How to Brew Sencha Like a Japanese Grandmother

By Sen, from a kitchen in Tokyo · Updated July 30, 2026

My grandparents’ house had a specific smell in the afternoon: steamed rice, tatami, and sencha brewed in a small ceramic teapot called a kyusu. The tea that came out of that unremarkable pot tasted alive — sweet, deep, almost savory — in a way that took me years to understand, because the same leaves at home, brewed carelessly, tasted like lawn clippings.

The difference was never the leaves. It was three variables my grandmother controlled without ever thinking about them, the way you flip a pancake without a timer.

The short answer: 4 grams of leaves, 200 ml of water cooled to about 70°C, steeped 60 seconds in a pot that lets the leaves open flat. Pour to the last drop. That’s the entire family secret, and it’s yours now.

Variable 1: water temperature (the big one)

Sencha is even more temperature-sensitive than matcha. At boiling, you extract bitterness almost instantly. At around 70°C / 158°F, the sweetness and umami — the amino acid theanine that good sencha is prized for — come forward while the harsh notes stay in the leaf.

The traditional method needs no thermometer: pour boiling water into the empty cups first. This warms the cups, cools the water about 10°C, and measures your exact volume in one move. Wait a minute, pour that water into the pot. Two transfers gets you near 70°C. It’s the kind of efficiency that looks like ritual but is really just physics learned by generations of thumbs.

Variable 2: the pot (why the kyusu matters)

A kyusu is a small side-handled teapot, and its important feature isn’t the handle — it’s the size. At 200–300 ml, leaves have room to unfurl completely while staying concentrated. A big Western teapot dilutes sencha into vagueness; a mug with a deep infuser basket crushes the leaves into a column.

Do you need one? An honest answer: any small pot with a built-in strainer gets you 90% of the way. But a proper kyusu [AFFILIATE-LINK: kyusu teapot] costs about the same as two bags of good tea, lasts decades, and — speaking as someone whose strongest tea memories all involve one — the object itself is part of why the habit sticks.

Variable 3: pour to the last drop

Watch anyone’s Japanese grandmother pour tea and you’ll see the pot shaken gently over the final cup until it stops dripping. This isn’t frugality. The last drops are the most concentrated — in Japan they’re called the “golden drop” — and leaving them in the pot does two bad things: it wastes the best part, and it lets the remaining leaves keep stewing, ruining the second steep.

Second steep, by the way: same leaves, slightly hotter water, 20 seconds. Many people in Japan think it’s the better cup.

The full method, start to finish

1. Boiling water into the empty cups (warms cups, measures volume, drops temperature)
2. 4 g of sencha (two teaspoons) into the pot
3. Water from cups into pot — now around 70°C
4. 60 seconds. No swirling, no stirring. Patience
5. Pour in rounds across cups (a little in each, back and forth) so every cup is even strength
6. Shake out the last drops. Always

Buying sencha worth brewing well

The label rules from our matcha guide apply here too: named region (Shizuoka, Uji, Yame, Kagoshima), first-harvest (shincha in spring is the festival version), a packed-on date. One sencha-specific tip: fukamushi (deep-steamed) sencha is cloudier, richer, and more forgiving — a good first bag for someone coming from teabags. [AFFILIATE-LINK: recommended sencha]

And if your daily reality is cold-brew in the fridge — a pitcher, a handful of leaves, overnight — that’s not cheating. That’s how tea actually got consumed in my house growing up, and cold-brewed sencha is naturally sweet because the bitter compounds barely extract in cold water. The kyusu is for the afternoons that deserve it.

The unremarkable pot

Nobody in my family ever called sencha brewing a ceremony. It was just how tea got made — small pot, cooled water, last drop shaken out, second steep before the conversation ended. Ceremony is what it looks like from outside; from inside, it’s just care, repeated until it’s invisible.
