What Is Sencha Tea? Benefits, Caffeine, Taste and How It Is Made
By Kiyomi Koike, Founder and ITMA Certified Tea Master · Updated October 2026
What is sencha? Sencha is Japan's everyday green tea: leaf grown in full sun, steamed within hours of picking to keep it green, rolled into fine needles and dried. More than half of all the tea made in Japan is sencha, and it is the cup most Japanese families drink from morning to night. It tastes bright, grassy and gently sweet, with a clean finish, carries less caffeine than matcha, and, because the leaf grows in sunlight, it is unusually rich in catechins, the antioxidants green tea is known for. Organic Sencha powder has been our signature tea since Yu Tea began in 2004, and we make it as a whole-leaf powder rather than a loose leaf to brew. On this page I explain where sencha comes from, how it is grown and made, how it compares with matcha and the other Japanese teas, what it tastes like, what is in it, how much caffeine it carries, and how to drink it.
| What it is | Sun-grown Japanese green tea, steamed and rolled; the most common tea in Japan |
| Taste | Bright and crisp: spring greens, a hint of wildflower honey, soft umami, a clean, slightly citrusy finish |
| Caffeine | A brewed cup of green tea, sencha included, 24–40 mg per 8 oz (industry range); our Sencha powder about 20 mg per 0.75 g serving, from our most recent batch testing; results vary by lot and by packaging |
| EGCG | 65 mg per 0.75 g serving of our powder in the latest batch, from the same testing |
| Serving and water | 0.75 g, one stick or a heaping ¼ teaspoon, in 6–12 oz of water at 165°F (74°C) or below; cold: the same in 8 oz, shaken |
| Formats | Whole-leaf powder, 30 single-serve sticks or a 100-serving pouch; a decaf version with about 4 mg of caffeine |
| Best for | All-day drinking, a lighter taste than matcha, cooking and iced tea; more EGCG per gram than matcha at about half the caffeine and a fraction of the price |
What sencha means, and where it comes from
The word is written 煎茶 in Japanese: sen, to infuse or simmer, and cha, tea. It was named for the way it is drunk, leaves steeped in hot water, which set it apart from matcha, the powdered tea that had been whisked in Japan for centuries before. The method behind it, steaming the fresh leaf and then rolling it while it dries, was developed in Uji in 1738 by a tea maker named Nagatani Soen, and it spread so quickly that it became the standard way to make green tea across the country. Today more than half of Japan's tea crop is made into sencha. Matcha belongs to the tea ceremony; sencha belongs to the kitchen table, the office and the thermos, and the two are not rivals so much as different occasions.
How sencha is grown and made
Everything that makes sencha taste the way it does happens in four steps, and the first one is the sun.
- Grown in full sun. Sencha bushes are never covered. In sunlight the plant converts much of its L-theanine, the amino acid behind matcha's umami, into catechins, the family of antioxidants that includes EGCG, which the leaf uses to protect itself from ultraviolet light. That single difference explains most of the contrast with shade-grown matcha: sencha is brighter and more astringent, a little less savory, and higher in catechins gram for gram.
- Picked in spring. The first harvest of the year, called ichibancha, gives the most tender leaf and the sweetest, most aromatic tea; later harvests are coarser and more astringent. Our sencha is first harvest.
- Steamed within hours. The picked leaf is steamed, for anywhere from about twenty seconds to a couple of minutes depending on the style, to stop the enzymes that would otherwise oxidize it into black tea. This is what makes Japanese green tea green, and it is the step that separates sencha from Chinese green teas, which are pan-fired instead. Longer steaming, fukamushi, gives a deeper, cloudier, softer cup; shorter steaming, asamushi, a clearer and more delicate one.
- Rolled and dried. The steamed leaf is kneaded and rolled while it dries, which breaks the cell walls so the leaf gives up its flavor in the cup, and shapes it into the thin green needles you see in a tin of loose sencha.
Most sencha stops there and is sold as loose leaf. Ours takes one more step: we grind the finished first-harvest leaf on the same kind of granite stone mill we use for matcha, into a powder you whisk into water and drink whole. The reason is simple. When you brew sencha and discard the leaf, a large share of its catechins stay behind in the pot; when you drink the powder, everything the leaf holds ends up in your cup. I say more about that choice below.
Sencha vs matcha, gyokuro, bancha, hojicha and genmaicha
"Green tea" in Japan means several different teas from the same plant, and sencha is the reference point for all of them.
| Sencha | Sun-grown, steamed, rolled; the everyday standard. Bright and grassy; moderate caffeine |
|---|---|
| Matcha | Shaded for at least 20 days, usually three to four weeks, before harvest; de-stemmed and stone-milled to a powder you whisk. Savory, creamy, more caffeine and more L-theanine |
| Gyokuro | Shaded like matcha but kept as loose leaf and brewed cool; the sweetest, most umami-rich leaf tea, and the most expensive |
| Kabusecha | Sencha shaded briefly, a week or two; halfway between sencha and gyokuro |
| Bancha | Sencha's later harvests and larger leaves; plainer, lighter in caffeine, the cheapest everyday tea |
| Hojicha and genmaicha | Roasted green tea, and green tea blended with toasted rice; both nutty and mellow, with modest caffeine |
The comparison people ask me about most is sencha against matcha, and I have given it its own page: sencha vs matcha on taste, caffeine, EGCG and price. The shade-grown side of the family is explained on our complete guide to matcha, and the toasty teas on our guide to hojicha and our guide to genmaicha. If you have only ever had green tea from a supermarket bag, which is usually a blend of lesser leaf, sencha is the tea it was trying to be.
What sencha tastes like
Sencha is bright and crisp where matcha is deep and creamy. The first impression is fresh greenness, like spring greens or cut grass, with a natural sweetness underneath that we describe on our product page as a hint of wildflower honey. There is a soft umami, less than matcha's because the leaf grew in sun, and a clean, slightly citrusy finish with a touch of astringency that makes the next sip welcome. Fresh sencha smells of cut grass and a little of the sea; stale sencha smells of hay. It is a tea you can drink cup after cup without tiring of it, which is exactly why Japan drinks it all day. If you prefer a savory, rich, slow cup, choose matcha; if you prefer light, refreshing and easy, you are a sencha drinker.
Sencha benefits: what is in the leaf
I sell tea, so read this section with that in mind, and I will stick to what we measure and what the research supports. Sencha's reputation rests on its catechins, led by EGCG. Because the leaf grows in full sun, sencha carries more catechins per gram than shaded matcha; in our most recent batch testing, our Sencha powder tested at 65 mg of EGCG per 0.75 g serving, against 122 mg per 1.5 g serving of our matcha, so per gram the sencha is slightly ahead. Those results vary by lot and by packaging, which is why we publish our lab results rather than a single number. The leaf also carries L-theanine, less than shaded leaf but enough to take the edge off the caffeine, and a modest amount of caffeine itself, about 20 mg a serving.
What the compounds do is a question for the research, not for a tea seller. Green tea catechins are among the most studied antioxidants in any food, and the largest population study of green tea drinkers, which followed more than 40,000 Japanese adults for eleven years, found that the people who drank the most green tea had the lowest rate of death from cardiovascular disease (Kuriyama et al., JAMA, 2006); the combination of a little caffeine with L-theanine is what people describe as green tea's calm alertness. I make no claims that sencha prevents or treats any disease, detoxes anything or causes weight loss; the studies behind those headlines used concentrated extracts at doses no cup of tea reaches, and their results are mixed. My longer look at the plant as a whole is on the benefits of green tea. What I will say plainly is that, of our two signature teas, sencha gives you more EGCG per gram than matcha at roughly half the caffeine and about half the price per serving, or less from the pouch, and that a cup you enjoy every day does more for you than a supplement you forget.
How much caffeine is in sencha?
Less than matcha and much less than coffee. A brewed cup of green tea, sencha included, carries 24–40 mg of caffeine per 8 oz as an industry range; our Sencha powder tests at about 20 mg per 0.75 g serving, because a serving is small and the leaf is sun-grown, which holds caffeine down, from our most recent batch testing; results vary by lot and by packaging. For comparison, our matcha tests at about 41 mg a serving and a cup of coffee runs 95–240 mg. Four or five servings of sencha spread through the day stay well under the 400 mg a day the FDA considers a safe level for healthy adults, which makes it the easier tea to drink several times a day. If you want almost none, our Organic Decaf Sencha is the same leaf decaffeinated with water alone, at about 4 mg a serving; how that works, and what the leaf keeps, is on our decaf green tea page. Every tea we make, brewed and powdered, is lined up on how much caffeine is in green tea.
Sencha powder vs loose-leaf sencha
Loose-leaf sencha is brewed and the leaf is thrown away, and that is a fine way to drink it. But catechins only partly leave the leaf in a short, cool steep, and so does much of the L-theanine. A powder you drink whole delivers everything the leaf holds, the way matcha does, which is the reason we have made our sencha as a powder since the beginning. It also whisks into cold water in a few seconds, takes a latte, and goes into cooking by the spoonful. The trade-off is texture: a powder has body and a little sediment, where a brewed cup is clear. The case for powdered green tea in general, matcha and sencha alike, is on the benefits of green tea powder.
Our Organic Sencha
Our sencha is first-harvest leaf, grown in full sun in Japan, steamed, rolled and dried in the traditional way, then stone-milled into a fine powder. It is certified organic and tested by an independent, accredited third-party lab for heavy metals, radiation and microbes, with the results published. It comes as 30 single-serve sticks of 0.75 g, or as a 100-serving pouch with a heaping ¼ teaspoon as the measure. At our current prices that is $1.03 a serving in sticks and $0.40 a serving from the pouch, and Subscribe and Save takes a further 5% to 10% off; both versions, and the decaf, are in our sencha collection. It is the tea Yu Tea started with in 2004, and it is still our signature tea.
How to drink sencha
Hot: one stick or a heaping ¼ teaspoon (0.75 g) in 6–12 oz of water at 165°F (74°C) or below, never boiling, whisked with a bamboo whisk or a frother; start with a splash of water to make a smooth paste, then top up. Cold: the same amount shaken into 8 oz of cold water, then ice; cold sencha is lighter and sweeter, with almost no astringency. Latte: a full stick, or a little more, whisked with 2 oz of water and then 6–8 oz of milk; sencha makes a lighter, brighter latte than matcha. The method, step by step, is on how to make matcha and our other teas. In the kitchen, sencha seasons rice, fish, dressings and baking without taking over; our sencha recipes start with the easy ones, and the green tea ice cream works with sencha as well as matcha.
Sencha FAQ
What is sencha tea?
Japan's standard green tea: leaf grown in full sun, steamed to keep it green, rolled into needles and dried. It accounts for more than half of the tea made in Japan and is the cup most people there drink every day.
Is sencha the same as green tea?
Sencha is a green tea, the most common kind in Japan. "Green tea" also covers shaded teas like matcha and gyokuro, roasted hojicha, and Chinese green teas, which are pan-fired rather than steamed. If a Japanese cafe serves you green tea without naming it, it is almost certainly sencha.
What does sencha mean?
Sen means to infuse or simmer and cha means tea, so sencha is "infused tea": named for being steeped in hot water, as opposed to matcha, which is whisked as a powder.
Is sencha good for you?
Sencha carries the catechins, including EGCG, that green tea is studied for, with less caffeine than matcha; population studies associate regular green tea drinking with better cardiovascular outcomes. It is not a treatment for anything, and I make no disease claims for it. Our powder tests at 65 mg of EGCG per 0.75 g serving in the latest batch.
How much caffeine is in sencha?
A brewed cup of green tea carries 24–40 mg per 8 oz, as an industry range. Our Sencha powder tests at about 20 mg per 0.75 g serving, and our Decaf Sencha at about 4 mg, from our most recent batch testing; results vary by lot and by packaging.
Sencha or matcha: which is healthier?
Neither is a medicine. Matcha gives more L-theanine and more EGCG per serving; sencha gives slightly more EGCG per gram, roughly half the caffeine and half the price or less. Choose by what you want from the cup; a common pattern is matcha in the morning and sencha through the day.
What does sencha taste like?
Bright, crisp and fresh: spring greens and cut grass, a hint of honey-like sweetness, a soft umami and a clean, slightly citrusy finish with light astringency. Lighter and less creamy than matcha.
Why does sencha grow in the sun?
Sunlight makes the plant convert L-theanine into catechins to protect its leaves, so sun-grown sencha is higher in catechins and brighter in taste than shaded matcha, which keeps its theanine and tastes sweeter and more savory. Sun also holds caffeine down.
How do you drink sencha powder?
0.75 g, one stick or a heaping ¼ teaspoon, whisked with a splash of water at 165°F or below and topped up to 6–12 oz; or shaken into 8 oz of cold water over ice. It also makes a light latte and goes into cooking.
How many cups of sencha can I drink a day?
Our guidance for any of our teas is four or five cups a day, an hour or two apart. At about 20 mg a serving, five servings of sencha are roughly 100 mg of caffeine, well under the FDA's 400 mg a day for healthy adults.
