Tried a number of variations and found that whether brewing gongfu or western, water should be very hot to boiling (definitely no lower than 90 C) and start out with a fairly long first infusion – 1 min in gaiwan, 3 minutes western. Lower temps and shorter brewing times just don’t bring out the flavors.
Gongfu (90 C, 3g, 50ml) – start with 1 min steep, then 30, then adding 10/15 seconds after. First infusion has a light, buttery aroma & flavor at front, then sweet florals, then creamy finish. Aftertaste keeps creamy, sweet, floral. Second steep brings out honey/syrupy aroma, and honey is now present with the buttery florals. Finish is honeysuckle & a little cashew? Third steep keeps these flavors & adds a hint of grassy bitterness in the middle, which then complicates the previously smooth finish. By steep 5 the creamy flavors & textures are receding, giving a “cleaner” finish. By 7 & 8, the grassy florals are growing, a bit more bitterness, but still pleasant. Steep 9 has first hint of dryness. These impressions remain through 10-12, but it seems like a tiny bit of smooth creaminess returns on the finish with these. Flavors overall are growing weaker by 12, so stopped there.
Western (boiling, 4g, 250ml) – start with 3 minutes, adding 1 min after.
Has pretty much all the same flavors & aromas as in gongfu, but not as layered. Starts creamy & buttery floral, sweeter florals in middle, lingering aftertaste of sweet floral & buttery cashew nuttiness. Second steep has less floral, less butter, but still creamy, nutty, and a little grassy sweetness. Steeps 3 & 4 are about the same, just growing a little thinner & losing flavor by 4.
Cold brew – 1g/100ml, overnight chill. Quite nice flavor, though creamy butter might be a tiny bit rich as iced tea. Florals present but not as strong, very smooth overall.
