I'm comparison tasting a Moychay Jin Xuan green tea with a Viet Sun Lai Chau Deep Forest Green tea (the second from spring of 2026, with the first not listing a date, but probably from this year).
This comparison is really throwing the Moychay tea version to the wolves; I already know the Viet Sun tea is exceptional, from trying earlier forms. It held its own well though.
Moychay sent a number of different samples to try, in part related to me helping with some editing. It's much appreciated; it will be a great chance to try lots of familiar types, and some new ones. Most of it is warmer toned versions, lots of black tea, oolongs, some fermented / hei cha range, even some flavored versions. It makes sense that for a lot of the year in cooler European climate warmer teas would be favored. Not just now, so much, when lighter teas would go better with a heat wave, but it'll be fall again soon, and spring wasn't so long ago.
This is the last tea I have to try from Viet Sun, from the last order (sent as a sample for review; I'd keep buying sheng and black tea from them, if I had included more than a few versions). Green tea is more or less my least favorite category, but the exceptions can be nice, like this one.
One additional thing I wanted to mention: Steve said that their sales were down this year. It's not hard to guess why (not related to teas being unfavorable; they're good): the economy can seem uncertain in lots of places now, and inflation already stresses plenty of people's budgets. I wonder if there aren't other inputs though.
I'm not sure how Moychay's business either expands or flattens out in "the West;" I haven't kept up with hearing about that. This is all supposed to just be about the teas anyway.
I'm also just coming out of a 6 day long illness, I think in decent shape for tasting. I'll lose a little intensity and finer flavor sensitivity to this cold, but it's resolved enough that drinking light teas again makes sense. For those more difficult days it was nice drinking mild black tea, not getting much of the flavor, but appreciating the depth.

Let's check their sales page input for their descriptions, and pricing:
Lai Châu Deep Forest Green Spring 2026 (they're only selling 250 grams for $57.50 now, no other sizes, at 23 cents a gram)
A green tea made from same tea tree varietal as our Lào Cai Deep forest teas but on the Lai Châu side of the mountain range.
The tea trees in this area are growing to heights of 10+ meters in the deep forest at 2200m+ in elevation. The rich biodiversity and natural growing conditions really make their way into the cup.
This tea brews up slowly into a rich, clear golden soup. The flavor is unique and complex. Reminds me of forest flower honey, herbs, strawberry or raspberry and wild grasses with a lot of umami. There are some similarities to Japanese green teas.
Light astringency and bitterness, thick mouthfeel, long rich huigan and relaxing qi.
Another interesting aspect of this tea is the aging potential. I have tried teas from past years and they get sweeter and richer over time. The honey notes become more prominent as well.
Maybe I was thinking of that other origin area green tea from them...
Green Tea Jin Xuan Lü Cha (they only list a 7 gram size for 2 Euros, 33 cents a gram, with the 50 gram size having been sold for 30 cents a gram, when it was available)
Jin Xuan Green Tea is a high-mountain green tea produced from the Jin Xuan oolong cultivar in Sanming City, Fujian Province. Grown at an average altitude of 1100 meters, the tea is cultivated by a sustainable agriculture enterprise, recognized nationally as a green tea production base.
Harvested by hand in April, the tea is picked as one bud with two leaves. Processing follows a traditional green tea method: sun withering, indoor airing, pan-firing (kill-green), rolling, and drying...
...Its fragrance is rich and floral, accompanied by a distinct fresh soybean note. The taste is smooth, refreshing, and sweet, making it particularly enjoyable for daily drinking.
It's interesting considering that both are probably relatively safe tea options. Producers surely aren't pouring fertilizer and pesticide on forest grown teas, and the Jin Xuan is presented as a sustainable production output.
Of course Jin Xuan is #12 in a series of developed cultivars (cross bred plant types) in Taiwan, produced a long time ago there. Rolled oolongs here in Thailand tend to be Jin Xuan, #17 (Ruan Zhi or Bai Lu; kind of a long story about that naming), or maybe Tie Guan Yin or Qing Xin.
Review:
Lai Chau, first infusion: I brewed these quite light to start; I'm not sure why that made sense to me. Flavor is nice, just light. There's a freshness and depth to this, with good floral range and mineral base showing through already. It will work better as a breakdown next round.
Moychay Jin Xuan: it's interesting how much umami this expresses. That might throw off using personal preference as a main marker; I can appreciate how good Japanese teas are, but I like other styles more. This could possibly be as good as the other tea, just much different in style. The other tea expressed some umami, but this includes more. It's a lot better than the Thai versions one might run across here, but that's typically a low bar to clear. The oolongs are better, and most aren't great.
Brightness and freshness relate to the main range you experience, then floral depth and sweetness enters in, with lots of an umami edge. It seems this will balance well, and be quite complex, again easier to describe as a breakdown next round.
Lai Chau #2: lots of intensity; brewing this 6 or so grams for over 10 seconds provides an intense infusion. Floral range is so sweet, rich, and intense that this tastes like perfume smells. You get some vegetal range with that, that's hard to describe, maybe along the line of deep forest fern (like the scent; you don't eat those). After you drink it a strong aftertaste and full feel occurs in the back of your mouth, not just the throat, but the entire rear part. Mineral stands out in that, not light or warm mineral, but mineral with depth, a range of it. It's all quite clean. Maybe a touch of pine bark is there, beyond those described aspects, but that's clean too.
It's complex; it would work to use other descriptions. There is some umami. Floral range is complex; there's a lot one could associate with it, probably as a few notes, or a range of them. One catchy part is rich and deep, like lavender, but there's more to it. Related to vegetal range sugar snap pea sort of applies.
Jin Xuan: that umami hits you first, then such a strong floral input that in some teas you'd think this was altered. But it doesn't work out that flavor-adjusted teas show the added flavor more after the first round; that kind of thing extracts right away. And I don't think it's even possible to add umami like this. This tea is clearly natural, it's just distinctive and unique.
Others could place this in relation to Japanese green tea range better than I can, maybe a specific type of sencha. It's there, with that umami, and rich floral range expression, good intensity, clean nature, good balance, refinement, etc. Aftertaste is sweet and umami range combined. This does hold its own with the other version. Even for living in a country that produces a lot of Jin Xuan cultivar, and trying plenty from Taiwan (typically oolongs though, in both places) this is probably the best green tea version I've tried from that plant type. It would be more impressive if that came up more often, but it's still really good.
In trying the last of the other there's a savory note in it too, but it's more a sun-dried tomato oriented aspect, where this is closer to the seaweed umami, it just doesn't really taste like seaweed.
Lai Chau #3: it falls into a nice balance, with all of those layers and levels combining well. But it's not really different. It's nice the way that a savory sun-dried tomato umami depth ties the rest together, and how it all balances. It's an unusually complex version of green tea.
Jin Xuan: the proportion of those flavors changed, with umami and a specific floral note really standing out. It also expresses depth, complexity, and balance, but those two notes stand out more than the rest.
Lai Chau #4: vegetal range is standing out a little more; in one sense this is already fading, or at least changing, I suppose to be less positive. It still has lots to offer though. Perfume-like floral range is pronounced, and lots of aspects combine together. The feel is still full and rich.
Jin Xuan: maybe it was already transitioning towards this in the last round, but a savory note tastes a lot like toasted rice, like that flavor aspect in Longjing. It's interesting, positioned along with a seaweed oriented umami flavor, and a good bit of rich floral range. That still resembles lavender, to me.
Intensity, depth, and complexity are pronounced in this; it more than holds its own. But as you go back and taste the other tea after even for giving up a little in intensity and range it's still just as pleasant, for those other flavors combining so well. Both are holding up well, but then it is only the fourth round.
They both brewed a couple more really nice infusions, and weren't dead even after that, but I stopped taking notes there.
Conclusions:
I'm surprised that I liked the Moychay Jin Xuan as much as I did, and that it represented that high a quality level. It's one of the better green teas I've tried in a long time, and even people accustomed to better Japanese green tea would probably love it, and also be surprised by it. The dominant umami transitioning to other range made it better for me; the other floral tones and additional complexity worked well. I didn't expect all of that.
But then the Viet Sun deep forest green tea was as good as I remember, very distinctive and pleasant. I suppose due to me liking the flavor aspect range better I did like it better than the other version, but it might work to objectively say that the Jin Xuan version is slightly better quality tea. It was more refined, with both being quite complex, and a little more distinctive in style.
Related to value both are kind of equivalent. The Vietnamese version is selling for 23 cents a gram (at higher volume; equating volume would level out the difference), and the Chinese Jin Xuan for 30, but one already went through import to Europe, which adds cost, and potential value, for people paying different import taxes depending on origin there. Tea as good as either would still be a decent value if selling for more; these were both exceptional.
So the only catch is that I'm a sheng pu'er drinker, and that I like black tea and varying oolong types best as fall-backs. I like novel and pleasant hei cha versions more than green tea, which I can still appreciate, but I just never end up buying it. I had routinely made an exception for Longjing, for years, but now I just stick to those others, and buy mostly sheng, and some black tea.
For people who really do like green tea, and want to explore what these two vendors sell, these are both good options.
