Green Tea vs Black Tea: What Actually Differs
Same plant, different processing. Here is how oxidation changes flavor, caffeine, brewing and which to start with.

Key takeaways
- Both come from Camellia sinensis; oxidation is the dividing line.
- Black tea is more forgiving to brew, green tea rewards precision.
- Caffeine overlaps heavily — preparation matters more than color.
Processing
Green tea is heated soon after picking to halt oxidation, keeping fresh, vegetal, marine notes. Black tea is rolled and fully oxidised, developing malt, stone fruit and cocoa.
Brewing differences
Green wants cooler water and short steeps. Black wants near-boiling water and three to four minutes. Swap those and both will disappoint you.

Which should a beginner buy first?
If you are coming from builder's tea, start with a loose-leaf Assam or Ceylon — familiar territory, obvious upgrade. If you already drink bagged green, buy a good sencha and taste what temperature control does.

Frequently asked questions
- Which has more caffeine?
- Typically black, but a strongly brewed green can exceed a weak black. Leaf quantity and steep time dominate.
- Can I add milk to green tea?
- It is unusual but not wrong. Roasted greens like hojicha take milk surprisingly well.
