Uji, Kyoto Prefecture — gyokuro technique developed 1830s; Uji remains primary production region
Gyokuro (玉露, jade dew) is Japan's most expensive green tea — grown under 90% shade for the final 3 weeks before harvest, which dramatically increases L-theanine amino acids (creating profound umami and sweetness) while reducing catechins (bitterness) and increasing chlorophyll (deep green color). The shading transforms the flavor profile entirely: gyokuro has almost no bitterness, extraordinary umami sweetness, oceanic mineral notes, and a fragrance unlike any other tea. Brewing requires extremely cool water (50-60°C) and short steep (90 seconds). The used leaves (ochadashi) after brewing are seasoned with soy and eaten as a salad.
Profound umami sweetness, no bitterness, oceanic mineral depth — the most complex Japanese tea
{"Shade covering 3 weeks before harvest: black cloth increases L-theanine conversion","Water temperature 50-60°C: cooler than any other green tea for maximum sweetness","Steep time 90 seconds: not more — gyokuro extracts quickly at any temperature","Leaf to water ratio: 5-6g per 60ml — very concentrated proportion","Multiple infusions: 3-4 good steepings, each slightly hotter than previous","Ochadashi (used leaves): season with soy sauce, eat as vegetable — complete zero-waste"}
{"Ultimate temperature test: cup warmed hands — if comfortable holding, water is correct temperature","Gyokuro ice: brew gyokuro cold with one ice cube drop at a time until melted","Premium gyokuro from Uji: drink with wagashi — the tea-sweet balance is the experience","Ochadashi salad: blanched tea leaves dressed with sake-soy and sesame — complete umami dish","Kabusecha (briefly shaded): middle ground between gyokuro and sencha — more accessible price"}
{"Hot water with gyokuro — bitterness dominates and destroys the umami sweetness","Too long steep — over-extraction creates harsh vegetal bitterness","Too much water — gyokuro should be a small, concentrated cup, not dilute","Wasting used leaves — ochadashi is a complete side dish itself"}
