In this article, we will explore:
- The differences in processing and oxidation between fresh green tea and fresh black tea

1. Understanding the Differences Between Fresh Green Tea and Fresh Black Tea
1.1 Processing and Oxidation
The biggest difference between fresh green tea and fresh black tea lies in how they are processed:
| Tea Type | Processing Method | Oxidation Level | Flavor Profile |
|---|---|---|---|
| Fresh Green Tea | Lightly steamed or pan-fired to stop oxidation | Minimal oxidation | Fresh, grassy, vegetal, slightly sweet |
| Fresh Black Tea | Fully oxidized, dried, and sometimes fermented | High oxidation | Bold, rich, malty, sometimes smoky |
- Green tea leaves retain their natural green color due to their low oxidation level.
- Black tea undergoes full oxidation, turning the leaves dark and enhancing its deep flavors.
1.2 Nutritional Composition

| Flavonoids | Moderate | High |
| Caffeine | Low to moderate (20-50 mg per cup) | High (40-90 mg per cup) |
| Theaflavins & Thearubigins | Low | High |
- Green tea is richer in catechins (EGCG), which have strong antioxidant properties.
- Black tea contains more theaflavins and thearubigins, which contribute to its bold flavor and unique health benefits.
- Black tea has higher caffeine content, making it a stronger energy booster than green tea.
