QUICK ANSWER
Green tea preserves the natural compounds of the tea leaf by preventing oxidation through heat. This minimal processing retains high levels of catechins, particularly EGCG (epigallocatechin gallate), making green tea one of the most potent sources of antioxidants in the diet.
What Makes Green Tea Special
01Green tea preserves the natural compounds of the tea leaf by preventing oxidation through heat. This minimal processing retains high levels of catechins, particularly EGCG (epigallocatechin gallate), making green tea one of the most potent sources of antioxidants in the diet. Its fresh, sometimes grassy flavor reflects the pure essence of the tea plant.
Processing Methods: Pan-Firing vs Steaming
02| Method | Technique | Flavor Profile | Examples |
|---|---|---|---|
| Chinese (Pan-Firing) | Leaves heated in woks or drums | Toasty, nutty flavors, yellowish liquor | Dragon Well, Gunpowder |
| Japanese (Steaming) | Leaves steamed immediately | Vegetal, marine notes, bright green | Sencha, Gyokuro |

- Re-steeping: Most can be steeped 2-3 times
Specific Brewing Temperatures
