What Is Japanese Green Tea?
Most teas come from the same plant:
👉 Camellia sinensis
The difference comes from processing:
- Green tea → steamed (fresh, slightly bitter)
- Black tea → fully oxidized (strong aroma)
- Oolong tea → partially oxidized
- Hojicha → roasted (low bitterness, low caffeine)
- Genmaicha → green tea + roasted rice
- Jasmine tea → green tea + floral scent
👉 Same leaf, completely different experience.
