Sencha accounts for roughly 80% of all tea produced in Japan. If you have ever drunk Japanese green tea, chances are it was sencha. Yet most of what gets sold internationally under the sencha label barely resembles what Japanese tea drinkers actually enjoy — and the gap between mediocre sencha and the real thing is enormous.
At Valley of Tea, we source sencha directly from growers in Japan. Our sencha comes from Japan's first harvest of May — the shincha flush — where the winter dormancy concentrates amino acids and the resulting tea is noticeably softer and sweeter than later pickings. We have tasted hundreds of production lots over the years, and we know exactly what separates a flat, generic sencha from one that stops you mid-sip. This guide covers how sencha is made, the main types you will encounter, what good sencha actually tastes like, and how to brew it properly.
Sencha is a steamed green tea. That single fact — steaming rather than pan-firing — defines its character and separates it from Chinese green teas like Longjing or Bi Luo Chun.
After the leaves are plucked, they are taken to the factory and steamed within hours. Steaming halts oxidation by deactivating the enzymes in the leaf. The duration of steaming is one of the most critical decisions a producer makes, and it directly shapes the flavour profile of the finished tea.
After steaming, the leaves go through a series of rolling and drying stages. The rolling serves two purposes: it breaks down the cell walls to release flavour compounds during brewing, and it shapes the leaves into the tight, needle-like form that is characteristic of sencha. The final drying step — called "aracha" finishing — reduces moisture content to around 5%, stabilising the tea for storage.
The entire process from fresh leaf to finished tea takes only a few hours. There is no withering step, no oxidation period. This speed is deliberate. It preserves the bright green colour, the vegetal aroma, and the amino acid content that define high-quality sencha.
Most sencha comes from the Yabukita cultivar, which was developed in the 1950s and still dominates Japanese tea production. But single-cultivar sencha from varieties like Saemidori, Okumidori, Asatsuyu, and Gokou offer distinctly different flavour profiles. The cultivar matters as much as the processing.
The most important distinction in sencha is steaming duration. It divides sencha into two broad categories.
Asamushi sencha (light-steamed) is steamed for approximately 30 to 40 seconds. The leaves remain largely intact after processing — long, tight needles with a clean, defined shape. Asamushi sencha brews a pale yellow-green liquor that is clear and transparent. The flavour is crisp, with defined edges: a clean vegetal note, moderate astringency, and a refreshing finish. This is traditional-style sencha, and it rewards careful brewing.
Fukamushi sencha (deep-steamed) is steamed for 60 to 120 seconds — roughly two to three times longer than asamushi. The extended steaming breaks down the leaf structure, so the finished leaves are smaller and more fragmented. The brew is opaque, a deep, cloudy green. Fukamushi sencha tastes rounder, softer, and more full-bodied than its light-steamed counterpart. The astringency is reduced, sweetness comes forward, and the body is heavier on the palate.
Fukamushi has become the dominant style in Japan over the past few decades, particularly from the Shizuoka region. It is more forgiving to brew and appeals to a wider range of palates. Asamushi is more common in regions like Uji (Kyoto) and parts of Kagoshima, where producers lean toward a more refined, traditional style.
Neither is better than the other. They are different expressions of the same leaf. If you are new to sencha, fukamushi is generally the easier starting point. If you appreciate nuance and are willing to pay attention to your brewing parameters, asamushi rewards that attention.
Shincha — literally "new tea" — is the first harvest sencha of the year, picked in late April and May. It is not a different type of sencha in terms of processing. What makes it distinct is timing.
Tea bushes accumulate nutrients over the winter dormancy period. The first flush of spring growth is rich in amino acids, particularly L-theanine, and lower in catechins compared to later harvests. The result is a tea that tastes sweeter, more vibrant, and less astringent than sencha made from the same field later in the season.
Shincha is seasonal and limited. In Japan, its arrival is anticipated the way Europeans anticipate the first asparagus of spring. It is meant to be consumed fresh — within weeks of production, ideally — and it does not improve with age.
We offer shincha when it is available, but it sells out quickly. If you see it, buy it and drink it promptly.
Describing sencha flavour in general terms is a bit like describing wine — the range is wide. But there are common markers.
Good sencha balances three elements: umami (savoury depth), astringency (a clean, drying sensation), and sweetness (not sugar-sweet, but a rounded, almost buttery quality). The interplay between these three determines the character of any particular sencha.
In our range, the May first-harvest sencha sits firmly on the sweeter, softer side — the umami is present but not heavy, the astringency is low, and the finish is clean with a mellow, fresh-cut grass quality. This is what a first-flush steamed tea tastes like when it has not spent months in a warehouse.
High-grade sencha from early spring harvests leans heavily toward umami and sweetness. The amino acid content is high, the catechin content lower. These teas can taste almost brothy, with a marine quality that sometimes surprises first-time drinkers.
Later-harvest sencha and lower-grade production tilts toward astringency and bitterness. The catechins have increased, the amino acids decreased. These teas are sharper and thinner, which is not necessarily bad in small doses but becomes unpleasant in poor-quality versions.
Aroma is another dimension. Fresh sencha should smell green and alive — steamed greens, cut grass, sometimes a hint of seaweed or toasted nori. Stale sencha smells flat, papery, or like dried hay. If your sencha does not smell vibrant when you open the packet, it has lost its best qualities.
Colour of the brewed liquor varies by type: pale gold-green for asamushi, deep opaque green for fukamushi. But regardless of type, the colour should look vivid, not dull or brownish. Brown-tinged liquor indicates stale or improperly stored tea.
Sencha is sensitive to brewing parameters. The difference between a perfectly brewed cup and a bitter, undrinkable one is often just 10°C or 30 seconds. Here is what works.
Water temperature: 70°C to 80°C for most sencha. This is well below boiling. Using boiling water on sencha extracts excessive catechins and caffeine, producing harsh bitterness that overwhelms the tea's subtlety. Higher-grade sencha benefits from the lower end of this range (70°C). Everyday sencha does fine at 80°C. Fukamushi is slightly more tolerant of higher temperatures than asamushi.
Leaf quantity: 4 to 5 grams per 150 ml of water. This is roughly one heaped teaspoon for most sencha, though fukamushi (being more broken) packs more densely. Use a scale if you have one — it removes guesswork.
Steep time: 60 to 90 seconds for the first infusion. Do not walk away and forget about it. Sencha punishes over-steeping.
Second and third infusions: Good sencha gives you at least two, often three infusions. For the second, use slightly hotter water (80°C to 85°C) and a shorter steep — 30 to 45 seconds. The second cup often reveals different aspects of the tea, sometimes a more savoury character.
Teaware: A Japanese kyusu (side-handle teapot) with a built-in mesh strainer is ideal. The wide, flat shape allows the leaves to open fully. A small ceramic teapot works fine too. Avoid infuser balls — they restrict the leaves and produce inferior extraction.
Water quality: Use filtered water or good-quality spring water. Hard water flattens the flavour. Chlorinated tap water is the enemy of delicate green tea.
One common mistake: pre-warming the cup with hot water. This is not ritual for ritual's sake — it keeps the temperature stable during the steep, which matters when you are working with 70°C water that cools quickly. For a full walkthrough on technique, see our guide on how to make sencha tea.
Sencha contains caffeine. A typical cup (150 ml brewed from 4 grams of leaf) delivers approximately 30 to 50 mg of caffeine, depending on the grade, harvest season, and brewing parameters.
For comparison: a standard cup of coffee contains 80 to 120 mg. So sencha delivers roughly a third to half the caffeine of coffee.
Several factors influence caffeine content in sencha. Younger leaves and buds contain more caffeine than mature leaves. First-harvest (shincha) sencha is higher in caffeine than later harvests. Hotter water and longer steep times extract more caffeine.
Fukamushi releases its contents faster due to the broken leaf structure, which can mean slightly more caffeine per cup at the same steep time.
The practical effect for most drinkers: sencha provides a noticeable lift without the jittery edge that coffee can produce. The L-theanine in sencha — an amino acid that promotes calm focus — modulates the caffeine effect. Research published in Scientific Reports confirms that green tea consumption, including sencha, produces measurable effects on stress response and mental performance in healthy adults. Many drinkers report a more sustained, even energy compared to coffee. This is subjective, but it is consistent enough across reports to be worth noting.
If you are caffeine-sensitive, brew at lower temperatures and shorter times, and favour later-harvest sencha over spring first flush. For an even lower-caffeine option from the same Japanese tea tradition, our Kukicha — made from stems and twigs of the tea plant — delivers a naturally sweet cup with minimal caffeine.
Most sencha available outside Japan is mediocre. It has been sitting in warehouses, passed through multiple intermediaries, and lost its freshness long before it reaches you. Here is what to look for.
Freshness is non-negotiable. Sencha starts declining the moment it is produced. Vacuum-sealed, properly stored sencha stays good for several months. Once opened, use it within three to four weeks for best results. Avoid any sencha without a clear production or harvest date. "Best before" dates two years in the future are a red flag — that tea was old before it was packed.
Origin specificity matters. "Product of Japan" tells you almost nothing. Look for the region (Shizuoka, Kagoshima, Uji, Yame), the cultivar if listed, and the harvest season. According to the Global Japanese Tea Association, sencha still accounts for more than half of Japan's total tea production — which means quality varies enormously across the category. The more specific the sourcing information, the more likely the seller knows and cares about what they are selling.
Leaf appearance tells a story. Good sencha has tight, uniform needles with a deep green colour. Broken, dusty leaves with a yellowish or brownish tint indicate low grade or poor handling. Fukamushi will naturally be more broken, but even then, the colour should be a vivid green.
Price is a signal, not a guarantee. Very cheap sencha is almost always low-quality late-harvest tea. But expensive sencha is not automatically good — marketing budgets can inflate prices without improving the tea. The sweet spot for everyday drinking sencha is mid-range. Competition-grade first flush is a worthwhile splurge for special occasions.
Direct sourcing changes everything. This is where we are biased, but the bias comes from experience. At Valley of Tea, we work directly with Japanese growers. There are no brokers or trading houses in between.
The teas we select are the product of generations of artisan farming — families who have refined their processing over decades, and whose knowledge shows in the cup in ways no commodity auction lot can replicate. This means fresher tea, clearer traceability, and better value at every price point. When you shorten the supply chain, quality goes up and the grower gets a better deal too.
If you want to explore the full range of Japanese green tea styles, our Gyokuro is shaded before harvest to amplify L-theanine to exceptional levels — the umami is intense and the cup is silky. For something more accessible, our Genmaicha blends sencha with roasted brown rice for a nutty, warming character that is a natural entry point for new drinkers. Those who enjoy lighter, everyday Japanese green tea might also appreciate our Gunpowder Green Tea — a different style, pan-fired rather than steamed, but equally rewarding when brewed with care.
A 2025 study on the stress-relieving effects of Japanese green teas found that superior and deep-steamed sencha grades carry higher concentrations of theanine and arginine the amino acids responsible for calm focus compared to standard grades. This is the biochemical basis for what experienced sencha drinkers already know from the cup: quality matters, and the gap between grades is real.
Sencha is not complicated, but it is precise. The steaming, the cultivar, the harvest timing, the brewing temperature — each variable matters, and getting them right transforms a simple green tea into something distinctive.
If you have only ever had flat, bitter green tea and wondered what the fuss was about, you have not had good sencha. Start with a properly sourced fukamushi, brew it at 75°C for 70 seconds, and pay attention. The difference is immediate and obvious.
We have built Valley of Tea around that difference. Every sencha in our range was selected because it represents what sencha should taste like — not what most of the market settles for. Try it, and you will understand why Japan drinks more of this tea than any other.
