(Gongfu, 3.5g/5oz, 175, 10 sec +5 following) Dry leaves smell sweet & lightly vegetal. Wet leaves bring a touch of toasted spinach aroma.
Steeps 1-3: Aroma is of lightly buttered cooked green vegetables. Flavor is delicate, sweet, & vegetal, with a slightly thick & buttery texture. After first infusion, sweetness recedes a little while vegetal flavors grow more prominent. Remains smooth, no bitterness or astringency. After third infusion becoming a little weak.
Steeps 4-6 (30, 60, 120 sec): Not much different but definitely less strength. Longer steeps still smooth & pleasant. After 6, put leaves in ~8 oz to cold brew.
Update 1: not much left in leaves for cold brew, so iced tea was refreshing but fairly washed out.
Update 2: (Western style by pkg directions: 2.5g/8 oz/175/3 min)
Definitely not as interesting as gongfu. Aroma is similar (sweet, vegetal, pleasant), though muted. Flavors overtaken by strong green vegetable aftertaste with fair amount of (not totally unpleasant) bitterness. Prepared this way rates about 65.
Update 3: Tried cold brew from fresh – this was the best by far. Sweet & grassy refreshing, but also with umami notes of cooked green vegetables & nuttiness. Delicious – rates 90 this way.
