Sencha vs Chinese Green Tea
Japan steams its green tea; China usually pan-fires it. That single step explains most of the flavour gap.
Steaming (the Japanese method) stops oxidation quickly and keeps a vivid green colour and oceanic, grassy flavour. Pan-firing (the dominant Chinese method for teas like Longjing) adds a toasty, chestnut-like note and a yellower liquor. Japan also pan-fires a little tea โ kamairicha โ which tastes closer to the Chinese style. Brewing differs: sencha likes 70-80ยฐC and short steeps; many Chinese greens take slightly hotter water.
