Thai Ancient Tree and Ruan Zhi black teas


I'm comparing three samples of black teas I've just purchased from Tea Side.  Last year I bought a few Dian Hong from Farmerleaf so in a sense this works as a follow-up, tasting comparable Thai versions.  Only two of the three are made from Assamica plant types, and not exactly in the Yunnan style similar to Dian Hong (more on that after the review section), and the third is a Ruan Zhi based black tea instead.  That's a cultivar similar to Jin Xuan, just different in nature, the #17 instead of #12 in that Taiwanese developed and cataloged cultivar series.


Per some reliable input the name for that plant type probably should be Bai Lu, and the more conventional designation in Thailand as Ruan Zhi isn't actually right.  Or really that was confusing, since vendors often mixing a number designation and a name that didn't match always made it impossible to know which one it was, which label is right, and Tea Side (the vendor) hasn't actually called this #17. I'm making that connection because those are the two main oolong plant types grown in Thailand, which also get used for making black tea, but it's much less common seeing Ruan Zhi (or Bai Lu / #17) based black teas than Jin Xuan.  Per that prior research Ruan Zhi was more of a category name, a more general designation that was either tied to an original plant or to a grouping of plants instead.  Here's the post that goes through that, and that related idea:


Ruǎn Zhī is the predecessor group of tea plants that Qīng Xīn Wūlóng came from. It is a bit problematic referring to it (or Qīng Xīn in some cases) as a cultivar, as that word should be exclusively applied to clonal plants while Ruǎn Zhī has been established and spread through seed, with  the derived Qīng Xīn also sometimes being spread by seed. Neither have an assigned Táichá number, because even if Qīng Xīn essentially was borne out of the Fujian Ruǎn Zhī seed stock in Taiwan it is not a registered clone.

TTES No. 17 'Báilù' ('Egret') is a true registered cultivar - note the use of single quotes - established in 1983...




a lot to take in, with more to read up on in the original source


Qing Xin is the main original plant type used in Taiwan for oolongs (or Chin Shin, as transliterated in that table), at least per my understanding.  At any rate I'd expect this tea to be made in a Taiwanese style instead of as a Yunnan tea, and since it is Camellia Sinensis variety Sinensis instead of an Assamica plant that will also change things.  It's the only tea of the three I've already been drinking, so I already know how it is.  It is like Taiwanese black tea, similar to what gets sold as honey black (typically produced from Jin Xuan, unless I've got that wrong), but it's different.  The review will cover all that, so onto it.

Review


The three teas look quite different and brew to much different colors.  I won't say much about that--the pictures describe it--and just move onto tasting.  I could pick up variations in dry leaf scent too but since brewed tea flavors can vary a good bit from that for comparison reviews that are going to run long I skip making notes on that part too.  As for methodology I'm using water just a bit below boiling point, roughly 95 C / a bit over 200 F, and a probably a bit more than optimum for the gaiwans, typical for proportioning for different tea types.


Ruan Zhi:  the tea is nice; rich, sweet, and complex.  It's generally fruity with a dark earth range of flavors mixed in, along the lines of sweet dark cherry with leather.  I suppose some of that fruit one might describe as another dried fruit, mandarin orange peel, or a bit towards tamarind.  The earthiness could be described in different ways too, or as trailing into cinnamon spice, with cocoa also standing out.  It all works.  The feel might be just a little thin, but then that's how similar Taiwanese style blacks tend to come across too, as very positive in flavor and thin in texture and finish.  They don't tend to last long either, producing a few infusions (or a couple, made in a truer Western style), then fading out.


2017 Black tea from ancient trees number 6 (maybe as well to just use that year or number):  this tea is intense, brewed a little strong using the same parameters.  I often go with a short infusion when brewing black teas or other types Gongfu style but went the other way with that this time, letting it brew for well over 30 seconds to get a full strength infusion, and for this tea at that proportion that was too long.  It not only got wet to start infusing it also overbrewed a little.  It probably does make sense to use a rinse for these teas instead of a long first infusion anyway, I just tend to mix up the approach.  It's always opposites day in this blog, versus shooting for optimization.

It has a somewhat similar dark cherry aspect that stands out in it; interesting it worked out that way, that a main flavor aspect matched.  And someone might describe this earthiness as leather, but it's relatively different.  The first would resemble a clean, bright, sweet scent of a hand-bag or expensive jacket, and this is closer to a bomber jacket or baseball glove.  It has an unusual dryness to it, which does work.  One layer of aspects is not far off coffee; that's different.  In this case I mean a very light roast, that cocoa-range coffees can express, not French roast char, which is a lot more common in roasted teas.  Or that could just be interpreted as cocoa.  Brewed just a little lighter this balance is going to work better; the intensity is a bit much with the way the feel works, and the flavors are dialed up too much.  It's just a little sour; that might throw off a positive impression a little.  It's good tea too though; no doubt about that.


2016 ancient tree medium oxidized number 1:  very different than the other two, but with some overlap.  Fruit is a common ground for all three, which works really well for me since I love different forms of fruit in teas.  For someone else they might hate these teas for that; funny how preference really could vary.  This infusion strength is pretty good; it works.  It has a touch of dryness too, and a similar pairing of fruit towards dried cherry / tamarind with underlying cocoa / leather / aged hardwood, but comes across quite differently related to balance of aspects and different feel.  It feels smooth and a bit juicy compared the previous one being full and a bit dry.  That fruit is quite different, even though it does overlap; I'll have another go at describing it next round.

That "medium oxidized" part in the vendor description probably did play a role in how this tea came across, but throughout these notes the importance of that doesn't stand out, and I don't get around to saying anything about it.  The earlier 2017 version brewed leaf looks lighter, but the brewed tea liquid is a lot darker, and again I'll not try to make too much of those differences.  The first and third teas in this round didn't come across as overbrewed, just prepared slightly strong, but the second did.


that first round; brewed a bit long, especially for the 2017 version (middle)


Second infusion


Ruan Zhi:  not a lot of development or transition, but it does brew another positive infusion using a very short brew time, around 15 seconds.  It's fruity, but really that cocoa / cinnamon aspect stands out most, and then a fruit (dark cherry, mostly, which could be interpreted differently), then the earthier layers supporting that.  The feel is still a little thin but the aftertaste picks up a little, giving an impression of more depth.  I do like the way that flavor set works.  It's not far off how Jin Xuan blacks come across but maybe a little more complex for flavor range, but then those can vary.  I suppose it's heavier on cocoa and spice than most of what I've tried for Thai Jin Xuan black tea versions, which are more fruity, but Taiwanese versions can be like this.  There's just a touch of balsa wood type mustiness, which can be a negative factor in some Taiwanese black teas (unless that unusual range seems positive to someone, then it's a positive one).  It doesn't stand out though, and for me it works in combination with the rest, more giving it complexity than throwing it off.


2017 ancient tree:  it's much nicer just a little lighter, and the flavor / effect is "cleaning up" some.  The sourness drops off and the feel gains some juiciness, not quite as full in a way that contributes a bit of dry feel.  A flavors list won't do this tea justice for catching the overall complexity and intensity.  Another tea could be almost exactly the same in what it expresses but lack this level of intensity, and not have the same effect.  That list:  sweetness, fruit (dark cherry, to me), cocoa, leather, a touch of coffee.  In talking about that dry feel what I mean is the way a lightly brewed, lightly roasted, good version of coffee comes across.

The structure (in the sense of feel) is different in coffee than for tea, and this leans towards that.  But the feel is full, the aftertaste experience is fine, and the flavor intensity and range is good, so the overall effect if very nice.  That last part, the flavor range, is interesting.  That sweet dried fruit gives it an interesting higher note and a clean version of earthiness a good base, with some cocoa in between, so it covers a lot of ground.  There's even a trace of what someone might see as mild mint developing.  That bit of sourness faded quite a bit, and I'd expect given that transition difference it won't be noticeable in the next round at all.


2016 ancient tree:  this is transitioning, the most of the three, beyond that dry texture and touch of sourness dropping out of the 2017 version.  The fruit has diminished and it's picking up a woody aspect, swapping out some range closer to cocoa and leather for that.  The tea can't be finishing up yet; it's hardly getting started.  It will be interesting to see where that leads though.  It lends it an interesting character since it starts to resemble malt more too, but it's lighter and less intense than the other two now.  I'd expect it to last a lot longer related to overall intensity than the first but not the second.  We'll see.  In going back and trying the three again, the last of the cups, I think this tea might've seemed less intense for trying it just after the 2017 version.  It's normal in flavor intensity, but that 2017 one before it was unusual for the high level of intensity.

same order.  the color difference is interesting.


Third infusion


Ruan Zhi:  more of the same from the last infusion, based on using relatively short infusion times, not quite 15 seconds.  If anything that same balance of flavors is working even better now, adjusting to an evenness that really works.  Fruit balances spice and clean earthiness, the same aspects I won't run through describing again.  Again the texture is a little thin but the aftertaste compensates for that.  I don't mean it has significant aftertaste in comparison with good young sheng or high mountain Taiwanese oolong, of course.  A few seconds after drinking the tea the flavor is still there, and thirty seconds later it's still tapering off.  With intense young sheng just after drinking it the flavor can seem to strengthen, stronger than when it was actually in your mouth, and minutes later it might not diminish all that much.  It still gives an impression of a more complex experience as it is.


2017:  this tea's balance really fell together; that intense, structured feel softened and isn't dry, and the sourness is gone.  It has lots more flavor (in terms of both intensity and range), more thickness of feel, and more aftertaste effect than the Ruan Zhi.  That Ruan Zhi is a nice black tea but this is on a different level.  These teas weren't presented as being close to Dian Hong in style (typical Yunnan black tea) but since they are from Assamica plants from a nearby region I'll mention some comparison.  It's not as if a Dian Hong style black couldn't be more complex and intense, beyond just being different in lots of ways, but this character works well for me.  The flavor range varies a good bit in those so to me saying it's typical or not typical of a Dian Hong is problematic.  Some really are like this.  Or it seems possible there are conventions about what should or shouldn't be called "Dian Hong" from Yunnan that aren't clearly identified or adhered to by a lot of producers and vendors.

That reminds me; what I've been describing as dark cherry really could be interpreted as roasted sweet potato instead, just a sweet, clean version of one.  It probably is closer to that, at least in this round for this tea.  It's not like roasted yam, it doesn't seem to me, not that rich, softer, "deeper" flavor complexity towards pumpkin range, more the light, sweeter part.  I think the cherry might have worked better as a description in the earlier rounds, and it's moving towards this now, with the whole cocoa / leather layer thinning a bit.


2016:  this transitions too.  Roasted sweet potato works as a description for this too, just not as well.  The cocoa and cinnamon effect is picking up relative strength instead of dropping back.  In part due to going with lighter infusions the leather and earthiness is more subdued in all of these; simply brewing the teas stronger would make that stand out more.  The lighter, sweeter, more subtle fruit, spice, and roasted root vegetable range would increase in strength more but the proportion would shift how that's perceived, with a different feel mixing with and varying taste experience.  All that makes you wonder if I'm just making all this up, to some extent, doesn't it?  That last part did start in on some guessing.

This third tea could be brewed a little stronger to be ideal.  It works well as I'm making it but it's less intense than the other two.  Did two years of aging give it more depth and a cleaner effect at the cost of dropping intensity a little, shifting some fruit to spice?  Who knows.  I think personal preference would dictate which of these three is better.  The last two are a lot more interesting to me, and seem more complex.  I suppose I like the second the best, but some aspect range others wouldn't necessarily like, especially that bit of dryness and sourness in the first two infusions, which this 2016 version didn't express.  It would be possible to get this third tea to draw more even with the second in terms of intensity just by brewing it slightly longer, not doubling time to compensate for it being a weaker tea, just adding some seconds to adjust that.  I think the overall range of the second would still be broader though; it has a lot going on.  Judging by the first two infusions it probably wasn't as good as the other two but judging by this last one I see it as the best of the three.


this was around a 15 second infusion, on the moderate side but still dark


Fourth infusion:


Ruan Zhi:  this tea might well be thinning a bit now.  I gave those around a 25 to 30 second infusion, so not really lengthened a lot yet to account for losing intensity but some.  I am using a high proportion of tea and all those other infusion times were limited, after going a bit long on the first one.  The same aspects are there, nice sweetness, cocoa and cinnamon spice standing out, but it's diminishing.


2017:  the flavor is shifting a little, some of that sweet potato transitioning to catchy flavor that's hard to isolate.  It's more towards a dark toffee, but the flavor includes different version of dried fruit, a little like a dried mango or dried papaya, but "darker."  I bet there is some dried fruit out there this closely resembles but I'll probably not get to making that connection.  Dried papaya is as close as I'll get, or to connect that with something a Western audience was more likely to try towards date, but not quite that earthy.


2016:  the balance seems similar to the last round in the this third tea.  The balanced complexity works; it covers plenty of range.  One part reminds me a little of the mild mint in teaberry, which was part of what was going on in the 2017 version earlier, I think.  You can eat those "berries," from teaberries, but I don't think they're actually really berries.  And I've read you can dry and brew the leaves, and that they'll even oxidize, if you could manage to bruise them.  If any readers have experience with this I'd like to hear of it.


All of these teas would probably benefit from increasing the infusion time to 40 seconds or so.  It would've worked better to split that first infusion into two, so I'd be on the fifth round now.  The teas aren't fading yet (or maybe just the first one is), but they need longer times to keep up intensity.  Assamica based black teas generally seem to last longer, and they tend to produce positive infusions even when you need to run out steep times to longer to get more out of them.  In a Western style brewing cycle that might relate to getting a third infusion instead, depending on proportion used, and letting them soak awhile.  Experimenting with transitioning from slightly cooler water to hotter water later on is interesting too, but to me just using water a bit off boiling point (95 C / 200 F range) works just as well, and keeps things simpler.  Of course if messing around and noticing variation is the idea simpler isn't necessarily better.

Fifth infusion:


I went over 30 seconds for this infusion but elected to check what they have left for intensity and drink a slightly weaker round instead of running it out to closer to a minute to get a stronger version.  I'm just going to add some thoughts instead of detailed review, and these will brew a couple more infusions at longer times.

The Ruan Zhi is still nice, just thinning.  Again longer times would compensate for that.  The flavor profile is still nice, that cocoa / cinnamon range, it's just narrowing slightly.  It is interesting the way a touch of balsa wood base more or less dropped back; those longer times might bring that out more again.

The other two are pretty much where they were in the last round.  Using longer times in late cycles shifts aspects in different ways, in lots of cases drawing out more of a wood tone, and changing feel, but I don't necessarily see that as part of the main experience of a tea.  It's nice when the last two or three longer infusions stay really positive, versus not so nice, and these will be fine.  The overall intensity of the 2016 version is now even with the 2017; funny how that one tea seemed to brew faster through a lot of that cycle, how it was more intense at the same brewing time, beyond covering a slightly broader range.

Conclusions



not even the whole Tea Side selection; there are six more black teas, and lots of oolong and pu'er-like versions



So I was trying a 2016 Old Trees Black Tea Medium Oxidized, the first tea on the top left, and the second from the left on the bottom.  Why didn't I order Dian Hong style black teas instead?  The Tea Side owner included some tea samples; maybe I will get back with a review of one or more versions of those.


Dian Hong vary a lot in character, and assessing quality level and trueness to type are two different things.  It would be difficult to summarize if these teas were as good as better than most Yunnan blacks, or if it matched that broad range of style and aspect sets as well.  Related to aspects, Dian Hong often go further with including a roasted yam aspect instead, and one I've tried not too long ago expressed a lot more cocoa than these, and general intensity (one of the best Dian Hong versions I've tried, just not one that's commercially available, as far as I know).  At a guess if you'd buy a similar Yunnan black tea from a US based reseller for the same price you wouldn't get tea this good. 


I can't place them related to those Farmerleaf versions I reviewed last year from memory; it's too much to reach back to that.  They could be roughly on the same level but it doesn't work to guess out if they're slightly better or slightly worse.  As I recall I might've liked the black that wasn't sun-dried from them a little better initially, but not their sun-dried tea, and then when I tried it a year later, after it had aged a year and transitioned, I liked that tea more than I did initially.  Given my limited memory take that for what it's worth.


I noticed the Tea DB bloggers reviewed one of the 2016 Dian Hong versions recently.  It would be interesting to critique their assessment but since I'm trying different tea versions--here, at least--I can't.  But the Tea Side owner mentioned something about general character in a comment to that video:


This black tea is made of material from trees 300-500 year old. Such material has a rather pu-erh character. Most of the Yunnan Dianhongs are sweeter, vanilla-floral, because they are made from bushes. Tea from ancient trees has a more modest organoleptic, but deep taste, a long aftertaste (as you noted) and powerful energy (Cha Qi). That is, it is such a "red pu-erh", if I may say so.


Interesting; that could work for description for these, but I'm guessing the character should be different.  Only some of the teas listed specified being sun-dried, and it didn't say for these, but that is a main distinction that changes character in Yunnan black teas.  Sun-dried versions are said to age better, to actually improve, and the same claim isn't usually made of oven dried versions.

That quote kind of maps onto a lot of what I said about the Ruan Zhi version, about that having a pronounced, intense flavor but giving up a lot in terms of texture and complexity.  I'd been attributing that to the plant type difference but maybe it related to the growing condition and plant age differences too, with potential processing differences left a bit open ended.  In the end it's about the experienced tea anyway, not making a study of why it landed where it did.

In trying sheng versions--which I won't say too much about, since so many factors tend to mix--I've been noticing patterns of more wild-grown trees coming across quite differently, being more subtle in nature, and just different in aspect range, earthier, more complex, but not as intense related to astringency, sometimes towards mild spice instead of or along with floral aspects.  Plant age seems to tie to a different sort of intensity difference; sheng from truly old tree sources has a completely different feel, and more aftertaste.  It's not an aspect I value or tend to notice as much as others but the "qi" or physiological effect from older tree plants does seem greater too.  I didn't notice the same degree of effect as when comparing gushu sheng a week or so ago.  Since these are black teas instead comparing across types might be of limited value but some general trends do seem to match up.


For expressing very positive but limited range flavor intensity in one limited sense the Ruan Zhi stood out as best among the three, to me, but to be clear it was my least favorite.  For overall complexity and character the other two were better, and the 2017 matched my preference better, but then they were also just different.  For judging by the first two infusions the 2016 was much better, which would have mapped onto three light infusions instead.

These were interesting, good teas.  It will be nice drinking more of them to mess around with parameters and enjoy the experience without taking notes.  If there were other black tea samples sent with them (and I think there were) it will be interesting seeing how those vary too.

  1. As I see, the both names (Ruan Zhi and Bai Lu) of TRES #17 cultivar are used.
    The main thing is not to confuse it with tea Qin Xin ("green heart" or "green center") oolong bush.
    Qin Xin is an endemic cultivar but TRES #17 is hybrid.

    TRES #17 = Tainon-335 (TW) x Tainon-1958 (TW) = (Dah-Yeh-Oolong (TW) x Kyang(IN)) x (Hann-Koou line(CN) x Bair-Mau-Hour(TW))

    That is, it is a hybrid of endemic cultivars from Taiwan, China and India.
    But Qin Xin even does not participate in this hybrid.
