gyokuro

Uji gyokuro (literally "jade dew") is the high-shaded green tea that defines the Uji region of Kyoto. Per Wikipedia: the leaves are shaded for 20+ days using reed screens, straw or shading nets, with light blocking progressively increased from 70% to 80–90%; anything shaded under 20 days is classified as kabusecha instead. The shading raises L-theanine and chlorophyll while suppressing catechin development, which is what produces gyokuro's famously thick umami-marine cup. The technique was discovered in 1835 by merchant Yamamoto Kahei after observing farmers netting plants for frost protection. Uji produces ~140 tons annually (2008 figure, second after Yame's >40% national share).

Per Wikipedia, gyokuro brews at 40-70 °C with about 5g per 150ml — radically lower water temperature than any Chinese green tea. The 2-minute first infusion extracts the umami; subsequent steeps go 20-30 seconds. Re-steeps 3-4 times.
