm trying a lot of exceptional tea of any type it would be harder for a version to stand out related to being well above average.  Background noise in particular is a very significant input; finer details related to tea aspects drop out with any degree of distraction as a factor.


Parameter variations:  this could make a big difference.  Shifting proportion or water temperature would change outcome, even if proportion difference was offset by infusion timing change.  Using even slightly cooler water would brew a milder version of tea, related to infusion strength and intensity of both flavor aspects and astringency.  Drinking a tea a good bit slower would actually change water temperature, giving the drained leaves a chance to shed more heat in between infusions.  The water used itself would vary results quite a bit, and using filtered tap water might introduce another potential variable, since mineral levels and proportion really could vary some day to day.


Guesses about this specific case:  I hadn't given it much thought at the time but I brewed the tea inside the first time and drank it outside the second, at a concrete table beside our driveway.  It's nice out there; lots of plants make for a pleasant background.  It was a bit cool both days, for us, but maybe as cool as Bangkok ever gets for the second tasting, around 25 C (77 F, or so).  Right, it's warm here.  I was using a slightly lower proportion the second time, not for any particular reason, but that parameter judgment is usually just based on immediate inclination.  Infusion times would have ran a little longer as a result, to even out brewed tea strength, but it's easy to not really compensate for that difference with the right degree of timing change, and to drink the tea lighter.

I think temperature may have been a factor.  I was drinking the tea in a cooler space, on a concrete table versus wood, which may have drawn more heat out of the teaware, perhaps a bit slower due to having more time.  Proportion probably also came into play.  I suspect I always vary at least a little as an input, in every review.  Sometimes I have a long block of free time for a review, setting up a good baseline for background, but I don't always.  I definitely sleep different amounts every night, more or less interrupted, and review teas on Saturday or Sunday mornings, but at different times in the morning.  That kind of input change should be minor, but minor changes could add up.  If kids are around (and half the time they are) the background noise changes things a lot.  Even expectation of finishing more quickly would be an input; working around having a set length of time.

I doubt the leaves varied, but it's worth at least mentioning.  Plantation tea would be made of very consistent plant material input, and probably processed very consistently.  I doubt the tea itself really did vary though, but it is conceivable.  In cases when it's known that multiple types of plants were used in making the tea it would be more a factor, or when evident processing variation would be a cause (slightly scorched leaves, a case of a processing flaw).  I'm guessing that the tea was probably relatively uniform in this case, not a main cause.


It was an interesting experiment.  I won't be running that too often because it takes a long time to do two tastings and to edit notes for that kind of thing.  It seems a good time to point out that I see these reviews as an impression.  It might be more of an objective take than someone with very limited tea exposure and review practice would pass on but I never intended them as amounting to a final analysis.  To really get to that, a balanced, final opinion, it would help to try a tea at least three times, and compare notes on impression from those three tastings.  Four or five would be even better, perhaps using the last round as an evaluation in comparison to the earlier findings.  

Interpretation of basic aspect levels (eg. bitterness, sweetness, level of astringency) really should be relatively more consistent, but interpretation of flavor aspects would naturally tend to vary.
