Kukicha is a Japanese green tea made from the stems, stalks, and twigs of the tea plant, Camellia sinensis, rather than the leaves. It's a byproduct of making sencha, gyokuro, and matcha, gathered up and brewed on its own. The result is a light, naturally sweet cup with low bitterness and less caffeine than leaf tea. Tea lovers know it as twig tea, and it's one of the gentlest ways into Japanese green tea. This guide is part of our guide to Japanese green tea.

Key Takeaways

  • Kukicha (twig tea) is brewed from the stems and twigs of the tea plant, not the leaves.
  • It's naturally low in caffeine. One analysis measured a cup at about 25 mg, well under most leaf teas (Friedman et al., Journal of Food Science, 2005).
  • Kukicha is defined by the plant part it uses. Hojicha is defined by roasting, so the two overlap but aren't the same.
  • Its sweetness comes from L-theanine, the amino acid that travels up the stems from the roots.

Caffeine at a glance: Kukicha carries about 5 to 15 mg per 8-oz cup, low, because it is made from stems and twigs rather than leaf. See how it compares with every Japanese green tea in our caffeine-by-tea-type comparison.

What is kukicha?

Kukicha is a Japanese tea made from the stems, stalks, and twigs separated out during the production of leaf teas like sencha, gyokuro, and matcha. When farmers sort the harvest, the woody bits get set aside. Instead of discarding them, Japanese tea makers brew them into their own light, sweet tea. Nothing about it is second-rate. It's a distinct experience with its own character.

That thrift is part of why kukicha green tea has stayed popular for generations. It turns the whole plant into something worth drinking, which fits how tea has always been treated in Japan: with attention, and without waste. Drinking kukicha is a quiet reminder that the parts we overlook often carry their own gift.

Twigs and stems, not leaves

The defining feature of kukicha is simple. It's the twig, not the leaf. Regular kukicha comes from the stems left over from sencha or matcha. Higher grades come from more prized harvests, and they earn their own names. Kukicha made from the stems of gyokuro or top-grade sencha is called karigane, which means wild goose, and in some regions it's known as shiraore or bocha.

Because stems and twigs are structurally different from leaves, they brew differently. They're lower in the compounds that make tea bitter and astringent, and they hold more of what makes tea taste sweet. That single choice of material, twig over leaf, shapes everything about the cup: the color, the softness, the low caffeine, the gentle finish.

Kukicha vs hojicha: what's the difference?

Kukicha and hojicha get confused often, but they're sorted by two different rules. Kukicha is defined by the plant part, the stems and twigs. Hojicha is defined by the process, roasting, usually of leaves and stems (see our full guide to what hojicha is). One is about what the tea is made of. The other is about how it's treated.

Here's where it gets interesting. You can roast kukicha, and when you do, you get a roasted twig tea sometimes called kuki-hojicha. So the two categories overlap at the edges. Green kukicha is steamed and stays fresh and pale. Roasted kukicha crosses into hojicha territory, turning nutty and amber. Tea leaves are roasted at around 150 degrees Celsius (302 degrees Fahrenheit) to make hojicha (Wikipedia, Hōjicha). The plant part tells you it's kukicha. The roasting tells you it's also hojicha.

  Kukicha Hojicha
Defined by Plant part (stems and twigs) Process (roasting)
Typical color Pale green Amber to reddish brown
Flavor Light, sweet, gently nutty Toasty and roasted, low bitterness
Caffeine Low Low, roasting lowers it further
Where they meet Roasted kukicha, called kuki-hojicha, is both at once

How much caffeine is in kukicha?

Kukicha is naturally low in caffeine, though it isn't caffeine free. In a 2005 analysis published in the Journal of Food Science, a cup of kukicha, two grams steeped in eight ounces of hot water, measured about 25 mg of caffeine (Friedman et al., 2005). That's well under a typical cup of sencha and a fraction of a cup of coffee.

The reason is the material. Caffeine concentrates in the young leaves and buds of the tea plant, not the stems. Since kukicha is mostly stem and twig, it carries less of it. That makes twig tea a natural fit for the afternoon or evening, and it sits comfortably among the low-caffeine Japanese teas alongside hojicha and genmaicha. If you're building a rotation that lets you keep sipping past noon, our low-caffeine collection is a good place to start.

Where kukicha sits among the low-caffeine Japanese teas

Kukicha keeps good company. It belongs to a small family of gentle, low-caffeine Japanese teas that suit the later hours, sharing the shelf with hojicha and genmaicha. Each one earns its softness a different way. Kukicha leans on the stems and twigs it is made from. Hojicha leans on the roast. Genmaicha, green tea blended with roasted brown rice, borrows warmth and body from the grain. Reach for any of them when you want the ritual of tea without much caffeine.

Three gentle Japanese teas, sorted by what makes each one soft.
Tea Made from Flavor Caffeine
Kukicha Stems and twigs Light, sweet, gently nutty Low
Hojicha Roasted leaves and stems Toasty and warm, low bitterness Low
Genmaicha Green tea with roasted brown rice Savory, popcorn-like, comforting Low

What are the benefits of kukicha?

Kukicha's appeal comes down to its makeup: high in the sweet, savory amino acid L-theanine and low in bitterness and caffeine. L-theanine forms in the roots of the tea plant and travels up through the stems on its way to the leaves, so the twigs and stalks kukicha is made from retain a real share of it. Research associates L-theanine with a calm, focused feeling, though we'd frame that as an area of ongoing study, not a promise.

In the cup, that chemistry reads as a mellow, slightly nutty sweetness with almost no edge. Because it's gentle on caffeine, many people reach for kukicha benefits like an easy, low-astringency tea they can drink all day without the jitters. Like all green tea, it also contains catechins, the plant compounds studied for their antioxidant activity. We keep the language honest here: kukicha is a lovely, mild tea, and we won't pretend it's medicine.

How do you brew kukicha?

Brewing kukicha is forgiving, which is part of its charm. Green kukicha likes cooler water and a short steep. Roasted kukicha can take hotter water. Here's the simple version.

  1. Warm your teapot, then add about one tablespoon of kukicha, roughly four to five grams, per cup.
  2. Heat your water to 70 to 80 degrees Celsius, that's 158 to 176 degrees Fahrenheit, for green kukicha. For roasted kukicha, use hotter, near-boiling water.
  3. Pour the water over the twigs and let them unfurl.
  4. Steep green kukicha for 30 to 60 seconds. A minute gives you a fuller cup (Wikipedia, Kukicha).
  5. Pour off completely, down to the last drop, so the next steep stays bright. Good kukicha gives you two or three infusions.

Water temperature 70 to 80°C (158 to 176°F)
Steep time 30 to 60 seconds
Infusions 2 to 3
Best time of day Afternoon or evening
Roasted kukicha Same tea, but use hotter, near-boiling water
A quick reference for brewing kukicha. Roasted kukicha takes hotter water than green.

Slow down for it. Watch the twigs open, notice the pale color, breathe in before the first sip. Kukicha rewards presence more than precision.

Frequently asked questions

Is kukicha caffeine free?

No, kukicha is low in caffeine but not caffeine free. One analysis measured a cup at about 25 mg (Friedman et al., 2005), well below most leaf teas because caffeine concentrates in leaves, not the stems and twigs kukicha is made from. It's a common choice for the afternoon and evening.

What does kukicha taste like?

Kukicha is light, smooth, and naturally sweet with very little bitterness, thanks to its high L-theanine and low caffeine. Green kukicha tastes fresh and grassy with a soft, nutty edge. Roasted kukicha turns warmer and toastier, closer to hojicha in character.

Is kukicha the same as hojicha?

Not quite. Kukicha is defined by the plant part it uses, the stems and twigs. Hojicha is defined by roasting. The two overlap because you can roast kukicha, producing a tea sometimes called kuki-hojicha, but plain kukicha is a green, unroasted twig tea.

What is karigane?

Karigane is a higher grade of kukicha made from the stems of gyokuro or top-grade sencha rather than everyday sencha. It's prized for extra sweetness and depth. In some regions the same tea is called shiraore or bocha. All of them are twig teas at heart.

Can you drink kukicha at night?

Many people do, because kukicha's low caffeine, roughly 25 mg per cup in one measurement, makes it a gentle evening tea. Sensitivity varies from person to person, so trust your own body. If caffeine keeps you up, keep the steep short and the cup earlier.
