(7) 2008 Takamado Kabusecha

Great thanks to readers who are enduring this Japanese tea marathon. We are done with sencha / shincha for now but a few more reviews are pending for other tea types. Here’s one that you don’t see often: kabusecha. Tea geeks will know it’s a style midway between sencha and gyokuro: the tea trees are shaded during the last stage of vegetation but for a shorter period than real gyokuro (days instead of months). The result is a tea that’s heftier than gyokuro but having less catechins, is less grassy and pungent than sencha. An intermediate style that’s rarely seen on sale, it is a by-product of gyokuro for some, and a distinctive tea category for others.


Marukyu-Koyamaen are selling this 2008 Takamado Kabusecha for ¥1,100 / 90g can. The dry leaf has that nice dark green colour of good quality Japanese green tea, with a bit more fragmentation than in the recently reviewed sencha from Marukyu. It’s actually looking more like gyokuro than sencha to my taste, though the leaves are larger. The aroma is quite distinctive. There’s none of the intense sweet fruit of sencha, instead the profile is very vegetal (almost spicy) ranging from olive oil to spinach.

Infusion no. 1 (60 seconds at 70C): a light colour typical of a low-steamed [asamushi] tea.

We find the latter scent again in the infused leaves: boiled spinach. Brewed sencha style (2g of leaf / water @ 70C / 1 minute steep) the flavour register is consistent with the leaf aroma: very green and vegetal, without the top citrusy notes of sencha, and not exactly ‘milder’ as people often define kabusecha. A bit of kick on the finish. Good length and an overall impression of cleanliness and very good leaf material. There’s very little bitterness even when brewed at higher temperatures, although it’s really a simple tea with no great depth.

Spent leaves show low steaming and good quality: whole and wholish leaves, no fannings.

I’ve juggled a bit with the variables here. Kabusecha being mid-way into gyokuro territory, you’re naturally tempted to brew it like the latter. While there’s reasonable texture and a kiss of umami to be obtained, this tea just lacks the guts to benefit much from higher dosage and longer infusions. On the other hand, brewing at 80C and 2–3 minutes results in a pervasive seaweedy vegetality and an almost matcha-like powderiness that shows a bit of 2008 staleness, so I don’t recommend that. It’s at its most satisfying and distinctive brewed as in the tasting note above. And it’s one tea that IMHO benefits most from a Tokoname kyusu pot, with the rough vegetal edges rounded off a bit and some extra creaminess to the texture added.

As mentioned, this is a simple, one-dimensional tea with not a lot of content, plus it’s clearly going down as a 2008. That being said, it is very good quality as all Marukyu offerings IME, is really inexpensive, and makes a fine change from your daily sencha.

(6) 2009 Shuei Shincha

OK, so here’s the last sencha review for this year. Yes, it’s another tea from Marukyu-Koyamaen, and my notes will sound repetitive again – let’s hope they can also be useful. As well as provide some dramatic crescendo to my mini-series, as this is by a margin the best Japanese tea I’ve tasted from this new season.

The 2009 Shincha Shuei is a competition grade tea – but more knowledgeable readers will have to enlighten me as to the status of the ‘All-Japan Competitive Tea Exhibition’. In any case it’s among the more expensive offerings from Marukyu but at ¥2,600 / 100g it’s hardly exorbitant.

The good people at Marukyu seem to have a preference for asamushi [short-steamed] teas. This is another very well-presented tea with intact leaves of a consistent dark emerald green colour, no fragmentation, no fannings. Visually it is similar to the 2009 Shigaraki and 2009 Uji Gold from the same merchant I’ve reviewed before. However there is a mild variation introduced in the aroma. This tea smells almost erotic – it is so intense, sweet and creamy, full and vegetal while staying really elegant. Smelling the freshly opened can is almost as satisfying as a proper brewing session. In the background there is some very pleasant baked bread light roast.

A standard session with 2g / 100ml, water at 70C and 60 seconds for the first infusion reveals a tea that is both typical and excitingly good. The colour is medium light with as many shades of green as of gold. Flavour-wise this is eminently fresh and has so much presence and subdued, understated intensity. The concentration of a cup of tea is largely a factor of your brewing parameters but what I define as ‘presence’ is derived from the leaf quality. I rarely wax lyrical but this shincha has a haunting finesse that makes the ‘liquid jade’ metaphor sound very adequate. The leafy, spinach-like vegetality of this tea (usual in any sencha) is subordinated to its evocative character of ripe summer fruits and flowers; for me, this is the hallmark of a truly exciting tea.

First infusion with ‘standard parameters’: 2g, 70C, 60s.

In my previous post on the 2009 Uji Gold from Marukyu I mentioned that with this low-steamed category of Japanese sencha green tea, in order to boost the flavour of your infusion, you have two options to depart from the ‘standard’ sencha brewing parameters: increasing leaf dosage and/or water temperature. Applying these with discrimination, you will obtain more body and flavour without extracting too much bitterness from the leaves. (Grassy, tangy bitterness and ‘fishy’ flavours are a reason why Japanese teas – a large portion of which is long-steamed, fukamushi – are usually steeped briefly from a small dosage of leaves). With this very high-quality Shuei tea, I came up with another solution.

I’ll call it gyokuro technique’, in that it consists of treating sencha tea [made from leaves grown in full sun] a bit like gyokuro [a different grade of Japanese tea made from leaves that are shaded]. In my experiment I increased dosage to 4.5g of leaf / 100ml of water and increased steeping time to 2 minutes, but lowered the water temperature to 55C. In this way, extraction of colour, flavour and nutrients from the tea is changed into a ‘softer’ but ‘deeper’ one. The colour becomes a little more intense but keeps the same greenish-golden register. The aroma is a little more intense too, but again doesn’t change substantially. The major change affects the texture. The tea becomes really thick with a glutinous, oily feel to it, and there is a very distinctive brothy, salty character that is defined as umami [the fifth taste; see more about it in this post], although it’s a little more salt-driven than umami is usually considered to be. (When discussing the concept, I’m often told I should identify it as a flavour impression independent of saltiness).

The distinctive salinity of this 2009 Shuei shincha reminded me of a great mineral white wine from such places as Cinqueterre in Italy or Santorini in Greece. Its eminent quality is also confirmed when you brew it the wrong way. Heavily overbrewed with 85C water, this is shown packing in some considerable power for asamushi, but the bitterness it develops is clean and excitingly fruit-flavoured. Whereas the similarly profiled Shigaraki Shincha from Marukyu was a very tasty but eminently simple tea this has a lot of dimension. Is it three times better as the price would suggest? No. Would I buy it again at the same price? Very definitely so.

(5) 2009 Uji Gold Shincha

Back to fresh 2009 shincha with this Uji Gold from Marukyu-Koyamaen. This is a limited production tea that’s not even advertised on their website, and only sold for a few weeks beginning in mid-May (I don’t think it’s available anymore). At ¥3,200 / 100g it’s among the more expensive sencha teas from this merchant. And as usually with Marukyu, it’s beautifully packaged:

Package aside, the dry leaves are a joy to look at:
We are on totally different territory than the trio of O-Cha releases reviewed in the last few days (see links at top of post). This is very definitely an asamushi [short-steamed] tea, and the leaves are impeccable, dark emerald in colour, 100% intact, almost exclusively whole. It’s a rare sight among Japanese teas. It has an enjoyable aroma, rather light and elegant, sweet (melon), ungrassy but vaguely reminiscent of spinach, very lightly roasted; compared to the other 2009 shincha teas reviewed in this series, this Uji Gold introduces a sweet-spicy note of vanilla.
The dry leaf tells a lot about this tea’s characteristics and pretty much preannounces the ups and downs of actually brewing it. As much as I am aesthetically admirative of the leaf quality here, it’s a difficult tea to interpret. It has little to do with Japanese sencha as we know it. Brewed with standard parameters (2g / 120ml / water at 70C / 60–90 seconds) this yields a light greenish-golden colour, and the profile is very close to a continental Chinese green tea. Light-bodied, unpungent, vegetal (in the sense of green beans and spinach, not the more usual grass), with little fruit (melon); only a very minor reminiscence of brothy umami. This profile continues through the second brewing (where Japanese greens usually pack in more oomph). Perhaps a bit of creaminess to the texture (egg custard).

Infusion no. 1: 60 seconds at 70C.

Logically for a whole leaf tea, where the leaf surface to water ratio is far larger than in a fragmented leaf fukamushi [long-steamed] tea such as this, it’s reasonable to increase leaf quantity, water temperature, or both in order to get better extraction and more depth of flavour. From these options, a higher 80–85C temperature is fine, with more palate presence and length (but a finish that’s bit hard), but I’ve been happier with a higher dosage. Move from 2 to 4 grams of dry leaf in the pot (60 seconds for the first brewing, shorter afterwards) and you’re getting a totally different animal. Deeper in colour (though still yellowish rather than jade-green), much more saline and mineral, this reminded me of some avant-garde white wines from Alsace or Friuli in its full terroir presence. I’m interpreting this as a signature of Uji, Japan’s most renowned tea growing location. Still not exactly a typical Japanese sencha, again reminiscent of something more continental, but now a really exciting tea.

As it stands, I found this an eye-opener. Too often we are stuck with what we deem is ‘typical’: an important concept in interpreting any agricultural product but dangerous when it starts to handicap truly individual ones. This 2009 Uji Gold is precisely that: a high-quality product with a distinctive style. I’m sorry to see my 50g pack drawing to an inevitable end.

No mistake: this is Japanese shincha.

Japanese fortnight (4): 2008 Miyabi Sencha

When I was ordering new shincha teas from O-Cha back in April, one tea that really interested me was unavailable from the 2009 vintage, so I decided to take some 2008. After all, O-Cha proudly state that all their teas are sent out in nitrogen-filled packages, which should effectively prolong shelf life well into the new year. So here is the 2008 Miyabi Sencha.

O-Cha consider this one of their best offerings. Unlike the Yutakamidori and Fukamushi Supreme that I’ve reviewed earlier (see links at top of page), this tea is from Uji, perhaps Japan’s most prestigious tea-growing appellation. At $26 per 100g, it surely has a prestigious price tag.

It’s interesting how I disagree with this vendor’s product descriptions. The 2009 Yutakamidori is described as heavy-steamed and this Miyabi as medium-steamed, yet there’s no doubt the latter sees heavier steaming. While the Yutakamidori, to me, is chumushi (click link at top of page to see a picture of spent leaves: there is a mixture of heavily fragmented and nearly intact that I find characteristic of medium steaming), the Miyabi is a finer fragmented tea, and it also shows in the infusion:

The dry leaf is similar to the 2009 Fukamushi Supreme in aroma, showing a larger-than-life bouquet of ripe exotic fruits that on the whole is reminiscent of a New Zealand Sauvignon Blanc; compared to the Fukamushi Supreme, it is less tangy, sweeter, fruitier (melon, papaya, some kiwi), and really tremendously enjoyable.

This aromatic register is reflected in the teacup. The scents are elegant and subtle: melon, pomelo, with an underlying vegetality. The combination of sweetness and vegetality (becoming a chewy bitterish seaweedy character when overbrewed) is also to be found in the flavour. There is nearly no astringency but quite a bit of thickness. And interestingly, the second infusion is best in nearly all my trials; while I usually rate my first infusions of Japanese greens highest, this tea is an exception. Somehow, it’s only in the second brewing that flavours seem to come together.

This tea is true to its name: miyabi, ‘elegance’. Despite its obvious thickness and a certain power it focuses around clean, elegant fruit flavours. To get the best of this character, I recommend dosing sparingly: in a comparative tasting with 2, 3 and 4 grams of leaf, the former version was the best.

Is this 2008 showing its age? Honestly, not much. It’s a clean, well-defined, reasonably complex tea of real personality, and it’s perhaps my favourite from the three sencha teas from O-Cha I’ve tried this year. But it’s even more ephemeral than the 2009 offerings from O-Cha, and its plateau of highest quality lasts only a few days from opening the pack; later, there’s a slightly drying seaweedy impression on the palate that’s a telltale sign of a Japanese green going stale. The 2009 is now available and I’m sure it won’t disappoint.

(3) 2009 Fukamushi Supreme Shincha

Let’s have a look at the 2009 Shincha Fukamushi Supreme. It’s another best-selling tea from O-Cha. Produced from the Yabukita varietal in the central region of Shizuoka. Priced at $23 / 100g.

Dry leaf: living up to its fukamushi [heavy- or long-steamed] name, this is very fragmented with few intact leaves. If you look at yesterday’s photo of the 2009 Yutakamidori, the difference is subtle but visible, as between chumushi [medium-steamed] and fukamushi. The most remarkable thing about this Fukamushi Supreme is the dry leaf aroma. It’s among the most intensely perfumed teas I’ve encountered. It’s a cornucopia of tangy exotic fruits, citrus, pomelo, melon, guyava, kumquat, you name it, with a subdued background grassiness and mild roast; a bouquet that positively reminds me of Marlborough Sauvignon Blanc wine from New Zealand. (The aroma also shows you how vital freshness is to this type of tea; four weeks after I opened the pack, it’s not quite the same thing, even stored in a double-lid tin).

Brewed as usually in the present series of reviews (2g / 120ml of water / 70C / 60 seconds), this tea pours a lighter colour than expected. While some chopped leaf residue makes it into the cup, the colour remains a pale green. It’s only with the second infusion (even if very short) that you get that legendary deep opaque emerald colour, like unfiltered olive oil from Central Italy:


Infusion no. 1 (60 seconds @ 70C) and 2 (25 seconds @ 80C).

The aroma is unfruity, fairly brothy, with a distinctive umami character. It’s also rather glutinous in texture from infusion #2 onwards. A dense, chewy tea with some dryness on the finish (as much a factor of astringency as texture). Interestingly, it isn’t exactly crisp, and technically has little acidity; the mouthfeel is similar to a light broth (if you cook it without lemon!) or miso soup. The melony fruit at core is soft and sweetish though, not citrusy, remaining the single fruit reference even in overinfusions at 95C. Second infusions at their densest move towards a more vegetal, chewy bean character (French beans).

Many Japanese tea drinkers have a preference for the full-on style of fukamushi teas, and I can see why this particular Fukamushi Supreme is so popular. Personally, I much like asamushi [short-steamed] Japanese greens, and so approached this tea with no positive bias. It is wholesome, of obviously good quality, and I’m perhaps doing it injustice expecting a bit more poise and zest.

As an aside, it’s one of the most short-lived teas I’ve come across, in the sense of an obvious drop in quality and complexity within a few weeks from opening the (nitrogen-filled as per O-Cha declaration) pack. While my inaugural sessions revealed some limey and grassy tang on the finish and were fairly vivid, four weeks later I am left with a simpler, flatter profile. This is understandable, fukamushi being one of the most fragmented leaf teas out there, and with the higher surface of exposure to air it just loses freshness so much more quickly than whole-leaf stuff.

In the second installment of my Japanese series I have a look at the 2009 Yutakamidori Shincha from reputed online merchant O-Cha. (As an aside, I want to praise their customer service: my original $100+ order went missing somewhere between Japan and Poland, and they’ve replaced it free of charge, even shipping by EMS. It’s the sort of attitude that guarantees a re-purchase there). At $25 / 100g it is priced at the upper middle end of the range for sencha (though objectively expensive).

Other than being a perennial favourite from O-Cha and one of the more consistently high-rating tea among writers and bloggers, the interest of this tea is that it is made with a single tea variety (‘cultivar’, ‘breed’, or ‘tea tree’): Yutakamidori. While Chinese tea is more often than not a single variety product, Japanese teas are frequently blended, and when they’re not, they are predominantly from the hardy Yabukita variety, which accounts for over 80% of plantings in Japan. Yutakamidori is one of the more popular cultivars, responsible for between 3 and 5% (according to various estimates) of tea plantations. It’s a variety typical of southern tea-growing regions: this example is from Kagoshima. Yutakamidori is often described as mild and sweet, yielding a brew that’s less grassy and pungent than Yabukita.

The loose leaf is far more fragmented than the Shigaraki Shincha I reviewed yesterday. While the latter was lightly steamed, leaving the leaf reasonably intact, this Yutakamidori saw a heavier steaming that resulted in more leaf breakage and a fair amount of fannings. O-Cha are classing this as heavy-steamed, but I think it’s more towards medium steaming [chumushi], or perhaps chumushi+ as there is still some intact leaf. The dry leaf smell is very intense and delightfully fruity; from the O-Cha sencha offerings I’ve ordered this year (reviews to follow in the next few days), this is the least tangy, and the fruitiest. There’s also a mild baked bread roast to be discerned when the leaves are warmed in the pot.

Look at the colour: a clear light green-yellow, becoming only partly cloudy in subsequent infusions. It’s another shincha that is, to evoke the descriptor generally used for this class of Japanese tea, not really ‘bold’. As Yutakamidori should be, it is mild, sweet, and fruity. There is never any citric or grassy tang that I associate with tea from other Japanese varieties. Instead, the fruit register centers around melon, papaya and lychee. Later on the palate there is a mealy, grainy, cerealy, perhaps ricey impression that has a bit of umami feel to it. Brewed conservatively at 70C with a minute or so of steeping, it doesn’t really develop much in terms of bitterness or kick. It is a clean, not to say pure, tea that in my experience requires a slightly higher dosage: 2.5 or even 2.8g per 100 ml of water.

It’s a very satisfying tea, a typical chumushi with good texture. But it’s not a monster of expression or intensity: the key characteristic is balance. The high quality is emphasised when you overbrew it: it becomes bitterish and strong, but maintains the same profile and isn’t really unpleasant. It’s the first time I’m tasting this renowned tea from O-Cha, and it’s living up to its fame.

This is chumushi.

Japanese fortnight (1): 2009 Shigaraki Shincha

Feeling like green tea?

Weeks are inexorably running since the spring tea harvest in Japan so it’s time to review this year’s releases (with a few 2008s thrown in) from O-Cha and Marukyu-Koyamaen. I hope my wine readers will enjoy this series as the next two weeks will be dedicated to Japanese tea reviews.
This 2009 Shigaraki Shincha is the second-cheapest from
Marukyu-Koyamaen (where I’ve received excellent service, and can heartily recommend this shop). At ¥900 / 90g can (and the cans are pretty nice: see photo), it is fairly inexpensive for a quality sencha. Shigaraki is a town historically renowned for its pottery; located next to Uji, I have no confirmation whether the leaves for this tea do indeed come from Shigaraki.

I have brewed this tea as all other Japanese greens in my reviews, alternating 150ml glass pot, 180ml Tokoname kyusu pot, and my favourite Korean clay pot (which you can see more extensively in this post), dosing at 2g / 100ml and with water at 70C, 75C, 80C (I find myself stopping by the third brew almost universally with Japanese teas; the first one is almost always the most enjoyable and revealing). Where there is a deviation from this regime I will indicate this.

As you can see from the picture, the dry leaf is of high quality: consistent, well-processed, good-looking asamushi [light-steamed] that fills the drinker with high expectations. The leaf has little distinctive aroma to speak of, lightly vegetal with little intensity; there’s no perceptible roast.

Brewing no. 1 (90 seconds at 70C).

In essence, this is a fairly light tea. It brews a light, transparent yellow-green colour, and is noticeably low in aroma. The flavour, however, is satisfying. No great intensity but a clean character, quite mild and unaggressive with no astringency whatsoever if brewed conservatively. It’s vegetal, leafy (but not grassy), less tangy than most sencha, with decent length. It’s not really thick but has a vaguely milky mildness to the texture, true to its asamushi peerage. Definitely uncomplex but I like it for its clean and classic profile. It’s also fairly forgiving: you really have to beat it hard on the head (i.e., going above 80C and dosing >3g) to develop any bitterness, and even then it’s of the clean invigorating kind.
Shincha [first spring harvest of sencha] is often defined as bold and powerful, and tea vendors routinely warn you against overbrewing it. As with sencha, there’s a wide variety of styles and it all really depends on the region, tea cultivar, grade, processing technique etc. This tea is everything but ‘bold’, which is fine with me. For the price, it’s utterly good, and I highly recommend it.

2008 Harayama Shincha

Kissing 2008 goodbye

My green teas from 2008 have to move out quickly to make room for 2009s. Longjing, Biluochun, Sencha are all being harvested at the moment, and some are ready for immediate EMS shipment.

But drinking tea up is no easy task. Any tea lover will know the embarras de richesse of a drawer full of samples. With 70 at this moment, I think I am among the least overstocked. Some teas can age, of course, and these will be happy with a few months’ oblivion as I delve into newly delivered 2009s. But fragile green teas – especially those from Japan, in my experience – should ideally be consumed within the year of harvest.

Today’s is definitely a belated note, then. The 2008 Harayama Shincha was made with the first spring harvest of last year. Shincha – ‘new tea’ – is often nicknamed the Beaujolais Nouveau of the tea world. It is equivalent to what the Chinese classify as pre-Qing Ming (or ming qian): the first spring buds plucked before this major Chinese festival that usually falls at the beginning of April. So in essence, this Harayama (a prestigious origin in the prestigious region of Uji) is an early harvest sencha Japanese green tea.

Merchant: Eastteas
Price: £16 / 100g
Brewed in: Korean clay cup (see photos)
Dosage: 4g / 120ml

Leaf: Immaculate elongated pressed leaves boast an impressively consistent dark green. This clearly belongs to the light-steamed family of Japanese tea (a.k.a. asamushi). I somehow found these wonderful leaves representative of the perfectionist Japanese aesthetics. Dry leaf smell is a concentrate of vegetality, with notes of asparagus, artichoke, and especially extra virgin olive oil.

Tasting notes:
1m @ 70C: A typical pale golden / celadon colour. The nose is quite aromatic with a top note I identified as nutmeg. Body is round and flavourful, allying sweetness with vegetal freshness, losing its bite gradually as there is very little overt grassiness: this is true to the shincha sort in being airy, light, without the tang of full-season sencha.
30s @ 70C: Good character, if a little less intensity than the first brewing. With fruity notes a bit lower, the full glutamic scharge is arriving with more power. This tea is easy to overbrew (in fact brewing at 85C results in too much astringency) but if you find the right balance it is really delightful.
80s @ 80C: Now slowly eclipsing into a vague greenish soup. Still pleasant but with limited interest.

Overall this tea has held reasonably well (my notes from November 2008 and this morning are consistent), and although hardly complex, it really delivers very good intensity of spring leaf flavour. Just what shincha should be. I can’t wait to receive my 2009s!

I also draw your attention to the lovely tea items on the photos (also purchased from Eastteas). The handy crackled celadon clay pot and accompanying cup are by Korean potter Mr. Bo Hyun, and have an effortless elegance while being very practical for brewing a single cup of green tea (especially fragmented-leaf, as in this case). The carved wooden tray is my Mr. Kang. It is perfect as a small tea table for one, or for serving three or four guest cups on.

Gyokuro Dejima-san

Shaking hands with umami

Japanese tea is not my cup of tea. As many (I think) tea drinkers, I have been put off by the overly grassy and fishy flavour these green teas can develop if brewed improperly. Not that the brewing window is narrower in this case than continental Chinese greens, but perhaps the failures are more unpleasant.

I have made a resolution to explore these teas in the coming season, so stay tuned for tasting notes appearing on this blog. Today I am starting at the very top – by a Gyokuro sourced from Eastteas. Any tea drinker will know that Gyokuro (tea made from shaded trees; when powdered it makes Matcha) is very particular in requiring a high dosage (which Japanese teas usually don’t) and surprisingly low brewing temperatures. Now, reaching those prescribed 45C is no easy task! From boiling water, it really takes long minutes of cooling the water (unless you want to mess up with several water coolers). For your effort, you get a very concentrated essence of vegetality, including a distinctive salty-savoury edge that embodies umami, the notorious ‘fifth taste’. (In this tea, it can be detected as tiny crystals of natural glutamate).

A water thermometer will be necessary
to reach the standard 40C brewing temperature of Gyokuro.
Gyokuro Dejima-san
Price: £48 / 100g
Brewed in: glass pot
Dosage: 4g/120ml
Leaf: Tiny, reasonably unmessy by Japanese standards (is asamushi a valid term for Gyokuro?), predominantly light green with some brighter tones; minor umami crystals here and there. Wet leaf is pleasant to look at, with no fannings and a consistent green colour. This shows the high quality of tea.

Tasting notes:
1m @ 40C: Colour is pale and aroma somewhat reticent but palate is indeed an explosion of umami taste: savoury, brothy (not salty!), glutamic, reminiscent of miso paste perhaps, with auxiliary notes of green peas and none of the grassiness of sencha. Good length, good intensity, good precision. Could actually have been brewed longer. (I started on the cautious side).
40s @ 50C: Less exciting than brewing #1, less intense though profile is consistent. No aggressivity or astringency whatsoever, this enters the mouth broad and flavourful with no hard edges. As often with second brewings of Japanese fragmented-leaf teas, this is a little murky in appearance and flavour now.
Further brewings are still pleasurable but you have to rise to 70C to obtain any intensity.
This is expensive tea, but the experience is interesting. Is it a top Gyokuro? I cannot by any stretch of the imagination be considered an expert in the subject but I would expect a bit more intensity and ‘bite’. But having been a little conservative with my dosage and brewing times, I guess this tea deserves the benefit of a doubt.
