The Origin

From the gardens of Uji.

Kukicha is the Japanese tea you've never had right. Made from the stems, twigs, and stalks of the tea plant rather than the leaves, it is the quiet, low-caffeine, sweet-vegetal Japanese household tea. Where sencha gives bright vegetal grass and gyokuro gives concentrated umami, kukicha gives mild sweetness, hay, and a clean mineral body. The cup is pale gold, the register is gentle, and the caffeine is barely there.

We source Karigane — the technical name for stem tea from gyokuro and high-grade sencha processing, sometimes called the "wild goose" tea after the long stalks that resemble its neck. Karigane is the most refined kukicha grade: the stems carry residual sweetness from the shading process used to grow gyokuro, and that sweetness comes through clearly in the cup. Our source is a single Uji producer who treats karigane as a deliberate product, not a by-product.

The Process

Stems, twigs, and the cup that comes from the side.

Kukicha begins with the gyokuro or sencha harvest. After the leaf is graded and the highest-grade tea is reserved for export, what remains is the stem-and-twig material that carries the same plant's character in a different ratio. Stems hold more theanine and less caffeine than the leaves do. Twigs add a soft mineral note. The combination produces a cup that's lighter, sweeter, and dramatically lower in caffeine than the leaf tea it came from.

We work with a small Uji producer who treats karigane as a deliberate product rather than a by-product. The stems are hand-sorted, briefly steamed to halt oxidation, then gently dried and sealed. No roasting, no flavoring, no blending. The cup that arrives is exactly what stem tea from Uji tastes like in spring.

i
Source
Karigane material from Uji gyokuro and high-grade sencha processing. Hand-sorted to keep the stems and twigs and remove leaf fragments.
ii
Steam
Brief steaming, about 30 seconds, to halt oxidation. The same kill-green principle as sencha but adjusted lighter for the stem material.
iii
Dry
Gentle drying to roughly 5% moisture content. No roasting, no firing, no heat-treatment beyond the steam. The leaf stays green and the natural sweetness is preserved.
iv
Sachet
Hand-graded into pyramid sachets within weeks of the harvest. Gold-foil sealed at the moment of packing. Kukicha's aromatic compounds are delicate and fade quickly once exposed.
The Cup

Hay, light umami, sweet mineral. The quietest cup in the box.

The colour is a pale gold, almost translucent. The aroma is the unmistakable kukicha nose. Fresh hay, mild grass, a hint of milky umami, and the soft underlying sweetness that distinguishes karigane from leaf-only kukicha.

First — The Aroma
Fresh hay, mild grass, milky umami
The karigane nose. Soft, light, vegetal but not bright. Where sencha smells like a green field, karigane smells like the air over hay drying in the sun. Quiet, low, and considered.
Then — The Body
Sweet stems, light umami, clean mineral
The body is gentler than its colour suggests. There's a real sweetness in the cup that comes from the stems specifically. They carry more sugars than the leaf does. A whisper of umami, no astringency at all.
Last — The Echo
Long clean finish, returning sweetness, calm
The finish is the calmest of any tea in the box. Clean, faintly sweet, with a return note that arrives several seconds in. Many drinkers describe a settling effect — partly the very low caffeine, partly the calmness of the cup itself.

A tea for after dinner, for the conversation that has slowed down, or for the cup when nothing more demanding is wanted.

The Ritual

Cool water. Brief steep. The simplest tea in the box.

Kukicha asks for nothing complicated. Cool water (the stems are delicate; boiling water scalds them), 60 to 90 seconds, and the cup is ready. The least temperamental tea in the lineup, and the most welcoming.

i
1
Sachet
Drop the unopened pyramid into a 10oz cup or pot. The stems unfurl quickly in warm water; no advance preparation needed.
ii
160°F
Water
Roughly 70°C. Karigane is delicate. The stems give up their sweetness easily and don't need heat to extract them. Boiling water turns the cup bitter and dull.
iii
60-90 sec
Steep
One minute for the standard cup. Up to 90 seconds for a more pronounced register. Past two minutes, even kukicha can turn a touch bitter.
iv
2-3×
Pour
A second pour at one minute is welcome. The cup is rounder and slightly sweeter the second time. A third is light but still pleasant.
The Why

The Japanese tea you can drink at any hour.

Kukicha is the Japanese tea you can drink at any hour. The stem-and-twig composition gives it very low caffeine. Roughly 5 to 15mg per cup, less than a fifth of a black tea. Children drink it, the elderly drink it, and you can pour it after dinner without disturbing sleep. Japan calls it the household tea, and it earns the name.

Most kukicha sold in the West is leaf-only and machine-processed. The cup that arrives is thin, vegetal in an uninteresting way, and lacks the sweetness that defines the Uji register. We chose Karigane — the high-grade stem-and-twig material from Uji gyokuro and high-grade sencha processing — because it's the most refined expression of the category. Stems carry residual sweetness from the shading process used to grow gyokuro, and that sweetness comes through cleanly in the cup.

Saint Graal sources from a single Uji producer who hand-sorts the karigane material and packages it within weeks of harvest. Steamed, gently dried, never roasted. The cup that arrives is exactly what stem tea from Uji tastes like in spring. Light, sweet, mineral, and as quiet as tea gets.

Common Questions
What does kukicha taste like?
+
Light hay, mild grass, a soft umami in the back of the cup, and an underlying sweetness that distinguishes karigane (the high-grade stem tea from gyokuro and high-grade sencha processing) from leaf-only kukicha. The cup is pale gold, the body is gentle, and there is no astringency. If you find sencha too bright or gyokuro too concentrated, kukicha is the same plant family in a much quieter register.
What is Karigane kukicha specifically?
+
Karigane (literally "wild goose") is the Kyoto term for the stem-and-twig material left from gyokuro and high-grade sencha processing. Un-roasted, it is karigane kukicha — the soft, sweet, hay-noted cup. Roasted, the same material becomes karigane hojicha, a deeper toasted register. The stems carry residual sweetness from the shading process used to grow gyokuro, which is why karigane is considered the most refined kukicha grade. Ours is the un-roasted form.
How much caffeine does kukicha have?
+
Very low. Stems and twigs contain dramatically less caffeine than leaves. Roughly 5 to 15mg per cup, less than a fifth of a black tea, less than a third of a green tea. Kukicha is the traditional Japanese answer to "can I drink tea at night?" Yes you can. This one.
Can children and the elderly drink kukicha?
+
Yes, and that is a traditional feature of the category in Japan. The very low caffeine, the gentle profile, and the soft sweetness make kukicha the household tea served to all ages, often at meals. Japanese pediatricians and elder-care practitioners do not regard it as problematic the way they would a strong green tea or coffee.
When should I drink kukicha?
+
Any time of day. Traditionally it is a household tea in Japan served at meals and throughout the day. The very low caffeine makes it the only tea in the box that is truly evening-friendly. Pair with light food, soft cheese, citrus desserts, or nothing at all.
