Kokang 2018 Myanmar sheng "pu'er," compared with YS Impression


Yunnan Sourcing 2018 Impression left, Kokang Myanmar dragonball right (2018, I think)








I found a set of sheng pu'er dragonballs I'd misplaced, passed on by the Kokang Myanmar vendor about a year ago (many thanks again for that).  Tying back to the theme of combined tasting, I just saw a post about the 2018 Yunnan Sourcing Impression cake selling out, and thought to try this Myanmar version along with it.

Why that makes sense:  both are from 2018 (I think), but both should be quite different teas, one from Yunnan, designed to be an inexpensive but well-balanced blend, the other made from narrowly sourced local tea (presumably).  So the contrast is the theme, to see if I can tell how much local character differs, along with spotting aspect differences related to a blend and narrowly sourced material.

Shape will throw things off; dragonballs aren't well-loved in tea circles because it takes some messing around getting them to open up.  You can only brew that one quantity, and even then the first few rounds don't match how fast other loose tea from a cake or tuocha saturates and opens up.  A lot of the early rounds tasting is going to relate to looking past infusion strength differences and these being at different places in an infusion cycle.  On to that though, with the usual amount of chatting about tangents.


It's odd that I just took a month off reviewing teas.  It sort of related to the pandemic, and also to running low on tea samples yet to try.  I could write another half dozen posts if I went back through everything, or an endless series with re-tasting as a theme.  I've been trying spare teas on hand that aren't interesting enough to write about, random sheng samples friends passed on, medium quality oolongs, or green teas from here or there.

I've been doing a lot of retasting too; I typically drink a sheng version that I've had around for a year or longer with breakfast, something different every day, with other teas mixed in.  Yesterday I re-tried a Vietnamese sheng version I really liked with breakfast (this one), and went off-script and had a wild plant version Thai sheng with lunch, produced by Kittichai of the Jip Eu shop.  That last tea has evolved to be much more positive since I reviewed it last year, dropping out an odd sourness, and touch of storage mustiness, and picking up floral tone that has somehow shifted over to fallen leaf character over the last two months.  I'll get back to that, passing on those sorts of updates in a review.

I can add a little about this Kokang tea from their website (not this specific version, but in general):

KoKang is one of the six self-administered zone in Myanmar located in northern part of Shan state... 

KoKang area being situated at elevation of 1800 to 2000 meters above sea leave, tea plants grow into century-old, big leaf tea trees since they were left undisturbed and no cultivation. KoKang tea plants are grow in perfect ecological system with no use of pesticides which can harden the soil and degrade the quality of tea leaves. Due to it remote location, poor transportation and special political condition and administrative situation, KoKang was left alone in undeveloped and therefore KoKang teas were left unknown to the world. 


The other teas I've tried from them really were worth checking out.  It's produced quite close to Yunnan, but I agree with the idea that comes up that it's not fair to think of this as "border tea."  It's just not from Yunnan, or China; related but different.  The tradition is older than the modern border; I think this had been part of China at one point, not that long ago.  And to me sheng being from other places gives it an edge for being novel, versus being close enough to the same thing.  Where it is from might be of interest, from their website:





Review:


a somewhat long soak for the dragonball really barely started it brewing


2018 Yunnan Sourcing Impression:  these first 2 or 3 infusions will really be about getting these to even up in a brewing cycle.  I infused this for around 10 seconds, plenty of time to get it started after a rinse, letting the ball sit for longer.  I'll probably use a flash infusion next time, for the Impression, to even out differences, since the dragonball still looks like a ball, only wetted related to outer leaves.  I last re-tasted this first Yunnan Sourcing tea in the last few days, so this will be familiar.

It's nice, a little light, slow to get started but pleasant.  Bitterness is moderate, and an interesting mineral and sort-of-towards-spice tone stands out.  Mineral is like rusted iron pipe, which is probably more pleasant than it sounds.  It would be natural to interpret the other flavor range as closest to cured hardwood, and that's part of it, but it leans towards spice in an interesting way.

To be clear I wouldn't expect anyone trying or reviewing this tea in the US to experience exactly the same character since this has been stored in quite hot and humid conditions here in Bangkok for the past year (related to reviewing this along with the 2017 version a year ago).  Teas transition fast here.  They tend to lose bright, fresh character quickly, which wouldn't be positive for everyone or in all cases, but if a tea (sheng) would've benefited from some transition that happens quick.  It seems to draw out warm tones, comparing changes to what I see in dryer storage versions I buy. 

Malaysian storage can easily include a musty edge, onto slate mineral, or the range of damp basement character, or even geosmin (beet / dirt) over a longer time period.  But to some extent air flow seems to be a critical factor along with storage temperature and humidity, so final effect can vary.  I think sheng stored by the local shop I keep mentioning, Jip Eu, is stored without significant air contact (relatively sealed up), so they tend to be a bit musty right away, which fades nicely over a few months.  All of this is speculation, just guessing, but it is based on experiencing a modest number of teas changing over a few years of time, and trying versions that have been set aside by others for a decade or longer.


2018 Myanmar Kokang sheng:  there's not really enough flavor extracted to say much about this yet.  It seems bright and sweet, with pleasant floral nature, but that could just relate to how a very light brew comes across.  I'll need to tear this apart and give it two more rounds to get a decent read.  To be clear I don't hate dragonballs, as some do, but to me they're not exactly the ideal form for experiencing sheng; they don't brew quite as well.  For moderately above average quality sheng examples it doesn't matter so much, but I get it why people really into optimizing experience could see that as a problem.  These are about the same amounts of tea (8 grams), but it doesn't look like that in the early pictures.

Second infusion:






2018 YS Impression:  I really brewed this for a half-dozen seconds, fast but not a flash infusion.  Bitterness has ramped up but this level works for me; it balances well.  Feel is reasonably full, with flavor complex.  Aftertaste could be more pronounced but it's enough to round out the experience, to add to it.  Flavor range isn't so different than last round:  bitterness stands out, and there is some floral range, and cured wood tone, underlying mineral (with a bit more dry mineral along with the warmer rusted iron in the first round), and a nice hint of a spice range.  I never really did clearly identify what that was in tasting it a few days ago, but then I was "off the clock" as far as even trying goes, just drinking the tea.


2018 Kokang:  a decent hit of smoke joins in this.  From the character I'd guess that will probably fade over the first few infusions.  There's one related smoke flavor aspect that tends to drop out, which I would guess is from charring the leaves in processing, an actual smoke taste, which is how this seems, and another different version of smoke that seems natural to some leaf input.  Again, just guessing.

Bitterness level isn't so different than in the Impression but the character is way different, across all the aspect range.  This is thinner, which probably relates more to it still opening up.  Floral tone is present too, as another primary range.  It seems as well to hold off on more breakdown a round or two until it gets wet.  I did manage to pull apart the outer half of the ball after the last infusion but that means that the inner core of the tea still isn't completely soaked yet, and won't be past a first infusion until the round after next.  The next round might be a good place to describe how that shifts early character differences.


Third infusion:





There is still an inner core of the dragonball, but due to pulling it apart that should get soaked over this next round (the fourth).


Impression:  to me this balances really well.  It's only as good a tea as it is (pretty good, I think, but upper medium), and it's a blend, but for being that it's quite positive, maybe better than it should be for the moderate pricing.  Scott had mentioned in one place the early idea was to create a moderate cost blend to compete with teas like the Dayi 7542 and I think it's better than that, or maybe it's just that I like the character type better.  7542 is barely drinkable to me within 2 years; it's more set up for drinking it as a young version after 3 or 4 years, with better character after 15.  Of course a lot of that has to do with the leaf not being nearly this whole; chopped leaves express more astringency, and come across as more bitter, requiring more aging time to mellow.

The base primary wood tone might not suit everyone, but there is nice floral aspect (a little), and that hint of spice as interesting and positive forward range, and a nice broad mineral base to add complexity.  Moderate and balanced bitterness, good sweetness level, rich feel (relatively), and some trailing aftertaste add to the overall effect.

Out of all that there's something novel about the feel, the way in which that is thick.  Without that cool hint towards a spice note (something along the line of nutmeg, but that probably isn't it) it wouldn't be as interesting, but it would still be positive.  It would be natural for people to interpret the flavor complexity and mild spice range as tied more to a root spice instead, I think.  The woody tones cover both cured hardwood, a richer, deeper range, and the bitterness seems to tie to a tree bud type of experience, a fresh sappy note with a bit of bite.


Kokang:  smoke is still dominant.  Even if that would tend to transition away to other range naturally in this dragonball presentation it's going to take a fourth infusion for all this tea just to start infusion (although the first round hardly counts; it had barely started), so the normal transition cycle is delayed.  Some of the leaf content has had two complete infusions already, so that transition will be inconsistent. 

The tea seems pleasant; it doesn't seem like interesting character and quality is an issue. I think it will pick up a bit of intensity on the next round once it's all brewing.  It shares some of the woody scope with the Impression, but that comes across more as green wood.  Bitterness level might be lower, although it is tricky identifying that apart from infusion strength differences, since changing infusion strength will shift the balance of which aspects you pick up the most.  Flavor comes across well beyond bitterness and astringency even in a lighter version.  Next round should work better for a fuller description, and it will also tell how that smoke effect is going to play out, if it really will drop out.

Fourth infusion:




Impression:  more of the same, really; I'll skip repeating all that.  Nice though.  I'm thinking I notice a bit of fruit, but then I did just eat a banana in between rounds, and someone is eating crackers and strawberry jam beside me, so maybe that's from thinking about fruit.


Kokang:  smoke is fading; it's a minor aspect now, maybe not even something one would pick up without "looking for it."  Mineral is really strong in this, again a much dryer version of it than stood out in the Impression at first, which shifted from warmer range to lighter in that tea too.  Sweetness is good, and a touch of floral range works.  The balance is good.  It comes across as slightly narrower in range than the Impression does, especially covering a little less flavor scope, with good feel structure but one that's less rich.  Level of bitterness isn't high but it's definitely substantial.  I get the sense this is still transitioning to where it will really be over the next two rounds.

It seems pretty good; I'd be open to buying a story about older plants and natural growth related to this.  The narrow-source versus blended tea character (in the other) didn't result in as pronounced a difference as one might expect.  I think this did naturally balance without the mixing that helped the other version, that it wasn't thin across any particular aspect range to begin with.  It was probably just a coincidence that there are as many parallels in the aspects present in both.

Fifth infusion:



Impression:  it's not transitioning fast, not changing to be something else, and the aspects present aren't weakening.  Sometimes an early-rounds bitterness and astringency will ease up over the first 3 or 4 rounds, and to some extent that probably did happen.  It probably is similar but slightly more approachable, which was never a problem anyway.   There's still a nice balance between the mineral range, warm wood tones, lighter floral range, and something hard to place, a lean towards spice.  It might be something along the line of dried tamarind, so really a darker (or warm), unusual fruit tone.


Kokang:  smoke seems slightly more notable than I remember from last round, probably shifting with infusion strength change.  Mineral is really strong, towards flint or limestone, almost leaning a little towards chalk, without that feel.  Vegetal range, only a minor supporting aspect in this, is in between green and warmer cured wood tone, with some vague floral range balancing that out.  All that balances and works better than it might sound.  It's clean, and sweetness and bitterness levels work well.  Flavor intensity is good.  That heavy mineral is characteristic of older plant input, and the moderate bitterness matches how that usually works out, more natural growth.

Later rounds can still tell a story, and a tea transitioning positively across more than a dozen rounds is a good sign for tea quality.  But I get bored making notes, even if those are limited to a half dozen words per series of rounds.  I'll probably taste these one more time and let the writing drop.


Sixth infusion:


Impression:  hanging in there; this is thinning just a little in range but it's still quite pleasant. As I remember from drinking this recently it will retain positive character for plenty of additional rounds but will keep thinning (in aspect range, and thickness of feel), and will pick up woodier tones.  Or the other range will drop back, and wood that's present will show through more, however one sees that.


Kokang:  smoke is quite faded again; strange.  I think the light mineral seems to form a linked range with that, so with minor shift in intensity it can come across different ways.  It would be possible for someone to interpret this wood tone as being more vegetal than I have, to say it leans a little towards kale or green tea.  I see it as more just wood, adjoined by floral tone, which is more dominant in many other sheng versions. 

It's interesting how the intensity of this is really standing out in comparison with the Impression.  Some of that could relate to getting a slower start, to being a couple of rounds behind, but I think it's also part of the natural character.  It covers a slightly narrower range (in flavor and thickness) but expresses a good bit more intensity across that scope.


Later rounds:


I tried a couple of rounds later and didn't take notes, but I can pass on a general impression.  The Impression version seemed closer to aromatic wood than I remembered from earlier, towards cedar or redwood.  That's not bad, just a slightly different interpretation than I'd been repeating, but still quite close.  The Kokang version included a relatively pronounced pine needle aspect; I think that was new, a late-stage flavor transition.  I probably liked that better than the series of aspect ranges that came earlier; it's nice when a tea keeps improving over late rounds.


Conclusions:


I kept considering which tea I liked better.  I do like that Impression cake, and up until the later rounds I probably did like it better.  Right at the end it was fading a bit and the other Myanmar tea was still going through positive transition, so it was better, at that stage.  I'd expect that tea to work out well stretched for a long count of infusions.  The Impression hangs in there; it was just fading a little, and beyond the flavor moving into wood range it keeps brewing.

Maybe overall I liked the Impression better at this point, but I think the Myanmar tea probably has more aging potential.  Maybe brewing both another 3 or 4 rounds would change that (which I'll get to); if the Myanmar tea is just as positive over that many rounds, in a form I like even better now, my overall take on both might be even. 

I don't know why someone would want to keep 8 dragonballs around for a long time, but if they did those would probably keep improving.  They were wrapped in a light foil wrapper under that paper cover so maybe they wouldn't transition fast at all, isolated from air contact that much.  Aging 64 grams of tea packaged to take up a lot of space would seem strange anyway.  That tea is probably better than it was when first produced but I think this is probably a decent time to drink it, at this relatively early stage of changing with age.

It seemed like the Myanmar tea was probably made from really good material.  At a guess the processing worked out to make a quality tea but didn't exactly optimize that potential.  The tea was smoky originally, probably from being charred a bit during the frying step, and just slightly cloudy early on, which could relate to it not drying optimally at the end of processing.  Of course I'm guessing; I don't make tea.  I liked it, and it was interesting, clearly a good version of sheng, so I don't mean all that as criticism of how well it comes across in general.

Chinese tea producers talk about corona virus experience


First posted in TChing.

This title sounds a bit more extensive than the post will be.  I asked a few online friends in China (contacts, if you'd rather) about their experience with this virus issue, and they passed on some thoughts.


it was no time ago we were uncertain of risk but still going out



I'd hoped it would come together better than it did.  It had seemed the human side of the story was getting lost in the first six weeks of reporting on it, and the fear and unusual restrictions within China were special conditions not being considered elsewhere.  As everyone knows the entire country was essentially closed down for a month, then not completely re-opened after.  Then the accounts passed on by contacts in China were mostly just about people missing the normal New Year holiday experience, and being bored in isolation, and concerned.  Economic impact came up; it's hard to imagine how extensive that would be, or how long it would take for full effects to trickle down.  I'll share some input all the same.


as a parent this picture had an impact on me



My good friend Cindy of Wuyi Origin described the general earlier status:

So from 26th [of January] the government took fast action, and did not allowed the  people to gather together, and not go outside. Each village closed the roads in order to protect the village's people.  They did not allow outside people to enter their village. For example Wuyishan has 3 high speed ports (highways?) but the government here closed that.  No one can stop in Wuyishan and enter here from high-speed ports before the 18th  of Feb.


Another contact mentioned how although this sounds extreme he actually approved of it, since that extreme measure was for the benefit of the entire country, and was probably the only way to stop virus transmission effectively.  I'll get back to that other input but wanted to also mention Cindy's take on the impact on the economy.


Several doctors and nurses lost their lives in this incident.  And in China many enterprises face bankruptcy. It is really a big  influence on the economy. In Wuyishan now, 80 percent of the shops are not open [to be clear that was a bit earlier, maybe different now].  All the hotels and  restaurants cannot start the business until the situation is stable.

...One of my cousins invested in a  hotel in Wuyishan.  He invested a lot of his family's savings, and borrowed some from others.  This will cause very poor business for his hotel, like SARS in 2003.  That lasted almost 2 years, then everything went back to normal...


I just saw a FB post warning that business layoffs in the US are likely now from the slow-down of panic, without any remotely similar cause or condition as just occurred in China.  That doesn't make US business problems any less real or valid, just pointing out that a consumer spending slow-down and completely closing down a country for a month are two different kinds of things.

Here's a tea related article on that:  Retail Impact of COVID-19 is Devastating for Tea and Coffee Shops in China and Italy.  This isn't a research post about that topic though; I'll add a bit more first-hand impression.  This more recent input about a return to normal is from Philip of Yiwu Mountain Tea:


I returned to Guangzhou as businesses are officially allowed to open under strict guidelines.  everyone has to wear a face mask.  I was temperature checked 5 times en route.  I have to register electronically and get checked with my WeChat account whenever I arrive at a destination saying where I came from.  At my business I am required to log and temperature check all visitors.

I also hear that there are offshore Chinese going through Thailand as there are no direct flights to Chinese destinations.  Not that I think the risk is very high but then again you never know who is doing what abroad.  The UK has seen a sudden rise in confirmed cases in the last couple of days.


The restrictions could seem like they might not go over well in the US, but we are doing exactly those kinds of things here in Bangkok now, just not consistently, and it's not mandatory (but scaling up).  The security guard at my office checks my temperature sometimes, just not always.  In an earlier discussion comment (from before the re-opening mentioned in that comment) he had mentioned the other issue I'm getting into here, secondary impact, also tied to tea status:


It's been a very quiet month - normally a lot of new year feasting and visiting of distant relatives would be par for the course but this year it's been more sit and chill and try not to think about the worst.  We have elderly with poor health so we have to be extra cautious, especially with hospitals so poorly equipped in this region. 

It's also a case of worries since Spring tea will come soon and visitors may bring in dormant virus late, or nearly as bad,  not come at all and lose income for the year.  That would be a disaster for  cash flow for everyone in the local tea biz. It's also very likely that there will be a shortage of hired labour, and in combination with a very dry year so far,  it's going to another low production year even if people are ready to buy.


I personally am not so worried about paying more for tea, although I am concerned for the health of people everywhere.  Especially in my own family; my wife's mother is in her late 70's, and not in great health, and she matches way too much of the profile of the highest risk cases for this virus.  I'm sure that my wife and kids and I could get it and ride it out but that's not as safe an option for her.  I think my parents could weather it too but hopefully that won't be tested.

Those are just fragments; others said more.  Those comments seemed to capture how this crisis is occurring across more than one dimension, even if they really didn't add much detail to the human cost some have suffered.

People tend to frame this by looking at the number of flu deaths in comparison, which isn't completely unfair (16,000 so far for this flu season).  The mortality rate is the main concern, probably around 2-3% versus .1% for the typical flu (or at close to 4% dividing out confirmed deaths versus confirmed cases, which is surely incomplete per both stats).

a Farmerleaf video on how this will affect tea production, and one on William's quarantine experience



Later update:  a lot has changed in the week since I wrote this initial post draft.  The US is shutting down now, and I've cancelled a family vacation for the end of this month, and a trip back to the US in May for a wedding seems unlikely.  It's too bad; I've not visited my family for a few years.

None of that changes China's experience with the virus from the first two months of this year, but perspective on it seems different, since that's now a shared experience.  This is why I had a problem with the human cost being overlooked there; even beyond the deaths, which are personal tragedies, and related economic impact, it seems wrong to just write off the fear and uncertainty experienced by an entire nation.  I hope this goes better for the entire world than it now seems that it will.

This situation is bad enough but learning more about risks and protection steps helps balance out sensational media reporting.  The Center for Disease Control offers tips for prevention here, and advice on steps to follow if you become sick.  It should help to replace blind fear with taking well-informed steps for protection.

Tea flavor / aroma wheels reconsidered (with a Spanish version)


Early on in my blog history I considered the use of tea flavor or aroma wheels in tea tasting.  My main critique of those related to noticing that the flavor or aroma examples were all from temperate climate or "Western" examples, when that doesn't necessarily reflect a complete range of experienced flavors.

That was back at the end of 2013; what did I know of tasting tea then?  Or now, really.  Some tea reviewers tend to draw on Asian flavor references quite a bit instead (eg. jujube or Chinese date, tropical fruits, herbs more common to Asia or tropical regions), but those are still an exception.


a cool wheel version from a vendor who is no longer active



All the same it's more a starting point reference, a way to break flavor / aroma experience into categories (fruity, floral, earthy, mineral intensive, vegetal, etc.), with examples of what one might experience.  Both of the wheels I cited as an example then contained limited tropical fruit references, to be clear; that one issue wasn't completely one-sided.  It's odd that I'm not seeing bergamot or muscatel on those, now that I think of it.  "Citrus" makes it; maybe it just has to be broken out from that, in the case of the first.

I just ran across a reference of a wheel translated into Spanish by a tea enthusiast and blogger in Mexico, in the "Life Sip by Sip" blog (by Dennis Diaz, a translated version of the Tea Master's original, but as that earlier and unrelated Temple Mountain version shows the forms tend to repeat).  I talked to that blog author three years ago, when working on a post about tea culture in Mexico, but don't remember noticing that.  Or maybe I did; that was three years ago.  I'll add her impression here (automatically translated from a blog post):





Knowing the origin of the tea, infusing it correctly and without haste, as well as drinking it, enjoying the sensations, emotions and feelings that it causes us, leads us to conscious consumption.

When we drink a cup of tea, our senses receive information that is transmitted to the brain in order to be interpreted and translated into unique images about what we are tasting and feelings that, most of the time, are very pleasant.

Regardless of whether you are an expert tea consumer or someone who is just taking their first steps in the exquisite and wonderful world of Camellia Sinensis, the identification of the aromatic notes and the interpretation of these images and feelings generated will enrich the experience.

Maybe it is read [interpreted as?] complicated, but the secret is to be able to look within ourselves for what we feel and remember when having tea...



Limitations and reservations about this approach



I can't settle for myself if it makes a lot of difference, or is even better, to describe the aspects in a tea or not.  I do that in writing reviews, or course, but I enjoy just experiencing a tea without adding any analysis when I'm not reviewing.  Also I tend to appreciate the overall balance of aspects in any given tea, without necessarily focusing on the flavor as a singular main input.  I don't "get" cha qi or body feel aspects to the same extent many describe but a tea that is thin in feel or lacks aftertaste experience range also loses some appeal.

A recurring theme in this blog has been how different people would naturally interpret the same flavors in different ways.  It's hard to pin that down to one clear, representative example.  Another theme I've been noticing (not really related) is how some tea reviewers (bloggers, of course) tend to mention transitions between rounds in teas that sound as if they are really describing a dozen different versions of tea, while others assert that the main flavors remain consistent, with more shift in relative balance than new flavors joining in, with other range continually dropping out.

What to make of all that?  I'm really not sure.  I can't conclude that "it's all subjective," or guess that some people can accurately identify an objectively correct interpretation better.  Maybe it's somewhere in the middle; the patterns really are there, but interpretation plays a significant role.  In one of my favorite posts I asked a few blogger contacts and a tea maker friend for input about how that works out, in this post: "Imagination and subjectivity in tea tasting, with blogger and expert input."

There's probably no need to repeat ideas from there or try to capture patterns described; input on all that varied.  My wine maker friend leaned towards the take that variations in descriptions is not a problem, running counter to what I take to be the more standard general consensus in that field.  But then I took up and quit wine interest a long time ago (and never had got far) maybe that mainstream stance has shifted since.

Input on subjective interpretation from a favorite chocolate blogger in that post was interesting (I've only ever talked to one chocolate blogger; just being weird in that part):


Lisabeth's answer:  Certainly chocolate tasting is subjective to some extent. Everyone tastes food differently, and so will relate the flavours they taste in chocolate to different foods. In the case of Madagascar-origin chocolate, for instance, the chocolate is so clearly fruity that most people will identify that as a flavour in chocolate made from cocoa beans grown in Madagascar. But whether they taste raspberry versus grape or lemon, is a whole other thing. 


That definitely works.  I suppose grape could come across as similar to raspberry in the context of chocolate flavors, and since there really probably are a lot of complex aromatic compounds in the chocolate (as in tea versions) maybe the range of what is being interpreted really is broad.  This subject reminds me of considering what it would take for a machine to be able to "taste" tea in a post.  It does drift into how testing can identify compounds that map to known aromas (or flavors, in one sense of that term), with half that post was about mapping function projects relying on a human taster instead.


a Wikipedia aromatic compounds table; some degree of objective aroma interpretation is justified



Tasting practice and indirect reference of aroma wheels can help.  Scent training kits seem like the next natural step in that progression, but really one might naturally consider what the goals are prior to taking any of those experiential steps.  Or trying out a new approach with no clear goal could still be valid.

Guidance on use of flavor determination in reviews or analysis


In the first draft version of this post it stopped there, with more about why it might not make sense to break out flavors (/ aromas) than about how it could be useful.  If someone wanted to review teas or just write down their own impressions it could make plenty of sense.  I'll add some thoughts on how that might go based on a half dozen years of doing it, broken up by range of what is typically experienced, those standard sections on those wheel.


Floral character:  a lot of tea is floral in flavor, it's just not simple to break that down to distinct flower types, at least for me.  I tend to specify if a floral aspect is light and sweet, like a wildflower, or slightly richer but still light in tone and sweet, like an orchid, or a bit heavier and richer, like lavendar or rose.  Jasmine I'm familiar with since it's around a lot here; that's distinctive.  Beyond that I'm more or less just guessing, or keeping that range of interpretation general.

Fruit:  this can be trickier than it would seem, since this is a really common food range.  Citrus comes up a lot in varying forms, and berry, raisin, and grape can be distinct, but lots of flavors tend to stay a bit vague.  Dried fruit tones are just as common as fresh fruit; dried pear and fresh pear are two different things, for example.  I think I do notice a lot more tropical fruits for eating a lot of them; seems normal enough.  Sun-dried tomato and related savory range can be very pleasant in teas (and I'll get into basic tastes versus aromas in the vegetal part following, since that's really about umami).

Spice:  cinnamon isn't so uncommon, but beyond that these can be hard to identify.  Aromatic spices reminding me of incense tones come up a good bit, or mild, earthy, subtle spices closer to root spices (like ginseng or sassafras).

Vegetal range:  this is probably the easiest range to identify.  Wood tones can vary a lot (cedar versus redwood or fresh hardwood, dark tropical hardwood versus mild coffee or leather tones), but those are all typically placed under "earthy" category instead.  Seaweed can apply almost as a default for Japanese green teas, but really umami is a taste picked up by your tongue, and not a scent based aroma.  It's interesting how the "super-taster" theme would seem to apply more to that scope, since it is usually used in relation to sensor count and sensitivity to tastes versus aromas, and having problems with tastes like bitterness, but the two themes get combined.

Mineral:  this often acts as a base for other flavor range, as I experience it.  It can be very hard to describe because it relates to how different rocks might taste or smell--not necessarily  familiar ground.  I did some desert hiking and rock climbing in earlier life phases and I do end up referring back to that, the smell of different rocks.  Artesian wells (naturally flowing versions) tend to express a specific range that can come up, a sweeter mineral taste.  I sometimes wonder if this isn't more typically a taste versus an aroma, even though it's not exactly within the sodium chloride (table salt) experience of salt range.

Earthy:  it's interesting tasting range outside of food scope, and trying out just about any shu pu'er leads straight there.  Tar or petroleum can actually be pleasant, although fresh asphalt not so much.  Peat can be a more neutral flavor range than it sounds.  Geosmin (like beet or dirt) comes up a lot related to one type of storage conditions environment for aged sheng pu'er.  Forest floor is a useful and common description, but to me it helps to narrow that to a wetter Spring or dryer Fall forest scent range.  That scent would also vary by the type of trees dropping leaves, and descriptions can be more or less detailed and poetic.  I'm not seeing coffee on either of those wheels, and that can come up, either as a light-roasted flavor aspect or closer to the char found in French Roast.

Char / fire:  closer to that last point, some variation of this is primary in many roasted teas, and some that aren't roasted.  Liu Bao tends to taste a little like Chinese barbecue pork, which is in between charcoal, slate, and a savory range flavor.  Tobacco isn't so uncommon, but I tend to think of that as earthy range, not so far from leather.

Sweet:  malt is under "Sweet" in that Temple Mountain wheel (and in the Tea Master's version; that's a good functional approach for that range).  Really malt seems to relate to a soft, sweet flavor like ovaltine or else a more mineral intensive related version in Assam (Indian black tea).


All that is just a starting point; people's experiences and interpretations would vary.   That last category of sweetness, and the umami and mineral cases, bring up the idea that part of flavor experience is taste picked up by the tongue.  It's easy to not notice that distinction in tasting experience, but it can be identified quite clearly by just plugging your nose while tasting.  Trying to review teas with a cold brings up the same theme; all of aroma drops out.

To me sweetness stands out as critical for helping some teas balance properly.  Other flavor range may or may not "work" if a compensating, balanced mix of experience isn't present, and in general more sweetness works better for supporting the rest.  Or maybe that just relates to my own sugar addiction.

Bitterness is an odd special case as tastes go, most common in young (new) sheng pu'er.  Per my own experience almost any presence of that aspect is negative, until you acclimate to it, and then after that it can be perceived as positive.  Experience would definitely vary tied to personal subjective preference related to that, even more so than for any other aspect range, even though it's really all a bit subjective.

One last point:  if I keep saying that taste / flavor / overall effect preferences are subjective why does it continually come up that reviews or descriptions are presented as objective?  I think there are multiple parts to that.

Common convention could lead to a form of objectivity; shared subjective agreement.  I just went through a long discussion of how Dan Cong versions are most typically lightly oxidized (relatively speaking, in relation to other oolong range), and low to medium level roasted, less so than Wuyi Yancha versions tend to be, because that's widely regarded as an optimum for the tea type potential.  I'll skip the rest of that discussion and leave off here as if that's actually made the point it barely brings up: a 'best" range can be established by convention.

Trueness-to-type is really related but slightly different; matching a style for a specific tea version and positive aspects for that type isn't exactly about personal likes, or those shared by a group.  As an example, high mountain Taiwanese oolong really should be intense in flavor, with pronounced floral range and underlying mineral (a specific form of that), rich in feel, with an extended aftertaste experience.  Someone might love or not like creaminess comparable to milk or butter in Jin Xuan (cultivar) based versions, but it's typical for that tea plant type.

Neither of these scopes are going to be clear based on just trying a single tea; identifying them would require exposure to group norms (in the first case) or other tea-type examples regarded as ideal versions.  Individual preferences can still vary in any number of ways but both these contexts set up groundwork for more objective forms of interpretation.


Postscript addition, related to coffee:



Peter Jones, a manager at the Boulder Trident Bookesellers and Cafe (coffee and tea shop), and a tea and coffee enthusiast, mentioned how this relates to coffee tasting and terminology development in a Facebook group post comment.  He only scratched the surface there, but as one might expect coffee is a bit further ahead related to use of standard terminology, tasting approach, tasting process documentation, etc.  Wine tasting surely is further along too; tea enthusiasts and professionals get it that some parts of the tea tradition are very old and developed and others, the more Western-facing aspects, are younger, still being worked out.

I won't run through a long tangent about coffee tasting here, or how that related background goes.  I'll mention an interesting article on that (A Guide to the Coffee Taster's Flavor Wheel), and include an image of a more recent version of one, what I take to be the current standard version:






According to a Specialty Coffee Association background reference use of images of that wheel is open but also restricted:

The Coffee Taster's Flavor Wheel by SCA and WCR (©2016) is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License


Anyway, that file version was from here, with a little more background in that article.  The previous wheel version, discussed in that guide to wheel use article cited earlier, included a separate wheel that added a second complete version covering common flaws in coffee.  Just great! 

There's no short take on how these references are more developed and functional than the tea versions; it seems a terribly long and involved subject.  This World Coffee Research link (the other organization that developed that new version) leads to more background, if it is of interest.  Or this SCA article says just a little about use, which might be general enough that it's still of interest to people tasting other things, like wine, or tea.
