Tea cultivation in China dates to the Tang Dynasty (618–907 CE), with Lu Yu's Chájīng (Classic of Tea, 780 CE) as the first comprehensive text. Green tea was the dominant form until the Ming Dynasty (1368–1644) when loose-leaf steeping replaced compressed tea cakes. Japan received tea cultivation knowledge from Tang Dynasty China in the 9th century via Buddhist monks. Japan's steaming tradition developed independently from China's pan-firing tradition, producing two distinct green tea cultures that persist to this day.
Green tea is the world's most consumed tea variety outside of black tea — produced from Camellia sinensis leaves that are harvested and immediately heat-treated to prevent oxidation, preserving the leaf's natural green colour, grassy-vegetal flavours, and high catechin antioxidant content. The fundamental distinction between Japanese and Chinese green tea lies in the heat-treatment method: Japanese green teas are typically steamed (producing marine, umami, grassy notes — as in Sencha and Gyokuro), while Chinese green teas are pan-fired in a wok (producing nutty, toasty, slightly smoky notes — as in Longjing and Biluochun). Green tea contains L-theanine, an amino acid that modulates caffeine's effect, producing focused calm rather than the jittery stimulation of coffee. The most famous varieties — Japan's Gyokuro, Sencha, and Kabusecha; China's Dragon Well (Longjing), Biluochun, and Xinyang Maojian — each express distinct terroir through growing altitude, shading, varietal, and picking season.
FOOD PAIRING: Japanese Sencha pairs with sashimi, lightly seasoned rice dishes, and vegetable tempura — the green tea's umami amplifies umami in the food while its grassy freshness cuts through fish oil. Chinese Longjing pairs with dim sum, steamed dumplings, and delicate chicken dishes. From the Provenance 1000, pair with cucumber and cream cheese sandwiches, steamed sea bass, or matcha shortbread. Cold-brewed Gyokuro pairs remarkably with fresh oysters.
{"Water temperature is critical: Japanese steamed green teas (Sencha, Gyokuro) require 60–75°C to prevent bitterness from excess catechin extraction; Chinese pan-fired greens (Longjing) suit 75–85°C","Never use boiling water (100°C) on green tea — tannins and catechins at high temperature produce harsh astringency that masks the tea's delicate character","First flush (spring harvest, shincha/ichibancha in Japan) is the premium harvest — young leaves have the highest amino acid content and the most delicate flavour","Brewing time: 1–2 minutes for Japanese steamed greens; 2–3 minutes for Chinese pan-fired greens — over-steeping any green tea produces bitterness","High-quality green tea (Gyokuro grade) can be brewed 3–5 times, with each subsequent infusion revealing different flavour dimensions as different compounds extract at different rates","Cold brewing green tea (overnight in refrigerator at 1:50 ratio) produces a sweeter, less bitter result that maximises L-theanine extraction while minimising catechin bitterness"}
For the definitive green tea experience: brew Gyokuro (shade-grown for 3–4 weeks before harvest, producing intensely sweet, umami-rich leaves) at 60°C for 90 seconds using a kyusu (Japanese teapot) with a 1:30 leaf-to-water ratio. The result is viscous, sweet, and oceanic — one of the world's most complex non-alcoholic beverages. Chinese Longjing (Dragon Well) from West Lake, Hangzhou, brewed at 80°C in a gaiwan reveals a toasty, chestnuts-and-spring-grass complexity unavailable in any other tea.
{"Brewing green tea with boiling water — this single error is responsible for most people's belief that green tea is bitter; temperature control is the primary skill","Over-steeping, particularly with Japanese greens that release bitterness within 3 minutes — use a timer and remove the leaves precisely","Using tap water with high chlorine or mineral content, which dramatically alters green tea's delicate flavour — filtered or soft spring water is essential"}
