How to Brew Sencha at Home

Matcha is the tea Japan performs. Sencha is the tea Japan drinks — poured after lunch, refilled at a desk, handed to a guest before anyone has decided why they came. It makes up a little over half of the country’s tea production, and almost none of that is ceremony.

It is also the tea most easily ruined. Sencha asks for three numbers — how much leaf, how hot the water, how long you wait — and gets two of them wrong in most Western kitchens. Here is how to get all three right, and what to do with the second steeping, which is where sencha actually shows its hand.

The short answer

Leaf: about 2–3 g per person — noticeably more than you’d get from a teabag.
Water: 70–80°C, never boiling. For premium leaf, go lower: 60–70°C.
Time: 60–90 seconds for the first steeping — up to two minutes for a premium leaf brewed cool. Then 20–30 seconds for the second.
The pour: empty the pot completely, down to the last drop, every time.

What you need

You need less than the shelf of a tea shop suggests.

A kyusu (急須) — the side-handled Japanese teapot, ideally 200–300 ml with a fine built-in strainer. Sencha is a fine, needle-shaped leaf with a lot of small particles, and a pot that can’t filter them sends sediment into the cup. If you’re choosing one, we go through handles, clay, and mesh in Choosing a Kyusu.
Small cups (yunomi) — 60–100 ml. Japanese green tea is served in small amounts, hot, and drunk before it cools.
A yuzamashi (湯冷まし) — optional. A wide, open cooling vessel; you pour boiling water into it and let the extra heat go. Nice to have, not required.

That’s the whole kit. No scale, no thermometer, no timer — though a thermometer for the first week is the fastest way to learn what 75°C looks like coming off your kettle.

The three numbers

Tea	Leaf	Water	Temperature	First steeping
Everyday sencha	2–3 g per person	60–90 ml per person	70–80°C	60–90 s
Premium sencha / kabusecha	5 g	80 ml	60–70°C	60–90 s
Gyokuro	10 g	100 ml	50–60°C	~2½ min
Bancha, hōjicha, genmaicha	5 g	180 ml	90–100°C	20–30 s

Two things stand out in that table. The first is how little water goes with the leaf — sencha is brewed strong and short, in cups you finish quickly, not in mugs you nurse. The second is that the better the leaf, the cooler the water. That inversion is the whole trick.

Why the water can’t be boiling

The usual explanation runs like this: the compounds that make green tea sweet and savoury — the amino acids, theanine among them — come out of the leaf readily at lower temperatures. The compounds that make it bitter and astringent — the catechins — need more heat and more time. Pour boiling water on sencha and you extract everything at once, and the bitterness drowns the rest.

So the temperature isn’t a fussy detail. It’s the dial you turn to choose which tea you get out of the same leaf.

If you don’t own a thermometer, the low-tech method works fine. As a rough rule of thumb, hot water poured into a room-temperature vessel loses somewhere around 10°C with each transfer. Kettle → yuzamashi → kyusu brings boiling water down towards 80°C. Kettle → cup → yuzamashi → kyusu takes it lower still, which is how gyokuro is traditionally cooled — passed from vessel to vessel until it’s calm enough for the leaf. The exact drop depends on your room, your vessels, and how long the water sits, so treat it as a starting point and taste your way from there.

The method

Warm the cups. Pour hot water into each cup, about a third full. This both preheats them and — usefully — cools the water on its way to the pot.
Leaf into the kyusu. 2–3 g per person, straight in. No infuser basket; the leaf needs the whole pot to open.
Pour the cooled water from the cups onto the leaf. Roughly 60–90 ml per person.
Wait 60–90 seconds. Don’t stir, don’t swirl, don’t lift the lid to look. A premium leaf brewed cooler wants closer to two minutes — Kyoto’s tea research institute times it by eye, waiting until the leaves have opened about 70–80%.
Pour in rounds — a little into cup one, two, three, then back again in reverse, and again (mawashi-tsugi, 回し注ぎ). The tea in the pot is weak at the start of the pour and concentrated at the end, so filling one cup at a time hands the first person weak tea and the last person strong tea. Going back and forth gives everyone the same cup.
Empty the pot completely. Tip it until the last drop falls — the final, most concentrated drops are worth sharing out rather than leaving behind. This matters more than it sounds.

The second cup

Step 6 is the one people skip, and it’s the one that decides the second steeping.

Water left standing in the pot keeps extracting — hot, unattended, for however long you leave it — and by the time you come back the leaf has given up its bitterness into a puddle. Pour that away and pour fresh water on, and you’re brewing over a ruined base. Kyoto Prefecture’s tea research institute gives the instruction as part of the pour itself: squeeze the pot out to the last drop, every time.

Drain it fully and the second steeping is easy, and often the best of the session:

Second: slightly hotter water, 20–30 seconds. Barely a wait — the leaf is already open.
Third: hotter again, 30–45 seconds. Lighter, rounder, and worth having.

Good sencha gives three infusions. Each one is a different tea, and part of the pleasure is noticing which of the three you like most — many people find it’s the second.

Choosing the leaf

Once the method is steady, the leaf is the only variable left.

Asamushi (浅蒸し) — lightly steamed, roughly 20–40 seconds in processing. Clear, pale-gold liquor; crisp, bright, a clean edge of astringency. Steep it a touch longer, 60–90 seconds.
Fukamushi (深蒸し) — deep-steamed, roughly 60–120 seconds. The extra steaming breaks the leaf down further, so the cup is cloudy deep green, fuller-bodied and sweeter, with less astringency. Steep it shorter — 45–60 seconds — and use a fine mesh, because the leaf is powdery.
Shincha (新茶) — the first harvest of the year, sold in late spring. Fresh, grassy, and best drunk soon rather than saved.
Kabusecha (かぶせ茶) — sencha shaded for about a week to ten days before picking. Sits between sencha and gyokuro: sencha’s freshness with some of gyokuro’s sweetness. Brew it like premium sencha, cooler.

Sencha is usually grown unshaded, in full sun — shaded versions like kabusecha are the exception rather than the rule. Gyokuro is shaded for around twenty days or more, which is why it wants 50–60°C water and a slower, completely different rhythm.

Where to start: an everyday fukamushi sencha is the most forgiving leaf to learn on, and widely drunk in Japanese homes. Pair it with a kyusu that has a fine ceramic or stainless mesh — browse hand-picked, Japan-shipped tea ware on The Table.

Cold brew, for summer

Sencha cold-brews beautifully, and it’s hard to get wrong: cold water draws out far less of the bitter, astringent side of the leaf, so the result comes out sweet and soft almost by default.

10 g of leaf to 1 litre of water at 5–15°C, in the fridge for 1–2 hours. Strain and drink within a day. High-grade sencha rewards this method more than any other. A quicker version: put leaf in a glass, pile ice on top, and let it melt.

Five ways sencha goes wrong

Boiling water. The single most common mistake, and the one that makes people think they dislike green tea.
Too little leaf. Teabag habits don’t transfer. Sencha is brewed strong and short.
Hot water and a long steep together. Either alone is survivable; combined, astringency takes over. If you’re brewing near 80°C, keep the first infusion short — the long, patient steeps belong to cooler water and better leaf.
Leaving water in the pot. Ruins the second cup before it starts.
Old leaf. Sencha fades. Keep it sealed, cool, dark, and away from anything with a smell — tea takes on odours readily — and drink it within weeks of opening, not months.

Where sencha came from

It’s worth knowing that the tea in your pot is a specific invention with a date on it. In 1738, Nagatani Sōen of Ujitawara, south of Kyoto, developed the aosei sencha method: instead of pan-roasting the leaves in the Chinese manner, he steamed the fresh shoots to halt oxidation, then rolled and dried them by hand on a hoiro, a heated rolling table. The result held its green colour, aroma and sweetness far better than the old method. It sold well in Edo, spread through the tea regions, and became the foundation of how sencha — and gyokuro, which is processed the same way from shaded leaf — is made today.

Not every Japanese green tea followed him. Tencha, the leaf that gets stone-ground into matcha, is steamed but deliberately never rolled; it’s dried flat, then stripped of stem and vein. Rolling is what gives sencha its needle shape, and what breaks the leaf’s cells open so it releases flavour quickly in the pot — which is precisely why sencha is brewed in seconds and matcha isn’t brewed at all.

Steaming rather than pan-roasting is commonly credited with the vegetal, almost marine character that distinguishes Japanese green tea from the nuttier, toastier Chinese style. One decision, in one village, in 1738.

What to reach for

If you…	Start with
are buying your first setup	kyusu 200–300 ml + fukamushi sencha, nothing else
already own a Western teapot	it works — just use cooler water and less of it
find green tea bitter	drop to 70°C and 45 seconds, then adjust up
want the umami version	premium sencha or kabusecha at 60°C, 5 g to 80 ml
are brewing for summer	cold brew, 10 g per litre, overnight

The rule underneath all of it: sencha is a short brew, drunk hot, in small cups, three times over. Get the water off the boil and the pot fully emptied, and everything else is preference.
