  • Green Tea: 80-90℃ (electric pan), 30-45mins; stir every 15mins to avoid scorching . Function: Inactivates polyphenol oxidase to retain grassy freshness and green hue.
  • Black Tea: 110-120℃ (gross fire, 15mins) → 85-95℃ (full fire, 10-20mins); cool 2hrs between stages . Function: Triggers theaflavin formation for rich, malty flavor.
  • Oolong (Yancha): Charcoal ashes heated 12hrs to white; 90-120℃, 4-36hrs (3 rounds max); flip every 30mins . Function: Develops "yan yun" (rock aroma) and reduces vegetal notes.
  • Pu’er: 60-70℃ (low-fire), 2-4hrs; spread 2cm thick . Function: Removes mustiness without destroying aging potential.
  • White Tea: 70-80℃, 1-2hrs; no stirring . Function: Preserves natural sweetness while evaporating excess moisture.
