Sencha (煎茶) is where Japanese green tea really lives. Matcha gets the attention, but sencha is the tea most people in Japan actually drink every day — at the desk, after a meal, poured cold in summer. This guide explains what sencha is, how it differs from matcha and from Chinese green tea, how much caffeine it has, what the research says about its benefits, and — the part most people get wrong — how to brew it so it stays sweet and green rather than bitter.
What sencha actually is
Sencha is made from the same plant as every other true tea — green, oolong, black and white all come from Camellia sinensis. What makes a tea "green" is that it isn't allowed to oxidise, and what makes it sencha specifically is how that's done: the fresh leaves are steamed within hours of picking.
That single step is the whole story. Steaming halts the enzymes that would otherwise brown the leaf, so sencha keeps the character of the living leaf — the grassiness, the fresh green colour, and the amino acids (especially L-theanine) that give good Japanese green tea its savoury, almost brothy depth. The steamed leaf is then rolled into fine needle shapes and dried. Brew it, and you get that unmistakable bright, vegetal, faintly oceanic cup.
Sencha vs matcha vs Chinese green tea
These three get confused constantly. They're all green tea; they're made very differently, and they taste it.
| Sencha | Matcha | Chinese green (e.g. dragonwell) | |
|---|---|---|---|
| How it's made | Steamed, rolled, dried — brewed as loose leaf | Shade-grown, steamed, stone-ground to powder — whisked, whole leaf consumed | Usually pan-fired, then rolled and dried |
| Flavour | Grassy, fresh, faintly marine, clean | Intense, creamy, savoury, vegetal | Nutty, toasty, mellow, chestnut-like |
| Colour | Vivid green | Bright jade | Pale gold-green |
| Caffeine (per cup) | ~25–45 mg | ~60–70 mg (whole leaf) | ~25–40 mg |
| Best for | Everyday drinking, hot or iced | Lattes, baking, a strong lift | Gentle, all-day sipping |
The short version: sencha is steamed and Chinese green is pan-fired — that's why sencha tastes fresh and grassy while a Chinese green tastes nuttier and mellower. And matcha is the whole leaf ground to powder, so it's more concentrated and higher in caffeine than steeped sencha. If you like matcha's savoury depth but want something lighter and easier to drink all day, sencha is the natural everyday choice.
How much caffeine is in sencha?
A cup of sencha typically carries about 25–45 mg of caffeine — roughly a third to a half of a standard coffee (~95 mg). The exact amount depends on how much leaf you use, the water temperature and the steep time: hotter water and longer steeping pull more caffeine (and more bitterness) into the cup.
Sencha also contains L-theanine, an amino acid that promotes a calm, focused alertness. The combination of caffeine and L-theanine is why many people find green tea gives a steadier, less jittery lift than coffee — a gentle wakefulness rather than a spike.
Is sencha good for you? What the research says
Sencha is one of the more studied green teas because it's so widely consumed in Japan. Like other green teas, it's a source of catechins (notably EGCG) and other antioxidant polyphenols. Research on green tea generally associates regular, moderate consumption with antioxidant activity and supportive roles in everyday wellbeing; it is a healthy, low-kilojoule drink when taken without sugar.
A sensible way to think about it: sencha is a genuinely good everyday drink, not a medicine. Enjoy it as part of a balanced diet rather than as a treatment, and if you're pregnant, sensitive to caffeine or managing a health condition, factor in its caffeine and check with your GP.
How to brew sencha (the one thing to get right)
Most people brew sencha like black tea — boiling water, a long steep — and then wonder why it's bitter and dull. Sencha wants a gentler hand:
- Water temperature: 70–80 °C, not boiling. Boil the kettle, then let it sit 2–3 minutes, or add a splash of cool water.
- Leaf: about one teaspoon (2–3 g) per cup (roughly 200–250 ml).
- Steep time: 60–90 seconds for the first infusion. No longer.
- Re-steep: good sencha gives 2–3 infusions — add 10–20 seconds each time.
- Iced sencha: brew double-strength and pour straight over ice, or cold-brew in the fridge for 3–4 hours for the sweetest, least bitter cup. Ideal for an Australian summer.
Why the cooler water? Heat pulls out catechins (bitterness) fast, while the sweeter amino acids release at lower temperatures. Cooler water for a shorter time gives you sencha's sweetness and umami; boiling water gives you its bitterness. That's the whole trick.
Why sencha can taste bitter — and how blends soften it
A little grassy bitterness is part of sencha's character, and in a good cup it resolves into huígān — a returning sweetness that arrives after the initial edge. But harsh, flat bitterness usually means the water was too hot or the steep too long (see above).
Some modern blends also soften sencha deliberately by pairing it with fruit or floral notes, so the fresh green base stays but the finish is rounder and sweeter. Our own Tropical Ripple pineapple sencha is built exactly this way — Japanese sencha and matcha powder under candied pineapple, so a bright tropical sweetness ripples across the grassy green and settles back into a gentle, sweet finish. It keeps a touch of the bitterness on purpose, because that's where the Japanese-green character lives.

How to choose a good sencha
- Colour: look for vivid, fresh green leaf, not dull olive or brown.
- Aroma: it should smell grassy and fresh, like cut greens or seaweed — a stale or hay-like smell means old tea.
- Origin: genuine Japanese sencha is steamed; a tea simply labelled "green tea" may be pan-fired and taste quite different.
- Freshness: green tea fades. Buy in sensible quantities, keep it airtight and away from light, and drink it within a few months of opening.

Frequently asked questions
What is sencha?
Sencha is Japan's most popular green tea — a whole-leaf tea from Camellia sinensis that is steamed soon after picking, then rolled and dried. Steaming gives it a fresh, grassy, faintly marine flavour and a vivid green colour.
What is the difference between sencha and matcha?
Both are steamed Japanese green teas, but matcha is shade-grown and stone-ground into a fine powder that you whisk and drink whole, so it's more concentrated and higher in caffeine. Sencha is loose leaf that you steep and strain — lighter, grassier and better for everyday drinking.
How much caffeine does sencha have?
About 25–45 mg per cup, roughly a third to a half of a coffee. Hotter water and longer steeping increase the caffeine (and the bitterness).
Is sencha good for you?
Sencha is a source of antioxidant catechins and L-theanine and, taken without sugar, is a healthy low-kilojoule everyday drink. It's a good habit, not a medicine — enjoy it as part of a balanced diet.
Why is my sencha bitter?
Almost always because the water was too hot or the tea steeped too long. Use water at 70–80 °C for 60–90 seconds. A faint bitterness that turns sweet (huígān) is normal and desirable; harsh flat bitterness is a brewing fault.
Can you drink sencha iced?
Yes — it's excellent iced. Brew double-strength and pour over ice, or cold-brew in the fridge for 3–4 hours for the sweetest, smoothest result.
