Understanding Tea Oxidation: The Key to Every Tea's Character
All true teas come from the same plant — Camellia sinensis. What makes white, green, oolong, and black teas so different from each other is one key variable: oxidation. Understanding oxidation unlocks the entire world of tea.

Oxidation is a chemical process that occurs when tea leaves are exposed to oxygen after picking. Enzymes in the leaf react with oxygen, changing the leaf's color, flavor, and aroma compounds. The longer the oxidation, the darker and bolder the tea.
Tea Types by Oxidation Level
| Tea Type | Oxidation Level | Flavor Profile | Caffeine |
|---|---|---|---|
| White Tea | 0-15% | Delicate, sweet, floral | Very low |
| Green Tea | 0-10% | Fresh, grassy, vegetal | Low-medium |
| Oolong Tea | 15-85% | Complex, floral to roasted | Medium |
| Black Tea | 100% | Bold, malty, robust | High |
How Oxidation is Controlled
- White & Green Tea: Heat is applied immediately after picking (steaming or pan-firing) to deactivate oxidation enzymes
- Oolong Tea: Partial oxidation is carefully controlled by the tea master
- Black Tea: Leaves are fully oxidized before drying

- Assam Green Tea: Unoxidized — fresh, brisk, malty-green character
