- Green tea is the least-oxidized of the six tea classes: leaves are heated within hours of picking to halt enzymatic browning, preserving fresh vegetal flavors and most of the leaf’s natural catechins.
- The defining split is the kill-green method. Most Chinese greens are pan-fired in hot woks, giving nutty, chestnut-like depth; nearly all Japanese greens are steamed, giving grassy, marine brightness.
- China produced over 90 percent of the world’s green tea in 2024, and green tea makes up about 55 percent of Chinese output; the FAO put total world tea production at 7.1 million tonnes that year.
- Water temperature decides the cup: 75–85C suits pan-fired styles like Longjing, standard sencha runs best near 80C, and shaded gyokuro wants 60–70C, because catechin bitterness extracts sharply above 80C.
- Top-grade Mingqian West Lake Longjing, picked before the Qingming festival in early April, sells for roughly 300 to 3,000 yuan per 100 grams — about four times the price of later pickings.
Every green tea on earth starts with the same race against the clock. Within hours of plucking, the leaf must be heated — wok-fired in Hangzhou, steamed in Uji — or its own enzymes will begin oxidizing it toward black tea. That single intervention, called kill-green (shaqing in Chinese), defines the entire class. What happens in those few minutes of heat separates a flat, jade-colored Longjing from a needle-shaped, ocean-scented sencha, and explains why two teas from the same plant can taste of roasted chestnuts and steamed greens respectively.
This guide covers green tea as a class: how it is made, the benchmark Chinese and Japanese styles and how to tell them apart, brewing parameters that actually work, and what to look for when buying. Japan’s six major styles get a fuller treatment in our guide to the types of Japanese green tea, so the emphasis here falls on the Chinese classics that rarely get the same depth in English.
What Is Green Tea?
Green tea is tea whose oxidation has been stopped almost before it begins. Freshly plucked leaves of Camellia sinensis contain polyphenol oxidase, the enzyme that browns a cut apple; left alone, it would darken the leaf and transform its flavors. Heat applied soon after plucking denatures the enzyme, locking in green color, fresh aroma and a high share of the leaf’s original catechins. Everything else — shaping, drying, grading — happens after that decisive step.
The scale of the category is easy to underestimate. According to the FAO, world tea production reached 7.1 million tonnes in 2024, with China growing 53 percent of it, and green tea now accounts for roughly a third of all tea produced globally. About 55 percent of China’s enormous harvest is green tea, and China alone produced more than 90 percent of the world’s green tea in 2024. Japan, Korea and Vietnam supply most of the rest, each with distinct processing traditions.
A Short History of the Class
Green tea is the oldest finished form of tea in China, where loose-leaf pan-firing matured centuries before oxidized classes emerged. The craft remains living heritage: in November 2022, UNESCO inscribed Traditional Tea Processing Techniques and Their Associated Social Practices in China on the Representative List of Intangible Cultural Heritage, a joint file of 44 elements that includes the green tea processing techniques of West Lake Longjing.
Japan received tea from China through Buddhist monks and then took the class in its own direction. The steamed sencha method associated with Nagatani Soen dates to 1738 in Ujitawara, near Kyoto, and steaming has defined Japanese green tea ever since. The result is a rare split within one tea class: two mature traditions, one leaf, and two completely different flavor worlds.
The Kill-Green Split: Pan-Firing vs Steaming
Chinese producers overwhelmingly fix their leaf in metal — historically a hand-worked wok, today often a mechanized drum. Contact with hot metal drives off moisture while generating gentle roasted notes: chestnut, toasted grain, warm beans. Wok work is also where many famous shapes are formed. The UNESCO file documents West Lake Longjing’s pan-firing as a system of ten core hand movements — shaking, leading, squeezing, throwing, straightening, expanding, hooking, grasping, pressing and grinding — through which the maker presses the leaf flat against the wok wall as it dries.
Japanese producers steam instead. A brief blast of steam fixes the leaf in seconds without any roasted character, preserving deep green color and a grassy, marine, umami-leaning profile. Steaming time is a style dial of its own: asamushi (light steaming) keeps leaves intact and the cup clear and delicate, while fukamushi (deep steaming) breaks the leaf down for a cloudier, fuller, sweeter liquor. A smaller number of greens in both countries are fixed with hot air rather than wok contact, but pan and steam remain the two poles of the class.
The Benchmark Chinese Green Teas
Longjing (Dragon Well)
Longjing from the hills west of Hangzhou is China’s most celebrated green tea. Genuine West Lake Longjing is a protected geographic-origin product, with the wider designation split across the West Lake, Qiantang and Yuezhou production regions and the most coveted leaf coming from five classic West Lake zones: Shifeng (Lion Peak), Longjing village, Yunqi, Hupao and Meijiawu. Two cultivars dominate: the early-budding Longjing 43 and the older Qunti bush stock, whose limited old plantings in the Shifeng core are especially prized. Expect flat, smooth, spear-shaped leaves and a mellow cup of toasted chestnut and fresh beans. Our Longjing tea village day trip guide covers visiting the source itself.
Biluochun
Biluochun means green snail spring, after leaves rolled into tight spirals and picked so early they are still covered in downy white hairs — the more fuzz, the higher the grade. It comes from the Dongting mountains, Dongshan and Xishan, beside Lake Tai near Suzhou in Jiangsu province. Tasters distinguish the two banks: Dongshan leaf tends darker and larger with a richer taste, Xishan leaf smaller and more tender with a gentler one. Either way this is the opposite pole from Longjing — downy and aromatic rather than flat and toasty.
Taiping Houkui
From Anhui province comes the most dramatic leaf in green tea. Taiping Houkui is plucked from Shi Da Cha, a large-leaf tea variety found only in Anhui, and finished as enormous flattened blades up to 15 centimeters long — the classic description is two knives and one pole, meaning two straight leaves clasping a single downy bud. The outsized leaf brews a soft, sweet, remarkably smooth cup that looks like nothing else in the glass.
Anji Baicha
Anji baicha, from Anji County in Huzhou, Zhejiang, confuses buyers by name: baicha means white tea, but this is a true green, named for the unusually pale color of its spring leaves. Its calling card is chemistry. The leaf carries an amino acid content of roughly 5 to 10.6 percent, three to four times that of a typical green tea, which translates into a strikingly sweet, savory, almost brothy cup with very little bitterness.
| Style | Home region | Dry leaf | Cup character |
|---|---|---|---|
| Longjing | Hangzhou, Zhejiang | Flat, smooth spear-shaped blades | Toasted chestnut, mellow, rounded |
| Biluochun | Dongting mountains, Jiangsu | Tight spirals with white down | Tender, aromatic, gently sweet |
| Taiping Houkui | Taiping, Anhui | Pressed blades up to 15 cm | Soft, sweet, very smooth |
| Anji baicha | Anji County, Zhejiang | Slender pale-green leaves | Savory, unusually sweet, low bitterness |
| Sencha | Throughout Japan | Deep-green rolled needles | Grassy, brisk, umami-edged |
| Gyokuro | Uji and select districts | Glossy dark needles | Dense umami, low astringency |
| Matcha | Uji and other shaded districts | Stone-milled powder | Full-bodied, creamy, sweet-bitter |
Japanese Green Teas in Brief
Japan devotes nearly its whole industry to steamed greens, and the styles form a ladder of shade and processing. Sencha, the everyday standard grown in open sunlight, makes up the bulk of production; our sencha guide walks through its steaming grades, cultivars and shincha season in detail. Gyokuro spends several weeks under shade cloth before harvest, which concentrates amino acids and produces its signature buttery umami. Matcha is shaded leaf ground to powder and whisked whole. Around these three sit bancha, genmaicha and hojicha — later pluckings, roasted-rice blends and roasted styles that stretch the class from marine freshness to toasty comfort. Shizuoka, Kagoshima, and the Uji area around Kyoto are the names to know on labels.
How to Brew Green Tea, Style by Style
More green tea is ruined by boiling water than by any other mistake. The catechins responsible for astringency extract very little below 70C but extract rapidly once water passes 80C, so a 20-degree difference turns the same leaf from sweet to punishing. Pan-fired Chinese styles tolerate slightly hotter water than steamed Japanese leaf, and shaded teas want the coolest water of all — the classic Ippodo house recipe steeps sencha at 80C for exactly 60 seconds, while its gyokuro recipe drops the water to 60C and extends the steep to compensate. Quality leaf rebrews: expect two to three worthwhile infusions from Chinese greens and Japanese sencha, adding a little time to each.
| Style | Water temperature | First steep | Note |
|---|---|---|---|
| Longjing and other pan-fired Chinese greens | 75–85C | Start short and taste as you go | Often brewed loose in a tall glass, topped up as you drink |
| Sencha | About 80C; 70C for a softer cup | About 60 seconds | Hotter water sharpens it, cooler water sweetens it |
| Gyokuro | 60–70C | Longer than sencha at low heat | Above about 65C the delicate amino-acid sweetness is lost |
| Anji baicha | 75–80C | Start short and taste as you go | High amino acids keep it sweet even if slightly oversteeped |
Health Benefits, Honestly Framed
Green tea’s reputation rests on its catechins, especially EGCG, which survive the kill-green step in higher amounts than in oxidized teas. Human evidence is promising in some areas and unsettled in others, and marketing routinely runs ahead of the science. Rather than repeat the claims here, we grade the research — what is well supported, what is preliminary and what is myth — in our evidence-based guide to green tea benefits. The short version: it is a low-calorie, moderate-caffeine drink with a genuinely interesting research profile, not a medicine.
How to Buy and Store Green Tea
Green tea is the most freshness-sensitive class, so buy current-year tea in small quantities. With Chinese greens, harvest date is the price axis. Mingqian lots, picked before the Qingming festival in early April, come from a slow-growing, tiny-yield window: genuine first-flush West Lake Longjing runs roughly 300 to 3,000 yuan per 100 grams, around four times the price of leaf picked after the festival. Yuqian lots, picked before the Grain Rain solar term later in April, deliver most of the character for far less. With Japanese greens, look for the spring shincha releases and check the packing date, not just best-before.
Authenticity matters at the top end. Far more tea is sold as West Lake Longjing than the protected zones could ever grow, so treat suspiciously cheap Shifeng or Meijiawu labels as exactly that. Once opened, green tea fades fast in light, air and heat; airtight opaque packaging in a cool cupboard is the minimum, and serious buyers refrigerate sealed, unopened leaf. Our tea storage guide covers the cold-storage rules that keep delicate greens lively for months.
Tasting Green Tea at Origin
No tasting room matches drinking a green tea within sight of its bushes. Around Hangzhou you can walk the West Lake villages, taste spring lots at farmhouse tables and watch wok-firing up close; Meijiawu and Longjing village are day-trip distance from the city center. In Japan, Uji and the surrounding hills pour gyokuro and matcha at their source, while Shizuoka’s vast fields anchor sencha country. Korea’s Boseong terraces and Vietnam’s Thai Nguyen region round out East Asia’s green tea map, each with its own cultivars and firing habits. Time a China visit for late March through April and a Japan visit for the May shincha weeks and you will taste the class at its absolute peak.

Frequently Asked Questions
What is the difference between Chinese and Japanese green tea?
Chinese green tea is usually pan-fired in hot woks, which gives toasty, nutty, chestnut-like flavors, while Japanese green tea is almost always steamed, which keeps it grassy, marine and umami-rich. The leaf shapes differ too: China produces flat blades, spirals and curled styles, while Japan mostly rolls its steamed leaf into slender needles.
What temperature should green tea be brewed at?
Most green teas brew best between 70C and 85C, never at a full boil. Pan-fired Chinese styles like Longjing take 75–85C, standard sencha runs about 80C for one minute, and shade-grown gyokuro drops to 60–70C. Cooler water matters because the catechins that cause bitterness extract slowly below 70C and rapidly above 80C.
What is the most famous Chinese green tea?
Longjing, or Dragon Well, from the hills west of Hangzhou is China’s most celebrated green tea. Its wok-pressed flat leaves and toasted chestnut flavor come from a pan-firing craft recognized by UNESCO in 2022, and its five classic West Lake zones — Shifeng, Longjing village, Yunqi, Hupao and Meijiawu — anchor a protected designation.
Is Anji white tea actually a white tea?
No — Anji baicha is a green tea from Anji County in Zhejiang, named for its unusually pale spring leaves rather than its processing. It is fixed and dried like other green teas, and its amino acid content of roughly 5 to 10.6 percent, three to four times a typical green, gives it a strikingly sweet, savory taste.
Why is Mingqian Longjing so expensive?
Mingqian Longjing is picked before the Qingming festival in early April, when buds grow slowly and yields are tiny, so genuine first-flush West Lake lots sell for roughly 300 to 3,000 yuan per 100 grams. That is around four times the price of leaf picked only weeks later, and supply from the protected core zones is fixed.
Sources: production and trade figures come from the FAO current global tea market report; the 2022 inscription and the Longjing hand-firing movements are documented in the UNESCO intangible heritage listing for traditional Chinese tea processing; Japanese brewing parameters follow producer guidance such as ITO EN’s preparation guide.
